Early Eocene mimotonids of Kyrgyzstan and the problem of Mixodontia
Alexander O. Averianov
The Mimotonidae is a sister group for Lagomorpha that lacks important lagomorphs synapomorphy in the structure of p3. The family consists of six genera (Mimotona, Gomphos, Zagmys, Mimolagus, and two newly described genera).
Together with Eurymylidae they form an evolutionary grade of ancient Glires and it is argued that the concept of Mixodontia is valid. Two new mimotonids, Anatolmylus rozhdestuenskii gen. n., sp. n. and Aktashmys montealbus gen. n., sp. n. from the latest Early Eocene (late Ypresian) of Andarak 2 locality (Kyrgyzstan) are described.
Key words: Mammalia, Glires, Mixodontia, Early Eocene, Central Asia.
