Name

Diagnostic description
Holotype, male (Fig. 26a). Length 1.41 mm. Color black; antenna light ferruginous, club dark; legs and head dark ferruginous. Body subglobose; with distinct constriction between pronotum and elytron; in profile almost evenly rounded, with weak constriction between pronotum and elytron. Rostrum basally with indistinct, median ridge and pair of submedian ridges, sparsely setose; apical 1/3 subglabrous; epistome simple. Eyes small. Pronotum with weak subapical constriction; disk densely, coarsely punctate; each puncture with short, yellowish scale. Elytra with striae deeply incised; with suberect, yellowish scales; intervals subglabrous, markedly costate. Femora subapically ventrally constricted. Metafemur subapically with stridulatory patch. Protibia with long, hook-shaped uncus. Aedeagus (Fig. 26b) with apex rounded; transfer apparatus symmetrical, spiniform; ductus ejaculatorius with indistinct bulbus. Intraspecific variation. Length 1.28–1.54 mm. Female rostrum basally without ridges; apical half subglabrous. Suberect scales may be partly abraded.
Material examined
Holotype (MZB): ARC0781 (EMBL # HE615464), WEST NEW GUINEA, Manokwari, Arfak Mts, S01°04.087', E133°54.268', 1520 m, 08-XII-2007, sifted. Paratypes (SMNK, ZSM): 21 exx, ARC0782 (EMBL # HE615465), ARC0783 (EMBL # HE615466), same data as holotype; Mokwam, Siyoubrig, S01°06.107', E133°54.888', 1530 m, 10–XII-2007.
Distribution
Manokwari Reg. (Arfak Mts). Elevation: 1520 m.
Biology
Sifted from leaf litter in montane forest dominated by Nothofagus.
Etymology
This epithet is based on the Latin noun echinus (hedgehog) in apposition and refers to the species´ general habitus and its suberect scales resembling spines.
