Key to the Peruvian species of Epirhyssa 

The following key works best for females. For this reason, the identification of male specimens should always be confirmed by comparing them with female specimens and descriptions. The females of the Peruvian species E. eucnemis Porter  and E. melampyge Porter  are unknown and we have not included them in the key. However, both of these species may be identified using the diagnoses provided below.
