The genus Hainina ("from Hainin") was named by Vianey-Liaud M. in 1979. This genus was originally referred to as Cimolomyidae. "We assign Hainina to the Kogaionidae (superfamily incertae sedis); it differs from Kogaionon in having ornamented enamel, while the enamel is smooth in Kogaionon".[1] Material has also been reported from the Upper Cretaceous of Romania.
