Diagnostic description

Holotype, male (Fig. 68a). Length 2.95 mm. Color of antennae and legs ferruginous; remainder black with slight bronze luster. Body subovate; in dorsal aspect with weak constriction between pronotum and elytron; in profile dorsally convex. Rostrum dorsally with median and pair of submedian ridges; intervening furrows with rows of erect yellowish scales; epistome indistinct, subglabrous, sparsely setose. Pronotum with disk densely, coarsely punctate; punctures subovate, with oblique anteriomesad orientation; interspaces between punctures subglabrous, reticulate; in anterior 1/2 punctures with clavate, yellowish scale; median line impunctate. Elytra irregularly punctate with small punctures; interspaces subglabrous; basal margin bordered by deeper punctures and almond-shaped yellowish scales; near apex striae more distinctly impressed, with sparse rows of yellowish scales; apex subtruncate. Femora with anteroventral ridge ending with small tooth; anterior surface coarsely punctate, each puncture with narrow yellowish scale. Metafemur with dorsoposterior ridge denticulate, subapically with stridulatory patch. Meso- and metatibia with dorsal edge irregularly serrate. Metatibia ventrally with fine ridge; subapically near uncus with fine row of long setae. Abdominal ventrites 1–2 weakly concave, with scattered erect white scales, especially behind metacoxa; ventrite 5 concave, subglabrous, microreticulate, at basal margin with median denticle and pair of sublateral denticles, apex curved ventrad forming truncate lamina. Penis (Fig. 68b) with body at middle with narrow lateral membranous lobes; weakly converging; apex subtruncate, sparsely setose; apodemes 1.7 × as long as body of penis; transfer apparatus hook-shaped, ca. 0.4 × length of body, basally continued as fork-shaped sclerite; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.18–2.95 mm. Female rostrum slender, dorsally subglabrous, with submedian and sublateral rows of punctures. Female abdominal ventrite 5 weakly concave, punctate, with sparse scales.

Material examined

Holotype (MZB): ARC3213 (GenBank # MK260628), S-Sulawesi, Mangkutana, 02°20.306'S 120°46.792'E, 909 m, sifted, 14-V-2013. Paratypes (MZB, SMNK): S-Sulawesi: 6 exx, ARC3214 (GenBank # MK260629), ARC3215 (GenBank # MK260630), ARC3216 (PCR failed), same data as holotype; 5 exx, Mangkutana, 02°20.203'S 120°46.878'E, 903 m, sifted, 14-V-2013; C-Sulawesi: 1 ex, ARC3140 (PCR failed), Pendolo, Boe, 02°05.405'S 120°38.551'E, 857 m, sifted, 15-V-2013.

Distribution

S-Sulawesi Prov. (Mangkutana), C-Sulawesi Prov. (Pendolo). Elevation 860–910 m.

Biology

In leaf litter of lowland forest.

Etymology

This epithet is a Latinized adjective based on the Greek prefix pseudo- (false) and the name of Trigonopterus analis Riedel, sp. n., a sibling species.

Notes

Trigonopterus pseudanalis Riedel, sp. n. was coded as “Trigonopterus sp. 944”. This species is very closely related to Trigonopterus analis Riedel, sp. n., from which it differs by ca. 11.7–12.7% p-distance of cox1, by the apex of the penis, and by a stouter body shape with a more densely punctate pronotum.
