Diagnosis

Males can be distinguished from all congeneric species by their bipartite palpal retrolateral tibial apophysis (Fig. 13). Females are distinguished by their elongated wave-shaped epigynal Fap (Fig. 15).

Etymology

The speciFc name is a noun in apposition taken from the Kichwa language meaning rain.
