distributed variously from Mexico to Argentina and Bolivia.
The species vary
considerably in appearance - e.g. the upperside of
eudocia is bright orange with a broad
black apex within which is a patch of metallic violet-blue. At the
opposite extreme, nycteis is pale
brown, mottled heavily with blackish, and has a prominent
double-pupilled ocellus at the apex of the hindwing. The vast
majority of species including eurygonina
are black on the upperside, with a dazzling metallic blue sheen
across the basal half of the forewings and over the entire surface
of the hindwings.
The undersides of
Theope are typically either plain white
with a series of tiny submarginal spots, or are cryptically marked
in shades of brown. The latter group resemble small dead leaves, and
have falcate forewings. The double-banded underside of
eurygonina is unique in the genus.
Colombian specimens are more strongly marked, and have small but
prominent submarginal ocelli.

occurs over much of South America.
This species is found in rainforest at altitudes between about
