Uracanthus fuscocinereus White, 1855  

(Figs 31, 69, 100)

Uracanthus fuscocinereus White, 1855: 330   .– Aurivillius, 1912: 147; Lea, 1916: 384;

McKeown, 1940: 309; McKeown, 1947: 64.


Male. Body length 26.94–31.01 mm; width, 2.85–5.90 mm.

Colour (Fig. 31). Head, thorax, and basal elytra blackish brown; remaining elytra, legs, and antennal segments reddish brown; palpi and anteclypeus yellowish. Head with dense pale yellow pubescence except a glabrous subtriangular area on vertex. Pronotum with 2 wide longitudinal stripes of dense golden pubescence on each side: 1 on disc and 1 near ventral side; remaining pronotum with sparse pale pubescence. Each elytron with 4 basal glabrous marks: 1, long and narrow at margin; 1, robust at shoulder, 1, smallest, short and narrow between suture and shoulder, and 1, longest at suture starting at base and extending towards basal 1/5 of elytra; basal 1/3 of elytra with dense white pubescence; remaining elytra with golden pubescence. Meso- and metasterna with white pubescence; femora and abdomen with golden pubescence.

Head. Postclypeus triangular and convex, finely punctate; frontoclypeal suture wide and deep in middle; distance between lower lobes of eyes 1.65–1.77 × as long as distance between upper lobe of eyes; distance between upper lobes of eyes 1.05–1.10 × as long as distance between eyes on ventral side; genal length 0.50– 0.62 × as long as head width immediately below eyes. Antennae slightly shorter than body, with uniform and short pubescence; antennal segment 3 cylindrical, and segments 4–10 flattened, slightly produced on one side at apex.

Thorax and abdomen. Pronotum 1.27–1.35 × as long as width, rounded or slightly produced at side; posterior margin slightly wider than anterior margin; disc binodulose in middle area and finely punctate; disc and side strongly rugose transversely throughout. Scutellum semicircular, with dense pubescence. Elytra 4.28– 4.92 × as long as prothorax and 3.60–4.26 × as long as shoulder width; with fairly dense punctures in basal part; each elytron with 3 feeble longitudinal carinae on disc; apex widely emarginate and bispinose. Abdomen with short dense pubescence; apex of terminal sternite truncate or slightly emarginate.

Male terminalia. Apex of ventral median lobe pointed and apex of dorsal median lobe rounded; ventral lobe shorter than dorsal lobe; spined region of internal sac much longer than basal unspined region; spined region divided into two sections without unspined gap between sections: first section with mixture of dense large and long simple spines, fairly dense multi-branched spines and dense scale-like processes; second section with dense long simple spine and fairly dense short simple spines ( Fig. 69a). Eighth sternite obliquely truncate or slightly rounded at sides; apex emarginate, with fairly dense setae arising terminally; ventral surface with sparse short simple spines and cloud-like processes ( Fig. 69b). Eighth tergite almost truncate at sides, slightly emarginate at apex with long and short setae; mid area with dense simple spines and multibranched spine ( Fig. 69c). Paramere 2 × as long as wide, cylindrical in shape, apex rounded with long dense setae ( Fig. 69d).

Female. Body length, 21.32–32.13 mm; width, 3.92–6.94 mm.

Antennae and legs distinctly shorter, body broader with robust abdomen. Elytra slightly longer and wider, 3.36–3.97 × as long as shoulder width and 4.17–4.48 × as long as prothorax; apex of terminal sternite more or less truncate or slightly emarginate.

Ovipositor and spermatheca. Ovipositor relatively long; styli relatively large, arising terminally with short hairs ( Fig. 69e). Spermatheca slightly curved; spermathecal gland arising at basal 1/3 ( Fig. 69f).

Distribution Southeastern Queensland, northeastern New South Wales and southern Victoria ( Fig. 100).

Biology Hosts are unknown. Adults were collected in August and from October to December.


This species closely resembles U. quadristriolatus   sp. nov. but differs in having middle area of pronotal disc always covered with some pubescence; each elytron with 4 glabrous marks at base.
