42. Trigonopterus kanawiorum Riedel sp. n.

Diagnostic description.

Holotype, male (Fig. 42a). Length 2.68 mm. Color black; antenna and tarsi ferruginous. Body ovate; in dorsal aspect with weak constriction between pronotum and elytron; in profile evenly convex.

Elytra densely punctate with minute punctures, especially on intervals; strial punctures slightly larger; striae impressed as fine lines; lateral stria behind humeri simple, not deepened. Femora edentate. Mesofemur and metafemur dorsally densely squamose with silvery scales. Metafemur with denticulate dorsoposterior edge; subapically with stridulatory patch. Metatibia apically with uncus, without premucro. Abdominal ventrite 5 tomentose.
