Holotype, male (Fig. 75a). Length 2.73 mm. Color of antennae and legs ferruginous; remainder black. Body subovate; in profile dorsally convex. Rostrum dorsally with median and pair of submedian costae; intervening furrows with sparse rows of suberect piliform scales; epistome indistinct, subglabrous, with sparse setae. Pronotum with disk densely punctate with small punctures; interspaces between punctures subglabrous. Elytra irregularly punctate with small punctures, along basal margin with transverse row of denser punctures; some striae marked by hardly visible hairlines; intervals flat; stria 8 along humerus with seven distinct punctures. Femora with denticle. Meso- and metafemur with anteroventral ridge crenate, ending with denticle in apical 1/3. Metafemur dorsally with row of suberect, silvery scales; dorsoposterior edge crenate in apical 1/3; subapically with stridulatory patch. Metatibia ventrally with row of sparse thin setae; dorsal outline subapically weakly concave. Abdominal ventrites 1–2 concave, subglabrous; in profile ventrite 2 subangularly projecting; ventrite 5 at middle with shallow pit, laterally punctate. Penis (Fig. 75b) with sides of body subparallel; apex rounded, nude; apodemes 1.5 × as long as body of penis; transfer apparatus spiniform, directed basad in repose, surrounded by complex of supporting sclerites; ductus ejaculatorius with indistinct bulbus.

This epithet is based on the town of Rantepao, center of the Land of Toraja. It is treated as a noun in apposition.
Trigonopterus rantepao Riedel, sp. n. was coded as “Trigonopterus sp. 409”. It is closely related to Trigonopterus toraja Riedel, sp. n. from which it can be distinguished by the structure of the penis.
