Diagnosis. Males of Patrera auricoma can be distinguished from the remaining species by its long and apically bifid retrolateral tibial apophysis with both branches of equal length ( Fig. 3C ̅E). Females are diagnosed by coiled and exceptionally long copulatory ducts, and oval and anteromedially positioned spermathecae ( Fig. 3F ̅G).
