Diagnosis. Pronotum tuberculate laterally, disc flattened, impressed in middle, not heavily punctate (most densely punctate laterally); elytra dark with yellowish fasciate and apical maculations (humeral maculae absent), the transverse fascia curved before (not meeting at) the suture, punctation without nodules, 8 th stria beginning near base, all striae reaching apical macula, interstrial setae in single rows; femora yellow and brown, tarsi with three ventral tarsal pads.

Platynotum culgoense sp. nov. differs from P. femorale comb. nov. and P. gracile sp. nov. by its flatter pronotal disc, complete 8 th elytral striae, the pre-sutural rounding-off of the elytral fascia and by its smaller size.

Description. Habitus: Fig. 177. Total length: 6.6–7.1 mm (holotype 7 mm). Head: Cranium blackish to dark brown, submentum and gula region paler, clypeus and supra-antennal elevations infused with reddish-black, anteclypeus semi-transparent orange, antennae, labrum and palpi orange-brown; eyes separated by 1.14–1.26 eye widths (holotype 1.2); vertex with numerous well-spaced punctations laterally, partly impunctate medially, frons punctate mostly around eye margins with few medial punctations (largely smooth medially), impunctate area in upper part of frons slightly elevated; genae wrinkled; submentum smooth; exterior margins of terminal palpomeres about 1.5 times (maxillae) and 3 times (labium) the length of inside edges; antennae almost reaching base of pronotum; vertex and lower part of frons with fine pale erect or medially-directed setae. Prothorax: Light to dark brown, pronotum 1.2–1.27 times longer than wide (holotype 1.26), sides with weak lateral tubercle behind middle; pronotal arch extremely short laterally, almost as wide as pronotum at tubercles; disc notably compressed and broadly impressed in middle; subapical depression broadly v-shaped and adjoining linear central impression, lateral impression obscure, positioned anterior of lateral tubercle; disc lightly punctate around central impression, heavily punctate-rugulose laterally, elevated areas less punctate or impunctate; disc with numerous short fine multidirectional setae and occassional long erect setae. Pterothorax: Ventrites brown to orange-brown, vested with short pale and occasional long setae; elytra dark or light brown with orange to yellowish markings (each elytron with an apical macula and a broad transverse fascia which is rounded-off before, and not meeting at, the suture); length to width ratio 2.75–2.93:1 (holotype 2.75); 8 th stria beginning near base, only slightly shorter than 7 th stria, all stria reaching apical macula, punctation lacking internal nodules, relatively uniform in size along full elytral length, punctation of outer striae often smaller than those of inner striae, epipleurae extending to apical maculae; interstriae with very fine short erect setae (often 1 per puncture) and longer thicker erect setae (about 1 per every 3 or 4 punctures), intrafoveal setae about half a puncture diameter in length. Legs: Coxae brownish, approximately basal half of profemora and about basal three-fifth to two-thirds of meso- and metafemora yellow, femora broan apically, demarcation of yellow and brown parts of profemora unclear on some specimens, tibiae and tarsi pale brown, ventral tarsal pads yellowish; profemora notably swollen, other femora moderately swollen; tibial spurs solid, particularly protibial spur. Abdomen: Ventrites orange or brownish. Male genitalia: Tegmen (Fig. 62) relatively slender, needlelike, widest at bend of tegminal arms, evenly tapering to parameroid lobes, the latter narrow acuminate and slightly bent laterally, dorsal sinus short, about one-sixth tegmen length, narrow internally, opening externally, ventral sinus similar in length, tegminal arms gradually meeting short (about one-eighth tegmen length) apodeme; median lobe as in (Fig. 98) with apical process; pygidium as in Fig. 134.

Etymology. This species is named after the collecting locality of the male holotype, Culgoa Floodplains National Park, which is situated at the Queensland and New South Wales border at longitude 147° east.

Biology. Specimens were collected from September to February by setting up Malaise traps in Eucalyptus and Acacia plant communities.

Distribution (Map 2). Southern and central Western Queensland.

Remarks. The species group name Notopilo culgoaensis, published in the 2009-2010 Bush Blitz survey report for north-western New South Wales and southern Queensland (ABRS 2014a, b) with no accompanying description and without reference to a name-bearing type, is deemed unavailable (ICZN 1999, Article 16.4).
