Diagnosis. Pronotum rounded laterally, disc without obvious punctation; elytra predominantly yellowish with dark brown maculate areas basally, post-basally and pre-apically, punctation without nodules, 8 th stria beginning near base, striae terminating just beyond elytral mid-length; femora yellow basally, pale brown apically, tarsi with three ventral tarsal pads.

Description. Habitus: Fig. 151 . Total length: 8–10.5 mm (holotype, 9.9 mm). Head: Vertex, frons, clypeus, supra-antennal elevations and genae brown, gular region paler, anteclypeus semi-transparent orange, antennae, labrum and palpi orange-brown; eyes separated by 0.88–1.13 eye widths (holotype, 1.08); vertex and frons mostly smooth with only occasional small seta-associated punctations, frons weakly impressed centrally; genae wrinkled, submentum smooth; exterior margins of terminal palpomeres about 1.5 times (maxillae) and 2 times (labium) the length of inside edges; antennae long, reaching beyond base of pronotum; eyes and most of cranium vested with erect pale setae, frons with slightly shorter mediallydirected setae. Prothorax: Dark brown laterally and disc either side of median-line, pronotal arch, pronotal collar and disc medially pale brown to yellowish; pronotum 1.14–1.27 times longer than wide (holotype, 1.21), sides evenly curved, middle slightly broader than lateral part of pronotal arch; subapical depression shallow v-shaped, disc without central sulcus, pronotum with weak lateral impression, surface smooth, almost impunctate; moderately distributed with long erect setae and shorter finer multi-directional setae. Pterothorax: Ventrites orange-brown to dark brown, vested with short, pale, posteriorly-directed, semidecumbent setae; elytra predominantly yellowish with dark brown maculate areas basally, post-basally and pre-apically (basal area to between 5–7 th puncture from base, post-basal area variable, often triangular, joined to basal area along lateral margin, the pre-apical area beginning immediately where punctures become obsolete); length to width ratio 2.75–2.95:1 (holotype, 2.81); 8 th stria beginning near base, all stria terminating abruptly just beyond elytral mid-length, at junction of larger yellow and brown areas, punctation without nodules, interstriae smooth, often narrower than diameter of punctures, epipleurae extending into apical curve, becoming obscure near apex; interstriae with posteriorly-directed, semi-erect setae about as long as distance between centres of adjacent punctures, plus similar setae of slightly longer length, intrafoveal setae extremely fine and short (most easily observable in dark areas of elytra). Legs: Femora yellow basally, brown apically (basal one-third of profemora and basal half of meso- and metafemora yellow), tibiae and tarsi brown, ventral tarsal pads yellowish or orange; apical two-thirds of profemora moderately swollen, other femora very slightly swollen apically. Abdomen: First ventrite yellowish, other ventrites brown. Male genitalia: Tegmen ( Fig. 39 ) broadest at basal opening (tegminal struts), slightly narrowed before apical inward curve of parameroid lobes, apices pointed; dorsal sinus about one-third tegmen length, narrow internally, broadly opening apically; ventral sinus about half dorsal sinus length; apodeme about one-third tegmen length; median lobe as in Fig. 78 .

Etymology. This species is named after the type locality, Bunya Mountains in Queensland.

Variation. A non-type specimen from Bundaberg has the dark brown colouration more broadly distributed on the prontal disc and elytral base.

Biology. Specimens were collected in November, December and January, one by light trap, in Nothofagus forest.

Distribution (Map 2). So far known from several localities in southeastern Queensland, plus Tooloom in New South Wales.
