Holotype, male (Fig. 78a). Length 2.15 mm. Color black, with bronze lustre; legs and antenna ferruginous. Body subovate; in dorsal aspect without constriction between pronotum and elytron; in profile with distinct constriction. Rostrum with weak median ridge and pair of submedian furrows. Pronotum anteriorly densely punctate, with yellowish elongate apicad directed scales; disk subglabrous, with sparse minute punctures. Elytra near base and before apex with sparse, yellowish, elongate scales; remainder subglabrous, with sparse minute punctures; striae obsolete. Anteroventral ridges of femora simple. Metafemur with weakly denticulate dorsoposterior edge, subapically without stridulatory patch. Abdominal ventrite 5 swollen, at middle with depression. Aedeagus (Fig. 78b) with apex rounded; behind orifice containing X-shaped pair of sclerites; in profile dorsal contour convex; transfer apparatus spiniform, 0.3× as long as body of aedeagus. Intraspecific variation. Length 2.15–2.30 mm. Female rostrum slender, dorsally subglabrous, sparsely punctate.

This epithet is based on the Latin adjective simulans (imitating). It refers to the close resemblance of this species with other closely related ones.
Trigonopterus simulans Riedel, sp. n. was coded as “Trigonopterus sp. 45” by Riedel et al. (2010) and Tänzler et al. (2012), respectively “Trigonopterus spas” in the EMBL/GenBank/DDBJ databases.
