Diagnostic description

Holotype, male (Fig. 23a). Length 2.20 mm. Color black; legs ferruginous, antenna light ferruginous. Body subglobose; in dorsal aspect with weak constriction between pronotum and elytron; in profile almost evenly convex. Rostrum with pair of sublateral furrows and pair of submedian row of punctures, each containing row of mesally directed setae; epistome simple. Pronotum with large disk and distinct lateral edges; moderately densely punctate with small setiferous punctures. Elytra converging to subangulate apex; striae distinct, marked by small punctures; intervals subglabrous, with row of minute punctures; some punctures with one minute recumbent seta. Metafemur with weakly denticulate dorsoposterior edge; subapically with stridulatory patch. Abdominal ventrites 1–2 deeply excavated. Aedeagus (Fig. 23b) with body flattened, sides subparallel, apex subangulate; apodemes ca. 3 X as long as body; transfer-apparatus spiniform; ductus ejaculatorius, without bulbus. Intraspecific variation. Length 1.68–2.43 mm. Female rostrum more slender than in males, dorsally punctures smaller.

Material examined

Holotype (SMNK): ARC1175 (EMBL # HE615803), PAPUA NEW GUINEA, Morobe Prov., Huon peninsula, Mindik, S06°27.311', E147°24.073', 1570 m, 10-X-2009. Paratypes (ARC, NAIC, SMNK, ZSM): Morobe Prov., Huon peninsula, Mindik: 5 exx, same data as holotype; 12 exx, ARC1179 (EMBL # HE615807), ARC1180 (EMBL # HE615808), S06°27.221', E147°24.185', 1670 m, 10-X-2009; 5 exx, 1450 m, 26-IV-1998; 1 ex, 1400–1550 m, 27-IV-1998.

Distribution

Morobe Prov. (Mindik). Elevation: 1450–1670 m.

Biology

Sifted from leaf litter in montane forest.

Etymology

This epithet is based on the Latin adjective discoidalis (shaped like a disk) and refers to the species´ outline when viewed from above.

Notes

Trigonopterus discoidalis Riedel, sp. n. was coded as “Trigonopterus sp. 88” by Tänzler et al. (2012)[1].
