The mountain zebra (''Equus zebra'') is a threatened species in the family Equidae. It is native to south-western Angola, Namibia and South Africa. ==Taxonomy== The mountain zebra comprises two subspecies: * Cape mountain zebra (''Equus zebra zebra'') * Hartmann's mountain zebra (''Equus zebra hartmannae'') In 2004, C. P. Groves and C. H. Bell investigated the taxonomy of the zebras (genus ''Equus'', subgenus ''Hippotigris''). They concluded that the mountain zebra (''Equus zebra zebra'') and Hartmann's mountain zebra (''Equus zebra hartmannea'') are distinct, and suggested that the two would be better classified as separate species, ''Equus zebra'' and ''Equus hartmannae''. However, in a sexual genetic study that included 295 mountain zebra specimens, Moodley and Harley (2005) found nothing to support the separation of the two mountain zebra populations into separate species. They concluded that the Cape mountain zebra and Hartmann's mountain zebra should remain as subspecies.〔Moodley, Y. & Harley, E. H. 2005 Population structuring in mountain zebras (Equus zebra): the molecular consequences of divergent demographic histories. ''Conservation Genetics'' 6: 953–968.〕 This is consistent with the third edition of ''Mammal Species of the World'' (2005), which lists the mountain zebra as a single species (''Equus zebra'') with two subspecies.〔Wilson, Don E. & Reeder, DeeAnn M.
