1’. Humeral angles of pronotum strongly developed, spine-like; posterior margins of gonocoxites 8 obliquely truncate; sutural angles of gonocoxites 8 truncate.......................................................................... 3
2(1). Mandibular plates longer than clypeus not contiguous (Fig. 2); antennal segment I barely reaches apex of mandibular plates; superior process of dorsal rim of pygophore oblique at dorsal rim, projecting towards base of parameres for 1/3 of the distance from dorsal rim to base of parameres; ventral rim of pygophore indented medially, margin of indention parallel............................................................................
