This species complex occurs throughout the Ouachita Mountains, with some expansion into more mountainous regions of the Arkansas Valley south of the Arkansas River. One locality north of the Arkanasas River in northern Faulkner County, but still an extension of the Ouachita Mountains, has been confirmed by genetic analysis (R. M. Bonett, pers. comm.). It has been found sympatrically with E. paludicola in the vicinity of Caddo Valley, Clark County (K. J. Irwin, pers. comm.), so specimens from this area warrant close examination.
