Diagnosis Males of Idiops camelus ( Fig. 11A–I , 12 ) differ from other Neotropical species by having the apical half of the embolus tapering ( Fig. 11D–F ), with the presence of a distal embolar tooth (also present in I. clarus and I. germaini ) close to the opening of the sperm duct ( Fig. 12E–F ). Differs from I. clarus and I. germaini by having the apical portion of the embolus more expanded ( Fig. 12E–F ). Females ( Fig. 11J–L ) have spermathecae with spherical receptacles slightly wider than the ducts, with a subtle constriction between duct and receptacle ( Fig. 11L ).
