Diagnostic description

Holotype, male (Fig. 99a). Length 2.78 mm. Color of antennae and tarsi ferruginous; remainder black. Body subovate; in dorsal aspect with weak constriction between pronotum and elytron, in profile dorsally convex. Rostrum dorsally with median carina and pair of submedian ridges; intervening furrows with rows of yellowish piliform scales; in profile forming rounded hump at junction with forehead; epistome indistinct, subglabrous. Pronotum with disk densely punctate with small punctures; interspaces between punctures subglabrous; median line impunctate. Elytra densely irregularly punctate with small punctures; some striae marked by hardly visible hairlines; intervals flat; stria 8 along humerus with row of six large punctures. Femora edentate. Meso- and metafemur with anteroventral ridge crenate; anterior surface of femora densely punctate, each puncture with narrow recumbent scale. Metafemur dorsally with row of coarse punctures and sparse row of subrecumbent silvery scales; subapically with stridulatory patch. Metatibia with dorsal edge in basal 1/2 weakly crenate, in apical 1/3 narrowed, concave. Abdominal ventrite 1 and anterior portion of ventrite 2 concave, subglabrous; ventrite 5 at middle impressed, concave, sparsely punctate, sublaterally and subapically densely punctate with sparse suberect scales. Penis (Fig. 99b) with sides subparallel; apex subangular, weakly pointed, without setae; apodemes 2.0 × as long as body of penis; transfer apparatus spiniform, directed basad in repose; ductus ejaculatorius with distinct, swollen bulbus. Intraspecific variation. Length 2.48–3.03 mm. Female body more slender. Female rostrum slender, from basal hump bent ventrad, almost straight; dorsally subglabrous, with two submedian rows of punctures, with pair of sublateral furrows. Female abdominal ventrite 5 flat, sparsely punctate.

Distribution

C-Sulawesi Prov. (Lake Poso). Elevation 950–1080 m.

Biology

On foliage in montane forests.

Etymology

This epithet is the Latin adjective vicinus, -a, -um (neighboring, similar) and refers to its sibling species found in close geographical distance.

Notes

Trigonopterus vicinus Riedel, sp. n. was coded as “Trigonopterus sp. 412”. It is closely related to Trigonopterus ejaculatorius Riedel, sp. n. from which it differs by 17.3% p-distance of cox1 and can be distinguished by the less marked basal hump of the rostral profile.
