New species of the genera Sapho and Epiaeschna are recorded in the Oligocene of Aixen-Provence, Bouches-du-Rhône, France. Sapho legrandi n. sp. is the third fossil representative of this recent African genus and Epiaeschna pseudoheros n. sp. is the fi fth fossil species of this recent North American genus. The fossil species Triaeschna gossi from the Eocene of England, Epacantha magnifi ca from the Late Oligocene of Kazakhstan, and Mediaeschna matutina from the Oligocene of China, are
more » ... species of Epiaeschna and the three fossil genera Triaeschna Campion 1916, Mediaeschna Zhang 1989, and Epacantha Martynov 1929 are synonymized with Epiaeschna. The closely related genera Umma and Sapho inhabit warm humid forests of Western Africa. Their presence in two Oligocene deposits of France supports the hypothesis of a warm humid palaeoenvironment for Armissan (Aude, France), and Aix-en-Provence.
