Actually, according to (Groves & Grubb 2011), this taxon is still considered a subspecies of Gazelle dorcas. Only ssp. pelzelnii was split off and elevated to full species level.
@UngulateNerd92 Splitting of pelzelnii would leave Dorcas gazelle paraphyletic, so that is no valid option. Genetic research does not support splitting Dorcas gazelle and even does not indicate subspecies...
