Fel- trin collectors, 16 th January 2008. 
DiagnosisDiagnosis: Liolaemus caparensis sp. nov. is a member of the magellanicus group, in the L. lineomaculatus section, based on molecular evidence (Figure 1). Liolaemus caparensis sp. nov. differs from L. magellanicus in the following traits: shorter tibia-fibula length (6.19-8.62, X = 7.24 vs. 6.91-10.76, X = 9.09; p < 0.0001), shorter radius-ulna length (5.24-5.66, X = 5.24 vs. 5.22-6.88, X = 5.98; p = 0.0017), larger number of midbody scales (39- 55, X = 43.82 vs. 34-48, X = 40.44; p = 0.0282), larger number of dorsal scales (39-47, X = 41.45 vs. 34-45, X = 37.5; p = 0.0003), more ventral scales (64-73, X = 68.36 vs. 49-77, X = 59.17; p < 0.0001), more infradigital lamel- lae of the third finger (14-18, X = 15 vs. 11-15, X = 13.33; p = 0.0006), and more infradigital lamellae of the fourth toe (18-23, X = 20.3 vs. 15-20, X = 18.24; p = 0.0011) (for details see Tables 1 to 4). Liolaemus caparensis sp. nov. has smaller dorsal blotches on the hindlimbs and a more defined vertebral line in comparison with L. magellanicus (Figure 5), as well as fewer precloacal pores than L. magellanicus (3-4 vs. 3-5). Dorsal scales of Liolaemus capar- ensis sp. nov. have a shorter mucron than those of L. magellanicus. The dorsal surface of limb scales is more cari- nated and less mucronated in L. caparensis sp. nov. than in L. magellanicus (Figure 5) [from BREITMAN et al. 2011]. 
CommentGroup: magellanicus group.

Abundance: only known from its original description (Meiri et al. 2017). 
EtymologyThe specific epithet of this species “caparensis” refers to the name “Capar” given to the actual Viedma lake by the Aónikenk aborigines that inhabited this area. The Campo Las Piedras plateau is located on the northwestern edge of Viedma Lake.
