Taxonomic Relationships

Coleonyx variegatus abbotti is a close relative of C. v. variegatus. Its initial description was based primarily on coloration, pattern, and scalation (Klauber 1945). Sequence data from seven nuclear DNA markers confirm the distinctiveness of C. v. abbotti but also restrict the known range (see the “Distribution” section). The two taxa are not genetically isolated but have an abrupt genetic and morphological contact zone in Baja California and possibly also in Southern California (D. Leavitt, unpublished data).
