- Elytra with all striae completely developed. Interval 3 with discal pore puncture. Last abdominal sternite marginally with two setae at each side in male.....................................2

2 Pronotum from widest point weakly convex and strongly sinuate toward the longer, weakly obtuse-angled but sharp posterior angles, denticle absent. Antennomere 2 and 7-11 with a blackish stripe at middle. Humeri more strongly developed. Eyes moderately convex. Elytra longer (EL/EW 1,51). Median lobe with a long, narrow, parallel-sided apical lamella ( Figs 2, 3 ). Body size larger, 4.6 mm (up to now only one male known)..............................................................

- Pronotum from widest point almost rectilinearly narrowed toward the short, weakly obtuse-angled but sharp posterior angles, a small denticle present. Antennomere 2 and 7-11 of the same colour as antennomere 1. Humeri less strongly developed. Eyes fairly flat. Elytra shorter (EL/EW 1.48). Median lobe with apical lamella evenly narrowed ( Figs 6, 7 ). Body size smaller, 3.9 mm (up to now only one male known). .......................... .........................................................................
