Diagnostic description

Holotype, male (Fig. 67a). Length 2.40 mm. Color of antennae ferruginous; remainder black. Body ovate, almost without constriction between pronotum and elytron; in profile evenly convex. Rostrum dorsally punctate; with dorsolateral furrows. Eyes with dorsal margin bordered by furrow, continuous with forehead, not carinate. Pronotum subglabrous, sparsely punctate with minute punctures, laterally above procoxa with sparse coarse punctures. Elytra subglabrous, striae hardly visible but marked by few deeper punctures along basal margin and near apex; humeral region subglabrous. Femora subglabrous, with minute punctures; with anteroventral ridge distinct, simple. Posterior surface of metafemur with two longitudinal furrows; with simple dorsoposterior edge; subapically without stridulatory patch. Mesotibia basally rounded; subapically with uncus and larger premucro. Metatibia subapically with fringe of curved, white setae; with uncus, without premucro. Abdominal ventrite 2 swollen, with posterior edge projecting, medially forming common cavity with ventrite 1; ventrite 5 dull, microreticulate, punctate, with shallow subapical depression. Penis (Fig. 67b). Apex symmetrical, with median triangular extension; apodemes 2.7 × as long as body of penis; transfer apparatus dentiform, apically bordered by pair of L-shaped sclerites; ductus ejaculatorius with indistinct bulbus. Intraspecific variation. Length 2.24–2.63 mm. Female mesotibia subapically with uncus and minute premucro. Female metatibia subapically simple, without fringe of long setae.

Distribution

S-Sulawesi Prov. (Pc. Palopo); C-Sulawesi Prov. (Pendolo, Luwuk). Elevation 760–1050 m.

Biology

On foliage in montane forests.

Etymology

This epithet is based on the Greek prefix pseudo- (false) and the name of Trigonopterus allotopus Riedel, a sibling species. A noun in apposition.

Notes

Trigonopterus pseudallotopus Riedel, sp. n. was coded as “Trigonopterus sp. 945”. This species is closely related to Trigonopterus allotopus Riedel, from which it differs by ca. 5.8–6.4% p-distance of cox1 and morphologically by the weakly impressed striae 7–9 of the elytral humeri.
