Ulanodon,a new name for the Hyracodontid Ulania Qi,1990(Perissodactyla,Mammalia)

Qi(1990a)named a new hyracodontid genus Ulania from the Middle Eocene deposits of Nei Mongol(Inner Mongolia),China.However,the generic name has been preoccupied by Ulania Lin&Zhang,1979,a Cambrian trilobite(Zhu,et al.,1979).We therefore propose a new generic name Ulanodon nom.nov.to replace Ulania Qi,1990.
