Holotype, male (Fig. 63a). Length 2.18 mm. Color black; antenna ferruginous. Body slender, ovate; without constriction between pronotum and elytron; in profile evenly convex. Rostrum in apical half smooth; in basal half with two pairs of longitudinal furrows containing sparse scales; above eye simple. Eyes with dorsal margin continuous with head, not carinate. Pronotum subglabrous, sparsely punctate with minute punctures. Elytra subglabrous, striae hardly visible but each with a deep pit along basal margin. Femora subglabrous; metafemur dorsally with silvery scales (partly abraded). Metafemur on posterior surface with longitudinal impression and row of scales; with smooth dorsoposterior edge; subapically without stridulatory patch. Mesotibia basally with external angulation, subapically simple, with uncus. Metatibia subapically simple, with uncus and few recumbent setae. Abdominal ventrite 5 with median impression. Aedeagus (Fig. 63b). Apex asymmetrical, with angular extension shifted to the right; laterally with dense brushes of weakly curved setae; proximal part of ductus ejaculatorius parallel to axis of aedeagus, enclosed by sclerites of transfer apparatus; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.18–2.51 mm. Female abdominal ventrite 5 flat.

This epithet is based on a combination of the name of Trigonopterus politus (Faust) and the Greek suffix eides (similar) and refers to their superficial similarity.
Trigonopterus politoides Riedel, sp. n. was coded as “Trigonopterus sp. 25” by Riedel et al. (2010) and Tänzler et al. (2012), respectively “Trigonopterus spy” in the EMBL/GenBank/DDBJ databases.
