Diagnosis. Pronotum goblet-shaped, widest anteriorly, disc well-punctated though retaining a smooth appearance, central sulcus absent; elytra yellow with a broad dark pre-apical fascia and smaller dark patches between it and the base, punctation with nodules, 8 th stria beginning near base, striae terminating within apex; legs yellow with longitudinal carinae and tarsi brownish, tarsi with three ventral tarsal pads.

Description. Habitus: Fig. 161 . Total length: 7.1–7.7 mm (holotype, 7.1 mm). Head: Cranium dark brown dorsally and laterally, orange ventrally, anteclypeus, labrum, palpi and antennae orange or orange-brown; vertex and frons densely punctate to semi-rugulose, frons broad, eyes separated by 1.75–2 eye widths (holotype, 1.75), a shallow inconspicuous impression at narrowest point, surface becoming less punctate below, clypeus mostly smooth, anterior margin strongly concave, genae wrinkled; exterior margins of terminal palpomeres about 1.2 times (maxillae) and 1.8 times (labium) the length of inside edges; antennae notably long, reaching beyond base of pronotum, all segments, including club, elongated; eyes and most of cranium vested with erect pale setae, above eyes with a cluster of shorter posteriorly-directed setae, frons with shorter medially-directed setae. Prothorax: Entirely orange-brown; pronotum 1.08–1.12 times longer than wide (holotype, 1.12), goblet-shaped, anteriorly slightly broader than middle and about as wide or slightly narrower than head, sides rounded, subapical depression poorly defined though v-shaped, central sulcus absent; disc well-distributed with small shallow punctation though smooth (glossy) in appearance, moderately distributed with short fine multi-directional setae and occasional long erect setae. Pterothorax: Ventrites yellow, moderately vested with short pale and occasional long setae; elytra yellow with brownish markings (a broad pre-apical fascia crossing the suture and a small round spot between the base and fascia); length to width ratio 2.88–3.13:1 (holotype, 3.13:1); punctation with lateral nodules, nodules less visible around elytral mid-length, punctation appearing larger than actual size due to visibility of subcutaneous striate structures, striation strong until near apex, 8 th and 9 th striae beginning at base; interstriae with very fine erect setae (approximately one per punctation) and less frequently with longer erect setae, intrafoveal setae long; epipleurae extending well into apical curve; hindwing with CuA 3+4 cross-vein absent, CuA 1 cross-vein complete, MP 3+4 absent basad of CuA 1 crossvein. Legs: Femora and tibiae yellow, tibial carinae dark, tarsi brown, ventral tarsal pads yellowish; profemora barely swollen, other femora slender. Abdomen: Ventrites yellow to orange. Male genitalia: Tegmen ( Fig. 47 ) slightly widening towards parameroid lobes which taper apically to slender digitiform processes, dorsal sinus just over one-third tegmen length, weakly narrowing internally, ventral sinus two-thirds as long, tegminal arms tapering gradually then sharply meeting apodeme near basal one-tenth; median lobe as in Fig. 85 ; pygidium as in Fig. 120 .

Etymology. The specific epithet xanthoprolatus (from Greek ‘xanthos’ meaning yellow, and Latin ‘prolatus’ meaning elongated), refers to this species being the more elongated of the two, primarily yellowish, flightless species.

Biology. Adults have been collected in November using pitfall traps.

Distribution (Map 3). The two known specimens are from one locality 115 km north of Port Augusta in South Australia.
