(sensu lato): a western clade including populations from the Trinity River to the drainages of Pensacola Bay, a central clade from the Choctawhatchee River to the Ochlockonee River, and an eastern clade restricted to the Suwannee River. In this hypothesis, the Eastern (Suwannee) population (hereafter referred to as the Eastern (Suwannee) assemblage, for consistency with literature) was basal and sister to a well-supported monophyletic group comprising populations from the central and western distribution (hereafter, central and western assemblages, respectively). However, because mtDNA is maternally inherited and fails to detect male-mediated dispersal,

Comparison of a neighbor-joining tree summarizing microsatellite variation (F ST values) and a parsimony tree summarizing mtDNA haplotypes presented generally similar relationships, except for the drainages of Pensacola Bay, which were described by microsatellite data as being so deeply divergent as to question their membership in either the central or western clades of Roman
