Description

Male. Body length, 12.62–21.6 mm; width, 1.8–3.45 mm.

Colour (Fig. 50). Body reddish brown with head, thorax and basal elytra darker. Frons with sparse white pubescence, clypeus glabrous or with very sparse white pubescence. Antennal segments 3 to 10 with yellowish fringe. Pronotal disc with 2 broad longitudinal stripes of fairly dense white pubescence; prothorax with a longitudinal stripe of very dense white pubescence on each side near ventral side. Each elytron with 2 longitudinal stripes of dense white pubescence: 1 along suture starting from base, widest at base, and becoming narrower toward apex, and 1 along margin, starting from or behind shoulder, widest at base tapering toward apex; the rest of elytra with sparse white pubescence. Body colour varies from blackish brown to reddish brown.

Head. Postclypeus subtriangular, convex, smooth and shiny; frontoclypeal suture deep and wide in middle; distance between lower lobes of eyes 1.67–1.9 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.23–1.31 × as long as distance between eyes on ventral side; genal length 0.35– 0.39 × as long as head width immediately below eyes. Antennae as long as or slightly longer than body; segments 5–10 produced on one side at apex.

Thorax and abdomen. Pronotum 1.25–1.47 × as long as width, rounded at side; posterior margin 1.15– 1.35 × as wide as anterior margin; pronotal disc weakly binodulose in middle area; disc and side strongly rugose transversely. Scutellum semicircular, with sparse pubescence. Elytra 4.25–4.78 × as long as prothorax and 4.50–4.87 × as long as shoulder width; elytra finely punctate; elytral apex strongly bispinose with spine at margin distinctly longer than that at suture. The sutural spine at the elytral apex varies from a small to long but never longer than marginal spine. Apex of terminal sternite truncate or slightly emarginate.

Male terminalia. Apices of both ventral and dorsal median lobes rounded; dorsal lobe slightly longer than ventral lobe; spined region of internal sac divided into 2 sections: first section about as long as unspined gap between first and second sections, with fairly dense multi-branched spines and scale like spines; second section shorter than first section, with sparse short simple spines ( Fig. 88a). Eighth sternite obliquely truncate at sides, shallowly emarginate at apex, with fairly long setae arising terminally; ventral surface with cloud-like processes ( Fig. 88b). Eighth tergite shallowly emarginate at apex; surface with fairly dense basally-forked spines and simple spines ( Fig. 88c). Paramere robust, 2.0–2.09 × as long as wide; apex obliquely truncate with fairly dense long and short setae ( Fig. 88d).

Female. Body length, 15.57–22.69 mm; width, 2.34–3.50 mm.

Body more robust and broader; pubescent patterns on elytra similar to those in males; antennae shorter than body, without the fringe;

Ovipositor and spermatheca. Ovipositor relatively long; styli arising terminally with short and long hairs ( Fig. 88e). Spermatheca heavily curved; spermathecal gland short, arising near base ( Fig. 88f).

Distribution

Northeastern, southern and southeastern Queensland, northern, northeastern and southeastern New South Wales, eastern and southern Victoria, southern Tasmania, southeastern South Australia, and southwestern and southeastern Western Australia ( Fig. 110).

Biology

Known hosts are Acacia armata   , and Loranthus sp.   and A. oxycedrus   . Adults were collected by light trap between September and April.

Comments

This species closely resembles U. parvus   but differs in having the body more robust and longer; elytra of both sexes with denser and longer whitish pubescence along the suture and margin, and the elytral apex with the marginal spine always distinctly longer than the sutural spine.
