t Identifying the origin of a biological invasion is critical for controlling the invaders. To explore the genetic diversity and identify the source region of introductions of Pelophylax nigromaculatus to the Xinjiang Uyghur Autonomous Region, we sequenced 695 bp of the mitochondrial Cyt b gene in 140 individuals of P. nigromaculatus and identified 42 haplotypes in Heilongjiang, Beijing, Jiangsu, Shaanxi, Zhejiang provinces, Chongqing and the Xinjiang Uyghur Autonomous Region. We detected only four mitochondrial haplotypes in 20 specimens from Yining city in Ili Kazak Autonomous Prefecture. We traced the origin ofYining P. nigromaculatus to the Beijing and Chongqing area. Our results extend the known distribution range of this species in Asia.
