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 View Figs 17 – 21 ), remotely positioned in the latter species ( Fig. 23 View Figs 22 – 26 ). 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’.
