(Figs 20, 59, 94)

Description

Male. Body length, 18.28–30.36 mm; width, 3.14–6.23 mm.

Colour (Fig. 20). Head, thorax, basal 2/5 and apical 1/10 of elytra dark reddish brown to blackish brown; antennae, legs and the remaining part of elytra reddish brown. Frons and clypeus with mixed dense golden and white pubescence; vertex with dense white pubescence except a V-shaped glabrous area extending from medial frontal groove to posterior edge of vertex. Pronotum with fairly dense pale yellow pubescence; 2 longitudinal stripes of dense white pubescence on each side: 1 on disc and 1 near ventral side. Each elytron with a subtriangular glabrous mark extending from shoulder to basal 1/3, and margined with a line of dense white pubescence; some areas of the mark sometimes covered with sparse white pubescence; apical area with sparse white pubescence margined with a narrow line of dense white pubescence; the remaining part of elytral disc with pubescence of different density, giving an appearance of clustered denser pubescence among less dense pubescence. The subtriangular mark on elytra may be reduced or expanded. The body may vary from dark brown to brown. Longitudinal pubescent stripes on pronotal disc are sometimes absent from the posterior margin.

Head. Postclypeus semicircular and slightly convex, with dense large coarse punctures; frontoclypeal suture deep and narrow in middle; median frontal groove narrow and deep, terminating near posterior edge of vertex; distance between lower lobes of eyes 1.7–1.75 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 2.3–2.38 × as long as distance between eyes on ventral side; genal length 0.34–0.36 × as long as head width immediately below eyes. Antennae slightly shorter than body; segments 5– 10 flattened and produced on one side at apex.

Thorax and abdomen. Pronotum 1.15–1.55 × as long as width, rounded with a very feeble process at each side; posterior margin 1.10–1.33 × as wide as anterior margin; pronotal disc binodulose in middle, and rugose transversely near anterior and posterior margins. Scutellum semicircular, with dense pubescence. Elytra 3.95– 4.48 × as long as prothorax and 3.38–4.07 × as long as shoulder width; each elytron with 3 very feeble longitudinal carinae; basal elytra finely punctate; apex widely emarginate and bispinose. Abdomen slender, apex of terminal sternite notched.

Male terminalia. Apex of ventral median lobe more or less rounded with a very shallow notch and apex of dorsal lobe rounded; ventral lobe longer than dorsal lobe; spined region of internal sac 4.9–5.2 × as long as basal unspined region; spined region divided into 2 sections with an unspined gap between sections: first section bearing dense long simple spines with fairly dense multi-branched spines near sides; second section with sparse simple spines ( Fig. 59a). Eighth sternite ( Fig. 59b) strongly obliquely truncate at sides, shallowly emarginate at apex, with long and fairly long setae arising terminally; ventral surface with multi-branched spines and cloud-like processes. Eighth tergite ( Fig. 59c) emarginate at apex, with dense short simple spines and multi- branched spines on dorsal surface. Paramere 1.75–1.84 × as long as wide, cylindrical in shape; apex rounded with long and short setae ( Fig. 59d).

Female. Body length, 15.99–29.39 mm; width, 2.93–6.03 mm.

Similar to male but differs in having shorter antennae and legs and more robust abdomen; apex of terminal sternite rounded; elytra 3.16–3.95 × as long as shoulder width and 4.17–4.90 × as long as prothorax.

Ovipositor and spermatheca. Ovipositor short; styli arising terminally with short hairs ( Fig. 59e). Spermatheca heavily curved; spermathecal gland long and arising near base ( Fig. 59f).

Distribution Southern, southeastern and western coastal regions of Australia and central Australia ( Fig. 94).

Biology

Recorded host plants for this species are Acacia coriacea , Aster ramulosus , Cassinia sp. , Citrus sp. , Correa speciosa var mormalis , Eriostemon lanceolatus , Helichrysum ferrugineum and Olearia ramulosa . Adults were collected from June to February.

Comments

This new species was described as a variant (Var. B) of U. triangularis by Lea (1916). However, after having carefully examined all specimens available, we believe that it should be a new species. This new species resembles U. triangularis but differs in having more uneven pubescence; the subtriangular mark and apical areas on the elytra covered with pubescence; the apex of ventral lobe of aedeagus much longer than dorsal lobe, apex of ventral lobe more or less pointed; apex of eighth tergite emarginate and ventral surface of eighth sternite with simple spines.
