Pronotum with disk coarsely punctate-reticulate; interspaces between punctures subglabrous; each puncture with one minute seta. Elytra with striae marked by deep punctures each with one minute seta; intervals weakly costate, subglabrous. Femora edentate; anteroventral ridges simple. Metafemur with dorsoposterior edge indistinct; subapically with stridulatory patch. Abdominal ventrites 1–2 concave, with scattered coarse punctures; ventrite 5 with broad shallow impression, with sparse small punctures. Penis (Fig. 15b) with sides of body weakly concave, converging; apex setose, with distinct median extension; basal orifice ventrally with brace; apodemes 2.4× as long as body of penis; transfer apparatus flagelliform, curved, pointing basad, ca. 2.0× as long as body of penis; ductus ejaculatorius without bulbus.

Distribution
C-Sulawesi Prov. (Mt Dako). Elevation 1900–2200 m.
Biology
On foliage in montane forest.
Etymology
This epithet is based on the combination of the Greek prefix para- (next to; near by) and the sibling species Trigonopterus moduai, sp. nov..
Notes
Trigonopterus paramoduai sp. nov. was coded as “Trigonopterus sp. 1233” and belongs to the T. arachnobas-group. It is very close to T. moduai sp. nov. (3.20–4.11% cox1 p-distance) from which it can be distinguished by the ferruginous elytral color, a slightly longer rostrum, and the shorter flagellum of the male genital.
