Description

Male. Body length, 17.17–32.12 mm; width, 2.68–5.59 mm.

Colour (Fig. 51). Body reddish brown with head, thorax and basal elytra darker. Frons and vertex with mixture of fairly dense white and yellowish pubescence. Pronotum with 2 longitudinal stripes of very dense yellowish pubescence at each side: 1 on disc and 1 near ventral side; each side with 2 spots of very dense yellowish pubescence between above longitudinal stripes: anterior one larger than posterior one; rest of pronotum with fairly sparse to very sparse pubescence. Each elytron with two longitudinal stripes of very dense yellowish pubescence: 1 wide on disc and 1 narrow at margin; the area between the two stripes glabrous or sparsely pubescent. Body colour may be darker or paler. Specimens from Western Australia are more hairy, for example, pronotal disc between two longitudinal stripes can have fairly dense pubescence, and the area between the two longitudinal stripes of very dense pubescence on the elytron, can be densely pubescent.

Head. Postclypeus triangular, convex, with fairly dense fine punctures; frontoclypeal suture deep and wide in middle; distance between lower lobes of eyes 2.12–2.37 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.14–1.23 × as long as distance between eyes on ventral side; genal length 0.20–0.38 × as long as head width immediately below eyes. Antennae slightly shorter than body; segments 4–10 thin and slightly produced on one side at apex.

Thorax and abdomen. Pronotum 1.17–1.44 × as long as width, rounded at side; posterior margin 1.02– 1.33 × as wide as anterior margin; pronotal disc weakly binodulose in middle area; disc and side strongly rugose transversely. The transverse rugae on the pronotal disc may vary from very strong to weak. Scutellum semicircular, with sparse to faily dense pubescence. Elytra 4.20–4.89 × as long as prothorax and 4.03–4.51 × as long as shoulder width; apex emarginate or weakly bispinose. The elytral apex varies from widely emarginate to narrowly emarginate or even more or less truncate; apical spines may be well developed or reduced to the minimum. Apex of terminal sternite emarginate.

Male terminalia. Apices of both ventral and dorsal median lobes slightly pointed; dorsal lobe about as long as or slightly longer than ventral lobe; spined region of internal sac occupying most of internal sac; basal unspined region very short with 1–2 lines of large spines near base, sometimes forming an arch in shape; spined region divided into two sections; first section much longer than second section, with sparse scale-like spines, dense long simple spines; second section with sparse simple spines and multi-branched spines near the end of this section; a short unspined gap between sections ( Fig. 89a). Eighth sternite obliquely truncate at side, narrowly emarginate at apex, with fairly long setae arising terminally; ventral surface with cloud-like processes ( Fig. 89b). Eighth tergite rounded to truncate or slightly emarginate at apex, with dense simple spines or basally-forked spines on ventral surface ( Fig. 89c). Paramere 2.53–3.0 × as long as wide, subcylindrical in shape; apex rounded with fairly dense long and short setae ( Fig. 89d).

Female. Body length, 18.14–29.59 mm; width, 2.92–5.23 mm.

Body more robust, antennae distinctly shorter than body.

Ovipositor and spermatheca. Ovipositor relatively long; styli long, arising terminally with short hairs ( Fig. 89e). Spermatheca short, slightly curved; spermathecal gland arising near base ( Fig. 89f).

Distribution

Southeastern Queensland, eastern New South Wales, Australian Capital Territory, southern and western Victoria, southeastern South Australia, eastern Tasmania, and southwestern Western Australia ( Fig. 111).

Biology

Known hosts are Ulex sp. , Acacia longifolia , Pultenaea stipularis , Helichrysum ferrugineum , Cytisus scoparius , Jacksonia sp. , J. sternbergiana, Pultanea sp., and Eucalyptus sp. Adults were found feeding on Leptospermum scoparium in November and visiting Eucalyptus and Xanthorrhoea flowers.

Comments

This species is similar to U. discicollis but differs in having the pronotal disc strongly rugose transversely; the elytral apex widely emarginate to narrowly emarginate or even more or less truncate; each side of the pronotum with 2 spots of very dense yellowish pubescence.
