Episageceratinae is a subfamily of the Medlicottiidae, a family of prolecanitid ammonites. The Episageceratinae, proposed by Ruzhencev, 1956, is based on the genus Episageceras previously included in the subfamily Medlicottiinae and lived during Late Permian and Early Triassic times.So far only three confirmed genera are included: Episageceras, Latisageceras, and Nodosageceras. J.P Smith, 1932 (USGS PP 167) included Episageceras in the Pronoritidae (p. 36) as a subgenus of Medlicottia.
