Description Male. Body length , 13.99–15.58 mm ; width, 2.21–2.58 mm . Colour (Fig. 48). Head, thorax, antennae, and basal 1/3 elytra reddish brown to blackish brown, and remaining elytra yellowish brown. Body covered with fairly dense pale yellow pubescence. Each elytron usually with a wide submarginal longitudinal glabrous mark starting from shoulder extending to basal 1/3–apical 1/3 of elytra. The submarginal longitudinal glabrous mark on the elytra varies from very clear to almost completely absent. Head. Postclypeus triangular, convex, smooth, shiny and glabrous; frontoclypeal suture deep and narrow in middle; distance between lower lobes of eyes 1.58–1.76 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 1.44–1.50 × as long as distance between eyes on ventral side; genal length 0.26–0.34 × as long as head width immediately below eyes. Antennae as long as or slightly longer than body; segments 4–10 thin, subcylindrical in shape, and slightly produced on one side at apex. Thorax and abdomen . Pronotum 1.25–1.48 × as long as width, rounded at sides; posterior margin 1.10– 1.21 × as wide as anterior margin; pronotal disc without obvious nodulose area in middle; disc and side smooth with feeble transverse rugae near posterior margin. Scutellum semicircular, with dense pubescence. Elytra 3.70–3.89 × as long as prothorax and 4.19–4.53 × as long as shoulder width; basal 1/3 of elytra with fine puncture, diminishing toward apex; apex truncate or slightly marginate with a small tooth at suture and margin, respectively. Apex of terminal sternite rounded or widely truncate. Male terminalia . Apex of ventral median lobe and apex of dorsal lobe slightly pointed or widely rounded; ventral lobe shorter than dorsal lobe; spined region of internal sac about 3 × as long as terminal unspined area, with dense long simple spines ( Fig. 86a ). Eighth sternite rounded or obliquely truncate at sides, shallowly emarginate at apex, with some setae arising terminally; ventral surface with simple spines ( Fig. 86b ). Eighth tergite rounded or very weakly emarginate at apex; dorsal surface with fairly dense basally-forked spines on basal-mid area ( Fig. 86c ). Paramere 2.8–2.9 × as long as wide, cylindrical in shape, apex rounded with long and short setae ( Fig. 86d ). Female. Body length, 11.11–17.50 mm ; width, 2.0– 2.90 mm Body more robust; antennae shorter than body; elytra 4.23–4.53 × as long as prothorax and 4.06–4.39 ×as long as shoulder width. Ovipositor and spermatheca. Ovipositor relatively long; styli arising terminally with short hairs ( Fig. 86e). Spermatheca heavily curved, particularly near base; spermathecal gland arising at base ( Fig. 86f ). Distribution Northern and eastern Queensland ( Fig. 108 ). Biology Hosts are unknown. Adults were collected during October to December. Comments This species resembles U. parallelus but differs in having each elytron with a wide submarginal longitudinal glabrous mark starting from the shoulder and extending to 1/3–2/3 of elytral length; the elytral apex more or less truncate. The label of the holotype states that the specimen is a male but it is in fact a female. Material examined Holotype . 1 ♀ . Northern Queensland , Coll no.
