OBSERVATIONS ON NORTH-CAROLINA CRAYFISHES (DECAPODA, CAMBARIDAE)

Cambarus (Tubericambarus) acanthura, Orconectes (Procericambarus) spinosus, and an apparently undescribed species of Orconectes (O. sp. B), are reported for the first time from North Carolina. Six additional specimens of Orconectes (Crockerinus) virginiensis are reported from the Chowan and Roanoke basins, and its range in North Carolina is clarified. Orconectes (C.) erichsonianus, for which a North Carolina locality has been published, is deleted from the State list. Cambarus (Jugicambarus) asperimanus is reported from the Watauga and New rivers in Watauga County, and localities are provided that expand its known range in the Piedmont Plateau. New locality data, distributional clarifications, or natural history notes are provided for Cambarus (Depressicambarus) latimanus, C. (D.) reduncus, Cambarus (Jugicambarus) carolinus, C. (J.) dubius, C. (J.) nodosus, Cambarus (Puncticambarus) georgiae, C. (P.) parrishi, C. (P.) reburrus, Procambarus (Ortmannicus) medialis, P. (O.) pearsei, and P. (O.) plumimanus. A blue specimen of C. latimanus is reported from the Neuse River basin. The North Carolina crayfish fauna is correlated with the State's major river basins and physiographic provinces.
