- Antenna with microsetae on antennomeres V to XI ( Fig. 14 View FIGURES 14 – 19 ); antennomere IV as long as wide ( Fig. 14 View FIGURES 14 – 19 ), pronotum with setal punctuations forming a pair of longitudinal parallel lines in the median region and distributed in the lateral thirds (Fig. 5–7); sternite VII of male with porous structure (Figs. 30–32)...................................................... 4
