Name
Trigonopterus inflatus Riedel sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Diagnostic description
Holotype, male (Fig. 38a). Length 2.90 mm. Color black, elytra with greenish-bronze lustre; antenna light ferruginous, legs dark ferruginous. Body subovate; in dorsal aspect and in profile almost without constriction between pronotum and elytron. Rostrum with distinct median and pair of submedian carinae, in apical third scabrous; epistome simple. Pronotum relatively small, with weak subapical constriction; disk densely punctate, longitudinally rugose; each puncture with seta, a few with scale. Elytra with striae deeply impressed; with sparse, yellowish scales; intervals subglabrous. Meso- and metafemur edentate. Metafemur with dorsoposterior edge serrate, subapically without stridulatory patch. Metatibia apically with blunt premucro. Onychium ca. 1.1× longer than tarsomere 3. Aedeagus (Fig. 38b) with apex asymmetrical, right side forming biramose extension; basal orifice ventrally with rim; transfer apparatus spiniform, curved, directed basad; ductus ejaculatorius without bulbus. Intraspecific variation. Length 2.45–2.90 mm. Female rostrum dorsally subglabrous, with dense small punctures, in basal third with longitudinal ridges. Female metatibia apically without premucro.
Material examined
Holotype (MZB): ARC0858 (EMBL # HE615540), WEST NEW GUINEA, Biak Isl., Korim, Nernu, S00°55.784', E136°01.530', 165 m, 15-XII-2007, sifted. Paratypes (ARC, SMNK, ZSM): WEST NEW GUINEA, Biak Isl.: 28 exx, ARC0859 (EMBL # HE615541), same data as holotype; 1 ex, ARC0883 (EMBL # HE615565), Korim, Nernu, S00°55.888', E136°01.671', 180 m, 15-XII-2007, sifted; 3 exx (1 marked ARC0093), Korim, Nernu, 150 m, 20-I-2005, sifted.
Distribution
Biak Isl.. Elevation: 150–180 m.
Biology
Sifted from leaf litter in lowland forest.
Etymology
This epithet is based on the Latin participle inflatus (swollen) and refers to the shape of the elytra that appear somewhat disproportionate in relation to the pronotum.
Notes
Trigonopterus inflatus Riedel, sp. n. was coded as “Trigonopterus sp. 63” by Tänzler et al. (2012)[1].
