Diagnostic description
Holotype, male (Fig. 65a). Length 2.48 mm. Color black; legs deep ferruginous to black; antenna lighter ferruginous. Body subovate; in dorsal aspect and in profile with constriction between pronotum and elytron. Rostrum dorsally swollen, with distinct median carina, remainder coarsely punctate with erect white scales, subapical third subglabrous, weakly punctate. Eyes medially approximate. Pronotum subglabrous, with minute punctures, in front of elytral humeri with row of deep punctures, evenly rounded towards sides. Elytra subglabrous with minute punctures; striae obsolete; basal margin straight, simple. Femora with anteroventral ridge distinct, at base abruptly ending and forming markedly projecting blunt angle; at middle with inconspicuous tooth. Mesofemur and metafemur dorsally densely squamose with white scales. Metafemur with smooth dorsoposterior edge; subapically without stridulatory patch. Aedeagus (Fig. 65b) apically subangulate; ductus ejaculatorius subapically with weak bulbus. Intraspecific variation. Length 2.30–2.88 mm. Female rostrum in apical 2/3 dorsally flattened, subglabrous, sparsely punctate; basally swollen, with erect white scales.

Distribution
Jayapura Reg. (Cyclops Mts). Elevation: 385–950 m.
Biology
Collected by beating foliage in primary forests.
Etymology
This epithet is based on the Greek prefix pseudo (false) and the name of Trigonopterus nasutus (Pascoe) which is superficially very similar and occurs sympatrically.
Notes
Trigonopterus pseudonasutus Riedel, sp. n. was coded as “Trigonopterus sp. 22” by Riedel et al. (2010)[1] and Tänzler et al. (2012)[2], respectively “Trigonopterus spv” in the EMBL/GenBank/DDBJ databases.
