Two New Subspecies of the Liolaemus fitzingeri Complex from Argentina

Abstract

<i>Liolaemus fitzingeri cuyanus</i> n. subsp. from sandy regions north of the Río Colorado (Argentina) and <i>L. fitzingeri xanthoviridis</i> n. subsp. from coastal range of Chubut (Argentina) are described. The former is easily distinguishable from other known forms of the group by a lower number of dorsal scales, lack of ventral melanism and the presence of a distinct black antehumeral band. <i>L. fitzingeri xanthoviridis</i> is distinguishable from its nearest relative <i>L. fitzingeri canqueli</i> by shorter limbs, more distinctly keeled dorsal scales, anterior margin of ear with smaller non-proyecting scales, and different color pattern.
