National Range: "appears to be endemic to the First Broad River subdrainage of the upper Broad River basin of North Carolina" (Cooper 2000b)
NC Physiographic Region(s): western piedmont
River Basin(s): upper Broad
Adult Habitat: Lotic systems, small to medium streams, similar to C. (C.) bartonii
Reproductive Season: early June, late September, late November
Species associates: C. (J.) asperimanus, C. (P.) sp. C, and C.(P.) spicatus
Conservation status: undetermined because it was only recently described
Identification and Illustration reference: Cooper 2000b
- body shape: slightly dorsoventrally flattened
- coloration: variable – either solid or with saddle pattern and mottling; shades of brown, reddish-brown, and cream, "from greenish-brown to grayish-tan, with some juveniles approaching orangeish tan" (Cooper 2000b)
- spines: cervical spines absent but may be cervical tubercle(s); branchiostegal spines weak (if present); cephalic spine or tubercle absent
- rostrum: with subparallel margins, either blunt or converging acuminately to apex but not abnormally long (somewhat squarish); no marginal spines, and corneous tubercle at apex; possibly excavate or ladel-like dorsally
- areola: medium-wide in width
- chelae: generally smooth and large; with one row of adpressed tubercles along mesial margin of palm; moderately developed dorsolongitudinal ridges on fingers; slight pinch both dorsally and ventrally at base of fixed finger (similar to Puncticambarus subgenus); fingers may be gaping in large adults (particularly form I males)
- other characteristics: suborbital angle acute or nearly so
- form I male gonopod: corneous central projection with 90 degree mesial bend in the caudal portion; mesial process bulbous and tapering to point
most closely related to C. bartonii
