Abstract: Yuanqu Basin is the place where Chinese eomoropid fossils were found for the first time (Zdan-sky, 1930). New finds collected in recent years add not only new material of old species but a new taxon. Two genera and three species, including a new one, from two horizons are described in the present paper.
