Abstract

The Cumberland Plateau and Cumberland Mountains sections (collectively referred to here as the Cumberlands) of the Appalachian Plateaus province extend in a northeast-southwest direction across the states of Kentucky, Tennessee and Alabama, touching portions of Virginia and Georgia. The Cumberlands are primarily drained by the Cumberland, Tennessee and Black Warrior River systems; however, tributaries of the Big Sandy, Coosa and Tombigbee rivers also arise within these geomorphic sections. Three nominal species of Procambarus and eleven of Orconectes occur in the Cumberlands as follows: P. a. acutus, P. clarkii, P. lophotus, O. a. australis, O. a. packardi, O. erichsonianus, O. forceps, O. mirus, O. perfectus, O. placidus, O. putnami, O. rusticus, O. spinosus, O. validus and O. virilis. The literature review presents a summary of the systematic and zoogeographical research concerning crayfish records from the Cumberlands. The annotated list gives the range and habitat of these species in the Cumberlands with notes on their current systematic and geographical status. Orconectes juvenilis (Hagen, 1870) is reduced to junior synonomy of O. rusticus (Girard, 1852). Orconectes putnami and O. spinosus are shown to be valid species separate from O. juvenilis (=rusticus).
