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.
