Diagnostic description

Holotype, male (Fig. 64a). Length 2.60 mm. Color of antennae ferruginous; legs dark ferruginous; remainder black. Body subovate; in dorsal aspect with moderate constriction between pronotum and elytron; in profile dorsally convex. Rostrum dorsally with median and pair of submedian ridges; intervening furrows each with sparse row of erect scales; epistome scabrous, with median ridge. Pronotum with disk densely punctate with coarse, almost confluent punctures; each puncture containing single, minute seta; narrow interspaces subglabrous; medially with indistinct costa. Elytra densely irregularly punctate with small punctures; striae indistinct; interspaces between punctures subglabrous; striae 7–9 with larger punctures; stria 8 along humerus with seven large, coarse punctures. Femora edentate; anterior surface densely coarsely punctate, each puncture with suberect scale. Metafemur with dorsoposterior edge simple; subapically with stridulatory patch. Abdominal ventrites 1–2 concave, subglabrous, with sparse coarse punctures; in profile ventrite 2 rounded; ventrite 5 at middle with shallow impression, densely coarsely punctate, sublaterally with sparse erect scales. Penis (Fig. 64b) with sides of body diverging; apex bent ventrad, subangulate, with short subacute median extension, with sparse setae; apodemes 2.8 × as long as body; transfer apparatus complex, with basal sclerites and flagelliform part, subequal to body of penis; ductus ejaculatorius with distinct bulbus. Intraspecific variation. Length 2.60–2.78 mm. Female rostrum slender, dorsally with median and pair of submedian glabrous costae; epistome simple, punctate-rugose. Female abdominal ventrites 1–2 almost flat.

Biology

On foliage in lower montane forests.

Distribution

C-Sulawesi Prov. (Pendolo, Tentena). Elevation 680–1245 m.

Etymology

This epithet is a Latinized adjective that refers to Lake Poso which is close to the type locality.

Notes

Trigonopterus posoensis Riedel, sp. n. was coded as “Trigonopterus sp. 377”. This species is very closely related to Trigonopterus obelix Riedel, sp. n., from which it differs by ca. 15.0–15.5% p-distance of cox1, and by the subangularly projecting profile of abdominal ventrite 2.
