Hista hegemon is a moth in the Castniidae family. It is found in south-eastern Brazil.
The length of the forewings is 39 mm for males and 53 mm for females. The maculae on the forewings are slightly darker than the ground colour.

The specific epithet is derived from the Greek word hegemon (meaning "leader").
