Distributions of two species of fairy shrimps (Crustacea: Branchiopoda: Anostraca) and two species of clam shrimps (Crustacea: Branchiopoda: Laevicaudata and Spinicaudata; formerly Conchostraca) in Carolina bays and other wetland ponds are reported for the Atlantic Coastal Plain province of South Carolina. The distributions are based on extensive sampling of 123 ponds at 11 sites in 10 counties. The fairy shrimp Streptocephalus sealii, which was common (28 ponds), has been previously published as a state occurrence. Here, we present new county occurrences. The other fairy shrimp, Eubranchipus moorei, which was uncommon (3 ponds), has not previously been reported for the state, nor has either of the clam shrimps, Limnadia lenticularis, which was uncommon (3 ponds), and Lynceus gracilicornis, which was common (17 ponds).
