Elytra with striae marked by deep punctures each with one minute seta; intervals costate, subglabrous, with few interspersed punctures. Femora edentate; anteroventral ridges simple. Metafemur with dorsoposterior edge indistinct; subapically with stridulatory patch. Abdominal ventrites 1–2 concave, microreticulate, with coarse punctures; ventrite 5 with broad, shallow impression, microreticulate, with sparse small punctures. Penis (Fig. 13b) with sides of body subparallel, weakly converging, subapically with shallow constriction; apex setose, with median rounded extension; basal orifice ventrally with brace; apodemes 2.2× as long as body of penis; transfer apparatus flagelliform, looping S-shaped apicad, its tip emerging from apical orifice, ca. 3.5× as long as body of penis; ductus ejaculatorius without bulbus.

Notes
Trigonopterus moduai, sp. nov. was coded as “Trigonopterus sp. 1201” and belongs to the T. arachnobas-group. It is very close to T. paramoduai sp. nov. (3.20–4.11% cox1 p-distance) but can be distinguished by the darker elytral color, a slightly shorter rostrum, and the much longer flagellum of the male genital.
