Neighbor-joining (NJ) phylogram of mitochondrial 12SrRNA . The four numbers on each branch indicate greater than 50% bootstrap support values for the branch as determined by NJ, maximum parsimony, and maximum likelihood methods, and a Bayesian clade credibility value of greater than 70% Asterisks indicate values with less than 50% bootstrap support values, less than 70% Bayesian support values, or no support. Population names are abbreviated [see Additional file 1]. Haplotype A in the D. galeata clade occurred in nine populations throughout Japan: Hrs4, Hyg5 Mie6, Ibr12, Ngn13, Fsm21, Fsm25, Ygt27, Myg29, Myg31, and Hkd61.
