Anterior gonopod sternite basally wide, apically elevated into a well-rounded tip ( Fig. 64AView Figure 64). Mesal process of coxite wide and only slightly protruding ( Fig. 64AView Figure 64). Apical process of telopodite slender and well-rounded. Retrorse margin wide, not projecting ( Fig. 64CView Figure 64).

Posterior gonopods telopodite bent 60° ( Fig. 64DView Figure 64). Projection absent from lateral margin (w, Fig. 64BView Figure 64). Apical process (x) wide, tapering ( Fig. 64BView Figure 64). Membranous lobe (y) small ( Fig. 64BView Figure 64). Projection of sperm canal (z) basally wide, apically tapering, curved towards coxite ( Fig. 64DView Figure 64).
