DistributionArgentina (San Juan, La Rioja)

Type locality: 51.3 km South of Villa Unión, Ruta Pcial, 26, Dpto Gral. Lavalle.  
TypesHolotype: FML 2667 
DiagnosisDiagnosis: Adult males of Liolaemus olongasta differ from all other specIes in the L. darwinii complex, except L. laurenti and L. darwinii in having intensly dark pigment within the antehumeral fold. From L. darwinii, L. koslowskyii, and L. abaucan, it differs in lacking dark, conspicuously enlarged prescapular and postscapular spots. From L. laurenti (and from all other members, it differs in having a bold pattern of two dark bars separated by whIte pigment, extending out from the antehumeral fold onto the anterior surface of the forelimb (Etheridge 1993: 168).

Variation. Maximum size, and variation in tail/total length, scale counts and precloacal pore numbers provided in Tables 1-4 in Etheridge 1993.

Coloration: Few adult males with dorsal pattern broken up into irregular dark and light spots, but most similar to holotype, with conspicuous dorsal pattern of stripes and spots not much modified from neonatal standard pattern. Stripes remain, as ground color, or with lighter scales on neck and anterior body. Lateral spots on neck and body sometimes elongate, may be contiguous, forming dark, irregular stripe. Intense black pigment in antehumeral fold, continuous with bold bars separated by white pigment on anterior surface of forelimbs, always present. Sides of head boldly marked. Throat with bold, dark brown spots or streaks, or a broken reticulum; ventral body immaculate or, more often, with bold dark spots and streaks. Anterior surface ofthigh with bold light and dark markings.
Adult female dorsal pattern usually reduced, the paravertebral spots small or absent, the stripes obscure. Lateral spots conspicuous, usually elongate, forming a dark, irregular stripe, bordered below by conspicuous ventrolateral light stripe. Throat with isolated, dusky spots; ventral body immaculate or with scattered spots. Usually the dark antehumeral-forelimb pattern of males represented by some trace (Etheridge 1993: 169). 
CommentMember of the darwinii group of Liolaemus. 
EtymologyNamed to honor the Olongasta tribe, an indigenous people who used to lIve along the border of San Juan and La Rioja provinces where this species occurs today.
