^aPIC, parsimony-informative character (i.e., shared derived nucleotide position or synapomorphy).

^bAUT, autapomorphy or a derived character unique to a particular taxon (i.e., not parsimony informative).

^cMPT, most parsimonious tree (i.e., shortest tree inferred from the DNA sequence data).

^dCI, consistency index. This index provides a metric of how much noise is in a data set. The CI is calculated by dividing the minimum possible number of steps by the observed number of steps.

^eRI, retention index. Like the CI, this metric provides a measure of how much noise is in a data set. Unlike the CI, the RI measures the amount of parsimony-informative characters from a data set that are reflected in the phylogenetic tree.

^fNinety-two ambiguously aligned positions were excluded from the EF-1α partition.

^gRegion PCR amplified by primers 5f2 and 7cr (Table 2).

^hRegion PCR amplified by primers 7cf and 11ar (Table 2).
