To evaluate the genetic characteristics of the Reeve's pond turtle (Mauremys reevesii) in Kyushu and adjacent islands, mitochondrial DNA (mtDNA) control region of five individuals from northern Kyushu (Fukuoka and Kumamoto-Amakusa) and one from each of Iki and Tsushima Islands in this species was sequenced. Phylogenetic analysis of mtDNA haplotypes revealed that 5 of the 7 individuals belonged to Group A. The remaining two individuals belonged to Group B, which was clearly considered to be a non-native lineage. One individual of Tsushima Island, which is close to the Korean Peninsula, belonged to Group A, suggesting that the Tsushima population of M. reevesii is native. Considering the close biogeographical relationship between northern Kyushu and the Korean Peninsula, it also cannot be ruled out the possibility that the Group A individuals in Kyushu are native. To determine the relevant conservation strategy of M. reevesii in north Kyushu and adjacent islands, a more detailed analysis of the genetic structure of this species is required.
