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 each with sparse row of recumbent piliform scales; epistome with one median denticle and two less distinct pairs of submedian / sublateral denticles. Pronotum with disk punctate with small punctures; interspaces subglabrous. Elytra punctate with small punctures; striae marked by fine hairlines; irregular intervals each with additional sparse row of punctures; interspaces between punctures subglabrous; stria 8 and 9 along humerus with somewhat larger punctures. Femora edentate; anterior surface punctate with small punctures, each with recumbent piliform scale. Metafemur subapically with stridulatory patch. Protibia widened to apex.

Penis (Fig. 24b) with sides of body subparallel; apex with median subangulate extension, sparsely setose; apodemes 2.5 × as long as body; transfer apparatus complex, with anchor-shaped basal sclerite; ductus ejaculatorius with indistinct bulbus.

Etymology

This epithet is a combination of the Latin adjective fuscus, -a, -um (dark, tawny) and the noun pes (foot, leg). A noun in apposition.

Notes

Trigonopterus fuscipes Riedel, sp. n. was coded as “Trigonopterus sp. 526”. This species is very closely related to Trigonopterus asterix Riedel, sp. n., from which it differs by ca. 12% p-distance of cox1 and by the structure of the male genitalia.
