This species has been assessed as Endangered under criterion B1ab(v). This species has an extremely restricted extent of occurrence of 300 km2, and is known from only 4 locations. There is an ongoing decline in the number of mature individuals of this species, though the precise reasons for this are unclear. A number of potential threats have been proposed including close vicinity to urban development, roads and alteration of the groundwater supply to the caves. Further research is needed on the precise nature of threats before appropriate conservation strategies can be devised.
|Range Description:||This species is endemic to Marshall county, Alabama. It is distributed northwest and downstream of the Guntersville Dam, along both sides of the Tennessee River (Buhay and Crandall 2009). Its range is restricted by two towns, Mount St. Olive and Cushion along the Paint Rock River, to the southwest and eastern sides of the Tennessee River (Buhay and Crandall 2009). This species is known from 4 caves within its range. Extensive surveys in surrounding areas have failed to find further localities (Buhay et al. 2007).|
Native:United States (Alabama)

|Population:||This species is declining in numbers (Buhay et al. 2007).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is cave dwelling and is found in streams less than one meter wide (Buhay and Crandall 2009).|
|Major Threat(s):||There are a number of potential threats to this species including close vicinity to urban development and pollution of the freshwater aquifer, vicinity to roads, and alteration of the water table through damming of rivers (Buhay and Crandall 2009). There is a continuing decline in the number of mature individuals of this species (Buhay et al. 2007).|
|Conservation Actions:||There are no species-specific conservation measures in place for this species. Further research is required to determine the exact nature of the threats driving the decline in the number of mature individuals.|
