Diagnostic description.

Holotype, male (Fig. 60a). Length 1.72 mm. Color of head and legs ferruginous, remainder black. Body in dorsal aspect with marked constriction between pronotum and elytron; with indistinct constriction in profile. Rostrum dorsally coarsely punctate-scabrous; median ridge and pair of submedian ridges indistinct; epistome with transverse, subangulate ridge indistinct. Pronotum with subapical constriction; disk coarsely punctate, sparsely setose; with pair of curved sublateral impressions; medially swollen. Elytra relatively slender; with striae deeply impressed, each with row of suberect bristles; intervals costate, subglabrous; apex narrow, rounded. Femora each with small tooth. Metafemur subapically with stridulatory patch. Abdominal ventrite 5 coarsely punctate, with median impression bordered by pair of longitudinal costae. Penis (Fig. 60b) with sides subparallel, in apical third markedly converging to narrow apex, medially with sparse setae; transfer apparatus flagelliform, 4.1 × as long as body; apodemes 3.7 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.70-2.14 mm. Penis with flagelliform transfer apparatus 4.1-4.6 × as long as body; apodemes 3.7-4.0 × as long as body. No females available.

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


Trigonopterus pseudoflorensis  Riedel, sp. n. was coded as " Trigonopterus  sp. 352" by Tänzler et al. (2014). Morphologically it is very similar to Trigonopterus florensis  Riedel, sp. n. and Trigonopterus paraflorensis  Riedel, sp. n. but its cox1 sequences differ 6.69%, respectively 7.14% smallest interspecific p-distance.
