FIGURE 5. Maximum Likelihood tree of partial COI sequences from analysis of 17 unique sequences (599 bp) retrieved in this study. The species and locations of Cambarus sp. are listed in Table 3. The COI gene of C. bartonii was used as the outgroup. Accession numbers of sequences are indicated in parentheses. Bootstrap values from 1,000 replicates are indicated at the nodes of branches (if>50). The scale bar represents the number of nucleotide changes.
