Isostola divisa (Walker, 1854)

Fig. 2 N

Remarks.

This species does not exhibit sexual dimorphism. The wing pattern suggests that these moths participate in mimicry rings with glasswing Ithomiini butterflies ( Nymphalidae ). The available information is restricted to the original description and its inclusion in faunal survey lists. While this species is commonly found in Central America and the Amazon biome, Ferro (2007) documented its presence in the Brazilian Cerrado.

Material examined.

1 male, Costa Rica, Guapiles.
