Diaethria is a brush-footed butterfly genus found in the Neotropical realm, ranging from Mexico to Paraguay.

Species in this genus are commonly called eighty-eights like the related genera Callicore and Perisama, in reference to the characteristic patterns on the hindwing undersides of many. In Diaethria, the pattern consists of black dots surrounded by concentric white and black lines, and typically looks like the numbers "88" or "89".
