Diagnosis

Males can be distinguished from all congeneric species by the apically serrated plate-like palpal retrolateral tibial apophysis ( Fig. 8 ); from K. simplicipalpis (Simon, 1897) , by the white nub at the end of the abdomen, absent in the latter species (Brescovit 1997: Fg. 99). Females are distinguished by the small V-shaped epigynal Fap (Fig. 10), from K. simplicipalpis (Simon, 1897) by the elongated copulatory ducts, short and coiled in the latter species (Brescovit 1997: Fg. 103).

Etymology

The speciFc name is a noun in apposition taken from the Kichwa language meaning ‘fog’.
