Vertex straight, with rounded corners. Metasomal tergite II with pair of inclined elliptical and shallow lateral depressions, with two long lateral setae, distant each 1.64 X their diameters, with an anterior tuft of very short hairs ( Fig. 115 ). Genitalia ( Figs. 116–117 ): paramere wide, apical margin strongly concave, corners produced ( Fig. 118 ); volsella with cuspis not arched, digitus long, dorsal margin smooth, cuspis and digitus nearly as high as the apex of paramere, basivolsella with very long inner expansion, its outer margin dilated serrate, slightly shorter than the cuspis ( Fig. 119 ); aedeagus with ventral ramus deeply excavated medially, apical third with surface subvertical, with some teeth below, dorsal body with two pairs of apical lobes, inner pair stout, membranous and hairy, outer pair laminar, surface vertical, wide in lateral view, with rounded apex, and dorsal margin strongly serrate apically, deeply excavated medially and with spine basally ( Fig. 120 ).
