Abstract:
Spatial distributions of South Carolina crayfish were geo-referenced for over 3900 museum and collection records. Collection site records are not evenly distributed across the state; some parts of the state are poorly represented while other parts have a disproportionate number of collection records. Currently, 38 described species in five genera occur in the state of which eight are endemic species and one an introduced species. Cambarus latimanus and Procambarus troglodytes were the two most widely distributed species while the four Distocambarus species have the narrowest distributions. Most of the records of Cambarus were from above the fall line, whereas, Procambarus records occurred mostly below the fall line; the exceptions were for the primary burrowers C. diogenes and C. reflexus and the stream dwelling P. spiculifer. Crayfish species were rarely restricted to single river systems or watershed units. The 27% of South Carolina crayfish species considered in the greatest conservation need included all four Distocambarus species, four Cambarus species and two Procambarus species. Conservation status of the South Carolina crayfish will require updating because of the potential taxonomic problems of species complexes, new species descriptions and limited distribution records for some species.
