Diagnosis. Pronotum tuberculate laterally, disc flattened, impressed in middle, not heavily punctate (most densely punctate laterally); elytra dark with poorly-defined orange humeral, fasciate and apical maculations (apical maculae extremely faint on one specimen), the transverse fascia meeting at the suture, punctation with small lateral nodules (more easily observed at middle fascia), 8 th stria beginning near base, all striae terminating near apex, interstrial setae mostly in single rows (occasionally more than one seta across interstrial width); femora yellow and brown, tarsi with three ventral tarsal pads.

Description. Habitus: Fig. 176 . Total length: 11–13 mm. Head: Cranium dorsally black, cranium ventrally, clypeus and supra-antennal elevations reddish-black, anteclypeus semi-transparent pale orange, labrum, palpi and antennae darker orange or brownish; vertex moderately punctate, frons smooth medially, punctate laterally; anterior clypeal margin concave; eyes separated by 0.91–1.12 eye widths; genae wrinkled; submentum smooth; terminal maxillary palpomeres with exterior margins about 1.6 (females and males) times the length of inside edges; terminal labial palpomeres with exterior margins about 2.2 (females and males) times the length of inside edges; antennae not reaching base of pronotum; long and short, erect or medially-directed, orange setae, those of vertex and frons fine. Prothorax: Reddish-black; pronotum 1.18–1.26 times longer than wide, anterior part as wide as middle, sides conspicuously constricted between, subapical depression well-defined, v-shaped; disc dorso-ventrally compressed (appearing pressed in) ( Fig. 17 ), central discal impression a linear sulcus; disc appearing smooth, though punctate and/or semi-rugulose in parts; yellowish fine multi-directional setae and thicker long erect setae. Pterothorax: Ventrites orange or brown, with orange posteriorly-directed setae; elytra dark brown, each elytron with ill-defined orange-brown maculate areas (a large basal macula, a fasciate band near middle and some specimens with an apical spot); length to width ratio 2.63–2.78:1; punctation with small lateral nodules (most easily observed at middle fascia), all striae terminating near apex, 8 th stria complete at base; interstriae about as wide as corresponding punctures, with very fine semi-erect setae (sometimes>1 per punctation) and less frequent longer erect setae, setae mostly in singular rows, occassionaly more than one seta across interstrial width; epipleurae extending into apical curve. Legs: Femora except extremities yellow, tibiae, tarsi and femoral extremities brown, ventral tarsal pads yellowish; femora swollen, profemora more than other femora. Abdomen: Ventrites orange. Male genitalia: Tegmen ( Fig. 61 ) reasonably slender, slightly constricted in middle, parameroid lobes arcing laterally before almost meeting apically, tegminal arms apparently formed as an extension of a more heavily sclerotised H-shaped internal ‘frame’, dorsal sinus about one-fifth of tegmen length, broad internally, narrowed apically, ventral sinus about as long as dorsal sinus, tegminal arms tapering sharply to meet apodeme near basal one-seventh; median lobe ( Fig. 97 ) with membranous apex; pygidium as in Fig. 133 .

Etymology. This species is named after Richard Bull in appreciation for the small, but interesting collection of clerids (the paratype from Zircon Patch among them) that he gifted to the first author.

Biology. Adults have been collected in October, November and March.

Distribution (Map 2). This species is known from four arid zone localities, two each in the Northern Territory and Western Australia.
