Research output: Contribution to journalArticlepeer-review

Abstract

A new crayfish, Cambarus clivosus, is described from the Caney Fork and Stones river drainages of central Tennessee and is placed in the subgenus Jugicambarus. The species occurs in small, high gradient, seep-fed creeks with substrates of chert, limestone, and shale. Cambarus clivosus differs from all other members of the subgenus Jugicambarus in possessing a single row of tubercles along the mesial margin of the palm of the chela, an obtuse suborbital angle, a central projection with a subapical notch, and strongly converging rostral margins.
