HOLOTYPE ♁: Queensland: Qld: 4km SE HS Noonbah Station (NB2 M), 198m, 24.137° Sx 143.207°E, 19Jan-7Feb2009, Malaise, A. Emmott, Mulga, 17253 (QM, type reg. T258548). PARATYPE: Queensland: same data as holotype (1 ♀, QM).

Diagnosis. Pronotum robust, disc very densely punctate except narrow longitudinal stripe from central impression to pronotal furrow lacking punctation; elytra blackish-brown with orange fasciate and apical maculations, fasciae rounded before suture, humeral maculae absent, punctation lacking nodules, 8 th stria almost complete, only slightly shorter than 7 th stria, all striae complete to apical maculae; femora yellow basally, brown apically, only profemora slightly swollen; tarsi with three ventral tarsal pads.

Ancyropilus noonbahensis sp. nov. is most similar to Ancyropilus simplex sp. nov. though differs from it by the tegmen with parameroid lobes entirely chitonised externally and U-shaped dorsal sinus, the femoral bases yellow, and the elytral apices clearly marked with a small yellow macula.

Description. Habitus: Fig. 144. Total length: 7.2–8 mm (holotype, 7.2 mm). Head: Cranium black (submentum and gula paler in holotype only), clypeus and supra-antennal elevations reddish-black, anteclypeus semi-transparent orange, labrum and pre-ultimate palpomeres orange, terminal palpomeres and antennae darker orange or brownish; vertex and frons with dense network of irregularly-shaped punctation which becomes transversely rugulose before epistomal suture, clypeus more punctate than rugulose basally, smooth apically; anterior clypeal margin broadly concave; eyes separated by 0.69–0.72 eye widths; genae wrinkled; terminal maxillary palpomeres with exterior margins about 2 (females and males) times the length of inside edges; terminal labial palpomeres with exterior margins about 2.5 (females and males) times the length of inside edges; antennae almost reaching base of pronotum; long and short, erect or medially-directed, pale setae. Prothorax: Blackish-brown; pronotum 1.14–1.22 times longer than wide, widest at the middle, sides almost angular in male holotype, more rounded in female paratype, lateral impression obscure, subapical depression v-shaped, not well-defined due distribution of punctation, central discal impression open; disc very densely punctate except a conspicuous slender impunctate longitudinal line from central sulcus to pronotal collar, pronotal arch and collar less densely punctate; pale fine multi-directional setae and thicker long erect setae. Pterothorax: Ventrites black or brownish, metaventrite conspicuously punctate, with short pale posteriorly-directed setae; elytra blackish-brown with orange maculations (each elytron with a small pre-apical macula and a broad fasciate band rounded at the suture); length to width ratio 2.61–2.79:1; punctation large, circular, anterior of fascia, smaller posterior of fascia, without internal nodules, all striae terminating near apex, 8 th stria beginning near base; interstriae about as wide as corresponding punctures, with rows of fine erect setae (> 1/ puncture) and longer erect setae every few punctures; epipleurae extending into apical curve; hindwing with CuA 3+4 and CuA 1 cross-veins complete, MP 3+4 substantialy extended basad of CuA 1 crossvein. Legs: Basal third of profemora and half or just less than half of meso- and metafemora yellow, apical two-thirds of profemora and half or slightly more than half of meso- and metafemora dark brown, tibiae and tarsi brown, ventral tarsal pads brownish-yellow; profemora slightly swollen, other femora more slender. Abdomen: Ventrites orange-brown. Male genitalia: Tegmen (Fig. 31) sinuate between equally broad base and parameroid lobes, parameroid lobes slightly bent inwards, apically with broad acumination, dorsal sinus slightly longer than one-quarter tegmen length, externally wide open, internal shape sub-spatulate, interrupted by opening with short membranous lobes which bear a row of setae, ventral sinus of similar length, apodeme about one-fifth tegmen length; median lobe as in Fig. 70; pygidium as in Fig. 106.

Etymology. The specific epithet, noonbahensis, refers to Noonbah Station, a property in western Queensland where the type specimens were collected.

Biology. The type series was taken in a single Malaise trap set up over the period 19 January to 7 February in mulga (Acacia) scrub.

Distribution (Map 1). Ancyropilus noonbahensis sp. nov. is known only from Noonbah Station in Western Queensland.
