Diagnostic description

Holotype (Fig. 30a). Length 2.43 mm. Color ferruginous; integument partly covered with brown or white scales, largely abraded. Body subovate; with weak constriction between pronotum and elytron; in profile evenly convex. Rostrum in apical half with submedian rows of punctures, sparsely covered with white scales. Eyes large, in subdorsal position. Forehead punctate, covered with brown scales. Pronotum coarsely punctate, covered with scales inserting at punctures, interspaces polished; disk clothed with brown scales, laterally and subapically with white scales. Elytra with striae deeply incised, narrow; intervals flat, each with two rows of scales largely covering surface, sutural interval with only one row; abraded scales leaving small punctures at point of insertion; subbasally and subapically clothed with white scales, remainder with brown scales and sparse white scales. Legs. Left foreleg broken off and missing; largely covered with white scales except subglabrous posterior face of meso- and metafemur and where abraded. Profemur with anteroventral ridge basally abruptly ending forming blunt angle; with subovate, slightly concave subbasal callus. Tibial apex with uncus, without premucro. Abdominal ventrites 1-2 medially flat. Terminalia (Fig. 30b). Male (ARC3663, Fig. 30e). Male rostrum with median ridge and pair of submedian ridges; covered with white scales. Abdominal ventrites 1-2 laterally swollen, medially concave. Penis (Fig. 30f) with sides of body slightly diverging to widened, rounded apex; transfer apparatus simple, spiniform, supported by single Y-shaped sclerite; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.32–2.53 mm. One specimen (ARC3666) with conspicuous pair of protrusions behind eyes, apparently a rare aberration.

Enterprise, S27°33', E153°28', Blackbutt #1, 90 m, 09-I-2002, sweeping 50934.

Distribution

Queensland: North Stradbroke Island.

Biology

Beaten from foliage of undergrowth in relatively dry forest.

Notes

Lea (1928)[1] stated in his description that the “type” was a “unique” specimen, and it therefore has to be regarded as the holotype. Regarding the distinction of this species from Trigonopterus squamosus (Lea), see the remarks above.
