Diagnostic description
Holotype. Male (Fig. 6a). Length 2.28 mm. Color of antennae and legs ferruginous; remainder black. Body subovate, elongate; in dorsal aspect and in profile with weak constriction between pronotum and elytron. Rostrum dorsally with median costa and pair of submedian ridges; intervening furrows with sparse rows of subrecumbent setae; epistome indistinct. Pronotum with disk densely punctate; interspaces between punctures subglabrous. Elytra with striae marked by fine hairlines and rows of small punctures; basal margin bordered row of slightly larger punctures; sutural interval subglabrous, with few interspersed punctures. Profemur with anteroventral ridge weakly crenate. Meso- and metafemur with anteroventral ridge denticulate; anterior surface of femora coarsely punctate, each puncture with narrow recumbent scale. Metafemur with dorsoposterior edge indistinct; subapically with stridulatory patch. Metatibia ventrally with sparse row of long, stiff setae. Meso- and metaventrite with plumose scales. Abdominal ventrites 1–2 concave, microreticulate, with sparse punctures and plumose scales; ventrite 5 flat, densely punctate, microreticulate. Penis (Fig. 6b) with sides of body converging, apex spatulate, truncate, without setae; ostium elongate; apodemes 2.1× as long as body of penis; transfer apparatus small, hook-shaped, directed basad in repose, without supporting sclerites; ductus ejaculatorius with indistinct bulbus.

Distribution
C-Sulawesi Prov. (Mt Dako). Elevation 970–1200 m.
Biology
On foliage in montane forest.
Etymology
This epithet is the Indonesian word for “leaf” and a noun in apposition. It refers to the species´ lifestyle on foliage.
Notes
Trigonopterus daun sp. nov. was coded as “Trigonopterus sp. 1116” (Narakusumo et al. 2020[1]). This species belongs to the T. tatorensis-group. It is closely related to T. acutus sp. nov., from which it can be distinguished by the erect metatibial setae, and the truncated apex of the penis. The cox1 p-distance is 10.0–10.5%.
