Figure 2. Bayesian phylogenetic tree based on partial sequences from the mitochondrial COI gene that was generated using the software program MrBayes and using the HKY+G model of sequence evolution. The tree depicts relationships among Cambarus loughmani sp. nov. (in bold) and several other species formerly considered part of the C. dubius species complex. Also represented are other related burrowing crayfish from the genus Cambarus as well as additional taxa from two other genera that are included as outgroups. Numbers at the nodes of the tree indicate Bayesian posterior probabilities.
