Identification. This species belongs to the Cophysa group, which comprises 4 species with the common char- acteristic of having 2 oblique pale lateral bands on the synthorax. Tramea cophysa can be distinguished from other species of the Cophysa group by its dark brown to blackish basal spot of the hind wings; this spot extends to the CuP at most and usually there is no trace of it on fore wings. The dorsal portion of the frons is entirely metallic violet in males, and in females there is a posterior broad metallic violet stripe ( De Marmels and Rácenis 1982).
