Description

Male. Body length, 28.03–39.96 mm; width, 5.19–7.83 mm.

Colour (Fig. 34). Body blackish brown, covered with dense and thick pale or pale yellow pubescence; pronotal disc with a large longitudinal glabrous area, wider at posterior edge and becoming slightly narrower at anterior edge; punctures on basal half of elytra more or less exposed, giving an appearance of a number of small blackish dots in pubescence on basal elytra.

Head. Postclypeus subtriangular, slightly convex, sparsely and coarsely punctate; frontoclypeal suture wide and deep in middle; distance between lower lobes of eyes 1.75–2 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 0.7–0.85 × as long as distance between eyes on ventral side; genal length 0.8–0.85 × as long as head width immediately below eyes. Antennae shorter than body, segments 4–10 flattened and produced on one side at apex.

Thorax and abdomen. Pronotum 1.18–1.39 × as long as width, side rounded with a feeble process; posterior margin 1.24–1.46 × as wide as anterior margin; pronotal disc binodulose in middle area, with distinct transverse rugae throughout. Scutellum semicircular, with sparse pubescence. Elytra 4.45–4.83 x as long as prothorax and 3.67–4.01 × as long as shoulder width; basal 2/3 of elytra with coarse punctures; apex more or less truncate with 2 sharp spines. Apex of terminal sternite truncate or slightly emarginate.

Male terminalia. Apex of ventral and dorsal median lobes rounded; ventral lobe shorter than dorsal lobe; unspined region of internal sac very short: spined region divided into 2 sections: first section with dense scalelike processes near base and dense large and long simple spines in most part; second section with fairly dense multi-branched spines ( Fig. 72a). Eighth sternite obliquely truncate at sides, strongly emarginate at apex, with long and fairly long setae arising terminally ( Fig. 72b). Eighth tergite more or less truncate and slightly emarginate at apex ( Fig. 72c). Paramere short, 2.0–2.3 × as long as wide, cylindrical in shape, apex rounded with long and short setae ( Fig. 72d).

Female. Body length, 35.41–37.56 mm; width, 7.14–7.32 mm

Body more robust and broader; antennae and legs shorter; elytra 3.61–3.82 × as long as shoulder width and 4.23–4.79 × as long as prothorax; apex of terminal sternite truncate.

Ovipositor and spermatheca. Ovipositor short; styli arising terminally with sparse long and short hairs ( Fig. 72e). Spermatheca slightly curved; spermathecal gland arising at base ( Fig. 72f).

Distribution Northeastern New South Wales and southeastern Queensland ( Fig. 101).

Biology Hosts are unknown. Adults were collected during October–December.

Comments

This species was wrongly identified as females of U. insignis   by previous workers. It resembles U. insignis   but differs in having a body covered with uniform pubescence without white pubescent lines on the pronotal disc and the elytral suture not glabrous.
