Hi, i have a synonyms' doubt with this genera.

- Old keys separated E. festiva and E. histrio with the rounded shape of the end of the central stripe of thorax of E. festiva. (not M. Ackland's new ones, so maybe thorax's pattern is not reliable (?))
- I´m not sure if E. festiva and E. hilaris are synonyms
- Fauna E. accepts them as 2 species
- there are pics in the gallery with the 2 names
- M. Ackland keys' don´t include E. hilaris, but these keys are for British Anthos
- Fauna E. says them both (hilaris and festiva) occur in UK
¿?¿?¿? :|

Any help is welcome
