NeighborNet using concatenated sequences of nine nuclear loci (6071 bp; 40 individuals) with up to 5% missing data. The three subgenera are indicated by different colors. The terminal clusters containing species of the subgenus Chelodina sensu stricto (left) and Chelydera (right) are enlarged, showing the individual alleles (1, 2 following the sample codes; File S1). Note that alleles of the same individual may occur in different subclusters. Putative Chelodina kurrichalpongo (with question marks) from the Ord River floodplain are only indicated by their GK codes. Abbreviations: NT – Northern Territory, WA – Western Australia. Alleles from Western Australian turtles color-coded to highlight different taxa. Inset right shows putative C. kurrichalpongo (GK37 = WAM R150821, Parry Creek, WA).
