            <p>Diagnosis.</p>
            <p> This is a small-bodied, pallid  Paratachys with thin, translucent cuticle, and an iridescent sheen to the elytra due to the elongate transverse microsculpture; standardized body length 1.9-2.2 mm. The eyes are small but somewhat variable, with from 3-5 ommatidia crossed by a horizontal diameter of the eye, and from 4-6 ommatidia crossed by a vertical diameter (Fig. 9C-F); OR = 1.14-1.19. The elytra are broad, with broadly rounded humeri and broad, nearly truncate apices. The elytral apical recurrent groove is broadly, shallowly impressed. Sutural interneur 1 (i1) of each elytron is well impressed, with the two interneurs bracketing an elevated, callous-like elytral suture, whereas interneurs 2 and 3 are broadly, shallowly impressed to obsolete on the disc, with the outer interneurs absent except for the configuration of interneur 8 (i8) characteristic of  Paratachys (Boyd and Erwin 2016: fig. 1A). </p>
            <p>Description.</p>
            <p> Head narrow, ocular lobes nearly flattened anterad the genae in dorsal view (Fig. 9A); frontal grooves narrow mesad anterior supraorbital seta, broadest between anterior eye margins, and extended to lateral reaches of frontoclypeal suture; antennae moderately elongate, antennomere 9 length twice diameter; mandibles of moderate length, mandibles elongate, distance from dorsal condyle to apex 1.6  × distance from condyle to anterolateral labral margin; labrum transverse, anterior margin evenly emarginate across width, six-setose; penultimate maxillary palpomere broadly spindle-shaped, apical palpomere a narrow spindle (Fig. 9A). Prothorax variably transverse, MPW/PL = 1.33-1.46, with lateral margins distinctly sinuate anterad the acute, projected hind angles, MPW/BPW = 1.18-1.27, the sinuosity of the lateral margins accentuating the cordate appearance more than that represented by measuring pronotal width over the hind angles; pronotal median base depressed, its juncture with disc smooth, basal margin extended medially to form a collar that extends posterad the concave margins posterad the laterobasal depressions; laterobasal depression deepest as a lateral extension of the discal-median base juncture that is directed to the concave basal margin mesad hind angles; pronotal median impression finely depressed, narrow, pronotal disc flattened each side of midline; anterior transverse impression obsolete medially, broadly, shallowly extended laterally to narrowly rounded, moderately projected front angles. Elytra subquadrate, short, humeri broad, EL/MEW = 1.38-1.47; basal groove present laterad position of third interneur on interval distance laterad the parascutellar seta Ed1, groove convexly joined to lateral marginal depression; lateral marginal depression moderately reflexed, of equal breadth from seta Eo3 to subapical sinuation; broader Eo elytral setae elongate, e.g., seta Eo2 length = 0.7 mm, Eo9 length = 0.8 mm (Pahoa Cave, 15-iii-1994, ♂, BPBM). Pterothorax moderately elongate; mesepisternal depression smooth posterad juncture with mesosternum; metepisternum elongate, lateral length 1.6  × maximal width; metathoracic flight wings vestigial, the alae reduced to broad-based stenopterous flaps that extend nearly to posterior margin of first abdominal tergite (Fig. 9G) or to position of seta Eo4 when viewed through elytron, vestiges of radial, medial and cubital veins visible in the wing membrane. Abdomen with one seta each side of apical ventrite in males, two seta each side of ventrite in females. Microsculpture evident on all somites; frons covered with shallow transverse mesh, sculpticells isodiametric and cuticular surface rougher in broad frontal grooves; pronotal disc glossy with elongate transverse sculpticells producing silvery sheen, median base with distinct transverse lines medially, and irregular isodiametric sculpticells laterally; elytra iridescent due to mix of elongate transverse-mesh and transverse-line microsculpture, the transverse lines denser laterally; abdominal ventrites glossy laterally with shallow, swirling elongate-mesh microsculpture. Pelage present on head, prothorax, elytra, pterothorax, abdominal ventrites and legs; pelage on head, pronotal disc, and elytra comprising microsetae separated by distances subequal to setal length (Fig. 9C-F), the microsetae linearly arrayed along elytral interneurs as well as along ommatidial margins of the eyes (Fig. 9B); prosternum and mesosternum covered with sparse pelage medially; pelage of short microsetae present on abdomen in middle of ventrite 2 between metalegs, and progressively more broadly on ventrites 3-6 (absent dorsad arc of metaleg movement); anterior and posterior surface of prothoracic femora sparsely covered with microsetae, anterior (ventral) surfaces of meso- and metathoracic legs more densely covered with elongate microsetae, the setal bases situated more closely than microsetal lengths, trochanters and coxae similarly covered with microsetae. Coloration pale; vertex rufous to rufo-flavous, clypeus rufo-flavous, labrum flavous; antennomeres flavous, outer antennomeres 4-11 with slight smoky cast; maxillary and labial palps flavous; pronotum rufo-flavous; elytra rufo-flavous, elytral lateral marginal depression narrowly flavous medially; elytral epipleuron rufo-flavous, concolorous with thoracic and abdominal ventrites; legs flavous from trochanters outward; pro- and mesocoxae concolorous with outer leg segments, metacoxae rufo-flavous to match thoracic ventrites. Legs with only basal male protarsomere bearing a blunt, antero-apical process. </p>
            <p>Variation.</p>
            <p>A series of five individuals from Kaumana Cave, South Hilo District, include the largest individuals observed for this species. Their standardized body lengths range 2.1-2.2 mm, whereas all other individuals from caves in Hamakua, Puna, and Kau District range 1.9-2.1 mm standardized body length. The Kaumana specimens are also more heavily melanized, though their rufo-brunneous coloration is concolorous with the darkest individuals from the other localities. As neither of these attributes are diagnostic, and variation in male genitalia (below) does not support recognition of the Kaumana Cave individuals as representatives of a distinct species, all individuals described here are considered conspecific.</p>
            <p>Male genitalia.</p>
            <p>Aedeagal median lobe straight to slightly expanded near midlength, dorsal surface straight near midlength, evenly narrowed to rounded tip that is densely covered with sensilla (Fig. 3D-F); flagellar complex broadly hemi-ovoid, with parallel cuticular ridges emanating from densely sclerotized ventrobasal margin; narrow, strap-like right paramere with three setae on narrowly rounded apex; basally broad left paramere elongate, the parallel-sided apical portion with broadly rounded, three-setose apex. There is some variability observable among aedeagal dissections with the dissection of a beetle from Kazumura Cave (Fig. 3D) somewhat broader at midlength, and the aedeagus of a male from Kaumana Cave (Fig. 3F) more gracile than the male from Kau (Fig. 3E). The Kaumana male is larger than the other two (2.2 mm vs. 2.0 mm) consistent with the slightly longer aedeagus observed in that dissection (Fig. 3F vs. Fig. 3D, E). The position of the flagellar complex within the aedeagal shaft is to be discounted, as the entire internal sac is eversible, and its position in repose would vary depending on the level of saccal inversion.</p>
            <p>Female reproductive tract.</p>
            <p>Bursa copulatrix short, broad, with spermathecal duct entering near base of common oviduct (Fig. 10); spermathecal duct very long, by measurement of drawing with mapping opisometer, 1.7 mm (!); spermathecal reservoir indistinctly annulated, at right angle to basal atrium and duct, spermathecal gland duct entering spermatheca near bend; spermathecal gland with narrow duct leading to broader reservoir, the reservoir bearing a small apical assemblage of ductule-bearing secretory cells on a narrow duct; gonocoxa bipartite (Fig. 4C); basal gonocoxite 1 narrow, elongate, a single apical fringe seta near apex of lateral apodeme; apical gonocoxite 2 broadened basally, with lateral extension directed dorsad to ventral surface of coxite bearing two lateral ensiform setae; one dorsal ensiform seta just apicad position of apical lateral ensiform seta; two apical nematiform setae situated in elongate fossa situated halfway between position of dorsal ensiform seta and tightly rounded apex of gonocoxite 2.</p>
            <p>Etymology.</p>
            <p> The species name  Paratachys aaa incorporates the Hawaiian word '  a‘a.‘ā , meaning lava cave (  Nā Puke Wehewehe 'Ōlelo  Hawai‘i 2020). Being a Hawaiian word, the epithet is to be treated as a noun in apposition. </p>
            <p>Distribution and habitat.</p>
            <p> Paratachys aaa has attained a very broad subterranean distribution that includes lava tube caves within Mauna Loa and Kilauea volcanic flows. The species prefers the deep zone of lava tube caves (Howarth 1982), and can thus be considered troglobitic. The type locality, Kazumura Cave northeast of Kilauea (Fig. 11), was formed approximately AD 1445 (Clague et al. 1999), during an eruption of Mauna Loa that lasted approximately 50 years. Pauoa Cave and Burn Cave near the eastern tip of  Hawai‘i Island were formed from Puna volcanics derived from Kilauea eruptions that occurred less than 1000 years ago. Similarly, the caves in Kau accessed from sites in Ocean View Estates near South Point (Fig. 11) were all formed during eruptive episodes of Mauna Loa involving k3 flows that range in age from 750-1500 years old (Trusdell et al. 2005). The northwesterly Bobcat Cave north of the Mauna Loa caldera (Fig. 11) is situated at the margin of a k3 flow overlying an older k2 flow, giving an age of origin for that cave of at most 1500 years ago. And most recently, Kaumana Cave just WSW of Hilo, formed during the 1880-1881 eruption of Mauna Loa. Thus  P. aaa occupies a disparate array of recently formed lava tube caves derived from several eruptive episodes. That these tiny beetles have attained such a broad distributional range among caves of different flows supports  Howarth’s (1972) proposal that Hawaiian cave animals occupy both the larger lava tube caves accessible to humans (and collectors), but also the fractal network of mesocaverns ranging from 0.1-20 cm in diameter that connect those tubes. Add lignified organic layers sandwiched between older and newer flows (Moore et al. 1989) to the mix, and one obtains a complex web of interconnected subterranean voids that supports a variety of microorganisms and the food web built upon them.  Paratachys beetles serve as an apex predator in this system (Howarth 1973), with their active foraging necessarily leading to dispersal among variously available and connected tubes and mesocaverns (Howarth 1983, 1987). Whereas above-ground elevational variation in habitats coupled with geographical variation in rainfall and temperature serve to define geographic distributions, the relatively more homogeneous subterranean voids would allow beetle dispersal among variously connected mesocaverns. Given that their bodies are only 2 mm long, requiring only occasional meals and encounters with conspecifics of the opposite sex to support persistent populations among the variously connected cave systems,  P. aaa have dispersed underground to colonize a broad swath of recently built  Hawai‘i Island. </p>

            <p>Honolulu, Perkins (BPBM, 2).</p>
            <p>Diagnosis.</p>
            <p> This is a small-bodied species, standardized body length 1.9-2.2 mm, with ovoid elytra; EL/MEW = 1.40. The pronotum is transverse, MPW/PL = 1.43-1.48, dimensions shared among Hawaiian  Paratachys only with some individuals of  P. aaa (Fig. 9A), the other small-bodied Hawaiian  Paratachys . The pronotal lateral margins are sinuate basally, and much as in  P. terryli , subparallel just before the nearly right hind angles. However, known specimens of this species are paler than those of  P. terryli (Fig. 1A), with the flavobrunneous head, pronotum and elytra contrasted less with the flavous legs (Fig. 6A). </p>
            <p>Description.</p>
            <p> Head quadrate, ocular lobes little projected, neck broad; frontal grooves bordering convergently convex frons that narrows from anterior supraorbital setae to clypeal margin, the grooves broad and planar laterad convex frons; clypeus convex; eyes small, only slightly convex (Fig. 6A), size ranging from five to seven ommatidia horizontally, six to nine ommatidia vertically; OR 1.16-1.26 for small-eyed vs. large-eyed individuals; labrum quadrate, apical margin straight, six-setose; antennae submoniliform, antennomere 9 length 1.6  × diameter; penultimate maxillary palpomere broadened apically, apical palpomere a narrow spindle (Fig. 6A). Prothorax transverse, MPW/PL = 1.43-1.48, base moderately constricted with lateral margins sinuate anterad right hind angles, MPW/BPW = 1.23-1.29; pronotal median base depressed, surface reticulate due to pebbly microsculpture, unmargined; basal margin beaded each side posterad laterobasal depression which is convex medially, the convexity continuous with disc; pronotal lateral margin beaded, depression mesad bead narrow, but broad enough so that a row of sculpticells can be observed lining the groove; pronotal median impression finely incised, disc convex each side of impression, anterior transverse impression shallow, defining a flat anterior collar medially, groove obsolete laterally near tightly rounded, little protruded front angles. Elytra subovoid, lateral margins evenly convex from humeri to apex, maximum width approximately midlength, HuW/MEW = 0.59; basal groove present laterad seta Ed1 (parascutellar seta), groove subangularly joined to lateral marginal depression; lateral marginal depression moderately reflexed, of equal breadth from seta Eo2 to subapical sinuation; elytral interneurs 1 and 2 deep, smooth on disc, interneur visible only as short segment anterad and obsolete very shallow impression posterad dorsal seta Ed4. Pterothorax moderately elongate, mesepisternal depression smooth posterad juncture with mesosternum, depression deepest and broadest just dorsad mesocoxal cavity; metepisternum broad and short, lateral length 1.3  × maximal width; metathoracic flight wings vestigial in six specimens examined, the broad stub extended to just beyond position of elytral seta Eo3. Abdomen with one seta each side of apical ventrite in males, two seta each side of ventrite in females. Microsculpture evident on all somites; frons covered with evident transversely stretched isodiametric mesh; pronotal disc with elongate transverse mesh, the surface slightly iridescent due to narrow elongate sculpticells, median base opaque due to rough isodiametric sculpticells; elytra subiridescent due to a mix of transverse-mesh and stretched transverse-mesh microsculpture; abdominal ventrites covered with elongate transverse sculpticells, the surface glossy. Pelage present on head, prothorax, elytra, pterothorax, abdominal ventrites and legs; pelage on head and pronotal disc, comprising microsetae separated by distances subequal to setal length, as well as along ommatidial margins of the eyes; microsetae spaced slightly farther apart on elytra, with intersetal distances up to twice microsetal length; anterior (ventral) surfaces of meso- and metathoracic legs bearing pelage of elongate microsetae, the setal bases situated more closely than microsetal lengths, trochanters and coxae similarly covered with microsetae. Coloration ferruginous (Fig. 6A); vertex and frons brunneous, clypeus flavo-brunneous, labrum flavous; antennae flavous; maxillary and labial palps flavous; pronotal disc and elytra flavo-brunneous, elytral lateral marginal depression flavous, elytral epipleuron flavo-brunneous, contrasted to rufo-flavous thoracic and abdominal ventrites; legs flavous from trochanters outward; pro- and mesocoxae concolorous with outer leg segments, metacoxae rufo-flavous to match abdominal ventrites. </p>
            <p>Male genitalia.</p>
            <p>Aedeagal median lobe nearly straight for much of length, slightly, evenly downturned to the broad, shovel-nosed tip (Fig. 3B); flagellar complex hemi-ovoid, the scoop-like apical surface only slightly incurved along ventral margin; strap-like right paramere with three apical setae [left paramere lost from dissection].</p>
            <p>Distribution and habitat.</p>
            <p> The Reverend Thomas Blackburn (1878) noted in his initial description of this species, "Very local, but not rare in some mountainous localities (Blackburn 1878: 158)." Nonetheless, Britton (1948: 240) noted only three specimens in the Blackburn collection (NHMUK), listing them as found at "1500 ft., under bark." The label data do not confirm the elevation or situation, though Blackburn did write "I spent some portion of time (varying from an hour to an occasional twelve hours) in collecting insects on the eastern side of Oahu, as nearly as possible once a fortnight on the average through the six years I spent on the Hawaiian Islands (Blackburn 1885: 204)." Such relatively brief forays would have restricted his collecting to the southern Koolau Range, encompassing the hills above Honolulu including Round Top, Tantalus, or perhaps Lanihuli or Konahuanui on a long day. These areas were considerably more accessible at that time due to the absence of human residential developments and the depredations of goats on the native vegetation that opened the forest (Liebherr and Polhemus 1997). R.C.L. Perkins collected two specimens at Honolulu in the early 20th Century, also very likely found on or near Tantalus, as he frequented that site in a continuing search for rarely collected insects (Perkins 1906), correctly predicting the extinction of many species found only there (e.g., Liebherr 2009). No specimens have been collected near  “Honolulu” since Perkins, and we can surmise that this species is extinct. </p>
            <p>Nomenclatural notes.</p>
            <p> Erwin (1974b) clarified generic concepts of New World tachyines, assigning species to proper genera, and designating lectotypes to stabilize nomenclature for type series of species deposited among multiple worldwide institutions. He assigned  Tachys arcanicola Blackburn to  Paratachys Casey and wrote "Lectotype, male, here designated, in NHMUK (Erwin 1974b: 139)." Previously, Britton (1948: 240) cited three NHMUK Blackburn specimens from Oahu, all males, as representatives of  T. arcanicola , although he did not select a lectotype from among them. Later during his 1948-1972 tenure as an honorary associate of The Natural History Museum, London (Upton 2004), E.C. Zimmerman dissected the male labelled with the round, red-margined  “Type” label during his researches on Hawaiian  Carabidae , with the dissection described above. The NHMUK round red-margined  “Type” labels were used variously to designate specimens prior to World War II, and then all beetle specimens were dispersed to safe haven in Wales, Scotland, and to the west of London prior to the Nazi Blitz of 1940-1941 (Jones 2013; M.E. Bacchus, pers. comm.). Thus, the labels themselves do not hold nomenclatural value. In 1998, the author examined the three male specimens reported in Britton (1948), and labelled the specimen dissected by Zimmerman and bearing the red-margined  “Type” label as lectotype. No other specimen of  T. arcanicola bearing an Erwin lectotype label was found among NHMUK material at that time. This absence was affirmed by a recent search of the entire NHMUK tachyine holdings (B. Garner, pers. comm.), again resulting in no Erwin-labelled lectotype specimen for this taxon, though Erwin labels were found on various other specimens representing Neotropical taxa for which lectotypes were designated in Erwin (1974b). More broadly, no Erwin lectotype-labelled specimen was found by the author in the H. W. Bates collection in the MNHN, Paris, although a single specimen in the Bates holdings of the  Oberthür Collection is accounted for above as a Parisian paralectotype. Because all three syntype specimens of this species in the British Museum are males, all three were identically accounted for both in Britton (1948) and during the  author’s 1998 visit, and no other Erwin-labelled lectotype specimen exists in Bates material in Paris, it is unavoidably concluded that Erwin never labelled a specimen as lectotype for this taxon. Because his published designation specified a male specimen, but there are three male syntype specimens in the NHMUK, Erwin failed to designate a "single name-bearing type specimen" as lectotype (I.C.Z.N. 1999, glossary). As "A lectotype may be designated from syntypes to become the unique bearer of the name of a nominal species-group taxon (I.C.Z.N. 1999, Article 74.1)", his published statement is invalid. In the extremely unlikely circumstance that an Erwin-labelled lectotype specimen would surface from some other venue, unlikely because it cannot be one of the three NHMUK specimens cited by Britton (1948), and its very existence would violate  Erwin’s (1974b) statement that his lectotype was designated from a NHMUK male specimen, then the lectotype presently designated above would become invalid. The present lectotype designation is undertaken to eliminate ambiguity with regard to how this species is to be tied to zoological nomenclature, with future rediscovery of an Erwin-labelled lectotype specimen of a Blackburn syntype the only means to validate  Erwin’s (1974b) published action. </p>

        <div>
            <p> Paratachys Casey, 1918</p>
            <p> Paratachys Casey, 1918: 174 (type species  Paratachys austinicus Casey by original designation); Erwin 1974b: 128; Boyd and Erwin 2016: 95, 110. </p>
            <p> Eotachys Jeannel, 1941: 426 (type species  Tachys bistriatus Duftschmid by original designation). Synonymy by Erwin (1971: 236). </p>
            <p> Macrotachys Kult, 1961: 2 [junior homonym of  Macrotachys Uéno , 1953: 42] (type species  Bembidium fulvicolle Dejean by original designation). Synonymy under  Eotachys by Lindroth (1966: 431). </p>
            <p>Diagnosis.</p>
            <p>These beetles can be diagnosed by: deep paramedial pits of the mentum (Figs 1B, 8B, 9B); head with two supraorbital setae each side (Figs 1C, D, 8C, D, 9D, F); pronotum moderately cordate to nearly quadrate, MPW/BPW = 1.17-1.34; anterior terminus of elytral apical recurrent groove (ARG) slightly to distinctly hooked and situated laterad position of interneur 4, ARG laterally encompassing the fourth discal seta Ed5-6 (Figs 1A, 6, 8A, 9A); elytral setation including ombilicate setae in an anterior series Eo1-4, a posterior series Eo5-8 associated with posterior sulcus, and Eo9 just mesad ARG, plus dorsal setae Ed1, Ed5-6, Ed7, and Ed8; interneur 8 with posterior sulcus in apical half of elytron, the anterior portion of sulcus directed away from the elytral lateral margin and encompassing setae Eo5-6, and setae Eo7 and Eo8 situated toward the elytral apex between i8 and the apical recurrent groove; and protibia expanded laterally at apical 1/4 of length (Fig. 1A), the associated latero-apical notch lined basally with a transverse row of closely spaced setae (e.g., Maddison et al. 2019: fig. 7A).</p>
            <p> For Hawaiian taxa the position of the dorsal seta within the arcuate ARG differs from that in Neotropical  Paratachys (Boyd and Erwin 2016) by being situated near the middle of the arc (Figs 1A, 8A, 9A), not further forward near the apical hooked terminus of the groove (e.g., Boyd and Erwin 2016: fig. 1A, C). This suggests that the seta within the arc may represent Ed6 in Hawaiian  Paratachys , vs. Ed5 in Neotropical taxa (Boyd and Erwin 2016: fig. 1A). An anterior placement of the seta mesad the hooked terminus of the ARG is also observed in Asian  Paratachys (Andrewes 1925: plate 3; Tanaka 1956: fig. 1; Tanaka 1960: fig. 1; Habu 1977: fig. 1; Baehr 2017: figs 29-34), the Palaearctic  P. bistriatus (Duftschmid) (Jeannel 1941: fig. 168A) as well as numerous other Palaearctic species (Coulon 2004: figs 2-4), various Madagascan species (Jeannel 1946: fig. 154), Canary Island species (Machado 1992: fig. 73C, D), and Nearctic taxa such as  P. proximus (Say) and  P. scitulus (LeConte) (Lindroth 1966: figs 209f, 222). </p>
            <p> Finally, all Hawaiian species have the cuticular surfaces of head, prothorax, elytra, meso- and metathoracic sternites, abdominal ventrites, and femora covered with a pelage of fine microsetae (Figs 1C-I, 8C, D, 9C-F). These microsetae occur in line with the elytral interneurs, and on the compound eyes are set along the ommatidial margins (Figs 1B, 8B, 9B). Again, this configuration differs from that of Nearctic taxa such as  P. austinicus Casey,  P. proximus , and  P. scitulus (CUIC), in which only the meso- and metathoracic femora bear such a pelage and all other body surfaces are glabrous excepting macrosetae. It should be noted that some  Tachys spp. also have the ventral surface of the meso- and metathoracic femora covered with a sparse pelage; e.g.,  T. litoralis Casey,  T. mordax LeConte, and  T. vittiger LeConte.  Setitachys macrops Baehr (2016) of northern Australia also bears a setose pelage over the body, but this species differs dramatically from the Hawaiian  Paratachys in mandibular length, pronotal shape, elytral striation, and aedeagal configuration, suggesting an independent origin for the pelage in the two lineages. Species of the  Lymnastis Motschulsky-  Micratopus Casey lineage (Maddison et al. 2019) are also characterized by such a full-body pelage (Baehr 2016). </p>
            <p>Identification and generic placement.</p>
            <p> Boyd and  Erwin’s (2016) key to New World  Tachyina supports generic assignment of Hawaiian  Paratachys through use of the characters that diagnose the genus worldwide.  Andrewes’ (1925) key to Oriental  Tachys Dejean sensu lato is based on a similar though simplified set of characters that assigns Hawaiian  Paratachys species to his " triangularis " group. Finally, Britton (1948) could be used firstly to generically determine Hawaiian  Paratachys as  Tachys , and then as the only previously described species,  Paratachys arcanicola (Blackburn) (Britton 1948: 238), although  Britton’s keys do not utilize diagnostic characters (Boyd and Erwin 2016) that underlie taxonomic definition of  Paratachys . </p>
            <p> Coulon (2004) distinguished European species of  Eotachys Jeannel from those of  Paratachys based on the complete eighth elytral interneur of the Nearctic  P. austinicus Casey, type species of  Paratachys , vs. an interrupted eighth interneur in the European  Tachys bistriatus Duftschmid, type species of  Eotachys . However, as the European  Tachys bistriatus is nested within a clade of New World  Paratachys spp., with the Hawaiian  Paratachys terryli (reported as  Paratachys sp. "U.S.A.: Hawaii") placed as their respective adelphotaxon in a comprehensive molecular phylogenetic analysis (Maddison et al. 2019, fig. 12), the synonymy of  Eotachys under  Paratachys reported first by Erwin (1971) is corroborated, and herein accepted. </p>

            <p> Paratachys haleakalae sp. nov. Figures 3C, 4B, 7, 8 </p>
            <p>Type material.</p>
            <p>Holotype female (CUIC; undissected, point-mounted): HI:Maui Haleakala N.P. / Kipahulu Vy. Central / Pali Tr. 910 m el. / 30-IV-1991 under logs // J.K. Liebherr / A.C. Medeiros / Jr. collectors // HOLOTYPE ♀ / Paratachys / haleakalae / J. K. Liebherr 2020.</p>
            <p>Paratypes. Three specimens with same collection data as holotype (CUIC, 3; dissected male allotypic paratype and two female paratypes, one lacking left elytron; Fig. 8E).</p>
            <p>Diagnosis.</p>
            <p> Immediately diagnosable among Hawaiian  Paratachys by the narrow, more quadrate pronotum that is little constricted basally (Fig. 8A); MPW/PL = 1.29-1.36 and MPW/BPW = 1.21-1.26. The pronotal basal margin is shallowly sinuate just inside the hind angles, with the median basal margin extended posteriorly as a narrow collar. Elytral interneurs 1 and 2 are deep and broad on the disc, and interneur 3 is evident posterad dorsal seta Ed4. The eyes are somewhat variable, but always small and little convex; 4-7 ommatidia crossed by a horizontal diameter of the eye, and 6-9 ommatidia crossed by a vertical diameter (Fig. 8C, D). The head, pronotum and elytra are a rich rufobrunneous, distinctly contrasted to the flavous antennae and legs. Standardized body length 2.3-2.4 mm. </p>

Pterothorax elongate, mesepisternal depression smooth posterad juncture with mesosternum; metepisternum elongate, lateral length 1.9  × maximal width; metathoracic flight wings vestigial, the alae reduced to stenopterous flaps that extend to posterior margin of first abdominal tergite (Fig. 8E), vestiges of radial and medial veins visible in the wing membrane. Abdomen with one seta each side of apical ventrite in male, two seta each side of ventrite in females. Microsculpture evident on all somites; frons covered with evident transverse mesh, sculpticells more isodiametric in broad frontal grooves; pronotum slightly iridescent due to elongate transverse sculpticells, median base with isodiametric sculpticells in wrinkles, elevated ridges glossy; elytra subiridescent due to a mix of elongate transverse-mesh and transverse-line microsculpture, the transverse lines denser laterally; abdominal ventrites iridescent, covered with swirling, elongate transverse sculpticells. Pelage present on head, prothorax, elytra, pterothorax, abdominal ventrites and legs; pelage on head and pronotal disc comprising microsetae separated by distances subequal to setal length (Fig. 8C, D), as well as along ommatidial margins of the eyes (Fig. 8B); microsetae spaced slightly farther apart on elytra, with intersetal distances up to twice microsetal length; prosternum and mesosternum covered with sparse pelage medially; pelage on abdomen present at middle of ventrite 2 between metalegs, and progressively more broadly on ventrites 3-6 (absent dorsad arc of metaleg movement); anterior surface of prothoracic femora sparsely covered with microsetae, anterior (ventral) surfaces of meso- and metathoracic legs more densely covered with elongate microsetae, the setal bases situated more closely than microsetal length, trochanters and coxae similarly covered with microsetae.

            <p>Female reproductive tract.</p>
            <p>Bursa copulatrix short, broad, with spermathecal duct basal terminus at juncture of bursa and common oviduct (as in Fig. 10); spermathecal duct elongate, at least 0.64 mm (duct broken in single attempted dissection); gonocoxa bipartite; basal gonocoxite 1 elongate, with a single apical fringe seta near apex of lateral apodeme (Fig. 4B); apical gonocoxite 2 broadened basally, with lateral extension directed dorsad to ventral surface of coxite bearing the two lateral ensiform setae; one dorsal ensiform seta situated halfway between position of apical lateral seta and narrow, pointed apex; two apical nematiform setae situated in elongate fossa near apex of gonocoxite.</p>
            <p>Etymology.</p>
            <p> The species epithet  Paratachys haleakalae represents the first declension genitive form indicating the species is distributed on  Haleakalā Volcano, East Maui. </p>
            <p>Distribution and habitat.</p>
            <p> The type locality of  P. haleakalae is Dogleg Camp, so named because the site is near a prominence of the upper shelf of Kipahulu Valley at 3000 ft. (910 m) elevation, 20°42.03'N, 156°04.93'W, that overlooks the lower part of the valley drained by Palikea Stream (Fig. 7). The forest at Dogleg Camp is montane wet forest dominated by large  Acacia koa A. Gray (  Fabaceae ), with lower stature  Cheirodendron trigynum (Gaud.) A. Heller, and woody herbaceous  Broussasia arguta Gaud. (  Hydrangeaceae ),  Clermontia Gaud. (  Campanulaceae ),  Hedyotis L. (  Rubiaceae ),  Pelea A. Gray (  Rutaceae ), and  Scaevola L. (  Goodeniaceae ) also present. The climbing vine-like  Freycinetia arborea Gaud. (  Pandanaceae ) is also quite common. That said, the type series of  P. haleakalae was collected from under a  Acacia koa log round serving as a step on the pathway to the camp privy. The beetles were in voids amongst plant roots under the log round. This is perhaps the  author’s sole datum discounting the Darlington Rule: "Never roll rocks in the tropics (P.J. Darlington, Jr., pers. comm.)." </p>

Coloration ferruginous (Fig. 6B); vertex and frons brunneous, clypeus flavo-brunneous, labrum, mandibles and palpomeres flavous; antennae flavous; pronotal disc and elytra flavo-brunneous, elytral lateral marginal depression slightly paler, elytral epipleuron flavo-brunneous, contrasted to rufo-flavous thoracic and abdominal ventrites; legs flavous from trochanters outward; pro- and mesocoxae concolorous with outer leg segments. </p>
            <p>Female reproductive tract.</p>
            <p>The single historically collected holotype specimen was not dissected.</p>
            <p>Etymology.</p>
            <p> This species is named to honor its collector, R.C.L. Perkins, who as a new graduate of Oxford University was sent in 1891 to  Hawai‘i , by the British Association for the Advancement of Science to collect zoological specimens in support of the 'Fauna  Hawaiiensis’ project (Sharp 1913; Manning 1986). Dr. Perkins stayed on after his initial Hawaiian surveys, during which the holotype of this species was collected, to serve in the Territory of  Hawaii’s Agricultural Department and then as Director of the Experiment Station of the Hawaiian Sugar  Planters’ Association (Scott and Benson 1955; Scott 1956). Throughout his scientific career, Perkins conducted systematic research on a wide variety of insect taxa (Evenhuis 2005) as well as the control of pestiferous insects and weeds using introduced natural enemies (Perkins 1897, 1923; Perkins and Swezey 1924). </p>
            <p>Distribution and habitat.</p>
            <p> The lone specimen representing this species is labelled as  Perkins’ lot 170, Kaunakakai, July 1893, sea level.  Perkins’ Moloka‘i July collecting commenced on 9 July, however much of his time was spent high in the forests (Evenhuis 2007). He walked to the coast on 17 July, arriving at Kaunakakai in the afternoon. He spent the next two days hunting shorebirds and coots, and on the 20th "Walked along the coast to Kaluaaha supposed to be about 16 miles E. ... I stayed some time at Kawela ... (Evenhuis 2007: 262)." After his midday stop at the base of Kawela Gulch he encountered a "heavy shower" and "finishing of the school term" at Kalua 'aha. The next day he walked back to Kaunakakai, and on the 21st came down with a sore throat, which progressed to what he self-diagnosed as "the  ‘grippe’ or influenza (Evenhuis 2007: 163)." He returned to the mountains on 24 July, closing the temporal window during which  P. perkinsi could have been collected. Thus, a best guess concerning the collecting locality of the lone  Paratachys perkinsi is in the streambed of Kawela Gulch near the coast on 20 July (Fig. 7). Such a situation would be similar to the streamside situations frequented by  P. terryli of Kauai, although at considerably lower elevation. Kawela Stream at higher elevations houses several flightless riparian species, including the nabid bug,  Nabis gagneorum Polhemus (1999), and the very large-bodied, vestigially winged carabid beetle,  Blackburnia polhemusi Liebherr (Liebherr and Zimmerman 2000). The riparian habits of both of these species are unusual among their respective radiations, pointing to Kawela Gulch as a persistent and stable water source able to support populations of flightless insects. </p>

            <p>Diagnosis.</p>
            <p> This species shares elongate elytra (EL/MEW = 1.45-1.50; Fig. 1A) with  P. perkinsi (Fig. 6B) and  P. haleakalae (Fig. 8A), but the pronotal lateral margins are less sinuate than those of  P. perkinsi , and more sinuate than those of  P. haleakalae . The apical recurrent elytral groove is distinctly and narrowly impressed, with a well-defined, medially curved anterior terminus, and the elytra are truncate apically as evidenced by the nearly straight apical groove connecting the sutural and the recurrent grooves. As with  P. haleakalae , elytral interneurs 1-3 are clearly impressed on the disc, but interneur 4 is traceable though discontinuous in this species, opposed to obsolete as in  P. haleakalae . Standardized body length is 2.2-2.4 mm. </p>
            <p>Description.</p>
            <p> Head robust, frontal grooves shallow, convergent posterad clypeus, divergent to frontal lateral margin at frontoclypeal suture just anterad antennal articulation, broadly, slightly elevated laterally to position of anterior supraorbital seta; eyes variable, from large, macrophthalmic with 12 ommatidia crossed by horizontal diameter and 15 ommatidia crossed by vertical diameter (Fig. 1C), to very small with dimensions of four ommatidia by five ommatidia horizontally and vertically (Fig. 1I), with continuous variation of dimensions between those extremes (Fig. 1D-H; see Variation section below); antennae moderately elongate, antennomere 9 ovoid, length twice diameter; labral anterior margin undulated, slightly incurved each side of midline, six-setose; penultimate maxillary palpomere broadened apically, apical palpomere a narrow spindle (Fig. 1B, E). Prothorax transverse, MPW/PL = 1.35-1.41, base moderately constricted with lateral margins sinuate anterad right hind angles, MPW/BPW = 1.21-1.34; pronotal median base depressed, longitudinally wrinkled, unmargined; basal margin beaded each side posterad laterobasal depression which is deepest just laterad broadly triangular median base; pronotal lateral margin beaded, depression mesad bead narrow but broad enough so that a row of sculpticells can be observed lining the groove; pronotal median impression finely incised, disc flat, anterior transverse impression obsolete, not evident medially or toward slightly protruded, narrowly rounded front angles. Elytra subquadrate, lateral margins evenly convex from humeri to apex, maximum width approximately midlength; basal groove present laterad position of fifth interneur, groove convexly joined to lateral marginal depression; lateral marginal depression reflexed, of equal breadth from seta Eo2 to subapical sinuation. Pterothorax elongate, mesepisternal depression smooth posterad juncture with mesosternum, depression deepest and broadest just dorsad mesocoxal cavity; metepisternum elongate, lateral length twice maximal width; metathoracic flight wings polymorphic, 18 of 19 individuals in type series with wings reduced to a vestigial stub (Fig. 1J), and 1 female with fully developed flight wings (Fig. 2A), with length of alar surface 2.3  × breadth, and radial, medial, cubital and anal veins and an oblongum cell present. Abdomen with one seta each side of apical ventrite in males, two seta each side of ventrite in females. Microsculpture evident on all somites; frons covered with evident transverse mesh, sculpticells more isodiametric posteriorly on vertex; pronotum slightly iridescent due to elongate transverse sculpticells, median base and laterobasal depressions more opaque due to reticulated isodiametric microsculpture; elytra subiridescent due to a mix of elongate transverse-mesh and transverse-line microsculpture, the transverse lines denser laterally; elytral apex more opaque due to slightly raised isodiametric sculpticells between sutural interneur and apical recurrent groove; abdominal ventrites covered with elongate transverse sculpticells, the surface glossy to subiridescent. Pelage present on head, prothorax, elytra, pterothorax, abdominal ventrites and legs; pelage on head and pronotal disc, comprising microsetae separated by distances subequal to setal length (Fig. 1F, G), as well as along ommatidial margins of the eyes (Fig. 1B); microsetae spaced slightly farther apart on elytra, with intersetal distances up to twice microsetal length; prosternum and mesosternum medially covered with microsetae as densely distributed as on frons and pronotum; pelage on abdomen present at middle of ventrite 2 between metalegs, and progressively more broadly on ventrites 3-6 (absent dorsad arc of metaleg movement); anterior surfaces of pro-, meso-, and metathoracic legs bearing pelage of elongate microsetae, the setal bases situated more closely than microsetal lengths, trochanters and coxae similarly covered with microsetae. Coloration moderately dark; vertex and frons dark brunneous to piceous, clypeus flavobrunneous, labrum flavous; basal two antennomeres flavous, outer antennomeres progressively darker, apical segments brunneous; maxillary and labial palps flavous; pronotal disc and elytra brunneous, elytral base near scutellum paler, rufobrunneous, elytral lateral marginal depression flavobrunneous, elytral epipleuron rufoflavous, contrasted to rufobrunneous thoracic ventrites; legs flavous from trochanters outward; pro- and mesocoxae concolorous with outer leg segments, metacoxae more brunneous laterally to match the dark brunneous ventrites. Legs with basal male protarsomere alone bearing a blunt, antero-apical process. </p>
            <p>Variation.</p>
            <p> The compound eyes vary dramatically in this species, from fully macrophthalmic (Fig. 1C), to microphthalmic (Fig. 1I); OR ranging 1.15-1.35 for smallest- to largest-eyed individuals. That these differences reflect infraspecific variation is supported by presence of the extremes plus a variety of intermediate configurations (Fig. 1D-H) among specimens collected microsympatrically within the identical collecting series (Fig. 1C-I).  Paratachys terryli is also polymorphic for flight-wing development, with a single macrophthalmic female specimen (Fig. 1C) bearing fully developed flight wings (Fig. 2A). The wings of this female are of dimensions similar to those of fully flighted individuals of  Tachys oahuensis (Fig. 2B) that were collected in ultraviolet light traps. Venation differs among the two compared species, with the wing of the female  P. terryli exhibiting the oblongum cell but not the basal stem of the radius posterior (  Kukalová-Peck and Lawrence 1993), whereas the wing of  T. oahuensis lacks the oblongum but retains the radius posterior. Both wings are folded reflexively under the elytra, with the spring-like wing margin apicad the radial cell flipping the wing open when the wing is deployed. The various brachypterous individuals exhibit a variety of eye configurations. Wing configuration is not associated with morphological variation in elytral dimensions based on comparison of four simultaneously collected females (Namolokama Mountain, 23-v-2005, lot 1) with HuW/MEW for the macropterous female = 0.57, and HuW/MEW for the three brachypterous females = 0.57-0.58. </p>
            <p>Male genitalia.</p>
            <p>Aedeagal median lobe porrect, parallel-sided with an evenly rounded apex (Fig. 3A); flagellar complex elongate, with a sinuously scooped apical margin; right paramere narrow, strap-like with three apical setae; left paramere broad, elongate, with a broadly rounded apex and three apical setae.</p>
            <p>Female reproductive tract.</p>
            <p>Bursa copulatrix short, broad (as in Fig. 10), spermathecal duct narrow and extremely elongate, at least 0.57 mm long in single dissection attempt; gonocoxa bipartite, basal gonocoxite 1 narrow, elongate, with a broad, lateral sclerotized apodeme and a single apical fringe seta situated near apex of apodeme (Fig. 4A); apical gonocoxite falcate, broadly expanded laterally at base, apex finely acuminate; two peg-like lateral ensiform setae along mid-ventral line, and one like-sized dorsal ensiform seta dorsad the apical lateral seta; two apical nematiform setae in an elongate fossa situated at approximately 2/3 length of the apical gonocoxite.</p>
            <p>Etymology.</p>
            <p> This species honors Terry L. Erwin by combining his first name and middle initial to form the genitive patronym  Paratachys terryli . This construction follows that of  Bembidion carlhi Erwin and Kavanaugh (1981), a species that honors Carl H. Lindroth whose 'Carabid Beetles of Canada and  Alaska’ monograph (Lindroth 1969 et. seq.) revolutionized the study of North American  Carabidae . Analogous to  B. carlhi , this epithet recognizes  Terry’s immense impact on the study of Neotropical  Carabidae as well as tropical biodiversity writ large. </p>
            <p>Distribution and habitat.</p>
            <p> This species is known from the Alakai Swamp west of the Wainiha River, and from Namolokama Mountain, a ridge to the east bordered by the Lumahei and Hanalei Rivers (Fig. 5). It has been most commonly collected in leaf and moss litter taken from low stature Ohia lehua (  Metrosideros polymorpha Gaud.;  Myrtaceae ) forest. At a site at 1340 m elevation on Namolokama, one sample (21-v-2005, lot 1) sifted and subsequently hand-picked contained five  Paratachys terryli in company with two  Bembidion admirandum (Sharp), two  B. corticarium (Sharp), and two  Blackburnia kauaiensis (Sharp). A second sample from the same site (21-v-2005, lot 8) was double-boiled on a stove, resulting in discovery of one  B. admirandum , eight  B. corticarium , and one  P. terryli . A third Namolokama sift sample from 1305 m elevation (23-v-2005, lot 1) contained seven  P. terryli in company with specimens of three species of  Blackburnia ; two  B. posticata (Sharp), and one each  B. bryophila Liebherr and  B. kauaiensis (Sharp). Most other collections of  P. terryli represent singletons most often collected in company with  Bembidion spp., including: 16-V-1991 lot 5 from a rocky streambed also including five  B. ignicola (Blackburn); 17-v-2005 lot 4 from Berlese extraction of leaf litter siftate along with two  B. admirandum and three  B. munroi ; and 17-v-2005 lot 9, double boiled from leaf litter siftate along with six  B. admirandum and two  Bl. posticata . Thus, it would appear from presently available evidence that  P. terryli occurs in microhabitats most often also occupied by  Bembidion beetles, either along streams, or in deep terrestrial leaf litter in montane wet ohia forest. </p>
