Diagnostic description

Male (ARC3695; Fig. 2e). Length 2.73 mm. Color black. Body subovate, almost without constriction between pronotum and elytron; in profile evenly convex. Rostrum with median costa and pair of submedian costae; intervening furrows with rows of partly abraded scales; apical 1/3 rugose-punctate. Eyes with dorsal margin bordered by furrow. Forehead sparsely punctate. Pronotum with disk subglabrous, with minute punctures; sides foveate; interspaces not microreticulate; base medially hardly extended towards elytral suture. Elytra subglabrous, striae marked by very shallow lines, without punctures; along base and humeri with row of large punctures; apex with scattered shallow punctures. Legs. Femora microreticulate, punctate. Metafemur dorsally with elongate patch of dense silvery scales; posterior surface with pair of longitudinal furrows containing rows of scales parallel to ventral and dorsal edge; dorsoposterior edge distinct. Mesotibia apically with widened uncus only, premucro absent. Metatibia apically with uncus only, premucro not visible in lateral aspect, possibly transformed into small process on posterior tibial face near tarsal insertion. Abdominal ventrite 2 swollen, posterior edge projecting and with submedian pair of denticles, medially forming shallow cavity with ventrite 1; ventrite 5 dull, microreticulate, punctate, with transversely ovate cavity. Penis (Fig. 2f) with sides of body subparallel; apex with distinct median triangular extension; transfer apparatus long, spiniform, apically bordered by pair of L-shaped sclerites; ductus ejaculatorius without bulbus. Female lectotype (Fig. 2a–d). As male except: length 2.63 mm. Rostrum dorsally subglabrous, densely punctate with small punctures. Abdominal ventrites 1 and 2 medially flat; posterior edge of ventrite 2 simple, without pair of denticles; abdominal ventrite 5 flat. Intraspecific variation. Length 2.26–2.73 mm. Mesotibia apically with large uncus and much smaller premucro.

Cook, S15°30', E145°16', 13-X-1980.

Distribution

Queensland: Cooktown.

Biology

Beaten from foliage in rainforest.

Notes

Lea (1913)[3] did not designate a holotype in the original description, which is based on three syntypes. One syntype labelled “type” could be examined and is here designated as lectotype. The species appears to be confined to the Cooktown area. Numerous specimens from other localities of coastal Queensland, including some identified as Trigonopterus albidosparsa by Lea, belong to different, closely related species.
