Discussion: Species-groups with potential subgeneric names, based on Groves and Willoughby (1981), are as follows: E. asinus or Asinus group; E. caballus or nominate Equus group (synonym: Caballus ); E. grevyi or Dolichohippus group (synonyms: Grevya , Ludolphozecora , Megacephalon , and Megacephalonella ); E. hemionus or Hemionus group (synonyms: Asinohippus , Hemippus , Microhippus and Onager ), including also E. kiang ; E. quagga or Quagga group (synonyms: Pseudoquagga , Quaggoides , and Zebra ), including also E. burchellii ; and E. zebra or Hippotigris group. Earliest generic name for the E. quagga group ( Zebra J. A. Allen, 1909 ) is preoccupied and next available name († Kraterohippus van Hoepen, 1930 ) would have priority over Quagga Shortridge, 1934 if these nominal genera were treated as valid taxa.
