Diagnosis. Pronotum rounded laterally, disc smooth with minimal punctation; elytra dark with orange fasciate and apical maculations, humeral maculae absent, punctation without obvious nodules, 8 th stria complete, striae terminating within fascia; femora yellow basally, brown apically, tarsi with three ventral tarsal pads.

Notopilo brevistriatus sp. nov. is easily separated from the superficially similar N. variipes comb. nov. by the lack of obvious nodules within elytral punctation, the absence of elytral punctation posterior to fascia, the wider separation of the eyes and by its Western Australian distribution.

Description. Habitus: Fig. 169. Total length: 12–16.62 mm (holotype 14.9 mm). Head: Vertex, frons, genae and submentum blackish, clypeus and supra-antennal elevations reddish-black, anteclypeus transparent yellow/ orange, antennae, labrum and palpi orange; eyes separated by 0.85–1.1 eye widths (holotype 0.85); vertex and frons mostly smooth with only occasional small seta-associated punctations, frons slightly raised above clypeus; genae and submentum wrinkled; exterior margins of terminal palpomeres about 2–2.2 times (maxillae) and 2.3–3 times (labium) the length of inside edges; antennae quite long, reaching beyond base of pronotum; eyes and most of cranium vested with erect pale setae, frons with slightly shorter medially-directed setae. Prothorax: Blackishbrown, venter, pronotal collar and arch sometimes paler; pronotum 1.2–1.3 times longer than wide (holotype 1.24), sides round, widest at middle; subapical depression deeply v-shaped, disc centrally sulcate (sulcus smooth, more open than linear) and with obscure lateral sulci, surface smooth, almost impunctate; moderately distributed with long erect setae and shorter finer multi-directional setae. Pterothorax: Ventrites reddish-brown, vested with short pale and occasional longer setae; elytra dark reddish-brown with orange markings (each elytron with a large apical macula and a transverse fascia), length to width ratio 2.95–3.12:1 (holotype 3.06); 8 th stria beginning near base, all striae terminating at or within fascia, punctation large, circular, apparently without nodules (vestigial nodules visible in some specimens as darker pigmented spots on lateral inside edges of punctures), interstices smooth, epipleurae extending into apical curve, interstriae with very fine short semi-reclinate setae (>1 per puncture) and longer thicker erect setae (<1 per puncture), intrafoveal setae very short; hindwing with CuA 3+4 cross-vein complete, CuA 1 crossvein absent. Legs: Mostly yellow, tip of femora, base of tibiae and tarsi brown, ventral tarsal pads paler; femora slender (profemora thicker but not particularly swollen). Abdomen: Ventrites orange. Male genitalia: Tegmen (Fig. 54) broadest apically, slightly narrowed between parameroid lobes and tegminal arms, dorsal sinus broad and opening apically, just less than one-third tegmen length, ventral very short, about two-thirds as long, apodeme about one-quarter tegmen length; median lobe as in (Fig. 91); pygidium as in Fig. 126.

Etymology. The specific epithet brevistriatus (from Latin ‘brevis’ meaning short, and Latin ‘stria’ meaning line) refers to the shortened elytral puncture rows of this species which are not extended beyond the posterior margin of the transverse fascia.

Variation. The dark area posterior of the elytral fascia is almost as dark as the pronotum in some specimens and about as light as the area anterior to the elytral fascia in other specimens.

Biology. The specimens from Wilson Inlet were collected at light while the “Gloucester Tree” specimen was found under bark of Eucalyptus . Specimens have been collected during the period December to March.

Distribution (Map 3). Notopilo brevistriatus sp. nov. is known only from southwest Western Australia.
