(A) Distribution of mtDNA lineages of Natrix natrix in Türkiye and surrounding areas based on Asztalos et al. (2021) and their geographic (air) distances to the record from the Hakkâri Province. (B) Parsimony network for 22 ND4-tRNAs sequences of mtDNA lineage 8. Symbol sizes reflect haplotype frequencies. Small black circles are missing node haplotypes; each line connecting two haplotypes corresponds to one mutation step. The haplotype affiliation of the Hakkâri specimen (HAKZM 3/2020) is marked in red (haplotype “gn22”).
