Abstract

Cnemidophorus inornatus paululus ssp. nov. from southeastern Durango, México, and adjacent northern Zacatecas, México, differs from all other members of the species in having a high number of femoral pores. In addition, paululus may be distinguished from the nominal form by the dark background between the medial light stripes (light gray in inornatus); paululus possesses eight or nine dorsal light stripes, while the two northern subspecies heptagrammus and arizonae possess six or seven. A series of specimens from several localities in southern Coahuila, México, apparently represent intergrade populations between paululus, inornatus, and heptagrammus.
