Bayesian gene trees of mitochondrial cytochrome b (cyt-b) gene from Robertson et al. [19][A] and the present study [B], and Bayesian gene tree of non-coding region (NCR) by the present study [C]. The tree arrangement from Robertson et al. [19] has been slightly modified. Left numbers along branches represent the Bayesian posterior probabilities (BPP) and right numbers represent bootstrap proportions (BSP) derived from the parsimony analysis. The detailed information of specimens that were sequenced is listed in Table 1. *A unisexual-like cyt-b numt likely exists in A. barbouri specimens JPB34337, JPB34342, JPB34343 and JPB34356 [A] so they were grouped within the unisexual clade.
