Uracanthus discicollis Lea, 1916: 373   .— McKeown, 1947: 63.

Description

Male. Body length, 13.58–25.34 mm; width, 2.52–4.93 mm.

Colour (Fig. 52). Body reddish brown to brown with head, prothorax and basal elytra darker. Head with sparse to fairly dense white or pale yellow pubescence. Pronotal disc with 2 longitudinal stripes of very dense white pubescence; each side of pronotum with a longitudinal stripe of very dense white pubescence near ventral side; the remaining pronotum glabrous or very sparsely pubescent; prosternum with fairly dense white pubescence. Each elytron with 2 longitudinal stripes of very dense whitish pubescence: 1 wide on disc near suture and 1 narrow near margin; the remaining elytra glabrous or very sparsely pubescent. Body colour varies from blackish brown to reddish brown or brown.

Head. Postclypeus triangular or subtriangular, shiny and convex, with fairly dense fine punctures; frontoclypeal suture deep and wide in middle; distance between lower lobes of eyes 1.76–2.12 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.05–1.13 × as long as distance between eyes on ventral side; genal length 0.36–0.51 × as long as head width immediately below eyes. Antennae slightly longer than body; segments 5–10 thin, subcylindrical in shape, and slightly produced on one side at apex.

Thorax and abdomen. Pronotum 1.10–1.26 × as long as width, with a conical process at each side; posterior margin 1.05–1.34 × as wide as anterior margin; pronotal disc very weakly binodulose or not nodulose in middle area; disc and side smooth and shiny, with very feeble transverse rugae near posterior margin. Scutellum semicircular, with fairly dense pubescence. Elytra 3.34–4.28 × as long as prothorax and 3.6–4.01 × as long as shoulder width; basal 1/3 of elytra coarsely punctate and the remaining 2/3 finely punctuate toward apex; elytral apex rounded at margin and spinose or processed at suture. The apical spine of the elytron varies from sharp to none. Apex of terminal sternite distinctly emarginate.

Male terminalia. Apex of ventral median lobe strongly pointed and apex of dorsal lobe rounded or broadly projected; ventral lobe shorter than dorsal lobe; spined region of internal sac not clearly divided, with dense long simple spines ( Fig. 90a). Eighth sternite obliquely truncate or even rounded at sides, very shallowly emarginate at apex, with sparse long and short setae arising terminally; ventral surface with sparse cloud-like processes ( Fig. 90b). Eighth tergite slightly point at apex, with fairly dense basally-forked spines and simple spines on ventral surface ( Fig. 90c). Paramere long, 2.0–2.09 × as long as wide, gradually tapering toward apex; apex with sparse to dense long and short setae ( Fig. 90d).

Female. Body length, 13.71–24.55 mm; width, 2.54–4.83 mm.

Body more robust, antennae shorter than body; elytra 3.81–4.42 × as long as prothorax and 3.59–3.85 × as long as shoulder width.

Ovipositor and spermatheca. Ovipositor relatively long; styli long, arising almost terminally with short hairs ( Fig. 90e). Spermatheca slightly curved; spermathecal gland arising near base ( Fig. 90f).

Distribution

Northeastern New South Wales, Australian Capital Territory, southern and central Victoria, southeastern South Australia, and southern and southwestern Western Australia ( Fig. 112).

Biology

Hosts are unknown. Adults visit flowers of Melaleuca sp.   Adults were collected by light trap between October and January.

Comments

This species resembles U. bivitta   but differs in having the pronotal disc mostly smooth and shiny; the elytral apex rounded or with a sharp spine or process at the suture; each side of the pronotum without 2 spots of very dense yellowish pubescence.
