FIGURE 2. A, molecular phylogeny of Metasiro COI sequences, made ultrametric using a relaxed clock, showing the four putative species from the GMYC model (red clades above the dashed red line); B, lineage-through-time plot for Metasiro diversification, the red line indicating the inferred time of rapid within-species COI diversification resulting from a singlethreshold analysis. Time for all plots is expressed as the proportion of time since the present to the root. Specimens of M. americanus collected from the Apalachicola River region and Florida Caverns are colored by location.

FIGURE 1. Unrooted phylogeny for all Metasiro COI sequences, found under parsimony in POY and showing parsimony branch lengths. Insets A, B, and C show the locations of unique nucleotides (smaller, lower triangles) and amino acids (larger, upper triangles) along the 769 bp COI fragment. The frequencies of corrected pairwise divergences are shown in inset D and are divided by the type of comparison: solid black for intraspecific distances, dashed black for interspecific distances, and dashed gray for distances among widespread populations of M. americanus in the Florida panhandle.
