Description

Male. Body length, 24.17–38.73 mm; width, 4.15–7.47 mm.

Colour (Fig. 30). Body reddish brown to blackish brown with head, prothorax, basal and marginal elytra, and legs often darker. Body covered with dense golden pubescence. Pronotal disc with 4 narrow longitudinal stripes of dense golden pubescence; each side with a wide longitudinal stripe of dense pubescence near ventral side. Each elytron with a very vague subtriangular basal mark covered with short golden pubescence and obvious darker than other part, without any margin; remaining elytron covered with very dense golden pubescence, arranged in 4 longitudinal lines. Body colour may vary from reddish brown to blackish brown; pubescence on the basal mark of the elytron varies from very sparse to dense.

Head. Postclypeus semicircular, slightly convex, finely punctate; frontoclypeal suture wide and deep in middle; distance between lower lobes of eyes 1.35–1.55 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.17–1.36 × as long as distance between eyes on ventral side; genal length 0.55–0.63 × as long as head width immediately below eyes. Antennae slightly shorter than body, with dense short pubescence; segments 5–10 flattened, and produced on one side at apex.

Thorax and abdomen. Pronotum 1.27–1.45 × as long as wide, rounded at side; pronotal disc binodulose in middle area and finely punctate; disc and side distinctly rugose transversely. Scutellum semicircular, with dense pubescence. Elytra 4.01–4.70 × as long as prothorax and 3.79–4.11 × as long as shoulder width; each elytron with 3 feeble longitudinal carinae; basal elytra with fairly dense punctures; apex bispinose. Abdomen with dense pubescence; apex of terminal sternite truncate.

Male terminalia. Apex of ventral median lobe widely emarginate, dorsal median lobe rounded; dorsal lobe shorter than ventral lobe; spined region of internal sac about 3 × as long as basal unspined regions; spined region divided into 2 sections; first section with mixture of dense large and long simple spines and fairly dense multi-branched spines; second section with fairly dense simple spines ( Fig. 68a). Eighth sternite obliquely truncate at terminal sides, strongly emarginate at middle area with long and fairly long setae arising terminally; ventral surface with sparse basally-forked spines in middle and sparse simple spines near sides ( Fig. 68b). Eighth tergite almost truncate at apex, basal area with simple spines ( Fig. 68c). Paramere 1.82–1.85 × as long as wide, cylindrical in shape, apex rounded with long and short setae ( Fig. 68d).

Female. Body length, 32.33–43.79 mm; width, 5.72–8.56 mm.

Antennae and legs distinctly shorter and body more robust; elytra 3.83–4.15 × as long as shoulder width and 4.00–4.87 × as long as prothorax; apex of terminal sternite truncate or slightly emarginate.

Ovipositor and spermatheca. Ovipositor short; styli arising laterally with both long and short hairs ( Fig. 68e). Spermatheca heavily curved and C-shaped; spermathecal gland very long and arising at basal 1/3 ( Fig. 68f).

Distribution

Eastern and northeastern New South Wales and southeastern Queensland ( Fig. 99). One specimen was collected in Western Australia but exact locality is unknown.

Biology

Host plants are orange, native finger lime ( Citrus australasica ), mandarin orange, and lychee. Eggs and larvae were found in the smaller branches of citrus trees. Adults were collected in January, July, August, and during September to December and attracted to MV light.

Comments

This species differs from other species of Uracanthus in having the pronotal disc and each elytron covered with very dense long pubescence, arranged in four longitudinal lines.
