Diagnosis. Pronotum round laterally, disc punctate-rugulose,either side of central impression strongly tumescent; elytra notably broader than pronotum, each elytron dark with a large slightly angulate transverse fascia which meets at the suture and an obscure basal macula; punctation with small nodules; 8 th stria beginning near base; striae 3-7 terminating at apical slope (other striae shorter); femora entirely brown; tarsi with three ventral tarsal pads.

Description. Habitus: Fig. 175 . Total length: 7.9 mm. Head: Cranium black, clypeus and supra-antennal elevations with reddish hue, anteclypeus, labrum and palpi orange-brown, antennae brown; eyes separated by about 0.92 eye widths; upper part of frons punctate-rugulose, lower part with weak transverse wrinkles; genae and submentum wrinkled; exterior margins of terminal palpomeres about 1.5 times (maxillae) and 2.5 times (labium) the length of inside edges; antennae almost reaching base of pronotum; eyes and most of cranium vested with long erect setae, frons and vertex with shorter medially-directed setae. Prothorax: Black, reddish-black in parts; pronotum about 1.11 times longer than wide, sides rounded, widest in middle; subapical depression deeply v-shaped; central impression deeply excavated, weakly sulcate; either side of central impression strongly tumescent; disc unevenly punctate-rugulose, pronotal arch smoother, spaces between individual punctures sub-nitid; numerous fine short multi-directional setae plus fewer long erect setae. Pterothorax: Sternites reddish-brown, with fine pale posteriorlydirected setae; elytra ( Fig. 16 ) about 1.4 times wider than pronotum, blackish brown with orange markings (each elytron with a large, slightly angulate, transverse fascia which meets at the suture plus an obscure brown triangular maculation its outer-most margin extending from the humerus to inner corner of fascia; apices lacking maculae); length to width ratio 2:1; 8 th stria beginning near base; striae 3–7 reaching apical slope, other striae shorter; punctures with small lateral nodules (most clearly visible in basal punctures), relatively well-spaced; basal intervals at least one puncture width, wider towards apex (punctures gradually smaller towards apex); epipleurae terminating within apical curve; intervals with many short fine, and less frequent longer, setae (much of the discal setae rubbed off holotype), intrafoveal setae short; hindwing with CuA 3+4 and CuA 1 cross-veins complete, MP 3+4 absent basad of CuA 1 cross-vein. Legs: Femora, tibiae and tarsi brown, ventral tarsal pads brownish yellow; profemora slightly more swollen than other femora; front and middle legs stout, hind legs more elongate. Abdomen: Orange-brown. Male genitalia: Tegmen ( Fig. 60 ) subparallel, heavily sclerotised structural H-shaped ‘frame’ more apparent than in congeners, parameroid lobes with relatively thick terminal sub-digitiform processes, dorsal sinus deep and wide, about one-third tegmen length, internally with preapical membrane (potentially sensory in function), ventral sinus almost two-thirds as long as dorsal sinus, apodeme very short, spatulate, about one-tenth tegmen length; median lobe as in Fig. 96 ; pygidium as in Fig. 132 .

Etymology. The specific epithet, obesus (Latin, meaning fat) refers to the barrel-shaped form of this species which makes it instantly recognisable amongst its congeners.

Biology. Specimens were captured in a static panel trap containing an alpha-pinene+ethanol lure, or collected at light.

Distribution (Map 4). The four known specimens were collected in Queensland (Gladstone and Brisbane) and New South Wales (Blaxlands Ridge).
