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).
