The Neotropical window fly genus Heteromphrale Kröber, 1937 is revised. Two previously described species (Heteromphrale chilensis (Kröber, 1937) and Heteromphrale cyanops (Edwards, 1932)) are redescribed while a new species (Heteromphrale blancasp. n.) is described from Argentina. The male of Heteromphrale chilensis and female of Heteromphrale cyanops are described and figured for the first time, and a key to species is presented.
