Abstract

Four new species of Liolaemus are described from the Patagonia region of southern Argentina. One species was collected in southern Neuquén Province and the other three are from Río Negro Province. Each of the new species has a patch of enlarged scales on the posterior surface of the thighs, indicating their relationship to members of the boulengeri group. Within this group, the four new species are morphologically most similar, and may be most closely related to, Liolaemus boulengeri. A total of 98 external morphological characters, principally squamation, color pattern, and body proportions, were recorded for these new members of the boulengeri group and compared with those for Liolaemus boulengeri. Significant differences between the new species and Liolaemus boulengeri were primarily in color pattern and some aspects of squamation. The new species are distributed over three Patagonian regions with differing geological histories and plant associations. The new species described from central and southwestern Río Negro Province experience substantial differences in daily and seasonal temperature. All four new species eat insects.
