The partial mitochondrial 12S rRNA and 16S rRNA gene sequences (440 bp and 590 bp or so, respectively were determined of the Przewalski's gazelle Procapra przewalskii , Mongolian gazelle P. gutturosa , Tibetan gazelle P. picticaudata , goitered gazelle Gazella gutturosa , saiga Saiga tatarica , Tibetan antelope Pantholops hodgsoni , and thar Hemitragus jemlahicus . The average sequence divergence for all the species studied when both rRNA genes were combined was 8.4% (±0.7%), and the divergence values ranged from 0.5% to 13.3%. The average sequence divergence values for 16S rRNA gene and for 12S rRNA gene were 9.9% (±1.1%) and 6.3% (±1.1%), respectively. The sequence divergences among species of Procapra for 16S rRNA gene and for 12S rRNA gene were 1.4%(±0.5%) and 1.1% (±0.6%), respectively. Our phylogenetic analysis revealed the monophyly of the genus Procapra and that Przewalski's gazelle is more closely related to the Mongolian gazelle than to the Tibetan gazelle. We also found that the genus Procapra is closely related to Antilopini. We argued that the critically endangered Przewalski's gazelle should be treated as a species, not a subspecies of the Tibetan gazelle, which clearly warrants more attention from conservationists.
