Genitalia: paramere wide in dorsal view, apex weakly serrated in ventral view, narrow, arched, smaller than to basiparamere; cuspis very short in ventral view; digitus wide; aedeagal ventral ramus smaller than dorsal body, laminar, base ill-defined, apex rounded, basal projection; aedeagal dorsal body with two pair of apical lobes, outer pair with apex weakly rounded, inner pair membranous; basal process with two projections, apex straight, wide; apodeme extending beyond genital ring.
