DistributionArgentina (from CW La Rioja to NE Mendoza, between 2700-3500 m elevation)

Type locality: 58 km west of Jagüe, General Sarmiento Department, La Rioja Province, Argentina. 28°29’24.3” S; 68°49’45.3” W, 3532 m elevation.  
Reproductionviviparous (not imputed, fide Zimin et al. 2022) 
TypesHolotype: FML 16548. adult male 
DiagnosisDiagnosis: Liolaemus parvus belongs to the L. chiliensis group for having meckel’s groove fused and few or no precloacal pores. within this group it belongs to the petrophilus group (sensu morando et al., 2003 and avila et al. 2004), with L. austromendocinus, L. capillitas, L. dicktracyi, L. gununakuna, L. heliodermis, L. petrophilus, L. talampaya and L. umbrifer. Liolaemus parvus differs from all these species in possessing a shorter snout-vent length (max. sVL 65.1 mm vs 81-103 mm) and a different color pattern. These characteristics also differentiate L. parvus from L. thermarum. it also differs from L. capillitas, L. dicktracyi, L. heliodermis, L. talampaya and L. umbrifer in their absence of red coloration in the cloacal region of males and females; from L. capillitas, L. dicktracyi, L. heliodermis, L. talampaya and L. umbrifer for possessing uniform shoulder coloration, with the absence of black or white spots; from L. austromendocinus in possessing fewer midbody scales (60-77 vs 75-97); from L. austromendocinus, L. heliodermis, L. thermarum and L. umbrifer in possessing more keeled dorsal scales than these species. Liolaemus parvus differs from L. buergeri (included in the capillitas group of Lobo, 2005) in having a shorter snout-vent length (max sVL 65.1 mm vs 108.2 mm), fewer midbody scales (60-77 vs 86-113), fewer ventral scales (96-113 vs 116-139), and a different dorsal color pattern. Liolaemus parvus differs from L. elongatus (with which it was previously confused) by a shorter snout-vent length (max SVL 65.1 mm vs 89.0 mm), fewer midbody scales (60-77 vs 74-89), and a different color pattern.
Etymologyfrom Latin “parvus” = small, as this is the smallest species of the elongatus‑petrophilus group.
