Habitat:
This species occurs within and adjacent to seepage streams in steep-sided ravines within slope forests. It is sometimes also found in mucky floodplain and bottomland forests. This species relies on good water quality. Undisturbed, pristine ravines and seepage streams are ideal habitats for this species. It uses logs, rocks, leaf-litter and leaf packs for cover, and also takes refuge in friable stream banks (Means and Karlin 1989). Eggs are attached in clusters to the under-surface of twigs or small logs or rocks and immersed in flowing water; larvae are found in very shallow water trickling through decomposing litter on saturated sites adjacent to larger brooks, on sandy or organic substrates (Means and Karlin 1989).

Range:
This species is endemic to the lower southeastern states of Alabama, Florida and Georgia in the United States of America. It is known from the watersheds of the Upper Choctawhatchee River in Alabama, the Upper Apalachicola River, Upper Ochlockonee River and Lower Chipola River in Florida, and the Chattahoochee River and Lower Flint River in Georgia. In the Lower Chattahoochee River drainage basin, it occurs from the Fall Line at Columbus, Georgia, south to the northern edge of the Dougherty Plain physiographic region of Georgia and Alabama to about the Miller-Early county line in Georgia. It is abundant in ravines along the eastern valley wall of the Apalachicola River downriver from the town of Chattahoochee, Florida, to Outside Lake near the town of Estiffanulga; it ranges to about 50 km upstream from Chattahoochee along the Pelham Escarpment. This species is common in ravines along the Ochlockonee River and its two major tributaries, Little River and Telogia Creek, in the Tallahassee Red Hills of Florida. A few subpopulations are known from the lower Chipola River in ravines above its confluence with the Apalachicola River (Means 1993). Subpopulations probably occur in most/all suitable microhabitats within the range (Means and Karlin 1989). It ranges between sea level and approximately 500 m asl.

Conservation:
Conservation Actions In-Place
This species occurs in several managed areas, and one-third of its known occurrences are protected. It is considered potentially protected in Torreya State Park and the Apalachicola Bluffs and Ravines Preserve of The Nature Conservancy in Florida, and Kolomoki Mounds State Park in Georgia (Green et al. 2014). 

Conservation Needed
The recommended conservation measures for this species include the prevention of pollution, siltation, and impoundment, maintenance of forested slopes above streams, elimination of feral hogs when present, and protection via acquisition or easement of any occurrences not yet within managed areas. Programs aimed at increasing awareness and public education are also needed.

Research Needed
More information is needed on this species' distribution, population status, and ecology. Specifically, additional ravines within this species' range should be surveyed, and the upstream and downstream extent of each occurrence should be determined.
