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.
Material examined
Holotype (MZB): ARC2209 (EMBL # LM655665), East Nusa Tenggara Prov., Flores, Ruteng, Mt. Ranaka, sample 6, S08°38.243', E120°31.569', 1995 m, 09-III-2011. Paratypes (SMNK, ZSM): Flores: 3 exx, ARC3613 (EMBL # LM656043), ARC3614 (EMBL # LM656044), ARC3615 (EMBL # LM656045), Ruteng, Mt. Ranaka, sample 5, S08°38.277', E120°31.616', 2010 m, 09-III-2011.
Distribution
East Nusa Tenggara Prov., Flores (Mt. Ranaka). Elevation: 1995–2010 m.
Etymology
This epithet is based on the Greek prefix pseudo (false) and the name of Trigonopterus florensis Riedel, sp. n., a sibling species.
Notes
Trigonopterus pseudoflorensis Riedel, sp. n. was coded as “Trigonopterus sp. 352” by Tänzler et al. (2014)[1]. 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.
