Holotype, male (Fig. 21a). Length 3.27 mm. Color black; legs deep ferruginous, antenna light ferruginous. Body ovate; with weak constriction between pronotum and elytron; in profile evenly convex. Rostrum dorsally densely rugose-punctate, in basal half with brown erect scales, in apical half sparsely setose. Eyes large. Pronotum densely punctate with subtriangular, setiferous punctures. Elytral striae distinct, marked by regular rows of small punctures; intervals with row of minute punctures; laterally behind humeri with ridge bordered by row of deep punctures of stria 8. Legs squamose with inconspicuous brownish scales. Femora with anteroventral ridge terminating in apical third. Metafemur with weakly denticulate dorsoposterior edge; subapically with stridulatory patch. Abdominal ventrite 5 at middle with shallow, subquadrate impression. Aedeagus (Fig. 21b) with apex subangulate; transfer-apparatus flagelliform, longer than body of aedeagus; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.67–3.27 mm. Female rostrum in apical half with relatively small, sparse punctures. Abdominal ventrite 5 simple.

Trigonopterus cyclopensis Riedel, sp. n. was coded as “Trigonopterus sp. 5” by Riedel et al. (2010) and Tänzler et al. (2012), respectively “Trigonopterus spe” in the EMBL/GenBank/DDBJ databases.
