|Diagnosis||Diagnosis. Liolaemus sitesi is a member of the rothi complex, that includes L. hermannunezi, L. loboi, L. sagei, L. rothi, and L. tromen and several other potential species that require further study (Avila et al. 2006; Morando et al. 2004; Olave unpublished data). Liolaemus sitesi can be easily distinguished from all other members of its clade by its black/dark brown background body coloration with small bright yellow, green or white spots distributed along its dorsal and lateral trunk areas; in full sun males take on a yellow-green iridescent coloration on neck, body, limbs and tail; colors not observed in any other species of the group. Liolaemus sitesi differs from L. rothi, L. sagei and L. tromen by its marked sexual dichromatism. Liolaemus sitesi is smaller than L. rothi (maximum SVL: 79.8 vs. 97.00 mm), has more scales around midbody (72.0 ± 2.9 vs. 64.7 ± 4.27) and more supralabial scales (8.0 ± 0.9 vs. 5.49 ± 0.56). Liolaemus sitesi lacks of the conspicuous yellow spots irregularly distributed along the body of L. rothi. Liolaemus sitesi is larger than L. hermannunezi (maximum SVL: 79.8 vs. 71.4 mm), has more dorsal (82.0 ± 2.5 vs. 71.8 ± 1.1), ventral (101.4 ± 4.2 vs. 87.3 ± 1.0), and supralabial scales (8.0 ± 0.9 vs. 7.1 ± 0.7). Liolaemus sitesi is smaller than L. sagei (maximum SVL: 79.8 vs. 88.00 mm), has fewer scales around midbody (72.0 ± 2.9 vs. 90.3 ± 4.68), fewer dorsal scales (82.0 ± 2.5 vs. 101.2 ± 6.59), more supralabials (8.0 ± 0.9 vs. 5.25 ± 0.60), and fewer infralabial scales (5.6 ± 0.4 vs. 6.22 ± 0.42). Liolaemus sitesi is larger than L. loboi (maximum SVL: 79.8 vs. 72.7 mm), has more scales around midbody (72.0 ± 2.9 vs. 63.7), more dorsal scales (82.0 ± 2.5 vs. 67.1), and fewer infralabials (5.6 ± 0.4 vs. 6.4). Liolaemus sitesi differs from L. tromen by having a slender body, a higher number of scales around midbody (72.0 ± 2.9 vs. 65.8 ± 2.2), more dorsal (82.0 ± 2.5 vs. 72.2 ± 3.1) and supralabial scales (8.0 ± 0.9 vs. 7.0 ± 0.6), and a coloration pattern without suprascapular marks or series of subsquare paravertebral spots fused forming transversal bands.|
|Etymology||The specific name is to honor our friend and colleague Jack Walter Sites, Jr. from Brigham Young University, Provo, Utah, USA, who strongly supported and collaborated with us on studies of Patagonian herpetofauna for the last 12 years. Dr. Sites is a herpetologist and evolutionary biologist and devoted the last 30+ years to collaborate with herpetologists from many Central and South American countries, including Argentina, Bolivia, Brazil, Colombia, Chile, Mexico, Peru, Uruguay and Venezuela.|
