Range Description

This species ranges from the Nueces and Guadalupe rivers of southern Texas north to the Trinity River drainage of the Dallas area and the Red River (Howells et al. 1996), then eastward to western Mississippi (Vidrine 1993) with populations in southern Arkansas (Harris and Gordon 1990). In Louisiana, this species is known from dozens of sites across the state with concentrations in western Louisiana where it is extremely common in creeks and medium sized streams (it is the most abundant species in the headwater creeks of the Calcasieu River system) (Vidrine 1993). In Mississippi, it is only known from the Big Black River and Yazoo River drainages where it is a species of concern (Jones et al. 2005). The taxonomic status of populations in southeastern Oklahoma remains unclear, but may include this species (Branson and Branson 1984).
