Cambarus (Puncticambarus) aldermanorum is a new species of crayfish that appears to be endemic to the lower Catawba and Saluda river basins in the Piedmont Plateau of South Carolina Morphologically, it is most similar to C (P) hobbsorum and C (P) hystricosus It differs from both species in having a long, narrow, lanceolate rostrum, and in lacking a proximomesial tubercle or spine on the ventral surface of the carpus It further differs from C (P) hobbsorum in having hepatic spines, in other aspects of spination, and in having a broader areola Cambarus (P) spicatus of the Broad River basin is another very spinose crayfish that bears some resemblances to C (P) aldermanorum, from which it differs in having a broader rostrum with a very short acumen that is delineated at its base by marginal spines or tubercles, and a much broader, more punctate areola
