Male genitalia: Pygophore squared shape. In dorsal view, dorsal rim constricted anterolaterally ( Fig. 9 View FIGURES 6–20 ); median projection of dorsal rim short, sinuosity deep; superior process of dorsal rim flap-like ( Fig. 10 View FIGURES 6–20 ). Ventral rim strongly bilobed, concave mesially in ventral view ( Fig. 11 View FIGURES 6–20 ). In posterior view, ventral rim smooth mesially. Paramere: margin connecting basal and apical process slightly concave; apical process rounded apically; middle process developed, produced as a small tooth ( Fig. 23 View FIGURES 21–26 ).

Female genitalia: Posterior margin of gonocoxites VIII slightly concave; posterolateral margin of gonocoxites VIII projected posteriorly, reaching at most middle of gonocoxites IX. Gonocoxites IX 2.5 times wider than long, tapering laterally; anterior margin of gonocoxites IX convex ( Fig. 48 View FIGURES 45–59 ). Laterotergites IX surpassing dorsal band that unites laterotergites VIII in posteroventral view. Posterior region of ductus receptaculi proximalis dilated in a cup-like sclerotized structure. Ductus receptaculi distalis slightly dilated adjacent to anterior annular flange. Pars intermedialis dilated medially ( Fig. 61 View FIGURES 60–64 ).
