Male antennae longer than those of female ( Fig. 4E, F View Figure 4 ). Antennomeres II longer than wide, III subquadrate and smallest, IV and V longer than wide, VI—VIII as long as wide, IX and X transverse ( Fig. 4E, F View Figure 4 ). Elytra. Male elytra longer than wide, female elytra shorter than those of male ( Fig. 1C, F View Figure 1 ). Abdomen. Male abdominal segment VI approximately three times as long as V, female with segment VI 1.5 times longer than V ( Fig. 1C, F View Figure 1 ). Aedeagus.
