052387912127FFBCFF4DFD58FCE54438.taxon	diagnosis	Diagnosis. Epirhyssa leonoreae is very similar to Epirhyssa oranensis, but the former differs in having different colour patterns on the propodeum and metasoma. In the key to Peruvian species (Gómez et al., 2015), E. leonorae goes to couplet 16, but differs from the included species in having the occipital carina joining the hypostomal carina and having tergite I about 1.5 × as long as wide. The darkened shallow groove extending from the subalar prominence to the mesopleural fovea is unusual among Epirhyssa species.	en	Zuñiga, Ronald, Hanson, Paul (2024): Two new species of Epirhyssa (Hymenoptera: Ichneumonidae: Rhyssinae) from Costa Rica.

052387912121FFBFFF4DFA30FED8441C.taxon	diagnosis	Diagnosis. Epirhyssa lewisi may be distinguished by its relatively short ovipositor (9.2 – 12.8 mm), weak occipital carina, antenna basally yellowish, and metasomal tergites VI – VIII entirely black. In the key to Peruvian species (Gómez et al., 2015), E. lewisi goes to E. simpirae Gómez & Sääksjärvi in couplet 16, but differs by having a yellow mesosternum (as opposed to black) and by lacking a median longitudinal channel on the propodeum.	en	Zuñiga, Ronald, Hanson, Paul (2024): Two new species of Epirhyssa (Hymenoptera: Ichneumonidae: Rhyssinae) from Costa Rica.
