Body length, 14.45–23.70 mm; width, 2.95–4.98 mm.  Colour(Fig. 29). Body blackish brown with head, thorax and basal elytra darker. Head (particularly frons and vertex) covered with dense white pubescence except a narrow longitudinal glabrous area on vertex. Pronotal disc with a wide longitudinal stripe of very dense white pubescence on each side; remaining prothorax covered with dense white pubescence. Each elytron with a very vague subtriangular mark covered with relatively sparse hairs, starting from shoulder and extending to about basal 1/3, without any margin; the remaining of elytra with fairly dense white pubescence. Meso- and meta-sterna, abdomen, and legs covered with dense white pubescence. Body colour may vary from blackish brown to blackish.  Head.Postclypeus semicircular and slightly convex, with dense coarse punctures; frontoclypeal suture deep and narrow in middle; distance between lower lobes of eyes 1.82–2.0 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.3–1.67 × as long as distance between eyes on ventral side; genal length 0.25–0.32 × as long as head width immediately below eyes. Antennae shorter than body; segments 5–10 strongly flattened and produced on one side at apex.  Thorax and abdomen. Pronotum 1.05–1.54 × as long as width, with a weak and rounded process at each side; posterior margin 1.16–1.69 × as wide as anterior margin; pronotal disc binodulose in middle area; disc and sides strongly rugose transversely near anterior and posterior margins. Scutellum semicircular, with dense pubescence. Elytra 2.97–3.86 × as long as prothorax and 3.25–3.44 × as long as shoulder width; each elytron with 3 feeble longitudinal carinae; basal elytra finely punctate; apex more or less truncate with a small process or spine at suture. Segment 1 of hind tarsus 0.66–0.68 × as long as sum of segments 2+3. Apex of terminal sternite truncate.  Male terminalia.Apex of ventral lobe strongly emarginate and apex of dorsal lobe rounded or slightly pointed; ventral lobe as long as dorsal lobe; spined region of internal sac 4.89–5.12 × as long as basal unspined regions; spined region divided into two sections without unspined gap between sections; first section with dense clusters of long simple spines and fairly dense multi-branched spines at lateral sides; second section with sparse multi-branched spines and fairly dense simple spines ( Fig. 67a). Eighth sternite obliquely truncate or nearly rounded at sides, shallowly emarginate at apex, with long and fairly long setae arising terminally; ventral surface with fairly dense cloud-like processes ( Fig. 67b). Eighth tergite rounded at apex, with fairly dense simple spines and multi-branched spines near base ( Fig. 67c). Paramere robust, 1.98–2.1 × as long as wide, cylindrical in shape, apex rounded with long and short setae ( Fig. 67d).  Female. Body length, 18.48–26.43 mm; width, 3.69–5.46 mm.  Ovipositor and spermatheca.Ovipositor very short; styli arising terminally with short hairs ( Fig. 67e). Spermatheca distinctly curved; spermathecal gland arising near middle ( Fig. 67f).  Distribution Southern and southeastern South Australia( Fig. 98). One specimen was collected in Queenslandbut exact locality is unknown.  BiologyKnown host is  Acaciasp.Adults were collected in October to November by light trap.  Comments This species resembles  U. simulansbut differs in having body more slender in shape; the triangular mark on basal elytron vague.  Material examined    Holotype. ♂. SA:Coll. no. 5698, bearing a name label on which ‘TYPE’ was written in red ( SAM).   Paratypes. 4 ♂. SA:  3 ♂, South Australia, Australiaold collection ( SAM);  1 ♂, no locality data, Australiaold collection ( SAM).  Other material examined. 38 ♂, 3 ♀. QLD:  1 ♂, Queensland( NMV). SA:  5 ♂, Uro Bluff, W.of Lake Torrens,  2.x.1971, H.
