This species occurs throughout the South Central Plains and Mississippi Alluvial Plain, ascending river and stream valleys into portions of the Interior Highlands. Isolated localities plotted by Trauth et al. (2004) in the Ouachita Mountains, northern Faulkner County, and central Independence County remain unsourced.
