The complete mitochondrial genome was sequenced from a viviparous toad-headed agama, Phrynocephalus forsythii, which is endemic to the Taklamakan Desert. The mitogenome sequence was 17,542 bp in size, containing 13 protein-coding genes, 22 tRNA genes, two rRNA genes and a control region (D-loop). The gene arrangement and composition of P. forsythii is identical to the mitogenome of P. theobaldi in that tRNA-Pro was translocated immediately downstream of tRNA-Phe. The D-loop comprised two parts, one existing between tRNA-Thr and tRNA-Phe, and another containing 12 copies of 36-bp tandem repeats inserting between tRNAPro and 12S rRNA. The complete mitogenome sequence of P. forsythii may provide fundamental data for unveiling the phylogenetic origin and adaptive evolution related to Phrynocephalus viviparity.
