|Diagnosis: Crotaphytus dickersonae can be distinguished from Crotaphytus bicinctores, C. grismeri, C. insularis, and C. vestigium by the presence of black oral melanin, a blue or turquoise dorsal coloration, and the absence of enlarged postanal scales in males. It may be distinguished from C. reticulatus, C. collaris, and C. nebrius by the presence in adult males of a strongly laterally compressed tail with a white or pale stripe extending vertebrally and enlarged dark brown or black inguinal patches extending between one-half and one-third of the distance between the hindlimb and forelimb insertions. It may be further distinguished from C. reticulatus and C. anriquus by the presence of a dorsal pattern of white spots on a blue or turquoise field rather than white reticulations on a gold, tan, or brown field. It may be further distinguished from C. collaris by the presence of dark brown or black pigmentation in the gular fold (= ventrally complete anterior collar)and the absence of enlarged postanal scales in males. It may be further distinguished from C. nebrius by the presence of a blue or turquoise dorsal coloration rather than tan and the absence of enlarged postanal scales in males (McGuire 1996: 80).
|Named after Mary Cynthia Dickerson (1866-1923), former curator of Ichthyology and Herpetology at the American Museum ofNatural History (1909-1921).
