Uracanthus parallelus Lea, 1916

(Figs 46, 84, 108)

Uracanthus parallelus Lea, 1916: 377 .— McKeown, 1947: 65.

Description

Male. Body length, 14.22–17.94 mm; width, 2.08–3.28 mm.

Colour (Fig. 46). Body reddish brown with head thorax, femora and basal elytra often darker. Head, thorax, abdomen and elytra with dense, long, pale yellow pubescence; pronotum with a large more or less glabrous spot in the middle; elytral shoulder with a small longitudinal glabrous mark.

Head. Postclypeus subtriangular, slightly convex, with fairly dense coarse punctures; distance between lower lobes of eyes 1.66–1.80 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.00–1.09 ×as long as distance between eyes on ventral side; genal length 0.40–0.48 × as long as head width immediately below eyes. Antennae slightly shorter than body; segments 5–10 subcylindrical and slightly produced on one side at apex.

Thorax and abdomen. Pronotum 1.18–1.20 × as long as width, rounded or sligthyl produced at side; posterior margin 1.08–1.25 × as wide as anterior margin; pronotal disc without obvious nodules in middle area; disc and side smooth with transverse rugae near anterior and posterior margins. Scutellum semicircular, with dense pubescence. Elytra 4.74–4.83 ×as long as prothorax and 4.50–5.04 × as long as shoulder width; longitudinal carinae on disc not obvious; basal 1/3 of elytra with coarse punctures and the remaining 2/3 with fine punctures gradually diminishing toward apex; apex emarginate and bispinose but spines small. Apex of terminal sternite emarginate.

Male terminalia. Apex of ventral median lobe pointed and apex of dorsal lobe truncate; ventral lobe shorter than dorsal lobe; spined region of internal sac divided into two sections: first section longer than second section, with dense long simple spines in basal half and fairly dense muti-branched spines on sides in apical half; second section about as long as unspined gap between two sections, with sparse simple spines ( Fig. 84a). Eighth sternite rounded or slightly obliquely truncate at sides, shallowly emarginate at apex, with long and fairly long setae arising terminally; ventral surface with fairly dense cloud-like processes ( Fig. 84b). Eighth tergite more or less rounded at apex with a small pointed process in middle of apex; dorsal surface with very sparse multi-branched spines near base and sparse short simple spines in middle area ( Fig. 84c). Paramere 1.38–1.4 × as long as wide, subcylindrical in shape, apex rounded with sparse long and short setae ( Fig. 84d).

Female. Unknown.

Distribution Eastern Queensland ( Fig. 108).

Biology

Hosts are unknown. One specimen was found on vine scrub. Adults were collected from September to December.

Comments

This species resembles U. froggatti but differs in having the pubescence on the elytral disc more or less evenly distributed, and the elytral apex bispinose.
