This species has been recorded from lowlands of the South Central Plains west of the Saline River and the Mississippi Alluvial Plain east of the White and Black rivers. Some ascension into lower elevations of the southern Ouachita Mountains occurs along the Caddo River valley. Some records have raised questions due to identifications based on early life stages (eggs and larvae), particularly from the Ouachita Mountains (HSU 1640 from 2012 and ANHC AAAAA01120*003 from 1977) and from the range periphery in Dallas County (ANHC AAAAA01120*002 from 1978).
