This powerfully built crayfish is usually olive-tan or reddish brown, without prominent spots or blotches. A narrow blackish band is present at the junction of the carapace and abdomen. The carapace is broad and dorsally flattened (as if pushed down on from above) and is separated at its middle by a space (areola). In the upper White River drainage, Hubbs' crayfish are bright orange-red. Hubbs’ crayfish is distinguished from other stream crayfish within its range by the broad, dorsally flattened carapace, unusually powerful pincers, and nearly uniform color without spots or blotches.
