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.
