Diagnosis. This species is characterized by the following features: eyes 0.4 x longer than interocular distance in dorsal view ( Fig. 21A ); antennae extending beyond pronotum posterior lateral apices by antennomere VI, surpassing elytral half by antennomere XI ( Fig. 21B ); antennomeres III longer than II; IV 2.6 x longer than III, 1.5x longer than II–III combined ( Fig. 21C ); apical maxillary palpomere 2.7 x longer than wide ( Fig. 21D ), longer than maximum length of eye; pronotum straightly narrowed and distinctly constricted anterior to hind angles; posterior edge of pronotum without sublateral incisions; hind angles of pronotum acute, strongly protruding posterolaterad; hypomeron with distinct mesial projection ( Fig. 21E ); anterior angle of hypomeron biangular, with mesial and outer angles rounded; hind angle of hypomeron narrowly triangular; scutellar shield 1.1 x longer than wide ( Fig. 21F ); mesosternal process between mesocoxae lower than mesocoxae, not visible in lateral view ( Fig. 21G ); posterior edge of mesosternal process 0.1 x wider than total width of mesosternum; elytron 5.0 x longer than wide, 4.3 x longer than pronotum length ( Fig. 21B ); abdominal ventrite V trapezoidal, round-sided, slightly concave apically ( Fig. 21H ); phallobase 0.9 x longer than wide; preapical expansions of parameres claw-like shaped ( Fig. 21I ); apex of parameres beyond preapical expansions blade-like shaped, 1.25 x width of parameres at expansions in ventral side.
