Diagnosis:
This species is characterized by the presence of a short, narrow process on the male palpal tibia, by the apically pointed distal suprategular apophysis in the male, as well as by the rounded receptacula in the female.
Etymology:
The specific epithet is a Latin adjective referring to the shape of the apical part of the distal suprategular apophysis.
