Figure 1 Distocambarus youngineri collected from the type locality and photographed in an aquarium. Introduction Common Name Newberry Burrowing Crayfish ( Taylor et al., 2007 ) Conservation status Endangered ( Taylor et al., 2007 ), critically imperiled in South Carolina and globally (S1, G1; South Carolina Comprehensive Wildlife Conservation Strategy 2005-2010, [SC CWCS] 2005 ). Based on the species' limited distribution (< 20,000 km 2 ) and its observed decline at population sites ( Eversole, 1995a , b , unpublished data) D. youngineri has been classified as vulnerable, VU B1b (i, iv), following IUCN (2001) . Identification The Newberry burrowing crayfish ( Fig. 1 ), Distocambarus youngineri Hobbs and Carlson, 1985 originally occured in two localities in the southwestern part of Newberry County, South Carolina. The genus Distocambarus , elevated to generic level by Hobbs and Carlson (1983) , embraces two species, D. devexus ( Hobbs, 1981 ), and D. crockeri Hobbs and Carlson, 1983 , in the subgenus Distocambarus , and three species, D. carlsoni Hobbs, 1983 , D. youngineri , and D. hunteri Fitzpatrick and Eversole, 1997 , in the subgenus Fitzcambarus . The form I male gonopod shaft of D. youngineri terminates in two elements,
