Trigonopterus dentirostris Riedel sp. n. Diagnostic description. Holotype, male (Fig. 22a). Length 1.65 mm. Color black; antenna and tarsi ferruginous. Body subovate; in dorsal aspect without constriction between pronotum and elytron; in profile with distinct constriction. Rostrum at base with median ridge and pair of submedian ridges; at middle with anteriorly hollowed protuberance dorsally bearing pair of denticles; between protuberance and epistome relatively flat, with sparse erect scales; epistome at middle with dorsoposteriad directed horn. Pronotum punctate-rugose, each puncture containing one narrow transparent scale; medially with indistinct ridge. Elytra with striae deeply impressed; punctures large, each containing one downcurved seta; intervals weakly costate, subglabrous. Metafemur dorsoposteriorly simple, subapically without stridulatory patch. Aedeagus (Fig. 22b).

Distribution. Jayapura Reg. (Cyclops Mts). Elevation: 490-1095 m. Biology. Sifted from leaf litter in montane forest. Etymology. This epithet is based on a combination of the Latin nouns dens (tooth) and rostrum (snout) and refers to the dorsal protrusions of the rostrum. Notes.
