Range Description

This species is known from several small tributaries of Black Creek in Clay County, a tributary to the St. Johns River in Duval County, Florida (Franz and Franz 1979). It is also reported from Putnam County (NatureServe 2009), in the upper Etoniah Creek system (P. Moler pers. comm. 2010). It is known from three stream systems (Black and Etoniah creeks, and a small stream near Fort Caroline). There have been many collecting sites (over 30, mostly in Black Creek) within these systems. In addition, potential gene flow probably occurs among most or all sites within each system (K. Crandall pers. comm. 2009). This species has a distribution of approximately 1,600 km.
