Iophanus is a monotypic butterfly genus in the family Lycaenidae described by Max Wilhelm Karl Draudt in 1920. The single species of this genus, Iophanus pyrrhias, the Guatemalan copper,[1] was described by Frederick DuCane Godman and Osbert Salvin in 1887. It is found in Guatemala, the highlands of Chiapas, Mexico, and apparently in a few other areas of the Neotropical realm.[2]
Iophanus pyrrhias is a small butterfly. The hindwing ends in a short tail. The upperside is brown, with a distinct purple-metallic sheen on the males. The females are dull brown except for an iridescent blue field at the base of the forewings. Along the rear edge is an orange zigzag. The underside of the forewings is dull yellow with brown edges and brown stripes; the underside of the hindwings is brown with some darker markings.
