North Carolina Crayfishes 89 



North Carolina was not included in his statement of the range of this 

 putative subspecies (Hobbs 1989:14). We have opted to omit it as a 

 member of the North Carolina cambarid fauna until specific evidence 

 appears to support its inclusion. 



Four described species are North Carolina endemics: Cambarus 

 {Depressicambarus) catagius Hobbs and Perkins, of the upper Cape 

 Fear River basin; Cambarus (Puncticambarus) reburrus Prins, of the 

 French Broad and Savannah basins; Procambarus (Ortmannicus) 

 medialis Hobbs, of the Neuse and Tar-Pamlico basins; and Procambarus 

 {Ortmannicus) plumimanus Hobbs and Walton, of the Northeast 

 Cape Fear and New (White Oak) basins, which, as we explain later, 

 may be expanding its range into the lower Neuse basin. The undescribed 

 Orconectes sp. A is another North Carolina endemic, found only in 

 the Neuse and Tar-Pamlico basins. 



This article adds two described and one undescribed native species 

 to the State list, provides additional distributional and natural history 

 information for them and 13 other species, deletes a species for which 

 a North Carolina locality has been published, correlates the State's 

 crayfish fauna with its major hydrologic units, and summarizes the 

 distribution of this fauna in the State's three major physiographic 

 provinces. 



Abbreviations used are as follows. SR = secondary road (formerly 

 CR for county road); NC = North Carolina state highway; US = United 

 States highway (an A after the number means alternate highway); I = 

 interstate highway; FRS = United States Forest Service Road; cntr = 

 center of town or city; NCSM C- = crustacean collections, North 

 Carolina State Museum of Natural Sciences, Raleigh; USNM = collections, 

 U. S. National Museum of Natural History, Smithsonian Institution, 

 Washington, D. C. Collector's names are given in first usage, initials 

 thereafter. 



Cambarus {Depressicambarus) latimanus (LeConte) 

 Hobbs (1981:120), reporting observations made in a thesis by 

 J. L. Boyce (1969), stated that in Yellow River, Georgia, C. latimanus 

 "becomes relatively inactive during December, January, and 

 February," Hobbs (1981:119) also provided monthly capture data for 

 a large number of specimens that suggested the same thing: 77 collected 

 in November, five in December, 21 in January, and none in February, 

 as opposed to 164 in March, 1,079 in April, and relatively 

 high numbers in most other months. These kinds of collecting data, 

 however, can be more a reflection of seasonal activities of the collectors 

 than of the collected. If we can equate "activity" with "catchability,"
