Diagnostic description

Lectotype (Fig. 20a, c). Length 2.30 mm. Color black, legs and antenna dark ferruginous. Body subovate, with constriction between pronotum and elytron; in profile with shallow constriction. Rostrum with median ridge and pair of submedian ridges; intervening furrows with rows of white scales; apical 1/3 rugose-punctate. Eyes large, in dorsal position. Pronotum with disk punctate; sides more densely punctate with slightly larger punctures. Elytra subglabrous; along base and humeri with row of large punctures; subapically with sparse small punctures. Legs. Meso- and metafemur dorsally with narrow band of white scales; anteroventral ridge of femora weakly crenulate, terminating 1/3 before apex with minute denticle. Tibial apex with uncus, without premucro. Abdominal ventrite 2 posteriorly forming edge; medially forming common cavity with ventrite 1; ventrite 5 weakly concave, almost flat, nude, microreticulate, sparsely punctate. Penis (Fig. 20b) with sides of body subparallel; apex broadly subangulate; body containing two pairs of lyriform sclerites; transfer apparatus short, dentiform; ductus ejaculatorius near insertion to transfer apparatus swollen, subapically with very indistinct bulbus. Intraspecific variation. Length 1.96–2.30 mm. Female rostrum subglabrous, with submedian rows of punctures. Female abdominal ventrites 1 and 2 convex, medially flat.

Distribution

Biology

Beaten from foliage in rainforest.

Notes

Lea (1913)[2] did not designate a holotype in the original description nor specify the number of specimens examined. The original description is based on more than one specimen. One pair with the male marked “TY” and one syntype from Sue Island could be examined, but other specimens may exist. The male is here designated as lectotype.
