Diagnostic description

Holotype, male (Fig. 6a). Length 2.54 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 carinae; intervening furrows with rows of erect yellowish scales; epistome indistinct, sparsely setose. Pronotum with disk densely, coarsely punctate; interspaces between punctures subglabrous, subequal or less than punctures´ diameter; sublaterally some 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 blunt 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 at base of uncus with fine pointed brush of long setae. Abdominal ventrites 1–2 concave, sublaterally behind metacoxa with patch of erect white scales; ventrite 5 concave, subglabrous, microreticulate, in basal 1/2 with median carina, apex curved ventrad forming thin bilobed lamina. Penis (Fig. 6b) with body differentiated into weakly sinuate inner frame and narrow lateral membranous lobes; converging towards weakly anchor-shaped apex; apodemes 1.8 × as long as body of penis; transfer apparatus hook-shaped, ca. 0.6 × length of body; ductus ejaculatorius without distinct bulbus. Intraspecific variation. Length 2.38–2.54 mm. Female rostrum slender, dorsally subglabrous, with submedian and sublateral rows of minute punctures. Female abdominal ventrite 5 simple, flat, with sparse scales.

Material examined

Holotype (MZB): ARC3179 (EMBL # LN884969), SE-Sulawesi Prov., N Kolaka, Uluwolo village, 03°48.073'S 121°16.856'E, 182 m, sifted, 21-IV-2013. Paratype (SMNK): 1 ex, ARC3180 (PCR failed), same data as holotype.

Distribution

SE-Sulawesi Prov. (Kolaka). Elevation ca. 180 m.

Biology

In leaf litter of lowland forest.

Etymology

This epithet is based on the Latin adjective analis, e (pertaining to the anus) and refers to the peculiar morphology of ventrite 5.

Notes

Trigonopterus analis Riedel, sp. n. was coded as “Trigonopterus sp. 473”. This species is very closely related to Trigonopterus pseudanalis 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 more slender body shape with a less densely punctate pronotum.
