Stephanopis renipalpis Mello-Leitão, 1929: 60   , figs 143–144.

Note

Mello-Leitão (1929) also designated a “cotype” (MNHN 17335) of S. renipalpis   from Pernambuco; however, the specimen was not found.

Diagnosis

The male of K. renipalpis   is similar to that of K. quinquetuberculata   due to their well-developed MS, light clypeus and white macula on dorsum ( Fig. 15A–B View Fig ). However, it can be distinguished from this and other congeneric species by the medially positioned spermatic duct ( Figs 15C, E View Fig , 19D) and extreme curvature of the RTA, which is thinner than in the other species and smooth at the tip ( Figs 15D, F View Fig , 19D).
