Figs 17–21

Diagnosis

Males can be distinguished from all species by their elongated, serrated palpal retrolateral tibial apophysis with small dorsal spur, from K. guayasamini sp. nov. by the closely positioned dorsal spur ( Fig. 18 ), remotely positioned in the latter species ( Fig. 23 ). Females are distinguished by their knob-like epigynal Fap (Fig. 20).

Etymology

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