Head: Antennal capitulum long ( Fig. 78 ), basal capitular antennomere longer than combined length of funicular antennomeres; antennal carina very prominent; EW/FW 20/20. Thorax: Pronotum elongate, anterior margin not projected at middle, side margin of disc with shallow tubercle; PW/PL 60/70; elytral not strongly explanate at sides, carina faintly visible; EL/EW 270/70.
