Comments: Known Alabama populations seem to be small. Back in 1988, catch rates in exemplary Alabama sites were 25 per hour. A total of 30 subpopulations were known in 1996. Large lots can be found representing the Choctawhatchee system in Florida in museum collections dating to the 1930's. Recent surveys (e.g., Williams et al., 2000, Blalock et al., 1998) did not include abundance information. Pilarczyk et al. (2006) recorded recent collections (in 2004) of this species following surveys of 24 sites at 11 sites.
