039A2D1C0A3CDF46FF29D2C55BFBFCDC.taxon	discussion	Remarks. Grouvelle described A. bimaculatus in 1912 from Port Bowen, Queensland (Fig. 5 B), but did not designate a holotype. Two Grouvelle’s syntypes, mounted on a single card, are deposited in the Natural History Museum in London. The left specimen is here designated as the lectotype. Lea (1921 b) ignored Grouvelle’s description and described the same species under the same name from the same locality (Fig. 5 C), making Lea’s species both a homonym and a synonym. In the South Australian Museum collection (SAMA), two specimens labelled “ TYPE ” are mounted on a single card. The left specimen, with “ TY ” handwritten beneath it, is here designated as the lectotype. The cotype of A. bimaculatus Lea, form the Queensland Museum (QMB) (examined), is not A. bimaculatus but represents another species, A. potamophilus. Subsequently, John (1941) also ignored both Grouvelle’s (1912) and Lea’s (1921 b) publications and described another species under the name A. austerus from Rockhampton, around 500 km south of Bowen (Fig. 6 D). Later, he (John 1954) recognized Grouvelle’s description and synonymized A. austerus John with A. bimaculatus Grouvelle. In the original publication, John (1941) did not designate a holotype but mentioned that the type series was deposited in museums in Hamburg, Berlin-Dahlem, and Budapest. The majority of the Hamburg collection was lost during WWII, and these materials are no longer present in the collection (D. Żyła, pers. comm.). Specimens that were originally deposited in the Deutsches Entomologisches Institute in Berlin-Dahlem are now housed in the Senckenberg Deutsches Entomologisches Institut in Müncheberg (SDEI), and two specimens of A. austerus John are deposited there. The first specimen (mounted to a card with dissected male genitalia) with the label data cited above is here designated as the lectotype. In the same publication (John 1941), John also described another species under the name Aphanocephalus perlucidus, based on a single specimen from Brisbane. Although the holotype of that species is missing from the collection of the SDEI (K. Weissing, pers. comm.), John illustrated the male genitalia of the holotype in his subsequent publication (John 1967 b). These genitalia agree in all details with the genitalia of A. bimaculatus Grouvelle, which makes A. perlucidus John a synonym as well. Lectotypes of A. bimaculatus Grouvelle, A. bimaculatus Lea, and A. austerus John are here designated to clarify the taxonomic status of the respective species.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A3BDF47FF29D4305C74FDF1.taxon	diagnosis	Diagnosis. Very distinctive species with elongate oval body outline, entirely black elytra with two red-orange round maculae on each elytron. It co-occurs with, and is most similar to A. leai, but A. blackburni is larger and it is clothed with short, appressed pubescence on pronotum and elytra (Figs 6 B, 7 C, D), while A. leai is more rounded, smaller and with much denser, longer and more erected pubescence (Fig. 8 B). Moreover, anterior elytral macula in A. blackburni is sub-oval, while in A. leai it is angulate. Male genitalia of A. blackburni are very unique (Figs 10 D – E).	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A3BDF47FF29D4305C74FDF1.taxon	discussion	Remarks. Lea (1921 a) described A. quadrimaculatus unaware that Matthews (1887: 114) had already used that name for his species described from Penang (Malaysia), making Lea’s name a junior homonym. Aphanocephalus blackburni is here proposed as a replacement name. In the SAMA collection, two specimens are mounted on the same card with the label “ TYPE ”.

039A2D1C0A3ADF59FF29D5E45D7BFED1.taxon	etymology	Etymology. The specific name “ calderi ” is a patronym in honor of Andrew Calder, an Australian entomologist, and the collector of the type series.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae). Zootaxa 5632 (3): 401-440, DOI: 10.11646/zootaxa.5632.3.1, URL: https://doi.org/10.11646/zootaxa.5632.3.1
039A2D1C0A3ADF59FF29D5E45D7BFED1.taxon	diagnosis	Diagnosis. Aphanocephalus calderi, with its rufous-orange dorsal body coloration, is most similar to A. potamophilus. However, it can be distinguished from the latter by the very narrow lateral margins of the elytra, whereas in A. potamophilus, they are distinctly explanate. Moreover, A. calderi has single-sized punctae on the pronotum, while in A. potamophilus, the punctation is double, with larger and coarser punctae in the posterior pronotal corners. The central area of the elytra in A. calderi is covered with small punctae of a single size, whereas in A. potamophilus, there are two intermixed sizes of punctae. The male genitalia of A. calderi are also most similar to those of A. potamophilus, but the apex of the tegmen is rounded in A. calderi (Fig. 10 I) and truncate in the latter (Fig. 13 F). In lateral view, the penis of A. calderi has a more distinctly rounded inner margin (Fig. 10 G) than in A. potamophilus (Fig. 13 D).	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A27DF5CFF29D7F05E59FB25.taxon	diagnosis	Diagnosis. Aphanocephalus kukuyalanji is a distinctive, small species with a sub-rounded, spherical body shape. The body outline often appears polygonal due to glandular pores that slightly protrude from the body outline. The dorsal surface of both the pronotum and elytra is entirely rufous-orange, with a single oval or slightly transverse brown to dark brown lateral macula on each elytron. In some specimens, the pronotum has a dark discal area, sometimes divided into two smaller, separate maculae. The body shape and coloration are unique among Australian species of Aphanocephalus. A similar body shape and size is found in A. queenslandicus, which may co-occur with A. kukuyalanji. However, A. queenslandicus is entirely dark brown, usually with paler maculae on each elytron and a row of large pseudopores along the lateral margins of the elytra, which are absent in A. kukuyalanji. Additionally, the punctures on the elytra of A. kukuyalanji are small and shallow, while those of A. queenslandicus are distinctly larger and coarser.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A20DF5EFF29D3595DECFBDD.taxon	diagnosis	Diagnosis. Aphanocephalus leai is a very distinctive species and can be easily separated from Australian congeners by small, oval body, dark brown to black dorsal coloration, pronotum with yellowish-rufous antero-lateral margins, and elytra with two red-orange maculae (Fig. 8 A), and relatively long pubescence longer and denser on pronotum than on elytra (Fig. 8 B). It is most similar to A. blackburni but that species is covered with very short, appressed pubescence (Figs 7 C, D), and its anterior elytral macula is sub-oval, while in A. leai it is angulate. It is also similar to A. hackeri however that species has three elytral maculae on each elytron (Fig. 7 G).	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A20DF5EFF29D3595DECFBDD.taxon	discussion	Remarks. Lea (1921 b) described A. quadrinotatus, unaware that Grouvelle (1912: 206) had already used that name for a species from the Kai Islands (Moluccas). Consequently, Lea’s name is a junior homonym. Aphanocephalus leai is here proposed as a replacement name. In SAMA collection, there are two specimens mounted on the same card with the label “ TYPE ”. The left specimen, with “ TY ” handwritten beneath it, is here designated as the lectotype to fix the taxonomic status of this species. Two specimens labelled “ co-type ” from the SAMA collection, bearing the Lea’s number 20222, are not listed in the original publication and here treated as non-type material. Lea (1921 b) mentioned that he examined specimens with fused (or partially fused) maculae on elytra, so they formed a single more or less s-shaped macula on each elytron.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A22DF51FF29D4305E87FDD5.taxon	etymology	Etymology. Specific epithet derived from the Latin adjective “ occidentalis ” meaning Western.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A22DF51FF29D4305E87FDD5.taxon	diagnosis	Diagnosis. Aphanocephalus occidentalis, with its almost entirely brown dorsal coloration (except for the paler lateral margins of the pronotum and humeral areas of the elytra) and rounded, spherical body shape, is quite unique among Australian species. It is also a distinctive species inhabiting Western Australia. Only in the very northeastern part of Western Australia might it co-occur with A. potamophilus. However, A. potamophilus differs in having a more elongated body outline and a less spherical shape. Its dorsal coloration is predominantly rufous, sometimes featuring a brown sutural line extending into a central elytral rhomboid macula. Additionally, A. occidentalis displays nearly uniform punctation on the pronotum, while A. potamophilus has double punctation, with larger and coarser punctae in the posterior corners of the pronotum. The male genitalia are similar between the two species. In both, the penis guide in inner view narrows towards a truncate apex. However, in lateral view, the inner margin of the tegmen in A. occidentalis is almost straight (Fig. 12 H), whereas in A. potamophilus, it is distinctly sinuate (Fig. 13 E).	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A2CDF54FF29D50D5CDCFF35.taxon	diagnosis	Diagnosis. With its color pattern with paler o-, s- and o-shaped maculae on brown to dark brown elytra, A. pallidipennis is a very distinctive species among Australian species of Aphanocephalus, but also all other congeners. Teneral forms with paler elytral background but frequently with maculae visible. Entirely pale variants can be distinguished after male genitalia examination.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A2CDF54FF29D50D5CDCFF35.taxon	description	Redescription. Length: 1.49 – 2.00 mm, width: 1.07 – 1.62 mm. Body elongate oval about 1.2 – 1.4 times as long as wide (Figs 1 C, 8 G, I – L), moderately convex in lateral view (Fig. 8 H). Body outline appear polygonal as elytral pores slightly protrude from the body outline (Fig. 8 I). Pronotum and elytra covered with long, sparse setae, much denser on pronotum, on elytra, frequently forming a wavy pattern. Most typical form (Figs 5 F, 8 G, L) has head brown, disc of pronotum dark brown with sides paler brown or yellow, elytra brown to dark brown with yellow markings, two o-shaped circles (single on humeral and single on hind area) and a s-shaped macula in discal area of elytron; ventral side brown, hypomera and epipleura rufous, antenna, mouthparts and legs yellow. That basic pattern may vary in size of paler area on the pronotum, and shape of elytral maculae, for example s-shaped macula can be reduced or fused with humeral macula, hind o-shaped macula can be entirely yellow without central brown spot. Moreover, teneral specimens are entirely pale yellow without or with just a shaded macula. Pronotum covered with punctae of single size (Fig. 1 F )). Lateral margins of pronotum bordered, anterior margin without bordering line. Elytra covered with punctae in two sizes (Fig. 1 L), uniformly intermixed. Pronotum and elytra broadly explanate laterally, margins well visible throughout. Lateral sides of elytra sub-parallel, with irregular row of larger punctures slightly depressed along lateral margin of elytra, without pseudopores, pores slightly protruding from the elytral outline, especially in the posterior part, giving somehow polygonal shape. Epipleuron with shallow sub-marginal furrow. Mentum without lateral carinae. Labial palps separated by narrow carina. Prosternum with notosternal carinae absent (Fig. 2 E); prosternal process with lateral carinae absent. Metaventrite slightly longer than ventrite 1. Ventrite 1 longer than ventrites 2 – 4 combined. Ventrite 1 entirely covered with large punctae; ventrites 2 – 5 covered with punctae of two sizes, coarser at base forming a single or double row, and smaller on the rest of surface. Male genitalia. Tegmen in inner view with sides sub-parallel at base then broadly rounded, in apical half tapering toward broadly rounded apex (Fig. 13 C); in lateral view broad at base, pointed at apex, outer margin rounded, inner margin sinusoidal in middle, narrowing toward apex (Fig. 13 B). Penis long, broadening toward apex, outer margin broadly rounded, inner margin slightly rounded (Fig. 13 A); gonopore longer than its width, apex of gonopore extending beyond apex of penis, apically truncate, outer margin broadly rounded (Fig. 13 A). Female genitalia. Coxites narrow, elongate. Sperm duct diverging apically from bursa copulatrix, spermatheca with vermiform basal part and bulbous apical part (Fig. 15 D), apical part with slightly larger diameter than basal part.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A2CDF54FF29D50D5CDCFF35.taxon	discussion	Remarks. Lea (1921 a) described A. pallidipennis from Queensland based on specimens from two localities, Cairns and Little Mulgrave River, however, he did not designate a holotype. Two specimens mounted on the same card from Cairns with the label " TYPE " are deposited in the SAMA collection. The left one with the handwritten " TY " beneath it, is here designated as the lectotype to fix the taxonomic status of this species. In the original description of A. pallidipennis Lea (1921 a), it was written: “ The size and shape are much as those of A. poropterus, but the elytra are reddish and with much less conspicuous punctures; the curious undulations of the clothing, to certain extent, suggest the basal markings of that species ”. This suggests that even for Lea, the external appearance of both species seemed to be very similar. After examining the type material of both species, I believe that the holotype of A. poropterus Lea, 1922 is a dark, fully matured form, and A. pallidipennis Lea, 1921 a is a teneral / pale form of the same species. The same general body shape, with angulate lateral margins of the elytra, subparallel elytral margins, and the same shape of male and female genitalia, support this synonymy. In my analysis of rich materials from various localities, I frequently found both forms (dark and pale) collected from the exact same localities (although the pale form was rarer), which further convinces me that both belong to the same species. That was the most frequently collected species among Australian species of Aphanocephalus. It is worth mentioning that the rich material I have examined for this species (although collected from a relatively small area around Cairns) shows considerable variability in size and color pattern among the specimens examined. This includes variation in the intensity of the background elytral coloration, the contrasting maculation on the elytra, body shape (more rounded or more parallel-sided), the size of punctae on the metaventrite and abdominal ventrites, and slight differences in the shape and proportions of the male genitalia (e. g., the degree of roundness of the apex of the penis guide and slight differences in the shape of the basal part of the penis). These variations may suggest that this could be a complex of cryptic species. However, it is impossible to separate them based solely on morphological characters, as even between species within this species group, the male genitalia are almost identical in shape. Further molecular studies would be necessary to address this question.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A29DF56FF29D62D5CF4FA33.taxon	diagnosis	Diagnosis. Species quite variable in coloration. Rufous specimens of A. potamophilus are most similar to A. calderi sp. nov. in body coloration. However, it can be distinguished from the latter by distinct lateral margins of the elytra, whereas in A. calderi, they are very narrowly explanate. Moreover, A. potamophilus has double-sized punctae on the pronotum, with larger and coarser punctae in the posterior pronotal corners, while in A. calderi, the punctation is single-sized. The central area of the elytra in A. potamophilus are covered with two intermixed sizes of punctae, while in A. calderi it is covered with small punctae of a single size. The male genitalia of A. potamophilus are also most similar to those of A. calderi, but the apex of the tegmen is truncate in A. potamophilus (Fig. 13 F) and rounded in the latter (Fig. 10 I). In lateral view, the penis of A. potamophilus has a less distinctly rounded inner margin (Fig. 13 D) than in A. calderi (Fig. 10 G). Dark specimens of A. potamopilus may also be similar to A. slipinskii sp. nov., both species can potentially overlap in mid Queensland. Then dissection of male genitalia is necessary, in A. potamopilus tegmen is more elongate and slightly narrowing towards truncate apex (Fig. 13 F), while in A. slipinskii sp. nov. tegmen is much shorter, stout, with sides regularly rounded and apex broadly rounded (Fig. 14 F). In A. potamophilus penis in lateral view has less roundly produced inner margin (Fig. 13 D), while in A. slipinskii it is distinctly rounded (Fig. 14 D); also, outer margin of gonopore is slightly hooked in A. potamophilus, while in A. slipinskii it is straight.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A29DF56FF29D62D5CF4FA33.taxon	discussion	Remarks. Lea (1921 a) described A. potamophilus from North Western Australia without designating a holotype. Four specimens, mounted on a single card with the label " TYPE " are deposited in the SAMA collection. The second specimen from the left, with the handwritten " TY " beneath it, is here designated as the lectotype to fix the taxonomic status of this species. The remaining three specimens are paralectotypes. In his publication Lea (1921 a) mentioned that this species was collected near water edges. After describing the species, Lea sent co-types of his newly described species to the British Museum in London. Three decades later, John examined these specimens, but unaware of Lea’s description, he described his species under the same name (using the original name from Lea's label) based on the same specimens. Thus, John's species is both a homonym and a synonym of A. potamophilus Lea. John examined two of Lea’s specimens preserved in the NHM, mounted on a single card: the left specimen is a female, and the right is a male. John did not designate a holotype for his species, but he dissected the male genitalia. Therefore, the male specimen is here designated as the lectotype to fix the taxonomic status of this species. Later John (1959) mentioned that A. potamophilus occurs on the Lord Howe and Norfolk Islands, however, no such specimens were found, so this information needs verification.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

Aphanocephalus punctulatu s is most similar to A. slipinskii in body coloration (dark brown elytra usually with paler humeral areas), however, it can be distinguished by the following set of characters: body distinctly more flattened (Figs 9 C, D) and more elongate (moderately convex in A. slipinskii (Figs 9 H, I) and rather oval body outline); pronotum with dark brown discal macula touching basal pronotal margin (in A. slipinskii discal macula usually separated from basal margin by a narrow light brown / rufous band); scutellar shield brown (yellow in A. slipinskii); mesoventrite, metaventrite and abdomen dark brown (light brown in A. slipinskii). Also, male genitalia of A. punctulatus are diagnostic, tegmen in inner view is elongate with penis guide slightly narrowing towards apex (Fig. 13 I), while in A. slipinskii tegmen is much shorter, and more stout with sides regularly rounded (Fig. 14 F).	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A15DF69FF29D0655A1FF838.taxon	diagnosis	Diagnosis. Aphanocephalus slipinskii is most similar to A. punctulatus in body coloration (dark brown elytra usually with paler humeral areas), however, it can be distinguished by the following set of characters: more convex (Fig. 9 H, I) and more rounded body outline (flattened and more elongate in A. punctulatus - Fig. 9 C, D); pronotum with dark brown discal macula usually separated from basal margin of pronotum by narrow light brown / rufous band (in A. punctulatus discal macula usually touching posterior margin); scutellar shield yellow (brown in the latter species); mesoventrite, metaventrite and abdomen light brown (dark brown in A. punctulatus). Also, male genitalia of A. slipinskii are diagnostic, tegmen in inner view is much shorter, and more stout with sides regularly rounded (Fig. 14 F), while in A. punctulatus tegmen is elongate with penis guide slightly narrowing towards apex (Fig. 13 I).	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).

039A2D1C0A16DF6BFF29D7F05D57F9E1.taxon	etymology	Etymology. The specific name “ weiri ” is a patronym in honor of Tom Weir, an Australian coleopterist, and one of the collectors of the type series.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae). Zootaxa 5632 (3): 401-440, DOI: 10.11646/zootaxa.5632.3.1, URL: https://doi.org/10.11646/zootaxa.5632.3.1
039A2D1C0A16DF6BFF29D7F05D57F9E1.taxon	diagnosis	Diagnosis. Aphanocephalus weiri can be distinguished from other Australian Aphanocephalus species by its rounded oval body outline, brown dorsal coloration with two large yellowish-brown maculae on each elytron, and moderately long vestiture. A similar coloration can be observed in A. blackburni; however, it has a more elongate body outline and a black dorsum clothed with short setae. It can also be similar to A. leai, but in that species, the anterior macula is distinctly angled, whereas in A. weiri, it is transverse-oval. The male genitalia, with an apical hook-like projection on the penis gonopore, are very unique among Australian species.	en	Szawaryn, Karol (2025): Revision of the Australian species of Aphanocephalus Wollaston (Coleoptera: Discolomatidae).
