Most of the remains of the small pleistocene equid of Binagady usually considered as an E. hydruntinusmay be referred to a new subspecies, E. hemionus binagadensis. A few teeth and bones really resemble E. hydruntinus. In the holocene of the plain of Qazvin, beside numerous remains of an average Hemione, there are several first phalanges similar to those of E. hemionus binagadensis, and several teeth similar to those of E. hydruntinus. We decided to consider them as representative of separate taxa. If, however, they are just variations of E. hemionus, our insight of E. hydruntinus has to be modified in one of two ways: either E. hydruntinus is a Hemione (not an Ass, nor a kind of E. stenonis or Zebra), or the “specific” characters of E. hydruntinus result of a parallel evolution.
