Meriones libycus belongs to the genus Meriones in Gerbillinae, its complete mitochondrial genome is 16,341 bp in length. The heavy strand contains 32.8% A, 13.1% G, 25.3% C, 28.8% T, protein-coding genes approximately accounting for 69.54%. Results of phylogenetic analysis showed that M. libycus and Meriones unguiculatus were clustered together, and it was consistent with that of primary morphological taxonomy. This study verifies the evolutionary status of M. libycus in Meriones at the molecular level. The mitochondrial genome would be a significant supplement for the gene pool of Rodentia and the conclusion of phylogenetic analysis could be an important molecular evidence for the classification of Gerbillinae.
