Range DescriptionThis species is endemic to the Escambia, Yellow, and Choctawhatchee River drainages in Alabama and Florida (Williams and Butler 1994, Johnson 1967). Due to recent status surveys, its historical range has been expanded (Williams et al. 2000, Blalock-Herod et al. 2005): within the Escambia River drainage, it is now known from rivers in Escambia County, Florida; Conecuh County, Crenshaw County, and Butler County, Alabama; within the Yellow River drainage, it is known from the main channel Yellow River in Okaloosa County, Florida, and Covington County, Alabama; within the Choctawhatchee River drainage, it is known from the Choctawhatchee River main stem in Washington and Holmes Counties, Florida; and a river in Geneva County, Alabama (Williams et al. 2000, Blalock-Herod et al. 2005, see USFWS 2003). Blalock-Herod et al. (2005) listed it in six historical (found in 2 of 3 recently resurveyed) and 20 new sites in the Choctawhatchee River drainage of Alabama (mostly) and Florida.
