Diagnosis
Males are easily distinguished from all congeneric species by their basally wide and twisted embolus and their large ventral tegular projection ( Fig. 49 View Figs 49 – 53 ). Females are distinguished by the shallow, pocket-like lateral epigynal grooves ( Fig. 52 View Figs 49 – 53 ).
Etymology
The speciFc name is a noun in apposition is taken from the Kichwa language meaning ‘twisted’, reFecting the twisted embolus of the male palp.
