There is general agreement among current workers that Hydraena is monophyletic, based on these characters (for example, Jäch et al. 2000). The Australian species meet these generic criteria.</p> <p>The division of Hydraena into subgenera is currently a matter of uncertainty. Some groupings of species into large putative monophyletic groups is more certain, but the sister group relationships of these groups are less clear, and presently under study (Ignacio Ribera and colleagues, for example, are currently doing DNA analysis). The morphological cladistic analysis of Jäch et al. (2000) concluded that "the great phylogenetic alternative" to Hydraena (s. str.) had been found in Hydraena (Hydraenopsis). The Australian species of Hydraena, with the possible exception of H. affirmata, are most probably related to species placed by Jäch et al. in Hydraena (Hydraenopsis). However, I prefer not to formally assign species to subgenera until the results of a comprehensive DNA analysis are published, and it is shown that Hydraenopsis is not nested within what is now considered Hydraena (s. str.).</p> </div>	https://treatment.plazi.org/id/038187DBFFB0FFCCFF37FF07FD323266	Public Domain	No known copyright restrictions apply.

Similar to H. reticuloides in the minute plaques; differing therefrom in the larger size (ca. 1.45 vs. 1.25 mm), and details of the aedeagus (Figs. 8, 9).</p> <p>Description. Size (length/width, mm) holotype: body (length to elytral apices) 1.45/0.63; head 0.25/ 0.37; pronotum 0.38/0.50, PA 0.40, PB 0.44; elytra 0.84/0.63. Dorsum dark brown, dull; legs brown; palpi light brown except distal 2/3 of last palpomere darker. Head and pronotum markedly microreticulate, setae short but distinctive.</p> <p>Frons punctures ca. 1xef; interstices ca. 1xpd. Mentum and postmentum microreticulate. Genae weakly raised, lacking posterior ridge. Pronotal punctures on disc slightly larger than those of frons, interstices ca. 1xpd; PF1 absent; PF2 deep, oblique, separated by less than width of a fovea; PF3 moderately deep, broad; PF4 moderately deep, broad.</p> <p>Elytral punctures slightly larger than largest pronotal punctures. Intervals not raised, very effacedly microreticulate, width about 1xpd, interstices between punctures of a row narrower, each puncture with distinctive short seta. Apices in dorsal aspect conjointly rounded, in posterior aspect margins form moderately strong angle with one another.</p> <p>Plaques nearly absent, minute ovals at posterior of shallow median depression. P1 laminate; median carina angulate in profile. P2 narrow, l/w ca. 3/1, sides parallel, apex blunt. AIS flat, width at arcuate posterior margin 2–3x P2. Protibia (male) at distal 2/3 slightly widened, with small, sharp tubercle; mesotibia simple; metatibia extremely weakly arcuate, nearly straight, without setal brush. Abdominal apex symmetrical.</p> <p>Aedeagus (Fig. 9) main-piece with small, truncate tipped process on right side, with a long cylindrical process issuing vertically from its base (visible in lateral view); left paramere angled at midlength, widened apically, setae sparse, in a row on ventral margin; right paramere widened at midlength and at apex, setae on enlarged apical part; gonopore bearing flagellum vertical. Female last tergite without incisions, with two transverse ridges, setae slender, tapering.</p> <p>Etymology. Named in reference to the reticulate dorsum and the arid region this species inhabits.</p> <p>Distribution. Currently known from the northern areas of Western Australia and Northern Territory, and northwestern Queensland (Fig. 246).</p></div> 	https://treatment.plazi.org/id/038187DBFFB5FFC8FF37FB97FDAD33F0	Public Domain	No known copyright restrictions apply.

Dorsum dark brown, lateral areas of pronotum slightly lighter, legs brown, maxillary palpi brown to testaceous.</p> <p>Frons punctures ca. 1.5xef; interstices shining, 0.5–3xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotal punctures on disc ca. 2xpd and deeper those of frons, interstices shining, 1–3xpd, punctures denser at anterior; PF1 absent; PF2 distinct, oblique; PF3 very shallow. Area between PF3 and PF4 weakly convex. Anterior margin of pronotum broadly emarginate.</p> <p>Elytral punctures about equal size of largest pronotal punctures. Intervals not raised, shining, width about 1xpd, as are interstices between punctures of a row. Apices in dorsal aspect conjointly moderately sharply rounded, in posterior aspect margins do not form angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 1/5/6/5. P1 laminate; median carina posterior extreme slightly more elevated than remainder. P2 very narrow, l/w ca. 5/1, sides parallel, apex blunt. Plaques indistinct, not well delimited laterally, punctate, located on each side of deep oval depression. No midlongitudinal carina between mesoventral intercoxal process and plaques. Carina behind mesocoxae strong. Disc of metaventrite lacking hydrofuge pubescence. AIS flat, width at straight posterior margin 5x P2. All femora thickened. Protibia widest at midlength, prominent spine on inner surface at distal 3/5. Mesotibia widest near midlength. Metatibia weakly emarginate on inner surface over distal 3/4. All tarsi short, ca. 1/3 width of pronotum. Last sternite symmetrical or nearly so; last tergite cap-like.</p> <p>Aedeagus (Figs. 27, 28) main-piece with distal extended part arcuate, continuing slightly beyond distal piece; distal piece with two lobes, the left slightly larger than the right, and with two processes on the left margin; left paramere slender, straight, much longer than right paramere, with cluster of about five setae on inner margin at apex; right paramere slightly arcuate, with setae in two groups at apex. Female last tergite with rather deep apicomedian incision delimiting two lobes, setae slender, tapering.</p> <p>Distribution. A rarely collected species, currently known from New South Wales (Fig. 254).</p> <p>Remarks. This species has been collected from streamside flood debris, wet leaf litter, and rotten wood litter, indicating that it is probably semi-humicolous in habits. The morphology concurs with this prediction, having characters similar to other Hydraena collected in litter: 1) a broad body form, 2) strong dorsal punctation, 3) short stout legs with enlarged femora and short tarsi, and 4) obsolete metaventral plaques.</p> <p>Material Examined (17): New South Wales, 48 km N Singleton, Tuglo Wildlf.

Lectotype (male): Northern Territory, Macdonnel Ranges, Reedy Creek [labels: Lectotype [written on card with specimen] // Reedy Cr. // Aedeagus drawn by P. D. Perkins // Central Ausl. coll. Horn Exp. Pres. 7-97 // HYDRAENA simplicicollis, Blackb. // Type // Lecto &amp; Paralectotype design. by P. Zwick, 1972 // DIGITAL IMAGE captured 2004 P. D. Perkins // LECTOTYPE T-13135 Hydraena simplicicollis Blackburn, 1896]. Deposited in the MVMA.</p> <p>Differential Diagnosis. Very similar in habitus to H. brittoni (Figs. 29–31); differing therefrom by the slightly wider mesoventral process (compared to the plaque width), the slightly more widely separated plaques, and the slightly coarser dorsal punctation. Reliable determinations will be based on examination of the aedeagi (Figs. 33–36).</p> <p>Description. Size: holotype (length/width, mm): body (length to elytral apices) 1.59/0.70; head 0.24/ 0.37; pronotum 0.39/0.52, PA 0.42, PB 0.48; elytra 0.95/0.70. Head dark brown to piceous, pronotum and elytra brown, anterior and posterior margins of pronotum slightly lighter, legs and palpi yellowish.</p> <p>Frons punctures ca. 1–2xef; interstices shining, 0.5–2xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotal punctures on disc ca. 1–2xpd those of frons, interstices shining, 2–4xpd, punctures denser at anterior, a few separated by narrow walls; PF1 and PF4 absent; PF2 very small, nearly absent; PF3 moderately deep.</p> <p>Elytral punctures about equal size of largest pronotal punctures. Intervals not raised, shining, width about 1xpd, as are interstices between punctures of a row. Apices in dorsal aspect conjointly rounded, in posterior aspect margins form moderately strong angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 1/.2/2.2/1. P1 laminate; median carina slightly angulate in profile. P2 moderately wide, l/w ca. 3/4, sides parallel, apex blunt. Plaques located in posterior 7/10 of metaventrite on sides of deep median triangular depression, plaques very narrow, straight, converging, anteriorly very narrowly separated. No midlongitudinal carina between mesoventral intercoxal process and plaques. AIS flat, width at arcuate posterior margin 1.5x P2. All tibiae simple, slender. Last sternite very slightly asymmetrical; last tergite with very small, slightly off-center concavity.</p> <p>Aedeagus (Figs. 33, 34) main-piece with long pointed process on right side about equal in length to right paramere, which is behind it; distal piece with several diagnostic processes; left paramere moderately wide in distal 1/2, four short, stout, arcuate setae at apex, setae along ventral margin sparse, long, and thin; right paramere somewhat knife-shaped, setae in row on ventral margin. Female last tergite with deep apicomedian incision delimiting two lobes, setae slender, tapering.</p> <p>Distribution. Rather widely distributed in eastern Queensland, plus some populations in the 'center', and one locality record each in northern Northern Territory and northern Western Australia (Fig. 249).</p> <p>Remarks. A labelling problem was encountered with the type specimens. Zwick (1977: 175) stated that the lectotype was a male from Reedy Creek; however, I found that this specimen had a paralectotype label. The specimen bearing the lectotype label was a previously undissected female which had a "Paisl Bl" [= Paisley Bluff] locality label; this specimen is designated a paralectotype in Zwick (1977). Since there is only one male with the Reedy Creek locality label, this must be the lectotype. I have therefore switched the labels, placing the lectotype label with the male, and the paralectotype label with the female. I have consulted with Ken Walker, curator at the MVMA, who concurs with the label changes.</p> <p>Material Examined (172): Northern Territory, Baramundi Creek, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=132.85&amp;materialsCitation.latitude=-12.816667" title="Search Plazi for locations around (long 132.85/lat -12.816667)">Kakadu</a> N.

Pronotal punctures on disc ca. 2xpd those of frons, interstices shining, 1–3xpd, punctures denser anteriorly and posteriorly, separated by narrow walls to 1xpd; PF1 and PF4 absent; PF2 very small, nearly absent; PF3 moderately deep, broad.</p> <p>Elytral punctures about equal size of largest pronotal punctures. Intervals not raised, shining, width about 2xpd, as are interstices between punctures of a row. Apices in dorsal aspect conjointly rounded, in posterior aspect margins form shallow angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 3/.3/8/5. P1 laminate; median carina slightly angulate in profile. P2 moderately wide, l/w ca. 3/4, sides parallel, apex blunt. Plaques located in posterior 0.7 of metaventrite on sides of deep median subtriangular depression, plaques very narrow lines, not raised, straight, converging, anterior separation ca. 1/2 posterior separation. No midlongitudinal carina between mesoventral intercoxal process and plaques. AIS flat, width at arcuate posterior margin slightly less than 2x P2. Protibia and mesotibia slender, simple; metatibia slender, medial margin with fringe of short, hair-like setae over distal 1/2. Last tergite with small apicomedian notch.</p> <p>Aedeagus (Fig. 18) main-piece with pointed process on right side about equal in length to right paramere, which is behind it; distal piece with several diagnostic processes; left paramere very wide in distal 1/2, setae sparse, long, and thin; right paramere with large lobe in basal 1/2, setae in row on ventral margin. Female last tergite with rather deep apicomedian incision delimiting two lobes, setae slender, tapering.</p> <p>Etymology. Named in reference to the metaventral plaques, which are converging lines.</p> <p>Distribution. Currently known from northwestern Queensland, northeastern Western Australia, and an intermediate locality in Northern Territory (Fig. 258).</p></div> 	https://treatment.plazi.org/id/038187DBFFA1FFDCFF37FC27FCE232B8	Public Domain	No known copyright restrictions apply.

Intervals not raised, shining, width about 1xpd, as are interstices between punctures of a row. Apices in dorsal aspect conjointly rather sharply rounded, in posterior aspect margins form very weak angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 2/2/5/4. P1 laminate; median carina angulate in profile. P2 narrow, l/w ca. 5/2, sides parallel, apex blunt. Plaques parallel, not raised, located on each side of deep depression. No midlongitudinal carina between mesoventral intercoxal process and plaques. Carina behind mesocoxae strong. AIS flat, width at arcuate posterior margin ca. 2x P2. All femora thickened. Protibia (male) widest at midlength, excavate on inner surface, prominent spine at beginning of excavation. Mesotibia simple. Metatibia nearly straight, very weakly emarginate on inner surface over distal 3/4. Last sternite almost symmetrical; last tergite notched apicomedially.</p> <p>Aedeagus (Figs. 41, 42) main-piece with distal part extended on both left and right sides, right side process in two parts, one "above" the other; distal piece with long gonopore-bearing flagellum to left of which (ventral view) is narrow process; left paramere moderately wide in lateral aspect, setae at apex and small group of short setae on dorsal margin subapically; right paramere bisinuate, setae in two groups.

C. Yeo // T.7227. // Hydraena clavigera sp. n. det. P. Zwick 1975 Holotypus]. Deposited in the QMBA.</p> <p>Differential Diagnosis. Similar to H. tricantha in body size and color (Figs. 38–40); differing therefrom by the wider pronotal base, the smaller pronotal macula, the more convex elytra, and the wider, more narrowly separated plaques. The aedeagi of the two species also suggest a rather close relationship (Figs. 43, 44, 49, 51).</p> <p>Description. Size: holotype (length/width, mm): body (length to elytral apices) 1.48/0.63; head 0.19/ 0.31; pronotum 0.38/0.49; elytra 0.91/0.63. Head dark brown; pronotum testaceous with brown macula; elytra dark brown with light brown to testaceous humeral angles and elytral apices; legs and palpi testaceous (holotype at light extreme of color variation).</p> <p>Frons punctures ca. 1xef; interstices shining, 2–3xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotal punctures on disc slightly larger than those of frons, interstices shining, 1–2xpd, punctures denser at anterior, ca. 0.5–1x diameter of discal punctures; PF1 and PF4 absent; PF2 very small and shallow; PF3 moderately deep.</p> <p>Elytral punctures ca.1xpd largest pronotal punctures. Intervals not raised, shining, width about 1xpd, as are interstices between punctures of a row. Apices in dorsal aspect gradually rounded to subtruncate, in posterior aspect margins form moderately strong angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 1/2/2/1. P1 laminate; median carina angulate in profile. P2 narrow, l/w ca. 2/1, sides parallel, apex blunt. Plaques elongate oval, located in posterior 1/2 of metaventrite on sides of deep median triangular depression, plaques not attaining anterior apex of triangle. AIS flat, width at arcuate posterior margin 2–3x P2. Protibia widened to about midlength, then markedly excavate, a prominent spine at base of excavation; meso- and metatibiae slender. Last sternite symmetrical or nearly so; last tergite with small, but rather deep apicomedian concavity.</p> <p>Aedeagus (Figs. 43, 44) main-piece with distal part greatly extended right side, apically in two parts, one "above" the other; distal piece with long gonopore-bearing flagellum to left of which (ventral view) are three or four process; left paramere moderately wide in lateral aspect, setae at apex and small group of short setae on dorsal margin subapically; right paramere produced on dorsal margin, setae in two groups. Female last tergite with apicomedian incision delimiting two lobes, setae slender, tapering.</p> <p>Distribution. Currently known from Victoria to southern Queensland, and a disjunct population in northern Queensland (Fig. 244).</p> <p>Remarks. There is variation in the aedeagal form, most notably the shapes of the processes on the left side, and the shape of the right paramere (Figs. 43, 44). The left paramere has a tiny spine-like process apically (apparently broken off in the holotype), and four long setae near midlength (also present on the holotype, not figured by Zwick (1977)). I have illustrated an aedeagal variant from Mt. Hypipamee National Park; variants intermediate between this form and the holotype have been studied.</p> <p>Material Examined (165): Australian Capital Territory, 2.5 km S of Tharwa, Naas River, 35° 31' S, 149° 4' E, 31 December 2000, W.

Similar to H. cultrata in color pattern, the pronotum usually uniformly testaceous, contrasting with the dark brown head and elytra (Figs. 66, 173); differing therefrom by the larger size (ca. 1.50 vs. 1.25 mm), the slightly less transverse pronotum (w/l ca. 1. 24 vs. 1.31), the slightly more shining dorsum, and the straight plaques. The aedeagi of the two species distinctively differ (Figs. 69, 70).</p> <p>Description. Size (length/width, mm) holotype: body (length to elytral apices) 1.47/0.58; head 0.22/ 0.33; pronotum 0.37/0.46, PA 0.38, PB 0.39; elytra 0.87/0.58.

Clypeus microreticulate. Mentum shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotal punctures on disc slightly larger than those of frons, ca. 1xef; each puncture with very fine, rather long, recumbent seta; interstices shining, on disc 2–4xpd, anteriorly and posteriorly 1–3xpd; PF1 and PF4 absent; PF2 very shallow, almost absent; PF3 shallow, broad.</p> <p>Elytral punctures slightly smaller than largest pronotal punctures. Intervals not raised, shining, width ca. 2–3xpd, as are interstices between punctures of a row. Apices in dorsal aspect conjointy rounded to subtruncate, in posterior aspect margins form strong angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 4/1/10/8. P1 laminate; median carina weakly angulate in profile. P2 moderately narrow, l/w ca. 2/1, sides parallel, apex blunt. Plaques very narrow, carinate, parallel, located on sides of deep median depression; a small "accessory plaque" on each side of anterior angle of median depression, narrowly separated from carinate plaques. AIS flat, width at arcuate posterior margin 2x P2. Profemur with tiny acute tubercle on medial margin at about basal 1/3. Protibia thick, gradually widened from base to about distal 2/3, then excavate on medial margin; mesotibia simple. Metatibia slender, inner margin (microslide mount) with few, widely spaced, long, very fine hair-like setae over basal 1/2, apical 1/2 with widely spaced, short, stout spines. Last sternite very slightly asymmetrical, produced in small rounded point; last tergite with off-center, deep concavity.</p> <p>Aedeagus (Fig. 70) main-piece with large lobe on right side, bisinuate, pointed at apex, contours on side adjacent to right paramere the same as paramere contours; distal piece with thin apical lobe that extends beyond gonopore bearing flagellum; left paramere shorter and wider than right, setae in two groups; right paramere slender, nearly straight, setae in one group at weakly widened apex. Female last tergite with apicomedian incision delimiting two lobes, setae slender, tapering.</p> <p>Etymology. Named in reference to the right paramere and the adjacent, similarly contoured process of the aedeagus.</p> <p>Distribution. Currently known from Victoria, New South Wales, and southeasternmost Queensland. (Fig. 258).</p> <p>Remarks. The color of the pronotum varies from clear testaceous, without a hint of a macula, to testaceous or light brown laterally, with a brown, diffusely margined macula. In some males the "accessory plaques" are smaller than in the holotype, and sometimes one of them will be confluent with the carinate 'regular' plaques. In females studied the plaques are not carinate, although they are distinctly raised posteriorly; also, the area of the "accessory plaques" is joined to the regular plaques, forming a shiny, but sparsely punctate, angle that joins the regular plaques. There is also some variation in the details of the male genitalia; for example, the aedeagus of the single male from Macquarie Pass National Park has slightly different raised portions near the middle of the ventral surface; otherwise the aedeagus is like that of the holotype.</p></div> 	https://treatment.plazi.org/id/038187DBFF90FFEBFF37FBBAFB0636F0	Public Domain	No known copyright restrictions apply.

Deposited in the ANIC.</p> <p>Differential Diagnosis. Recognized by the combination of the large body size (ca. 1.95 mm), the shape and relative size of the pronotum, the large and well impressed pronotal foveae PF2, the large plaques, which are posteriorly carinate in males, and the unique shape of the male metatibiae (Fig. 85). The metatibiae of males are widened on the inner surface near midlength and bear a large and dense brush of setae. Differentiated from H. luridipennis, H. simplipes, and H. impercepta by the large, well delimited plaques (among other characters). Differentiated from H. pilipes and H. robusta by the narrower and differently shaped pronotum, the presence of deep pronotal foveae PF2, and form of the male metatibiae. The aedeagus of H. barbipes (Figs. 89, 90) is very distinct from those of the compared species.</p> <p>Description.

Clypeus microreticulate or micropunctulate. Mentum weakly shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotum densely coarsely punctate, punctures on disc deep, ca. 1.5–2xpd those of frons, interstices varying from narrow walls to ca. 1xpd; PF1 absent; PF2 deep, oblique oval, separated by slightly less than width of a fovea; PF3 and PF4 very shallow, broad.</p> <p>Elytral punctures slightly smaller than largest pronotal punctures. Intervals not raised, shining, width ca. 1.5xpd. Interstices between serial punctures 1xpd or slightly larger. Apices (male) in dorsal aspect separately, broadly rounded, in posterior aspect margins forming marked angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 1/1/2/2. P1 laminate; median carina slightly angulate in profile. P2 moderately wide, l/w ca. 2/1, sides parallel, apex blunt. Plaques large, located in posterior 7/10 of metaventrite on sides of deep median triangular depression, plaques roundly raised, becoming carinate at posterior extreme. No midlongitudinal carina between mesoventral intercoxal process and plaques. AIS flat, width at arcuate posterior margin ca. 2x P2. Protibia straight, gradually increasing in width apically. Metatibia weakly arcuate on lateral surface, medial surface strongly widened at midlength, with large brush of hairs from widest part to nearly apical end. Abdominal apex simple.</p> <p>Aedeagus (Figs. 89, 90) main-piece short and wide, without lobe near base, with large fingerlike, strongly sclerotized lobe on apical part, on right side of ventral surface; left paramere slightly widened in distal 1/3, with two groups of setae; right paramere triangular in proximal 2/3, becoming very narrow in distal 1/3, with two groups of setae.

Zwick 1975 [written on card with specimen] // Gayndah // LECTOTYPE designated by // On permanent loan from MACLEAY MUSEUM University of Sydney // Aedeagus drawn by P. D. Perkins // DIGITAL IMAGE captured 2004 P. D. Perkins // Hydraena luridipennis MacL. Lecto-Typus des. P. Zwick 1977] [three paralectotypes and labels on same pin]. Deposited in the ANIC.</p> <p>Differential Diagnosis. Recognized by the combination of the large body size (ca. 2.25 mm), the shape and relative size of the pronotum, the very small plaques, and the unique shapes of the male metatibiae and the female elytral apices (Fig. 86). The metatibiae of males are weakly arcuate on the lateral surface, the inner surface is gently sinuate, and bears a moderately sparse brush of hairs over the basal 2/3. Females are immediately recognized by the uniquely shaped, triangularly produced elytral apices. The body size, dorsal sculpture and plaques are similar to H. simplipes and H. impercepta, but males of those species have differently shaped metatibiae, and females have non-modified elytral apices. The aedeagi of the three species are quite distinct (Figs. 91–94, 96).</p> <p>Description. Size: Lectotype (length/width, mm): body (length to elytral apices) 2.25/0.91; head 0.37/ 0.49; pronotum 0.53/0.68, PA 0.55, PB 0.63; elytra 1.42/0.91. Dorsum brown, except head and pronotal disc dark brown or piceous, legs and palpi brown, distal 1/2 of last palpomere darker.</p> <p>Frons punctures ca. 1xef; interstices ca. 0.5 to 1xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum weakly shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotum densely coarsely punctate, punctures on disc deep, ca. 3xpd those of frons, interstices varying from narrow walls to ca. 1xpd; PF1 absent; PF2 moderately deep, separated by about width of a fovea; PF3 and PF4 moderately deep, broad.</p> <p>Elytral punctures slightly smaller than largest pronotal punctures. Intervals not raised, shining, width ca. 1.5xpd. Interstices between serial punctures 1xpd or smaller. Apices (male) in dorsal aspect separately rounded, in posterior aspect margins forming marked angle with one another.</p> <p>Plaques indistinct (see notes). P1 laminate; median carina angulate in profile. P2 narrow, l/w ca. 4/1, sides parallel or slightly diverging toward blunt apex. No midlongitudinal carina between mesoventral intercoxal process and median triangular depression. Cuticle non-asperite under hydrofuge pubescence. AIS flat, width at arcuate posterior margin ca. 3x P2. Profemur (male) with pointed tubercle on medial surface at about basal 1/3. Protibia straight, widest subapically. Metatibia weakly arcuate on lateral surface, inner surface gently sinuate, with brush of hairs over basal 1/2. Abdominal apex markedly asymmetrical.</p> <p>Aedeagus (Fig. 91, 92) main-piece tubular, with strong, arrowhead-shaped process on right side of apical part; left paramere slightly cupped, with four groups of setae; right paramere lobe-shaped apically, with two groups of setae. Female last tergite with apicomedian incision; submarginal setae stout, forming a row, tips blunt and angled ventrad; gonocoxite as illustrated (Fig. 214).</p> <p>Distribution. Widely distributed in the eastern one-half of Australia, with very disjunct locality records in western Western Australia and northern Northern Territory (Fig. 238).</p> <p>Remarks. The metaventral depression is wider and deeper in males than in females. In both sexes the plaques are reduced to a very small oval or circular area on each side of the depression, near the base; in some specimens the plaques may be difficult to see, but are indicated by the less dense hydrofuge hairs. Females have simple legs, but are immediately recognized from all others by the triangularly produced elytral apices (Fig. 86). The two very disjunct localities, Badgingarra (Western Australia) and Humpty Doo (Northern Territory) are represented by a single male each. The synonyms of this species are thoroughly discussed by Zwick (1977).</p> <p>Material Examined (1,670): Australian Capital Territory, 15.5 km W Canberra, Murrumbidge River, elev. 579.12 m, 35° 18' S, 149° 8' E, 2 January 2001, W.

Holotype (male): Queensland [labels: Queensland Blackb's Coll // luridipennis, Macl. // I 8298 Hydraena luridipennis Macl Queensland // Hydraena impercepta Zwick spec. nov. Holotypus male design. P. Zwick 1975 // DIGITAL IMAGE captured 2004 P. D. Perkins]. Deposited in the SAMA.</p> <p>Differential Diagnosis. Recognized by the combination of the large body size (ca. 2.00 mm), the absent, or nearly absent, plaques, and the unique shape of the male metatibiae (Fig. 88), which are widened on the inner surface near midlength. This species is similar in size and dorsal sculpture to H. simplipes and H. luridipennis, but differing therefrom in the shape of the male metatibiae; also differing from H. luridipennis in shape of the pronotum (Fig. 86). The aedeagi of the three species are quite distinct (Figs. 91, 93, 94).</p> <p>Description. Size: holotype (length/width, mm): body (length to elytral apices) 2.00/0.88; head 0.25/ 0.45; pronotum 0.49/0.64, PA 0.49, PB 0.59; elytra 1.29/0.88. Head and large pronotal macula dark brown, remainder of dorsum, legs and maxillary palpi brown.</p> <p>Frons punctures ca. 1xef; interstices narrow walls near eyes, 1–3xpd medially. Clypeus microreticulate laterally, finely punctate medially. Mentum shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotum densely coarsely punctate, punctures on disc deep, ca. 3xpd those of frons, interstices narrow walls to 1xpd, some interstices uniting to form short longitudinal lines; PF1 absent; PF2 shallow; PF3 and PF4 moderately deep, shallowly joined.</p> <p>Elytral punctures about 0.5xpd of largest pronotal punctures. Intervals not raised, width ca. 1xpd, interstices between punctures of a row slightly less. Apices in dorsal aspect separately rounded, in posterior aspect margins forming angle with one another.</p> <p>Metaventral disc densely punctate beneath hydrofuge pubescence, without plaques, median impression deep, longitudinal, subtriangular, basally ca. 2x P2. P1 laminate; median carina angulate in profile. P2 moderately narrow, l/w ca. 5/3, sides parallel, apex rounded. Very low midlongitudinal carina between mesoventral intercoxal process and median depression. AIS flat, width at arcuate posterior margin 2x P2. Abdominal apex with short setae; last tergite with depression on ventral face. Protibia with subapical angulation on inner surface. Mesotibia slender. Metatibia with rounded enlargement on inner surface near midlength, then tapering to apex; outer surface arcuate at base, then straight to apex.</p> <p>Aedeagus (Fig. 93) main-piece slightly wider in lateral than ventral view, with large, strong process on right side of apical part, medial margin with two points; left paramere large, with four groups of setae; right paramere narrow, with three groups of setae. Female last tergite with minute apicomedian incision, or no incision; setae stout, forming a row, tips blunt and angled ventrad.</p> <p>Distribution. Currently known from Queensland and northern Northern Territory (Fig. 241). Also present in Papua New Guinea (Perkins, unpublished).</p> <p>Remarks. In females the elytral apices are slightly more sharply rounded, the posterior declivity is not as abrupt, and the metaventral depression is not as deep as in males. Some specimens have the metaventral plaques apparent as very small, non-punctate ovals at the base of the median depression.</p> <p>Material Examined (110): Northern Territory, 1 km N of Cahills Crossing, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=132.96666&amp;materialsCitation.latitude=-12.416667" title="Search Plazi for locations around (long 132.96666/lat -12.416667)">East Alligator River</a>, 12° 25' S, 132° 58' E, 7 June 1973, Upton &amp; Feehan (2 ANIC); 10 mi E of <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=130.85&amp;materialsCitation.latitude=-13.75" title="Search Plazi for locations around (long 130.85/lat -13.75)">Daly River</a>, at light, 13° 45' S, 130° 51' E, 28 June 1972, B.

Differentiated from other large species (ca. 2.25 mm), by the relatively large size of the pronotum, its wide shape and distinctly concave anterior margin, the narrow, elongate, and widely spaced plaques, and, in males, the form and setae of the metatibiae (Fig. 97). The metatibiae of males are weakly arcuate, weakly and gradually widened from base to apex, and the inner surface bears a brush of stiff setae over the distal 2/5. The aedeagus (Fig. 95) is quite distinct.</p> <p>Description. Size: holotype (length/width, mm): body (length to elytral apices) 2.06/0.89; head 0.28/ 0.48; pronotum 0.40/0.72, PA 0.56, PB 0.62; elytra 1.27/0.89. Dorsum dark brown, head slightly darker, margins of pronotum slightly lighter, legs and palpi light brown, distal 1/2 of last palpomere darker. Pronotum very transverse, anterior margin concave, side straight in front of and behind widest part.</p> <p>Frons punctures ca. 2–3xef; interstices very narrow near eyes, 1–2xpd medially. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotum densely coarsely punctate, punctures on disc deep, ca. 3xpd those of frons, interstices 1–3xpd on middle of disc, slightly denser anteriorly and posteriorly; PF1 indicated by dense punctation; PF2 and PF4 shallow; PF3 moderately deep.</p> <p>Elytral punctures about equal size of largest pronotal punctures. Intervals narrow, not raised, width about 0.5–1xpd, as are interstices between punctures of a row; a few extra punctures near scutellum. Apices in dorsal aspect conjointly rounded, in posterior aspect margins forming angle with one another.</p> <p>Plaque/intercoxal process ratios (P2/w/l/s) ca. 1/1/5/3. P1 laminate; median carina angulate in profile. P2 moderately narrow, l/w ca. 5/1, sides parallel or slightly converging toward blunt apex. Plaques parallel or slightly convergent anteriorly, located in posterior 7/10 of metaventrite on sides of deep median elongate depression. No midlongitudinal carina between mesoventral intercoxal process and plaques. AIS flat, width at arcuate posterior margin 3x P2. Protibia thickened on inner surface near distal 3/4. Mesotibia slender. Metatibia weakly arcuate, inner surface with brush of stiff setae over distal 4/10. Abdominal apex setose, with depression on ventral face of last tergite.</p> <p>Aedeagus (Fig. 95) main-piece with very large, arrow-shaped process apically; distal piece moderately complicated, with short gonopore bearing flagellum; left paramere shorter than right and inserted more distally on main-piece; right paramere very slender, setae in one group at weakly widened apex. Female last tergite without incisions; setae stout, forming a row, tips blunt and angled ventrad.</p> <p>Distribution. Currently known from Victoria and Tasmania, and one disjunct locality in southern Queensland (Fig. 258).</p> <p>Remarks. Some specimens have the pronotal discal punctures denser than the holotype.

Last sternite symmetrical or nearly so; last tergite with small apicomedian tooth.</p> <p>Aedeagus (Fig. 108–110) main-piece with three strongly sclerotized processes, one on ventral surface near midlength, and two on right side, both (in ventral view) arcuate, sharply pointed, and of similar shape; distal piece with several irregularly shaped lobes (which vary in shape among populations), in ventral view lobes oriented toward left side, basal lobe on dorsal surface covered by arcuate setae, gonopore-bearing flagellum short, pointing toward left side; both parameres inserting near base, of about equal length; left paramere slightly widened apically and with numerous long setae, some with widened, flat tips; right paramere markedly arcuate, with cluster of unusual, distally widened and flattened setae near midlength. Female last tergite with three incisions, delimiting four lobes, setae slender, tapering; gonocoxite and spermatheca as illustrated (Figs. 215, 230).</p> <p>Distribution. Widely distributed in the eastern one-half of Australia, with populations in the 'center' and a few records in western Western Australia (Fig. 242).</p> <p>Remarks. The aedeagus shows variation in the shapes of the lobes of the distal piece and the degree of flattening of the tips of the setae. I have illustrated the holotype aedeagus and a variant from Queensland, Girraween National Park (Figs. 108–110).</p> <p>Material Examined (217): New South Wales, Armidale, 30° 30' S, 151° 39' E, 21 March 1963, C.

Deposited in the BMNH.</p> <p>Differential Diagnosis. Similar in size, color and dorsal punctation to H. rudallensis; differing therefrom by the proportionally longer elytra, and the dissimilar plaque ratios (2/1/5/2 vs. 1/1/2.2/1) (Figs. 104–107). The aedeagi of the two species markedly differ (Figs. 108–111, 113).</p> <p>Description. Size: holotype (length/width, mm): body (length to elytral apices) 1.36/0.58; head 0.20/ 0.35; pronotum 0.33/0.45, PA 0.38, PB 0.43; elytra 0.84/0.58. Dorsum brown, head and disc of pronotum piceous, legs and palpi light brown to testaceous.</p> <p>Frons punctures ca. 1xef; interstices effacedly microreticulate, weakly shining, 0.5–3xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum shining, finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotal punctures on disc ca. 1xpd of largest frons punctures, interstices weakly shining, 2–4xpd; punctures denser and slightly deeper anteriorly and posteriorly, interstices effacedly microreticulate; PF1 and PF4 absent; PF2 very shallow; PF3 shallow.</p> <p>Elytral punctures ca. 1xpd of largest pronotal punctures. Intervals not raised, weakly shining, width about 1xpd, as are interstices between punctures of a row. Each elytron with sublateral depression bordered laterally by rounded ridge. Apices in dorsal aspect conjointly rounded, in posterior aspect margins form shallow angle with one another.</p> <p>Plaque/intercoxal process ratios (P2/w/l/s) ca. 2/1/5/2. P1 laminate; median carina posterior extreme slightly more elevated than remainder. P2 l/w ca. 7/4, sides parallel, apex blunt. Plaques located in posterior 7/10 of metaventrite on sides of deep median elongate subtriangular depression; plaques widest posteriorly, narrowly separated anteriorly. AIS flat, width at arcuate posterior margin slightly less than 2x P2. Legs simple in both sexes. Last sternite of male symmetrical or nearly so; last tergite with distinctive apicomedian notch.</p> <p>Aedeagus (Fig. 111, 113) main-piece with distal process on right side, apex rounded; distal piece comparatively simplified, gonopore-bearing flagellum terminal, moderately long; left paramere very narrow, inserting near base, setae sparse, long, apical; right paramere distinctively angulate near midlength (appearing folded in lateral view), with about three long setae just before angulation. Female last tergite with three incisions, delimiting four lobes, setae slender, tapering; gonocoxite as illustrated (Fig. 216).</p> <p>Distribution.

Perkins // Hydraena australica Zwick Holo-Typus des. P. Zwick 1977]. Deposited in the ANIC.</p> <p>Differential Diagnosis. Similar in dorsal habitus to H. parciplumea; differing therefrom by the larger size (ca. 1.45 vs. 1.31 mm), the less distinctively maculate pronotum, the slightly less distinctive dorsal setae, and the wider, non-carinate plaques (Figs. 115, 117). The aedeagi of the two species distinctively differ (Figs. 114, 119, 120).</p> <p>Description. Size: holotype (length/width, mm): body (length to elytral apices) 1.45/0.62; head 0.25/ 0.35; pronotum 0.36/0.47, PA 0.39, PB 0.47; elytra 0.86/0.62. Dorsum brown, except head and disc of pronotum piceous, legs and palpi testaceous, distal 1/2 of last palpomere darker.</p> <p>Frons punctures ca. 1xef; interstices shining, 1–2xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum weakly shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotal punctures on disc slightly larger than those of frons, interstices shining, 1–2xpd, punctures sparser on disc than anteriorly and posteriorly; PF1 and PF4 absent; PF2 very shallow; PF3 shallow, broad.</p> <p>Elytral punctures on disc about 1xpd of largest pronotal punctures, becoming smaller and shallower posteriorly. Intervals not raised, shining, width about 1–2xpd, as are interstices between punctures of a row. Apices in dorsal aspect gradually, conjointly rounded, in posterior aspect margins form shallow angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 2/1/3/2. P1 laminate; median carina angulate in profile. P2 l/w ca. 5/4, sides parallel, apex blunt. Plaques narrow, located in posterior 7/10 of metaventrite on sides of moderately deep median elongate subtriangular depression, plaques slightly more narrowly separated anteriorly than posteriorly. AIS flat, width at arcuate posterior margin 1.5x P2. Legs simple. Last sternite symmetrical or nearly so; last tergite notched apicomedially.</p> <p>Aedeagus (Figs. 119, 120) main-piece with narrow, bisinuate, pointed process on right side; distal piece simple in ventral view, multi-lobed in lateral view, gonopore-bearing flagellum terminal, short; parameres inserting at about same level on main-piece; left paramere very slender, longer than right; right paramere with about four long setae on ventral margin near midlength. Female last tergite with three incisions, delimiting four lobes, setae slender, tapering; gonocoxite as illustrated (Fig. 217).</p> <p>Distribution.

Perkins // DIGITAL IMAGE captured 2004 P. D. Perkins]. Deposited in the QMBA.</p> <p>Differential Diagnosis. Among species of the parva subgroup, most similar in size, body proportions, dorsal punctation, and plaque configuration to H. ambiosina; differing therefrom by the more distinctively depressed sublateral area of the elytra, and the stronger sublateral ridge (Figs. 122, 125, 133). Examination of the quite distinct male genitalia will be necessary for reliable determinations (Figs. 126–128, 132).</p> <p>Description. Size: holotype (length/width, mm): body (length to elytral apices) 1.25/0.54; head 0.14/ 0.32; pronotum 0.31/0.42, PA 0.35, PB 0.39; elytra 0.76/0.54. Dorsum brown, margins of pronotum, legs and palpi lighter, head darker.</p> <p>Frons punctures ca. 1xef; interstices shining, 1–2xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum shining, very finely sparsely punctate; postmentum microreticulate.

Intervals not raised, shining, width about 1xpd, as are interstices between punctures of a row. Each elytron with sublateral depression, bordered laterally by rounded ridge. Apices in dorsal aspect truncate, in posterior aspect margins form moderately strong angle with one another.</p> <p>Plaque/intercoxal process ratios (P2/w/l/s) 2/1/4/4. P1 almost laminate; median carina posterior extreme not more elevated than remainder. P2 narrow, l/w ca. 2/1, sides parallel, apex blunt. Plaques narrow, straight, located in posterior 1/2 of metaventrite on sides of shallow median depression. AIS flat, width at arcuate posterior margin 2x P2. All legs simple, tibiae slender. Last tergite produced in tiny point on each side of deep apicomedian notch.</p> <p>Aedeagus (Figs. 126–128) main-piece wide, rather flat, widened on right side concealing paramere base, with very small process distally on right side; basal orifice nearly symmetrical in ventral view; distal piece comparatively simple, gonopore bearing flagellum short, terminal; parameres inserting at same level; left paramere very slender, setae apical; right paramere sinuate in ventral view, markedly tapering to fine tip in lateral view, about four or five setae clustered on ventral margin near midlength. Female last tergite with three incisions, delimiting four lobes, setae slender, tapering.</p> <p>Distribution.

Externally very similar to H. extorris; differing therefrom by the slightly coarser punctation, the slightly different plaques, and, in males, the more strongly arcuate protibiae (Figs. 157, 159). The aedeagi of the two species differ markedly (Figs. 161, 164).

Clypeus microreticulate. Mentum and postmentum dull, microreticulate. Genae weakly raised, lacking posterior ridge. Pronotal punctures on disc 2–3xpd and deeper than those of frons, interstices shining, varying from narrow walls forming reticulate pattern anteriorly and posterior, to 1xpd on disc; PF1 absent; PF2 small, shallow; PF3 moderately deep, broad; PF4 shallow.</p> <p>Elytral serial punctures very regular, about equal size of largest pronotal punctures; intervals not raised, shining, width ca. 1xpd, as are interstices between punctures of a row; apices in dorsal aspect conjointly rounded, in posterior aspect margins form shallow angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 2/2/11/4. P1 laminate; median carina angulate in profile. P2 l/w ca. 5/2, sides parallel or slightly divergent, apex blunt. Plaques located in posterior 3/5 of metaventrite at margin of median triangular depression, plaques straight, very narrowly separated anteriorly, each plaque with lateral margin gradual, medial margin abrupt. AIS flat, width at arcuate posterior margin ca. 2x P2. Profemur (male) with sharp tubercle on medial margin at about basal 1/3. Protibia arcuate, slightly thickened in distal 1/2; mesotibia simple; metatibia slender, medial surface very weakly emarginate over distal 2/3. Last sternite with off-center lobe that fits into counterpart emargination of last tergite.</p> <p>Aedeagus (Fig. 161, 162) main-piece subtubular, without process on right side; base slightly asymmetrical; distal piece terminally with two processes, gonopore on thin process angled toward left side, other process lobe-shaped and angled toward right side; left paramere much longer than right, angularly produced on ventral surface, setae in one group, more-or-less in a line; right paramere short, simple, setae in two groups. Female last tergite with three incisions, delimiting four lobes, setae slender, tapering.</p> <p>Etymology. "No bent arm"; named in reference to the lack of an arm-shaped process on the aedeagus, such as is present in H. hamifera.</p> <p>Distribution. Currently known from southern New South Wales, Australian Capital Territory, and one disjunct locality in southern Queensland (Fig. 259).</p> <p>Remarks. There is variation in the shape of the distal piece of the aedeagus. A variant from Wombat Creek, ACT is illustrated (Fig. 162); this variant is drawn at a slightly different orientation than the drawing of the holotype (Fig. 161), illustrating how some variants will seem more markedly different if viewed at a slightly different angle than the compared specimen.</p></div> 	https://treatment.plazi.org/id/038187DBFFE7FF9AFF37FF07FD1731C8	Public Domain	No known copyright restrictions apply.

Larson (4 QMBA).</p> <p>Differential Diagnosis. Externally somewhat resembling H. inancala; differing therefrom by the narrower body form, and the coarser pronotal punctation (Figs. 157, 168). The aedeagus shows some similarity, in the shape of the distal piece, to that of H. inancala, but the main-piece is very different, having a large,</p> <p>markedly arcuate (nearly forming a circle) process and being, in that regard, more similar to the aedeagus of H. hamifera (Figs. 161, 166, 167).</p> <p>Description. Size (length/width, mm) holotype: body (length to elytral apices) 1.61/0.63; head 0.27/ 0.38; pronotum 0.38/0.52, PA 0.42, PB 0.44; elytra 0.98/0.63. Head dark brown to piceous; pronotum and elytra dark brown; legs brown; palpi light brown to testaceous, tip of last palpomere not darkened.</p> <p>Frons punctures ca. 1xef; interstices weakly shining, 1–2xpd. Clypeus microreticulate. Mentum shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotal punctures dense, 2–3xpd and deeper than those of frons, interstices shining, narrow walls forming reticulate patter; PF1 and PF4 absent; PF2 small, shallow; PF3 moderately deep, broad.</p> <p>Elytral serial punctures very regular, about equal size of largest pronotal punctures; intervals not raised, shining, width less than puncture diameter, as are interstices between punctures of a row; apices in dorsal aspect conjointly rounded, in posterior aspect margins form shallow angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 2/2/11/4. P1 laminate; median carina angulate in profile. P2 l/w ca. 5/2, sides parallel or slightly divergent, apex blunt. Plaques located in posterior 3/5 of metaventrite at margin of median triangular depression, plaques straight, very narrowly separated anteriorly, each plaque with lateral margin gradual, medial margin abrupt. AIS flat, width at arcuate posterior margin ca. 2x P2. Profemur (male) with minute tubercle near base. Protibia arcuate, slightly thickened in distal 1/2; mesotibia simple; metatibia slender, medial surface very weakly emarginate over distal 2/3. Last sternite with small apical lobe; last tergite emarginate.</p> <p>Aedeagus (Fig. 166) main-piece with large, arm-shaped process on right side that almost forms a circle; base markedly asymmetrical; distal piece with two processes, gonopore on thin process angled toward left side, other process lobe-shaped and angled toward right side; left paramere about same length as right, angularly produced on ventral surface, setae in two groups; right paramere arcuate, setae in two groups. Female last tergite with three incisions, delimiting four lobes, setae slender, tapering.</p> <p>Etymology. Named in honor of the collector and noted Dytiscidae specialist, David Larson.</p> <p>Distribution. Currently known only from the Windsor Tablelands, northeastern Queensland (Fig. 254).</p></div> 	https://treatment.plazi.org/id/038187DBFFD9FFA4FF37F917FA623588	Public Domain	No known copyright restrictions apply.

Larson (1 MCZ).</p> <p>Differential Diagnosis. An unusual species (Fig. 169), recognized by the densely coarsely punctate dorsum, the wide explanate elytral margins that have a serrated border, the raised even-numbered elytral intervals, and the small, widely spaced plaques. The very unusual aedeagus (Fig. 170) does not suggest a close relationship with other Australian Hydraena.</p> <p>Description. Size (length/width, mm) holotype: body (length to elytral apices) 1.77/0.75; head 0.29/ 0.43; pronotum 0.42/0.60, PA 0.49, PB 0.50; elytra 1.09/0.75. Dorsum dull, markedly punctate, each puncture with a distinctive, short seta. Head piceous; pronotum dark brown, anterior angles lighter; elytra dark brown; legs light brown; palpi light brown to testaceous, tip slightly darkened. Dorsum dull, markedly punctate, each puncture with a distinctive, short seta.</p> <p>Frons punctures ca. 3–4xef; interstices narrow walls to 0.5xpd. Clypeus microreticulate. Mentum and postmentum dull, microreticulate. Genae raised, with posterior ridge. Pronotal punctures very large and dense, slightly larger and deeper than those of frons, interstices narrow walls forming reticulate pattern; PF1 absent; PF2 moderately deep, oblique; PF3 and PF4 moderately deep.</p> <p>Elytral punctures ca.1xpd or slightly larger than largest pronotal punctures, very closely spaced, interstices and intervals less than 1xpd. Even-numbered intervals very weakly raised on disc, slightly higher laterally. Explanate margin wide, border finely serrate. Apices in dorsal aspect weakly separately rounded, in posterior aspect margins form strong angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 2/1/2/6. P1 laminate; median carina angulate in profile. P2 narrow, l/w ca. 2/1, sides very weakly converging, apex blunt. Plaques very small, widely separated ovals at posterior sides of deep median subtriangular depression that has midlongitudinal groove. AIS concave, width at straight posterior margin 3x P2. Protibia (male) arcuate, distal 1/4 widened in ridge-like medial margin; meso- and metatibiae slender, metatibia very weakly emarginate on medial margin. Last tergite with large apicomedian concavity.</p> <p>Aedeagus (Fig. 170) main-piece with large lobe on right side that terminates in an arcuate, sharply pointed process; distal piece with two lobes that together enclose a circular space; gonopore-bearing flagellum shorter than terminal lobe; left paramere short, rod-shaped, with sparse setae; right paramere very elongate, very thin except widened in distal 1/4, with sparse setae apically. Female last tergite with three incisions, delimiting four lobes, setae slender, tapering; gonocoxite and spermatheca as illustrated (Figs. 220, 226).</p> <p>Etymology. Named in reference to the shape of the aedeagus, part of which is suggestive of an index finger and thumb enclosing a circle (the "A-OK" symbol).</p> <p>Distribution. Currently known from northeastern Queensland and one disjunct locality in northern Northern Territory (Fig. 254).</p></div> 	https://treatment.plazi.org/id/038187DBFFD8FFA2FF37F93AFE1C30D8	Public Domain	No known copyright restrictions apply.

Size (length/width, mm) holotype: body (length to elytral apices) 1.40/0.58; head 0.23/ 0.34; pronotum 0.35/0.45, PA 0.38, PB 0.43; elytra 0.85/0.58. Head dark brown to piceous; pronotum with dark brown macula surrounded anteriorly and posteriorly by testaceous, middle 1/3 of length, between macula and lateral margin, of intermediate color; elytra dark brown; legs and palpi testaceous, tip of palpi not darker.</p> <p>Frons effacedly microreticulate, punctures less than 1xef; interstices weakly shining, 2–6xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum shining, very finely sparsely punctate; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotal punctures on disc only slightly larger than those on frons, interstices shining, ca. 2–6xpd; punctures larger anteriorly and posteriorly, ca. 2xpd of discal punctures, interstices ca. 1xpd; PF1 and PF4 absent; PF2 very shallow, almost absent; PF3 shallow, broad.</p> <p>Elytral punctures on disc slightly smaller than largest pronotal punctures, becoming finer posteriorly. Intervals not raised, shining, width about 2–3xpd, as are interstices between punctures of a row. Apices in dorsal aspect conjointly rounded, in posterior aspect margins form strong angle with one another.</p> <p>Plaque/intercoxal process ratios (P2/w/l/s) ca. 2/2/7/3. P1 laminate; median carina angulate in profile. P2 l/w ca. 2/1, sides parallel, apex blunt. Plaques located in posterior 1/2 of metaventrite on sides of deep median triangular depression, slightly raised, tapering anteriorly, almost confluent at anterior extreme. AIS flat, width at arcuate posterior margin ca. 2x P2. Protibia (male) slightly arcuate, distal 1/2 slightly thickened; mesotibia slender; metatibia slender, very weakly emarginate on inner surface over distal 3/4. Last sternite with small off-center lobe; last tergite with deep, off-center notch, located opposite sternite lobe.</p> <p>Aedeagus (Fig. 172) main-piece weakly angulate in ventral view, with three short processes on ventral surface; distal piece shorter than main-piece, with (in lateral view) two large, ovoid, rather flat processes, gonopore-bearing flagellum moderately long; parameres inserting at same level on main-piece; left paramere narrow, widest near base, then tapering to sharp tip, long setae in row along ventral margin; right paramere very narrow in basal 1/3, then widened, setae in two groups, some setae quite thick. Female last tergite subtriangular, with three incisions delimiting lobes, medial pair of lobes much larger than lateral pair, setae slender, tapering; subapical, sharp median process, at base of which issue long setae that join together at their tips, forming a "pencil" in dry specimens.</p> <p>Etymology. Named in reference to the three lobes on the ventral face of the aedeagus.</p> <p>Distribution. Currently known from Victoria, New South Wales, and Queensland, in three very disjunct populations (Fig. 256).</p></div> 	https://treatment.plazi.org/id/038187DBFFDCFFAFFF37FAFFFE4C3740	Public Domain	No known copyright restrictions apply.

Intervals not raised, shining, width about 2–3xpd, as are interstices between punctures of a row. Apices in dorsal aspect weakly, separately rounded, in posterior aspect margins form moderately strong angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 4/5/14/4. P1 laminate; median carina angulate in profile. P2 l/w ca. 2/1, sides parallel or weakly convergent, apex blunt. Plaques large, distinctively roundly raised, converging slightly and tapering slightly toward anterior; width of groove separating plaques slightly less than plaque width. AIS flat, width at arcuate posterior margin ca. 2x P2. Protibia (male) gradually weakly widened to about distal 2/3, then tapering to apex; mesotibia slender; metatibia slender, emarginate and flattened on inner surface over middle 1/3 of length, lower margin sharp between emargination and apex. Last sternite symmetrical or nearly so; last tergite with deep, off-center concavity.</p> <p>Aedeagus (Fig. 171) main-piece with lobe on ventral surface and with large distal lobe extending from right to left side; distal piece widest in lateral view, with several lobes, terminating in short gonopore-bearing flagellum; left paramere large, ventral margin with angulate lobe at proximal 1/3, distal 1/2 tapering, with only a few minute setae on ventral margin; right paramere also very asymmetrical, with unusual shape and setae (see figure). Females not yet known.</p> <p>Etymology. Named in reference to the unusual and very dissimilar aedeagal parameres.</p> <p>Distribution.

Recognized by the combination of the large body size (ca. 2.00 mm), the very coarsely and densely punctate pronotum, the coarsely punctate elytra, and, in males, the very large metatibial brush, with undulating tips. H. queenslandica is differentiated from H. pilipes, the males of which also have large metatibial brushes, by the differently shaped and less densely punctate pronotum, and the more regular elytral series near the scutellum (Figs. 177–179). The male genitalia of the two species differ markedly (Figs. 181–184).</p> <p>Description. Size (length/width, mm) holotype: body (length to elytral apices) 2.02/0.81; head 0.32/ 0.42; pronotum 0.48/0.61, PA 0.50, PB 0.57; elytra 1.25/0.81. Dorsum brown to dark brown, head and pronotal disc darker, palpi light brown, not darkened apically.</p> <p>Frons punctures ca. 1.5xef, each with short seta; interstices 0.5–1xpd. Clypeus microreticulate laterally, finely sparsely punctate medially. Mentum microreticulate, dull; postmentum microreticulate. Genae raised, lacking posterior ridge. Pronotum densely coarsely punctate, punctures on disc deep, slightly elongate, ca. 3xpd those of frons, interstices usually less than 1xpd, often narrow walls forming reticulate pattern; PF1, PF2 and PF4 absent; PF3 moderately deep, broad.</p> <p>Elytral punctures slightly larger than largest pronotal punctures. Intervals not raised, shining, width ca. 1xpd or less, as are interstices between punctures of a row. Apices in dorsal aspect conjointly rounded, in posterior aspect margins forming marked angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 2/1/1/3. P1 laminate; median carina angulate in profile. P2 moderately narrow, l/w ca. 2/1, sides slightly diverging toward blunt apex. Plaques small ovals located at posterior margins of deep, median depression. No midlongitudinal carina between mesoventral intercoxal process and plaques. Cuticle asperite under hydrofuge pubescence. AIS flat, width at straight posterior margin 2x P2. Profemur (male) with small tubercle on median surface near basal 1/3; protibia straight, not widened subapically; mesotibia simple; metatibia slender, medial surface very weakly sinuate and with large brush of dense and strong setae over distal 3/4. Abdominal apex asymmetrical.</p> <p>Aedeagus (Fig. 184) main-piece with large, finger-shaped lobe on ventral surface, near base; left paramere very large, with three groups of setae, medioventral part flexible and with minute processes along margin; right paramere lobe-shaped apically, with setae in two groups; distal piece with large, somewhat human headshaped process. Female last tergite with three incisions, delimiting four lobes, setae slender, tapering; gonocoxite as illustrated (Fig. 223).</p> <p>Etymology. Named in reference to the geographical distribution.</p> <p>Distribution. Currently known from many localities in and around the Atherton Tablelands, and two disjunct localities, one each in far northern and far southern Queensland (Fig. 259).</p> <p>Remarks. Females have simple legs; the metaventral depression and small plaques do not differ notably from those of males.</p></div> 	https://treatment.plazi.org/id/038187DBFFD1FFABFF37FF07FE603740	Public Domain	No known copyright restrictions apply.

Watts (45 SAMA).</p> <p>Differential Diagnosis. Differentiated from other large (size ca. 2.05 mm), coarsely punctate species, by the large, smooth and shining interstices on the pronotal disc, the large, narrowly separated plaques, the coarsely punctate elytra with serial punctures not striate-impressed, and the wide explanate elytral margin (Fig. 180). Males have the protibiae weakly bent, and the metatibiae are slender and do not have brushes. The aedeagus is quite distinct (Fig. 185).</p> <p>Description. Size (length/width, mm) holotype: body (length to elytral apices) 2.03/0.88; head 0.31/ 0.47; pronotum 0.50/0.65, PA 0.54, PB 0.59; elytra 1.24/0.88.

Pronotum anteriorly and posteriorly densely coarsely punctate, interstices narrow walls forming reticulate pattern; punctures distinctly sparser on portions of disc, interstices ca. 2–5xpd; punctures much larger than, ca. 5–7xpd, those of frons; PF1 absent; PF2 shallow; PF3 and PF4 moderately deep, broad.</p> <p>Elytral punctures largest near base, about equal size of largest pronotal punctures, becoming smaller posteriorly. Intervals not raised, shining, width on disc ca. 2xpd, as are interstices between punctures of a row. Explanate margin wide. Apices in dorsal aspect weakly separately rounded, in posterior aspect margins forming marked angle with one another.</p> <p>Ratios of P2 width and plaque shape (P2/w/l/s) ca. 2/2/5/0.6. P1 laminate; median carina angulate in profile. P2 moderately wide, l/w ca. 3/2, sides parallel or slightly diverging toward blunt apex. Plaques large, located in posterior 7/10 of metaventrite on sides of median depression, plaques wider posteriorly than anteriorly, separated by less than plaque width. No midlongitudinal carina between mesoventral intercoxal process and plaques. Cuticle non-asperite under hydrofuge pubescence. AIS flat, width at arcuate posterior margin 1.5x P2. Protibia (male) weakly arcuate; mesotibia simple; metatibia very slender, very weakly sinuate, without setal brushes. Abdominal apex asymmetrical.</p> <p>Aedeagus (Fig. 185) main-piece with large, strongly sclerotized process on ventral surface, near base; apical part of main-piece extended in thin, shield-like, arcuate piece that covers part of ventral face; left paramere wide, tapering at distal end, with three groups of setae; right paramere bifid, with three groups of setae. Female last tergite subrectangular, with three incisions, delimiting four lobes, setae slender, tapering.</p> <p>Etymology. Named in reference to the pronotal sculpture: the interstices are generally very smooth, and in places the punctures seem to disappear in places, as if by melting.</p> <p>Distribution. Currently known from eastern Queensland and one interior locality in New South Wales (Fig. 247).</p></div> 	https://treatment.plazi.org/id/038187DBFFD5FFA8FF37FF07FEFB3068	Public Domain	No known copyright restrictions apply.

Recognized from other members of the trapezoidalis Group by the combination of small size (ca. 1.19 mm), the shorter, less widely separated plaques, and the fasciate pronotum. Differs additionally from H. ruinosa by the shorter elytra with more broadly rounded apices, and from H. fundata by the thicker metatibiae (Figs 192, 193, 195). The aedeagus is distinctive (Figs. 196, 197).</p> <p>Description. Size: holotype (length/width, mm): body (length to elytral apices) 1.19/0.54; head 0.20/ 0.31; pronotum 0.32/0.43, PA 0.31, PB 0.43; elytra 0.73/0.54.
