Diagnostic description.

Holotype, male (Fig. 54a). Length 2.06 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 with median ridge and pair of submedian ridges, anteriorly coarsely punctate-scabrous; epistome with transverse, subangulate ridge. Pronotum with subapical constriction; disk coarsely punctate-reticulate, sparsely setose; with pair of curved sublateral impressions; medially swollen. Elytra relatively slender; with striae deeply impressed, each with row of short 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 weak longitudinal costae. Penis (Fig. 54b) with sides subparallel, in apical third markedly converging to narrow subglabrous apex; transfer apparatus flagelliform, 6.6 × as long as body; apodemes 4.0 × as long as body; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.70-2.20 mm. Penis with flagelliform transfer apparatus 6.0-6.9 × as long as body; apodemes 3.4-4.1 × as long as body. No females available.

Material examined.

Holotype (MZB): ARC3622 (EMBL # LM656052), East Nusa Tenggara Prov., Flores, Ruteng, Mt. Ranaka, sample 7, S08°37.781', E120°31.184', 1730 m, 10-III-2011. Paratypes (MZB, SMNK): Flores: 4 exx, ARC2205 (EMBL # LM655661), ARC2206 (EMBL # LM655662), ARC3623 (EMBL # LM656053), ARC3624 (EMBL # LM656054), same data as holotype.

Distribution.

East Nusa Tenggara Prov., Flores (Mt. Ranaka). Elevation: 1730 m.

Etymology.

This epithet is based on a combination of the Greek prefix para- (next to; near by) and the specific epithet of Trigonopterus florensis Riedel, sp. n., a sibling species.

Notes.

Trigonopterus paraflorensis Riedel, sp. n. was coded as " Trigonopterus sp. 441". Morphologically it is very similar to Trigonopterus florensis Riedel, sp. n. and Trigonopterus pseudoflorensis Riedel, sp. n. but its cox1 sequences differ 7.75%, respectively 7.14% smallest interspecific p-distance.
