“ Scalation and morphological characteristics for the species of the Liolaemus elongatus-kriegi complex occurring near Liolaemus scorialis sp. n. and Liolaemus zabalai sp. n. distribution. Juvenile specimens examined are excluded. Source of data for not examined species are: Liolaemus antumalguen ( [10] ) , Liolaemus burmeisteri ( [14] ) , Liolaemus choique ( [17] ) , Liolaemus punmahuida ( [13] ) and Liolaemus tregenzai ( [33] ) . (*) [23] . M = males; F = females. ”

“ This population is completely isolated from other populations of Liolaemus buergeri and some specimens exhibit a completely black ventral coloration, a feature absent in other populations of Liolaemus buergeri ( [27] , [25] ) . A more conclusive study in regard to this population should be conducted. Besides, there is diverse evidence supporting the existence of at least three more undescribed species currently assigned to Liolaemus buergeri in Argentina ( [23] , [29] , [9] ) . ”

“ One female has rusty-colored scales dispersed on the flanks, paravertebral fields and groin. In all specimens, the ventral surface of the throat, belly and limbs are whitish with dark marked or inconspicuous dots dispersed; there is a fragmented midventral stripe on the belly of two specimens. Males and females have a yellowish coloration in the posterior portion of the belly and the thighs (faint in some females) . The tail has black rings, marked or diffuse, with a fragmented vertebral stripe in all specimens with complete original tails. Males have orange precloacal pores. ”

“ The suprafemoral scales are rhomboidal to rounded, imbricate, and smooth or slightly keeled. Infrafemoral scales are rounded, smooth, and imbricate. Supra-antebrachials scales are rhomboidal to rounded, imbricate, and slightly keeled or smooth. Infra-antebrachials are rounded to rhomboidal, subimbricate with few interstitial granules, and smooth. The dorsal scales of the tail are rhomboidal, imbricate, keeled and some with mucrons. The ventral scales of the tail vary from rhomboidal to triangular, and are imbricate and smooth. ”

“ Arm length: 24.8–29.4 mm. Tail length: 105–115 mm (in two specimens without autotomized tails) .
The variation of the scalation in Liolaemus zabalai is as follows. Midbody scales: 90–104 (x = 94.3 ± 4.8) . Dorsal scales: 86–96 (x = 89.4 ± 3.2) . Ventral scales 116–122 (x = 119.5 ± 2.1) . Fourth finger lamellae: 19–22 (x = 20.9 ± 1.0) . Fourth toe lamellae: 26–27 (x = 26.8 ± 0.5) . Supralabial scales: 6–7 (x = 6.6, ± 0.5) . Infralabial scales: 4–5 (x = 4.6 ± 0.5) . Interparietal scale pentagonal, hexagonal or heptagonal, bordered by 5–8 scales (x = 7.3 ± 1.1) . Precloacal pores in males: 3–4. ”

“ There is no differentiated auricular scale. Forty-two gulars between auditory meatus. Well developed “Y” shaped lateral neck fold with antehumeral and posthumeral folds developed. Dorsolateral fold slightly developed. Midbody scales 90. Dorsal scales on the vertebral zone are lanceolate to rounded, subimbricate, keeled and without mucrons. Dorsal scales on the paravertebral fields are more rounded, subimbricate, smooth or with less developed keels, without mucrons and there are interstitial granules between them. Dorsal scales are smaller than the ventral scales. Dorsal scales 86. ”

“ Head length (from the posterior border of the auditory meatus to the tip of the snout) 16.4 mm. Head width (distance between the two ear openings) 11.4 mm. Head height (at the level of ear openings) 6.9 mm. Forelimb length 21.1 mm. Hindlimb length 39.7 mm. Foot length 18.9 mm. Rostral scale wider (2.5 mm) than high (1.0 mm) . Two postrostrals. Four internasals. Hexagonal interparietal scale, with a central, small, and whitish spot marking the position of the parietal eye. Interparietal smaller than parietals, surrounded by six scales ”
