摘要在法国罗布什河畔普罗旺斯艾克斯区渐新世发现了Saffo属和Epiacechna属的新种。Saffo leGrand i n.sp.是这一新的非洲属的第三个化石代表，即Epieschna赝oheros n.sp.是这一近期北美属的第五个化石物种。英国始新世的Trieschna Gossi、哈萨克斯坦晚渐新世的Epacantha manma和中国渐新世的Mediacechna Matutina被认为是Epieschna的物种，而Trieschna Campion 1916年、Medieschna Zhang 1989和Epacantha Martynov 1929三个化石属是Epieschna的异名。关系密切的乌玛属和萨福属生活在西非温暖潮湿的森林中。它们在法国的两个渐新世沉积中的存在支持了Armissan(法国Aude)和Aix-en-Provence的温暖潮湿古环境的假说。
Abstract New species of the genera Sapho and Epiaeschna are recorded in the Oligocene of Aix- en-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 fifth fossil species of this recent North American genus. The fossil species Triaeschna gossi from the Eocene of England, Epacantha magnifica from the Late Oligocene of Kazakhstan, and Mediaeschna matutina from the Oligocene of China, are considered 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.
