HOLOTYPE (sex unknown): Western Australia: Kununurra W.A. 12.xii.1983 A.Postle ( ANIC) . PARATYPE: Western Australia: Wyndham W.A. 11 Jan 30 T. Campbell (1 ♀, ANIC) .

Diagnosis. Pronotum angulate (tuberculate) laterally, disc punctate-rugulose laterally, smoother above, either side of central impression strongly tumescent; elytra notably broader than pronotum, dark with orange humeral, fasciate and apical maculations, the transverse fascia widening broadly towards lateral margins and narrowly at suture (anteriorly running along suture longer than posteriorly), punctation without nodules, 8 th stria beginning at 6 th punctation of 7 th stria, all striae terminating at apical macula, more than one seta across interstrial width; femora predominantly yellow basally, black or brown apically, tarsi with three ventral tarsal pads.

Description. Habitus: Fig. 142 . Total length: 7.45–8.1 mm (holotype, 7.45 mm). Head: Cranium black, clypeus and supra-antennal elevations with reddish hue, anteclypeus semi-transparent orange, labrum and antennae orangebrown, palpi orange; eyes separated by about 0.5 eye widths; frons narrow, more rugulose than punctate, upper part of frons partly glabrous, lower part (above epistomal suture) transversely rugulose; clypeus punctate laterally, smoother medially; genae and submentum wrinkled; exterior margins of terminal palpomeres about 1.4 times (maxillae) and 2.3 times (labium) the length of inside edges; antennae not reaching base of pronotum; eyes and most of cranium vested with long erect setae, frons and vertex with shorter medially-directed setae. Prothorax: Black or dark brown; pronotum about 1.15 times longer than wide, robust, sides angular (tuberculate), widest in middle; subapical depression deeply v-shaped, central impression small and deep, a weak impression above lateral tubercle, either side of central impression strongly tumescent, in middle at base weakly tumescent; disc conspicuously punctate-rugulose laterally, disc above, and pronotal arch, smoother with smaller punctation; welldistributed with very fine short setae (sometimes in tuft-like clusters around tumescent parts) and fewer long erect setae. Pterothorax: Sternites brown, with fine pale posteriorly-directed setae; elytra notably wider than pronotum, black or dark brown with orange markings, each elytron with a large apical macula, a broad transverse fascia which widens towards lateral margins and expands just before suture (anteriorly running along suture longer than posteriorly), and a small, less well-defined, humeral macula; length to width ratio 2.27–2.45:1 (holotype, 2.45:1); 8 th stria beginning near anterior margin of fascia, at about 6 th punctation of 7 th stria, all striae reaching apical macula; punctation circular, without nodules; epipleurae extending half way into apical macula; interstriae dense with very short, fine, setae (>3 per puncture, often several setae across interstrial width), plus slightly longer erect setae (<1 per puncture). Legs: Basal half of profemora and basal three-fifths of meso- and metafemora yellow, femora black or brown apically, tibiae and tarsi brown, ventral tarsal pads orange; profemora slightly swollen, other femora slender. Abdomen: Brown. Male genitalia: Unknown.

Etymology. The specific epithet labris (from Greek ‘labrys’, a double-bladed axe) refers to the shape of the elytral fasciate maculae.

Biology. Adults have been collected during December and January.

Distribution (Map 1). Ancyropilus labris sp. nov. is known only from two specimens collected in the northeastern corner of Western Australia.

Remarks. Most abdominal dissections made during the present revision were done so for the purpose of documenting male morphology. The relatively swollen abdomen of the A. labris holotype is far more suggestive of a female than a male. The integrity of the specimen was therefore maintained as the risk of causing damage to the specimen for no diagnostic gain was deemed high.
