Diagnostic description
Holotype, male (Fig. 28a). Length 3.66 mm. Color black; tarsi and antenna ferruginous. Body ovate; with weak constriction between pronotum and elytron; in profile evenly convex. Rostrum dorsally with distinct median carina and sparse rows of upcurved scales; submedian ridges indistinct, irregular. Pronotum densely punctate except along impunctate midline. Elytra punctate with minute punctures, especially on intervals; strial punctures slightly larger; striae impressed as fine lines; lateral stria behind humeri simple, not deepened. Femora edentate. Metafemur with denticulate dorsoposterior edge; subapically with fine stridulatory patch. Metatibia apically with uncus, without premucro. Abdominal ventrite 5 flat, densely setose with suberect setae. Aedeagus (Fig. 28b) slightly asymmetrical; with distinct, asymmetrical transfer-apparatus; ductus ejaculatorius with bulbus. Intraspecific variation. Length 3.38–3.72 mm. Female rostrum dorsally in basal half with median and pair of submedian ridges, apical half punctate. Female abdominal ventrite 5 flat, sparsely setose with recumbent setae.
Material examined
Holotype (MZB): ARC426 (EMBL # FN429137), WEST NEW GUINEA, Jayapura Reg., Cyclops Mts, Sentani, S02°31.2', E140°30.5', 1420–1520 m, 30-XI-2007, beaten.

Distribution
Jayapura Reg. (Cyclops Mts). Elevation: 1400–1420 m.
Biology
Collected by beating foliage in montane forests.
Etymology
This epithet is the latinized form of the Greek noun eremites (hermit) and refers to the species´ restricted occurrence in the montane forests of the Cyclops Mountains.
