Figs 60–64

Diagnosis

Males are easily distinguished from all species in the genus by their strongly curved ventral projection of subtegulum and embolus ( Fig. 60 ). Females are distinguished by their blunt knob-like projection and curved lateral epigynal grooves ( Fig. 63 ).

Etymology

The speciFc name is a noun in apposition taken from the Kichwa language meaning ‘elongated’ in reference to the elongated male palpal tibia.
