Diagnostic description

Holotype, male (Fig. 17a). Length 4.16 mm. Color of antennae and tarsi dark ferruginous; remainder black with slightly bronze luster. Body subovate; in dorsal aspect with distinct constriction between pronotum and elytron; in profile dorsally convex. Rostrum dorsally with median and pair of submedian ridges, converging on forehead; intervening furrows each with sparse row of suberect piliform scales; epistome indistinct, sparsely punctate. Pronotum with sides weakly converging in straight line to distinct subapical constriction; disk densely coarsely punctate-reticulate, medially costate; with sparse recumbent narrow scales. Elytra with striae marked by weakly impressed lines and sparse coarse punctures; sutural interval and humerus densely punctate, intervals 2–7 each with single row of punctures; with scattered recumbent narrow scales. Profemur with anteroventral ridge simple, ending with small blunt tooth. Meso- and metafemur with anteroventral ridge crenate, ending with small acute tooth; anterior surface densely punctate, each puncture with recumbent narrow scale. Metafemur with dorsoposterior edge weakly crenate; subapically with stridulatory patch. Metatibia with posterior face subglabrous, with sparse setae, possibly partly abraded. Abdominal ventrites 1–2 medially concave, subglabrous; sublaterally with suberect scales; ventrite 5 flat, coarsely punctate, with dense erect setae. Penis (Fig. 17b) with sides of body subparallel, at middle and subapically with constriction; apex subangulate; sparsely setose; apodemes 2.2 × as long as body; transfer apparatus flagelliform, 1.4 × longer than body of penis; ductus ejaculatorius basally sclerotized, with distinct bulbus. Intraspecific variation. Length 4.08–4.40 mm. Female rostrum slender, in apical 1/2 median and pair of submedian costae dorsally somewhat flattened. Posterior face of metatibia in specimens from Pc. Palopo covered with yellowish setae.

Sampuna, 02°56.545'S 120°05.595'E, 1101 m, sifted, 29-V-2012.

Distribution

S-Sulawesi Prov. (Tanah Toraja, Pc. Palopo). Elevation 1100–1420 m.

Biology

In leaf litter of montane forest.

Etymology

This epithet is based on the Latin adjective collaris (pertaining to the neck) and refers to the species´ subapically constricted pronotum.

Notes

Trigonopterus collaris Riedel, sp. n. was coded as “Trigonopterus sp. 384”. This species is closely related to Trigonopterus paracollaris Riedel, sp. n., from which it can be distinguished by the elytral sculpture and the morphology of the male genitalia.
