Diagnostic description
Holotype (MZB). Male (Fig. 18a). Length 2.75 mm. Color of antennae ferruginous; legs dark ferruginous; remainder black. Body subovate; in dorsal aspect with weak constriction between pronotum and elytron; in profile dorsally convex. Rostrum with median and pair of submedian ridges; epistome distinct, posteriorly with subangulate ridge bearing five denticles. Pronotum with very weak subapical constriction; disk densely punctate; median line impunctate; interspaces between punctures subglabrous, subequal to punctures’ diameter. Elytra with striae marked by rows of small punctures and fine hairlines; along basal margin with transverse row of denser punctures; stria 8 along humerus with seven coarse punctures; intervals subglabrous with interspersed punctures. Femora edentate, with distinct anteroventral ridge weakly crenate. Metafemur with dorsoposterior edge crenate; subapically with stridulatory patch. Posterior surface of metatibia with in apical half covered with long subrecumbent setae. Abdominal ventrites 1–2 concave, microreticulate, with sparse punctures; behind metacoxa with angular knob; ventrite 5 concave, subglabrous, sublaterally and subapically with sparse erect scales. Penis (Fig. 18b) with sides of body subparallel; apex symmetrical, with median triangular extension and sparse setae; apodemes 2.0× as long as body of penis; transfer apparatus Ʊ-shaped; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.48–3.36 mm. Female rostrum smooth and flat, epistome indistinct. Female metatibia subbasally dorsally somewhat widened, denticulate. Female abdominal ventrite 1 and 2 concave, subglabrous, laterally with few setae. Female abdominal ventrite 5 flat, medially glabrous, sublaterally and subapically punctate.

Distribution
C-Sulawesi Prov. (Mt Dako). Elevation 830–1250 m.
Biology
On foliage in montane forest.
Etymology
This species is named in honor of Saleh Poespo, grandfather of the first author, and for his pioneering animal husbandry science in Indonesia. An invariable genitive.
Notes
Trigonopterus puspoi sp. nov. was coded as “Trigonopterus sp. 1113” (Narakusumo et al. 2020[1]) and belongs to the T. palopensis-group. It is closely related to T. tolitoliensis sp. nov., from which it differs by its simple penis surface, the pubescence of the metatibia, and a 16.4–18.1% p-distance of its cox1 sequence.
