Diagnosis.

Beetle middle-sized (TL-H 4.8-5.0 mm, TL 5.1-5.3 mm, MW 2.6 mm), piceous, dull (Fig. 24); pronotum with distinct lateral bead; male antennomeres simple; male protarsomere 4 with large, thick, strongly curved anterolateral hook; median lobe without submedian constriction but with lateral folds in ventral view and apex pointed and curved downwards in lateral view; paramere without notch on dorsal side, with relatively dense, long, thin setae.

Additions and corrections to the description.

For the complete description and illustrations see Shaverdo et al. (2005).

Structures: Pronotum with distinct lateral bead. Base of prosternum and neck of prosternal process with sharp ridge and well developed anterolateral extensions. Blade of prosternal process lanceolate, rather narrow, with strong longitudinal convexity; neck and blade of prosternal process evenly jointed, except for weak concavity in front of jointion of protrochanters.

Male: Protarsomere 4 with large, thick, strongly curved anterolateral hook. Median lobe without submedian constriction but with lateral folds in ventral view and with apex pointed and curved downwards in lateral view. Paramere without notch on dorsal side, with relatively dense, long, thin setae. See Figs 10, 15a, b in Shaverdo et al. (2005).

Female: Without evident differences in external morphology from male, except for abdominal sternite 7 without striae.

Distribution.

Papua New Guinea. The species is known only from Crater Mountain, Simbu and Eastern Highlands Provinces (Fig. 50).
