Abstract
The five southeastern (United States) crayfish species of the Procambarus subgenus Scapulicambarus (P. clarkii, P. howellae, P. paeninsulanus, P. okaloosae, and P. troglodytes) were compared electrophoretically at 21 loci to evaluate their phylogenetic relationship. Cambarus striatus and P. acutus were also included for outgroup comparisons. Results were summarized in a distance Wagner tree. Two clades were found within Scapulicambarus, one containing P. clarkii and P. troglodytes, and the other containing P. howellae, P. paeninsulanus, and P. okaloosae. The placement of P. okaloosae was contrary to expectations based on morphology, but otherwise the Wagner network was in agreement with previously existing notions of the phylogeny of Scapulicambarus. The mean Rogers genetic distance between Scapulicambarus species pairs was 0.097, indicating a relatively recent origin of the subgenus.
