  • Trigonopterus allotopus Riedel: Riedel et al. 2014[1]: 12–13.

Diagnostic description

Fig. 3a. Length 2.40–2.63 mm. Color of antennae ferruginous, legs dark ferruginous or black; remainder black. Body ovate, almost without constriction between pronotum and elytron; in profile dorsally convex. Rostrum dorsally punctate, weakly rugose; dorsolateral furrows with rows of piliform scales. 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 with few deeper punctures along basal margin and near apex; striae 7–9 at humerus marked by coarse punctures. 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; males subapically with uncus and larger premucro, females with minute premucro. Male metatibia subapically with fringe of curved, white setae, missing in female; with uncus, without premucro. Abdominal ventrite 2 swollen, with posterior edge projecting, in males medially forming common cavity with ventrite 1; ventrite 5 dull, microreticulate, punctate, with shallow subapical depression. Penis (Fig. 3b). Apex symmetrical, with median triangular extension; apodemes 2.8 × as long as body of penis; transfer apparatus dentiform, apically bordered by pair of L-shaped sclerites; ductus ejaculatorius with indistinct bulbus.

Material examined

Holotype (MZB): ARC1513 (EMBL # LM655611), West Nusa Tenggara Prov., Sumbawa, Batu Dulang, Mt Batu Pasak, sample 2, 08°37.028'S 117°15.783'E, 1305 m, 12-IV-2010. Other material examined (SMNK): SE-Sulawesi Prov.: 4 exx, ARC3163 (GenBank # MK260197), ARC3164 (GenBank # MK260199), ARC3165 (GenBank # MK260198), Kolaka, km 45 on Kendari-road, Talodo village, 04°00.686'S 121°50.198'E to 04°00.673'S 121°49.869'E, 450–565 m, 20-IV-2013.

Distribution

West Nusa Tenggara Prov. (Sumbawa); SE-Sulawesi Prov. (Kolaka). Elevation 565–1305 m.

Notes

This species originally described from Sumbawa Island was coded as “Trigonopterus sp. 331” by Tänzler et al. (2014)[2]. It is closely related to T.pseudallotopus Riedel, sp. n., from which it differs by ca. 5.8–6.4% p-distance of cox1 and morphologically by the deeply impressed striae 7–9 of the elytral humeri.
