The posterior ridge is moderately inflated and ends abruptly with little development of the posterior slope at the dorsum of the shell. The periostracum is yellow to yellow-brown with occasional green rays or spots on the umbo in young specimens (68 FR 14752).The species historical range included Alabama, Georgia, Mississippi, Tennessee.

Reproductive Strategy
Gravid southern clubshell females with mature glochidia have been collected in June and July. Glochidia are released in well formed conglutinates orange or white in coloration (Haag and Warren 2001). Blacktail shiner (Cyprinella venusta), Alabama shiner (C. callistia), and tricolor shiner (C. trichroistia) have been identified as fish host (Haag and Warren 2001, P. Johnson pers. comm. 2002). However, a small host trial by the AABC in 2010 showed the blacktail shiner to be poor hosts (Johnson 2018).
