A new minute-size empidoid fly genus, Gondwanamyiagen. n. and two new species (Gondwanamyia chilensis Cumming & Saigusa, sp. n., Gondwanamyia zealandica Sinclair & Brooks, sp. n.) are described, illustrated, and their distributions mapped. The family and subfamily assignments remain uncertain, but features of the female terminalia potentially suggest Trichopezinae (Brachystomatidae).
