Diagnostic description

Holotype, male (Fig. 60a). Length 1.54 mm. Antenna, legs, and head ferruginous; pronotum, elytra, and tarsi black. Body subovate; in dorsal aspect and in profile with distinct constriction between pronotum and elytron. Rostrum punctate; epistome simple. Eyes small, anterior margin angularly projecting. Pronotum with weak subapical constriction; disk densely, coarsely punctate; each puncture with short, yellowish scale. Elytra with striae deeply impressed; each puncture with suberect, yellowish scale; intervals subglabrous, costate, partly transversely confluent. Meso- and metafemur ventrally dentate. Metafemur subapically without stridulatory patch. Onychium ca. 1.6× longer than tarsomere 3. Aedeagus (Fig. 60b) with apex asymmetrical, right side forming long curved extension; basal orifice ventrally with rim; transfer apparatus dentiform; ductus ejaculatorius without bulbus. Intraspecific variation. Length 1.46–1.54 mm. Female rostrum slightly longer, dorsally subglabrous, sparsely punctate, in basal third coarsely punctate. Female elytral apex markedly extended ventrad, beak-shaped. Abdominal ventrite 3 of females with flattened process projecting over ventrite 4, medially with bifid extension reaching base of ventrite 5, sublaterally with pair of shorter spines. Female abdominal ventrites 4–5 weakly sclerotized.

Material examined

Holotype (MZB): ARC0832 (EMBL # HE983631), WEST NEW GUINEA, Manokwari, Arfak Mts, Mokwam, Siyoubrig, S01°07.066', E133°54.710', 1870 m, 11-XII-2007, sifted. Paratypes (SMNK, ZSM): 23 exx, ARC0833 (EMBL # HE615515), ARC0834 (EMBL # HE615516), same data as holotype.

Distribution

Manokwari Reg. (Arfak Mts). Elevation: 1870 m.

Biology

Sifted from leaf litter in montane forest.

Etymology

This epithet is based on the Latin adjective parvulus (little) and refers to the species´ small body size.

Notes

Trigonopterus parvulus Riedel, sp. n. was coded as “Trigonopterus sp. 233” by Tänzler et al. (2012)[1].
