Diagnostic description
Holotype, male (Fig. 51a). Length 3.50 mm. Color black, legs and antenna deep ferruginous. Body ovate; with weak constriction between pronotum and elytron; in profile almost evenly convex, elytral base medially weakly swollen and slightly projecting. Rostrum dorsally rugose-punctate in basal half, punctate in apical half. Pronotum densely punctate except along impunctate midline. Elytra densely punctate; strial punctures slightly larger than minute punctures on intervals; striae impressed as fine lines; lateral stria behind humeri with dense row of deep punctures. Profemur and metafemur in basal half with anteroventral ridge terminating as tooth; tooth of profemur small. Metafemur with denticulate dorsoposterior edge; with crenulate anteroventral ridge, terminating in apical 1/3 as acute tooth; subapically with stridulatory patch. Abdominal ventrite 5 with shallow impression, densely punctate, sublaterally setose. Aedeagus (Fig. 51b) with ostium somewhat retracted; with distinct, symmetrical transfer-apparatus; ductus ejaculatorius with bulbus. Intraspecific variation. Length 2.63–3.53 mm. Female rostrum basally punctate, towards apex dorsally subglabrous, with rows of small punctures. Female abdominal ventrite 5 flat, sparsely punctate.

Distribution
Jayapura Reg. (Cyclops Mts). Elevation: 1000–1510 m.
Biology

Etymology
This epithet is based on the Latin noun monticola (mountain dweller) and refers to the species´ restriction to the upper elevations of the Cyclops Mountains.
Notes. Trigonopterus monticola Riedel, sp. n. was coded as “Trigonopterus sp. 3” by Riedel et al. (2010)[1] and Tänzler et al. (2012)[2], respectively “Trigonopterus spc” in the EMBL/GenBank/DDBJ databases.
