Holotype (SMNS): ARC7272 (GenBank # OP078712), E-Malaysia, Sarawak, Mulu NP, 100 km SEE Miri, 200 m, 19-24-VIII-2003, sifted. Paratype (SMNK): 1 ex, same data as holotype.
Diagnostic description
Holotype, male (Fig. 6a). Length 2.75 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.

Elytra with striae distinct, with small punctures and rows of small suberect scales; intervals costate, subglabrous, coriaceous, sutural interval with row of minute punctures. Femora with simple anteroventral ridge. Metafemur dorsally coarsely punctate; subapically with stridulatory patch. Dorsal edge of tibiae subbasally dentate, in pro- and mesotibia denticle acute, in metatibia blunt; metatibia posteriorly with dense white subclavate scales. 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 at middle with round subglabrous concavity, laterally swollen, punctate. Penis (Fig. 6b) with sides of body subparallel; with large p-shaped sclerite in apical half; apex bisinuate, with median incision; transfer apparatus small, dentiform; apodemes 1.8 X as long as body; ductus ejaculatorius without distinct bulbus.

Notes
Trigonopterus mulensis sp. nov. is coded as “Trigonopterus sp. 1248”. This species belongs to the Trigonopterus attenboroughi group. It is closely related to Trigonopterus attenboroughi Riedel, 2014 and Trigonopterus sarawakensis sp. nov., from which it can be distinguished by its dense white scales of the metatibia and 9.2–10.3% p-distance of its cox1 sequence.
