Global Range: (1000-5000 square km (about 400-2000 square miles)) This is a Mobile River and Alabama River endemic, including the Conasauga River in Alabama, Tennessee, and Georgia, where it appears to be restricted to eastern reaches; and is extant in widely scattered, isolated locations (Mirarchi et al., 2004; Simpson, 1914; Parmalee and Bogan, 1998). In the Coosa River basin in Georgia, it is known historically from the Coosa, Etowah, Oostanaula, and Conasauga River drainages (Williams and Hughes, 1998). According to Parmalee and Bogan (1998), it just barely gets over the border in Tennessee in the Conasauga River in Polk Co. It also occurs in the Tombigbee River drainage, Mississippi (Jones et al., 2005). Williams et al. (2008) confined the distribution of Strophitus connasaugaensis to eastern drainages of the Mobile Basin, and that of Strophitus subvexus to the Tombigbee and Black Warrior River drainages, however, individuals of each species may be found within the range of the other so it is unclear if the two species occur sympatrically or not.
