Description

Male. Body length, 15.26–22.93 mm; width, 2.98–4.5 mm.

Colour (Fig. 45). Body reddish brown with head, prothorax and basal 1/3 of elytra often darker. Head with fairly dense yellowish pubescence. Pronotal disc with 4 longitudinal stripes of yellowish pubescence: 2 wider and denser ones on sides and 2 narrower and sparser ones between the former; each side of pronotum with a longitudinal stripe of dense pubescence near ventral side; ventral surface of prothorax with fairly dense white pubescence. Each elytron with 4 longitudinal stripes of dense yellowish white pubescence; the two closer to suture appearing to merge into one from basal 1/3 or middle to apex. Mid and hind femora with very dense, brush-like brownish hairs on ventral side. Abdomen with fairly dense yellowish pubescence; each of visible sternites 1–3 with a medial tuft of very dense brownish hairs. Body colour may vary from reddish brown to blackish. Pubescence colour may vary from whitish to greyish. Specimens from Queensland are darker than those from New South Wales.

Head. Postclypeus semicircular to subtriangular and flattened, with fine punctures; frontoclypeal suture deep and narrow in middle; distance between lower lobes of eyes 2.06–2.21 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 0.77–0.85 × as long as distance between eyes on ventral side; genal length 0.31–0.41 × as long as head width immediately below eyes. Antennae slightly shorter than body; segments 4–10 slightly produced on one side at apex.

Thorax and abdomen. Pronotum 1.12–1.30 × as long as width, with a strongly raised conical process at each side; posterior margin 1.17–1.44 × as wide as anterior margin; pronotal disc weakly binodulose in middle area; disc and side strongly rugose transversely. Scutellum semicircular, with dense pubescence. Elytra 3.87– 4.61 × as long as prothorax and 3.64–4.05 × as long as shoulder width, with coarse punctures in basal 1/3, gradually diminishing toward apex; apex bispinose with marginal spine much longer. The apical spines of elytra may vary from long to short. Apex of terminal sternite slightly emarginate.

Male terminalia. Apex of ventral median lobe emarginate and apex of dorsal lobe narrowly rounded or slightly pointed; ventral lobe longer than dorsal lobe; spined region of internal sac divided into two sections: first section longer than unspined gap between first and second sections, with fairly dense short simple spines; second section about as long as first section, with sparse short simple spines ( Fig. 83a). Eighth sternite obliquely truncate or more or less rounded at side, clearly emarginate at apex, with sparse long setae arising terminally; ventral surface with cloud-like processes ( Fig. 83b). Eighth tergite shallowly emarginate at apex; dorsal surface with fairly dense short simple spines and multi-branched spines in basal area ( Fig. 83c). Paramere 1.96–1.98 × as long as wide, cylindrical in shape, apex rounded with long and short setae ( Fig. 83d).

Female. Body length, 19.82–22.19 mm; width, 3.56–4.63 mm.

Antennae distinctly shorter than body; femora without brownish brush-like hairs and visible sternites without medial tufts of very dense brownish hairs.

Ovipositor and spermatheca. Ovipositor relatively long; styli arising terminally with short and long hairs ( Fig. 83e). Spermatheca curved, particularly near apex; spermathecal gland short and arising at basal 1/3 ( Fig. 83f)

Distribution

Northeastern and southeastern Queensland, eastern New South Wales, southern and central Victoria, northern South Australia, and southwestern Western Australia ( Fig. 107). This species was accidentally introduced to Ecuador ( Monné 2005).

Biology

Known hosts are Acacia spp , Helichrysum ferrugineum , Melaleuca uncinata and Casuarina sp. Adults were collected from October to April, and attracted to light.

Comments

This species resembles U. albatus but differs in having the pronotal disc with 4 longitudinal stripes of pubescence on the disc; pubescent stripes close to the elytral suture tending to merge from middle towards the apex.
