Abstract

An analysis of karyotypes, allozymes, color pattern, and distribution indicates that the Sceloporus magister complex is composed of three species. Sceloporus zosteromus is endemic to the Baja California peninsula and is composed of what was formerly considered S. rufidorsum, S. monserratensis, and S. zosteromus. The insular endemic of Isla Santa Catalina, S. lineatulus, is given full species status, and S. magister is considered here to be monotypic and to contain the remaining populations. /// El complejo Sceloporus magister está compuesto de tres especies; S. zosteromus de Baja California, S. lineatulus de Isla Santa Catalina en el Golfo de California, y S. magister del suroeste de los Estados Unidos y noroeste de México. Se muestre que todas las subespecies de este complejo son clases patrones y se recomende que ellos no se deben a reconocer en clasificaciones con base en linajes.
