Redescription of Liolaemus dorbignyi Koslowsky, 1898 and description of a new species of Liolaemus (Iguania: Liolaemidae)

Liolaemus dorbignyi is re-described, and its type locality restricted to the Sierra de Fiambala, Catamarca Province, Argentina. Also, Liolaemus scrocchii sp. nov., a new species of Liolaemus belonging to the L. montanus series, previously confused with L. dorbignyi, is described. This new species inhabits the phytogeographic region of Puna in Argentina at 3500 m. and is distributed in Jujuy and northwestern Salta provinces. Diagnostic characters include the color pattern, (composed of transverse paravertebral spots, that are band shaped and never reach the lateral region, and never contact the vertebral zone), and the number of scales around midbody. Several populations from different localities were considered L. dorbignyi because of their color pattern and squamation. Even though part of this confusion is clarified in this contribution, some populations still require further study.
