Diagnosis.
Males of
Epicratinus amazonicus
can be recognized by the RTA shape with a triangular distal part with a tip directed towards the center of the cymbium. The females are characterized by a central depression transversally oval in the epigynum and the copulation ducts with three turns within the spermathecae (
Figs 7
A–E).
