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.
