Distribution Range. Found from Townsville, Queensland northward up the Cape York Peninsula and west across Northern Territory ( Fig. 20 View Fig ).

Notes. Size ranges among the specimens examined are sbl = 4.3–5.3 mm, elytral width = 1.4–1.9 mm, and ocular ratio = 1.33–1.43. This species was moved from Holconotus   to Pediomorphus   by Will (2015). Straneo (1960) included only the holotype and an allotype under his species and deferred several other specimens that were smaller; he noted they varied enough to cause him to suspect they were other species. He was correct, and two of those specimens are included here under Pediomorphus semilaevis Will   , new species.

Pediomorphus maximus Will   , new species Zoobank.org/ urn:lsid:zoobank.org:act:30B9600A-D29A-4E68-A8B8-CC61AF2541E8 ( Figs. 6 View Figs , 19 View Fig )

Type Material. HOLOTYPE: Female. //“NSW; Omeo; -30:3:32; 148:54:14; Feb 2001 to [blank]; I. [Ian] Oliver, DLWC [ NSW Department of Land and Water Conservation]; WALCOLOO291 (pit trap)”// “K 177034”// “ U.C. Berkeley EMEC 1003862 View Materials ”// [deposited AMS].  

Type Locality and Range. Only known from the type locality as given on the holotype. Omeo is the name of a homestead approximately 56 km WNW of Wee Waa ( Fig. 20 View Fig ), along Kamilaroi Highway. It is at approximately 160 m elevation and is largely open eucalyptus forest and pastureland.

Diagnosis. This species and Pediomorphus storeyi Will   , new species, are the largest species in the genus, with P. maximus   being slightly broader, more robust, and with a more depressed form. Its size and sulcate, nearly impunctate elytral striae distinguish it from other species in the genus.

Description. Size: sbl = 8.2 mm; greatest width across elytra = 3.1 mm. Color: Dorsal and ventral surfaces piceous to dark rufous; legs, mouthparts, and antennae paler rufous. Dorsally distinctly and ventrally moderately shiny. Iridescence not evident on head and pronotum, spectral iridescence apparent on elytra and proepisterna, otherwise not evident on ventral surface of body. Head: Dorsal microsculpture not evident at 50X magnification. Clypeal-ocular impressions broad, widening posteriorly, distinctly delimited laterally by convexity, not clearly delimited medially. Ocular ratio 1.43. Eyes relatively small, prominent, with large posterior orbital area, single subocular carina low, sharply defined. Labrum with anterior margin straight. Median tooth of mentum broad, flat across apex. Antennae moderately long, antennomeres 10–11 surpassing pronotal base. Thorax: Pronotum dorsally impunctate, microsculpture not evident at 50X magnification on anterior half, irregular, somewhat stretched mesh evident near base. Widest anteriad of middle, lateral margins distinctly sinuate in basal half.Lateral marginal bead widened near hind angles; basal margin without marginal bead; anterior angles prominent, broadly triangular; hind angles widely obtuse, not denticulate; basal impressions linear, well-impressed, reaching basal margin. Seta at hind angle in marginal bead. Elytra parallel-sided, epipleura in dorsal view evidently sinuate at level of umbilicate marginal puncture 7. Elytral striae sulcate, with very shallow, irregular punctures more conspicuous near base but not crenulate-punctate. Elytral microsculpture scarcely evident as very transversely stretched sculpticells. Intervals slightly convex. Elytral plica minute. Prosternal process rounded, with very shallowly marked margin, most evident laterally. Prosterna smooth. Meso- and metasterna coarsely punctate. Abdomen: Abdominal ventrites densely, finely punctate laterally and basally, impunctate medially and apically.

Etymology. The specific epithet is the Latin masculine nominative maximus   , which is a reference to the relatively large size of these beetles.

Berkeley EMEC 705,231”// [deposited AMS].

Type Locality and Distribution Range. Only known from the location on the holotype label. This location is about 23 km south of Weemelah ( Fig. 19 View Fig ) at approximately 170 m elevation in habitat of Casuarina cristata Miq.   ( Casuarinaceae   ). The pitfall traps that collected this specimen were on the “[e]ast side of road leading due South from Weemelah, approximately 150m North of bridge over Gingham Watercourse” (D. Smith, AMS, in litt.).

Diagnosis. Very similar in form to a small individual of P. planiusculus   . The less dense, deeper, and larger punctures of the elytral striae in P. crenulatus   distinguish it from P. planiusculus   ( Figs. 15–16 View Figs ).

Description. Size: sbl = 5.1 mm; greatest width across elytra = 1.5 mm. Color: Dorsal and ventral surfaces brunneo-rufous, slightly infuscated on elytral disc; legs, mouthparts, and antennae concolorous with ventral surface.

Head: Dorsal microsculpture not evident at 50X magnification. Clypeal-ocular impressions very divergent, broad, and shallow, poorly delimited laterally, not clearly delimited medially. Ocular ratio = 1.50. Eyes relatively small, prominent, with large posterior orbital area, single subocular carina low, sharply defined. Labrum with anterior margin slightly convex. Median tooth of mentum triangular, slightly flat across apex. Antennae moderately long, antennomeres 10–11 surpassing pronotal base. Thorax: Pronotum dorsally impunctate except for a few irregular, very small punctures near base in and around basal impressions and along basal margin; microsculpture not evident at 50X magnification, cordiform, widest well anteriad of middle, lateral margins distinctly sinuate in basal third. Lateral marginal bead narrow and widened just at hind angles; basal margin without marginal bead, somewhat irregular punctate; anterior angles not prominent, broadly rounded-triangular; hind angles obtuse, not denticulate; basal impressions linear, shallowly impressed, reaching basal margin. Seta at hind angle in marginal bead. Elytra parallel-sided, epipleura in dorsal view evidently sinuate at level of umbilicate marginal puncture 6. Elytral striae crenulate-punctate. Elytral microsculpture not evident at 50X magnification. Intervals flat except slightly convex in apical fifth. Elytral plica small. Prosternal process rounded, margined. Prosterna smooth. Meso- and metasterna coarsely punctate. Abdomen: Abdominal ventrites densely, finely punctate laterally and basally, impunctate medially and apically. Aedeagus: Medium lobe long and thin in lateral view, tip roundly acuminate in ventral view, no evident spines, fields, or spinules on endophallus in repose.

Etymology. The specific epithet is the Latin masculine nominative crenulatus   , which is a reference to the relatively large punctures in the elytral striae that cause the striae to be crenulated in these beetles.

Seta at hind angle in marginal bead. Elytra parallel-sided, dorsally depressed, epipleura in dorsal view very slightly sinuate at level of umbilicate marginal puncture 7. Elytral striae finely, shallowly crenulate-punctate. Elytral microsculpture hardly evident at 50X magnification, where apparent very transverse. Intervals very slightly convex, more convex in apical third. Eltral plica large, prominent. Prosternal process rounded, deeply margined. Prosterna smooth except for cluster of fine punctures medially. Meso- and metasterna coarsely punctate. Abdomen: Abdominal ventrites densely punctate, shallowly rugose. Aedeagus: Medium lobe short in lateral view, tip emarginate in ventral view, no spines or spinules visible on endophallus in repose.

Type Locality. Kununurra, Western Australia, in the vicinity of 15°47’ S 128°45’ E ( Fig. 19 View Fig ). The area has an elevation of about 50 m. Where not modified, the habitat is open savanna woodland and Ord River riparian drainage GoogleMaps   .

Diagnosis. Similar to P. variabilis   but with the pronotal hind angles obtuse and not prominent. The male genitalia have several evident spine fields.

Description. Size: sbl = 5.4 [4.8–5.8] mm; greatest width across elytra = 1.9 [1.3–2.0] mm. Color: Dorsal and ventral surfaces castaneous; legs, mouthparts, and antennae concolorous or slightly paler brunneous. Dorsally distinctly and ventrally slightly shiny to moderately dull. Dorsally with spectral iridescence, venter, elytral epipleura, and legs with or without slight spectral iridescent. Head: Dorsal microsculpture not evident at 50Xx magnification. Clypeal-ocular impressions shallow, short, parallel, poorly delimited. Ocular ratio = 1.43 [1.43–1.56]. Eyes relatively large size, somewhat prominent, with small posterior orbital area, single subocular carina long, sharply defined, in some a second, short, low carina and region slightly rugose. Labrum with anterior margin slightly convex. Median tooth of mentum narrow, rounded or emarginate across apex. Antennae very long, antennomeres 8–11 surpassing pronotal base. Thorax: Pronotum dorsally with distinct punctures only in and around basal impressions, microsculpture not evident at 50X magnification. Pronotum widest across middle, lateral margins converging to base, not or only very slightly sinuate. Lateral marginal bead narrow, widening slightly near base and ending just at hind angles or rarely extending slightly and obscurely along base where bead, when present, is interrupted by irregular puncture; basal margin without marginal bead; anterior angles not prominent, broadly roundedtriangular; hind angles widely obtuse, not denticulate; basal impressions linear, broad, shallowly impressed, reaching basal margin. Seta at hind angle in marginal bead. Elytra parallel-sided, dorsally very depressed, epipleura in dorsal view very slightly sinuate at level of umbilicate marginal puncture 7. Elytral striae finely, shallowly crenulate-punctate. Basal third of striae 6–7 shallower and more coarsely punctate than other striae. Elytral microsculpture not evident at 50X magnification. Intervals flat or very slightly convex, more convex in apical third. Elytral plica very small, elongate. Prosternal process shallowly rounded to somewhat flattened, apically margined. Prosterna smooth except for a few very shallow, fine medial punctures. Meso- and metasterna coarsely punctate. Abdomen: Abdominal ventrites densely, finely, shallowly rugose. Aedeagus: Medium lobe long, with thin apical region slightly turned ventrally in lateral view, tip rounded in ventral view, 4 evident fields of spinules visible on endophallus in repose.

Etymology. The specific epithet is the Latin masculine nominative obtusus   , which is a reference to the bluntly obtuse pronotal hind angles in these beetles.
