(Figs 43, 81, 106)

Uracanthus albatus Lea, 1916: 378 .— Lea, 1917b: 619; McKeown, 1947: 63; Duffy, 1963: 116.

Description Male. Body length, 13.37–24.56 mm; width, 2.38–5.23 mm.

Colour (Fig. 43). Body reddish brown with head, thorax and basal 1/5 of elytra often darker. Head, pronotal disc and basal 1/10 of elytra with very dense white and long pubescence; a longitudinal line, more or less glabrous, starting from frontoclypeal suture and ending near posterior margin of pronotal disc; pronotal disc with a small glabrous spot on each side of median longitudinal line; each side of pronotum with a wide longitudinal stripe of dense white pubescence near ventral side; sterna and pleura with dense yellowish white pubescence. Each elytron covered with dense short white pubescence, and 3 narrow stripes of denser pubescence on disc excluding 1 at suture and 1 at margin. Legs covered with fairy dense pubescence; 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 varies from reddish brown to yellowish brown. Specimens from Victoria differ from other specimens in having sparser pubescence.

Head. Postclypeus subtriangular and flattened, with dense coarse punctures but mostly hidden in dense pubescence; frontoclypeal suture deep and narrow in middle; distance between lower lobes of eyes 1.82–2.00 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 0.86–0.94 × as long as distance between eyes on ventral side; genal length 0.24–0.37 × as long as head width immediately below eyes. Antennae slightly longer than body; segments 4–10 flattened and produced on one side at apex.

Thorax and abdomen. Pronotum 1.14–1.25 × as long as width, with a small conical process at each side; posterior margin 1.25–1.43 × as wide as anterior margin; pronotal disc weakly binodulose in middle area; disc and side strongly rugose transversely throughout. Scutellum semicircular, with dense pubescence. Elytra 4.07–4.56 × as long as prothorax and 3.34–4.07 × as long as shoulder width; each elytron with 3 longitudinal carinae on disc; apex distinctly bispinose, with sutural spine usually longer. Apex of terminal sternite more or less truncate.

Male terminalia. Apices of ventral and dorsal median lobes rounded; ventral lobe slightly shorter than or as long as dorsal lobe; spined region of internal sac divided into two sections: first section with mixture of dense simple spines and multi-branched spines along side areas; second section with sparse short simple spines ( Fig. 81a). Eighth sternite strongly obliquely truncate at sides, widely and deeply emarginate at apex, with long setae arising terminally; ventral surface with dense cloud-like processes ( Fig. 81b). Eighth tergite truncate or slightly emarginate at apex, with some short simple spines and multi-branched spines on mid area ( Fig. 81c). Paramere 1.46–1.48 × as long as wide, cylindrical in shape; apex rounded with long and short setae ( Fig. 81d).

Female. Body length, 17.21–26.55 mm; width, 4.27–5.43 mm.

Antennae and legs shorter; abdomen more robust; femora without brownish brush-like hairs and visible sternites without medial tufts of very dense brownish hairs.

Ovipositor and spermatheca. Ovipositor short; styli arising terminally with short hairs ( Fig. 81e). Spermatheca slightly curved; spermathecal gland arising at base ( Fig. 81f).

Distribution

Widely distributed in southern and southeastern Queensland, northeastern New South Wales, Victoria, northern, eastern and southeastern South Australia, and southern Western Australia ( Fig. 106).

Biology

Known hosts are Grevillea huegelii and Acacia sp. and A. sowdenii . Adults were collected from July to December and February to March, by MV light trap.

Comments

This species resembles U. ventralis but differs in having the apex of the elytra distinctly bispinose; head, pronotal disc and basal 1/10 of the elytra with pubescence distinctly denser, whiter and longer than that on the remaining parts, and each elytron with only 3 longitudinal stripes of dense pubescence on the disc.
