BI tree of the concatenated mitochondrial sequences ( 12S , 16S and COI ). Posterior probabilities and ML bootstrap values are provided for all nodes above species level. The scale bar indicates the expected number of substitutions per site according to the models of sequence evolution applied. The black and grey dots indicate nodes with high BI posterior probabilities and ML bootstrap values (see Figure). The colors of the specimen labels correspond to those used in Figures 4, 7 and 9.
