This species inhabits the western half of the Caddo Mountain subrange within the greater Ouachita Mountains, with southward expansion along the Cossatot River to at least Gillham Lake, Howard County. Shepard and Burbrink (2011) identified four highly divergent, geographically distinct lineages (inset): Brushy Creek (■), Cossatot/Little Missouri Rivers (■), Lower Caddo River (■), and Upper Caddo River (■). However, these have not been proposed for species status. Trauth et al. (2004) plotted some questionable localities which remain unsourced.
