| Diagnosis | Diagnosis—Liolaemus dorbignyi belongs the L. montanus group (Etheridge, 1995), because it has a blade-like process on posterior distal tibia, associated with a greatly hypertrophied M. tibialis anticus (Abdala, et al. 2006). Within this group, the presence of scales of equal size on the posterior face of the femur differen- tiates it from the L. boulengeri group (Abdala, 2007). Among the species that have not a patch of enlarged scales on the posterior face of the femur, L. dorbignyi is a robust and large sized Liolaemus (max SVL 98.3 mm) which distinguishes it from L. andinus Koslowsky, L. audituvelatus Núñez and Yáñez, L. disjunctus Laurent, L. eleodori Cei et al., L. erroneus Núñez and Yáñez, L. etheridgei Laurent, L. fabiani Yáñez and Núñez, L. famatinae Cei, L. fittkaui Laurent, L. griseus Laurent, L. huacahuasicus Laurent, L. insolitus Cei and Péfaur, L. islugensis Ortiz and Marquet, L. molinai Valladares et al., L. montanus Koslowsky, L. multi- color Koslowsky, L. ortizi Laurent, L. pantherinus Pellegrin, L. poconchilensis Valladares, L. poecilochromus Laurent, L. pulcherrimus Laurent, L. reichei Werner, L. rosenmanni Núñez and Navarro, L. ruibali Donoso- Barros, L. signifier Dumerill and Bibrón, and L. vallecurensis Pereyra, (max SVL 50–70 mm). Liolaemus dor- bignyi has flat dorsal scales, imbricate, and slightly keeled, character states that distinguish it from L. andinus, L. audituvelatus, L. erguetae Laurent, L. erroneus Núñez and Yáñez, L. forsteri Laurent, L. insolitus, L. islu- gensis, L. molinai, L. patriciaiturrae Navarro and Núñez, L. poecilochromus, L. robertoi Pincheira-Donoso and Núñez, L. rosenmanni, and L. schmidti Marx (smooth and juxtaposed dorsal scales). It may also be distin- guished from L. aymararum Veloso et al., L. disjunctus, L. etheridgei, L. fittkaui, L. huacahuasicus, L. monta- nus, L. ortizi, L. polystictus Laurent, L. stolzmanni Steindachner, L. thomasi Laurent, and L. williamsi Laurent, which have dorsal scales imbricate but strongly keeled. Liolaemus chlorostictus Laurent, L. jamesi Boulenger, L. orientalis Müller, L. poconchilensis, L. robustus Laurent, L. signifier, and L. stolzmanni, have weakly keeled but juxtaposed dorsal scales, characteristic that distinguishes it from L. dorbignyi. The number of scales around midbody in L. dorbignyi is 48 to 59, fewer than in L. andinus, L. disjunctus, L. duellmani Cei, L. eleodori, L. erguetae, L. foxi Núñez et al., L. islugensis, L. molinai, L. multicolor, L. nigriceps Philippi, L. patriciaiturrae, L. pleopholis Laurent, L. poecilochromus, L. pulcherrimus, L. robertoi, L. rosenmanni, L. ruibali, L. signifer, and L. vallecurensis, which have 64 to 110. Females of L. dorbignyi have precloacal pores, differing from following species in which females lack precloacal pores, L. andinus (Koslowsky, 1895), L. duellmani (Cei, 1986), L. fabiani (Pincheira-Donoso and Núñez, 2005), L. islugensis (Ortiz & Marquet, 1987), L. jamesi (Pincheira-Donoso and Núñez, 2005), L. melanogaster (Lurent, 1998), L. pantherinus ((Pincheira-Donoso and Núñez, 2005), L. puritamensis Núñez and Fox, L. robertoi, L. rosenmanni, L. signifer and L. stolzmanni (Pincheira-Donoso & Núñez, 2005), and L vallecurensis. The presence of precloacal pores in females could be problematic for the diagnosis, because some species are known for few specimens, but we used this character because the new species show a high percentage of females with precloacal pores and in all the samples (from different localities), at least one female exhibit pores. The dorsal color pattern is formed by dark bands transverse to the longitudinal body axis, and which searate the laterals and the ventral color, distin- guishing it from the others species of the L. montanus group [from QUINTEROS et al. 2008]. |
| Comment | Synonymy: Liolaemus dorbignyi has been split up into several species, including L. huayra, L. inti, L. scrocchii and L. vulcanus, hence the range of the original dorbignyi has shrunk significantly (see Nori et al. 2021: Fig. 1 for a map).Liolaemus puritamensis NUNEZ & FOX 1989 has been considered as a synonym of L. dorbignyi (e.g. NUNEZ 1992) but later revalidated. Distribution: Map in Quinteros & Abdala 2011. Not in Chile or Bolivia (Potosí). Records for Chile are L. puritamensis and possibly L. scrocchi. Record for Bolivia are likely to be L. puritamensis or perhaps an undescribed species [pampa_isla, pers. comm., 28 March 2012, citing Quinteros et al. 2008]. |
| Etymology | Named after Alcide Dessalines d'Orbigny (1802-1857), French traveler and naturalist who lived in South America for 8 years (1826-1834). |
