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.

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.
