Presence of two pairs of hook shaped sclerotized projections in the aedeagal complex; one directed dorsally and the other directed outward. Aedeagus subtriangular ending in the midline of projections in the aedeagal complex. Ejaculatory apodeme long, twice the length of projections in the aedeagal complex ( Figs. 1 F, 1 EView FIGURES 1 A – G). Epandrium wider than long, subrectangular ( Fig. 1 DView FIGURES 1 A – G).
