AbstractA new species of Entheus is described from the Chocó region in northern Ecuador. Entheus warreni n. sp. belongs to the E. matho group and differs from other congeners by its distinctive wing pattern and subtle features in genitalia. Taxonomic problems with Entheus caused by the existence of cryptic species and extreme sexual dimorphism are discussed.
