FIGURE 1. Phylogenetic relationships within the Leptophis ahaetulla Group as inferred from 1,383 bp of mitochondrial DNA from the concatenated 16S and cytochrome b genes. A 50% majority rule consensus tree from the maximum likelihood analysis is shown. Values above nodes show the parsimony followed by the maximum likelihood bootstrap support values (only values over 50% are shown). Leptophis coeruleodorsus sequences are indicated by the dark, vertical bar.
