CommentLiolaemus chehuachekenk belongs to the fitzingerii group and is easily distinguished from other members of the group by a combination of morphological and genetic characters. The new species is diagnosable in showing the following combination of characters: dorsal pattern with a conspicuous vertebral band, presence of pre- and postscapular spots, prominent neck folds, and analysis of DNA sequence data from 810 base pairs of the cytochrome b gene (∼4% sequence divergence from its sister taxa Liolaemus fitzingerii). 
EtymologyThe specific name chehuachekenk, comes from the name of one of the main subgroups of the Tehuelches aboriginal people that inhabited western Chubut, Rio Negro, and southern Neuque´ n Provinces and were themselves known as Chehuache-Kenk.
