Oenomaus atena

Oenomaus atena is a species of butterfly of the Lycaenidae family. It is widely distributed in lowland in Costa Rica, Panama, western Ecuador, French Guiana, Venezuela, Peru and Brazil. Most species with an atena-like ventral wing pattern have historically been identified as O. atena, which means that virtually all literature records for this species from before 2005 are unreliable.
