Phylogenetic trees based on NT data. (A) A single MP tree constructed with un-weighted scheme (tree length = 3233; CI = 0.4930; RI = 0.5581); (B) A single MP tree constructed with six-parameter weighting scheme (tree length = 2313.3101, CI = 0.5016, RI = 0.6059); (C) ML tree (-ln L = 20990.05); (C) Bayesian tree. Numbers besides nodes indicate bootstrap values in (A), (B) and (C), but posterior probabilities in (D). Symbols indicate the taxonomic assignment of species: affinis subgroup (); pseudoobscura subgroup (); obscura subgroup (■); sinobscura subgroup (□); subobscura subgroup (); microlabis subgroup ().
