Description

Male. Body length, 22.12–26.38 mm; width, 4.92–6.26 mm.

Colour (Fig. 35). Body light reddish to blackish brown. Head with dense golden pubescence. Pronotum with 2 wide longitudinal stripes of dense golden pubescence on each side: 1 on disc and 1 near ventral side; remaining pronotum almost hairless; ventral surface of prothorax with fairly dense golden pubescence. Elytra covered with dense, short golden pubescence.

Head. Postclypeus semicircular, with dense large coarse punctures; frontoclypeal suture deep and narrow in middle; distance between lower lobes of eyes 2.20–2.36 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 0.75–0.78 × as long as distance between eyes on ventral side; genal length 0.25–0.30 × as long as head width immediately below eyes. Antennae much longer than body; segments 5–10 flattened and produced on one side at apex.

Thorax and abdomen. Pronotum 0.83–0.95 × as long as width, rounded at side; posterior margin 1.27– 1.62 × as wide as anterior margin; pronotal disc smooth and weakly binodulose. Scutellum semicircular, with dense pubescence. Elytra 4.62–5.61 × as long as prothorax and 3.23–3.47 × as long as shoulder width; each elytron with 2 slightly raised longitudinal carinae on disc; basal 1/3 of elytra coarsely punctuate; apex of elytron bispinose with sutural spine significantly larger. Abdomen paralell sided; apex of terminal sternite truncate.

Male terminalia. Apex of ventral median lobe rounded; ventral lobe slightly longer than or as long as dorsal lobe; spined region of internal sac much longer than basal unspined region; spined region with dense long simple spines throughout except a short unspined terminal area ( Fig. 73a). Eighth sternite rounded at side, shallowly emarginate at apex, with long and fairly long setae arising terminally; ventral surface with simple spines and cloud-like processes ( Fig. 73b). Eighth tergite emarginate at apex, with fairly dense basally-forked spines on dorsal surface ( Fig. 73c). Paramere long, 2.8–2.9 × as long as wide, cylindrical in shape, apex rounded with long and short setae ( Fig. 73d).

Female. Body length, 29.07–32.20 mm; width, 6.66–7.23 mm.

Abdomen more robust and broader, antennae and legs shorter. Elytra longer and wider, 3.32–3.60 × as long as shoulder width and 6.03–6.55 × as long as prothorax.

Ovipositor and spermatheca. Ovipositor short; styli arising terminally with short hairs ( Fig. 73e). Spermatheca C-shaped; spermathecal gland short and arising at base ( Fig. 73f).

Distribution This species is only found in Tasmania ( Fig. 102).

Biology

Known host is hazelnut ( Corylus spp.   ). Adults were collected from December to April and attracted to light.

Comments

This species resembles U. pseudogigas   sp. nov. but differs in being a smaller size, the pronotal disc having 2 longitudinal stripes of dense pubescence and the surface of the disc being smooth; elytral apex bispinose.
