Equinae is a subfamily of the family Equidae, which live worldwide (except Indonesia and Australia) from the Hemingfordian stage of the Early Miocene to present (20.6—0 mya) and in existence for approximately 20.6 million years.[1]


Equinae was named by Steinmann and Döderlein in 1890 and was considered monophyletic by MacFadden (1998).[2]


The subfamily contains two tribes the Equini and the Hipparionini as well as two unplaced genera Merychippus and Scaphohippus.
