CommentGroup: kingii group.

Diagnosis—Liolaemus uptoni differs from other Liolaemus species for its coloration and lepidosis, being close to Liolaemus somuncurae belonging to kingii group. Its lepidosis shows a dorsal pattern of paravertebral lighter scales, notoriously keeled and larger than in L. somuncurae. The black parietal pileus is more accentuated. Ventral melanism is moderate, with a reticulate pattern of spots and pigment blots more expanded and confluent on a medial line, and semicircular black bands over the cloacal region. Hindlimbs are long, reaching the antehumeral region in females but exceeding it in males: a character which does not occur in L. somuncurae.

Habitat: Liolaemus uptoni was found under isolated bushes present on sandy grounds and eroded slopes at Bajada del Buey, and west of Pampa de Sacanana,

Chubut. 
EtymologyNamed after a late friend and collaborator of the authors, Jorge Arturo Upton.
