Diagnosis

Males are easily distinguished from all species in the genus by their short and strongly curved median apophysis ( Fig. 55 ). Females are diagnosed by the lateral epigynal grooves producing very deep cavities ( Fig. 58 ).

Etymology

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