Material examined
Holotype (SMNS): ARC7267 (GenBank # OP078708), E-Malaysia, Sarawak, Mt. Santubong, 17 km N Kuching, 200–400 m, 17-VIII-2003. Paratypes: 1 ex, same data as holotype (SMNK); 2 exx (ARC5228, very low DNA concentration, not sequenced), 11 mi SW Kuching, Semengoh Forest Reserve, leaf-mould berlesate RWT-68.197, 28-31-V-1968 (ANIC, SMNK).
Diagnostic description
Holotype. Male (Fig. 7a). Length 2.55 mm. Color of antennae light ferruginous; legs and elytra dark ferruginous; remainder black. Body in dorsal aspect subovate, with weak constriction between pronotum and elytron; in profile dorsally convex. Rostrum with median and pair of submedian ridges; intervening furrows with rows of punctures and sparse suberect scales; epistome with indistinct subangulate ridge, at middle with minute denticle. Pronotum with disk densely coarsely punctate, reticulate; each puncture containing small suberect scale. Elytra with striae distinct, with coarse punctures and rows of small suberect clavate scales; intervals weakly costate, subglabrous. Femora with weakly crenate anteroventral ridge. Profemur in basal third with weakly denticulate posteroventral ridge. Metafemur subapically with stridulatory patch. Dorsal edge of tibiae with subbasal, blunt angulation. Abdominal ventrites 1–2 forming deep common cavity, at middle weakly concave, glabrous, laterally and posteriorly with distinct rim; lateral rim of ventrite 2 in profile projecting dentiform; abdominal ventrite 5 medially concave, microreticulate, with sparse punctures, laterally with distinct ridges. Penis (Fig. 7b) with sides of body subparallel; with rhombiform orifical sclerite, medially with pincer-shaped sclerites; apex subangulate; transfer apparatus spiniform; apodemes 2.5 × as long as body; ductus ejaculatorius with distinct bulbus. Intraspecific variation. Length 2.38–2.55 mm. Female unknown.

Notes
Trigonopterus sarawakensis sp. nov. is coded as “Trigonopterus sp. 1244”. This species belongs to the Trigonopterus attenboroughi group. It is closely related to Trigonopterus attenboroughi Riedel, 2014 and Trigonopterus mulensis sp. nov., from which it can be distinguished by the subangulate apex of the penis and 8.2–9.2% p-distance of its cox1 sequence.
