|Distribution||Argentina (Catamarca, La Rioja)|
Type locality: 9.2 km East de la plaza central de Pituil,
Ruta Pcial 11, Dpto Famatina.
|Types||Holotype: FML 2659|
|Diagnosis||Diagnosis: Liolaemus koslowskyi differs from all other members ofthe L. darwinii complex, except L. darwinii, L. abaucan and, perhaps L. uspallatensis in having conspicuously enlarged, dark brown or black prescapular and postscapular spots, from L. darwinii in lacking intensely dark pigment within the antehumeral fold, and from L. abaucan and L. uspallatensis in having larger, more strongly keeled dorsal scales and a different dorsal color pattern. (Etheridge 1993: 160).|
Variation. Maximum size, and variation in tail/total length, scale counts and precloacal pore numbers provided in Tables 1-4. Males 41 to 48 mm snout-vent length. ( (Etheridge 1993: 160).
Coloration: Males with standard pattern, modified only by enlargement and darkening of prescapular and postscapular spots; smaller males unknown. Adult males characteristically with pattern as described for holotype: middorsal and dorsolateral light stripes prominent on neck and anterior body, fading to obscurity on posterior body and tail; prescapular and postscapular spots enlarged, very dark and conspicuous; paravertebral spots enlarged and diffuse, oftenjoined medially, when alternate forming a dark zig-zag with diffuse edges between dorsolateral stripes. Sides ofbody usually speckled, but one or more dark, lateral spots posterior to postscapular may be present. Wide, conspicuous, dorsolateral light stripes occasionally present from head to tail. Throat always spotted, but marks may be few and indistinct, or numerous and discrete, at times forming a reticulum; ventral body immaculate or with scattered, indistinct greyish spots; apparently no ontogenetic change in throat and ventral body pattern.
Females with standard pattern retained or reduced and faded, usually at least some indication of dorsolateral stripes and paravertebral spots remaining the stripes often prominent. Some females with postscapular spots somewhat enlarged and darkened. Throat and ventral body with same range ofvariation as males, but tendency for fewer, less distinct markings. Gravid females with orange or reddish-orange pigment on the sides of the head and neck. Populations on sandy flats such as Bajo de Santa Elena (PI. 1.4) and the borders of Salar de Pipanaco, with pale tan ground color; individuals inhabiting rocky areas darker (PI. 1.5). (Etheridge 1993: 160).
|Comment||Member of the darwinii group of Liolaemus.|
|Etymology||Named to honor Julio Koslowsky (1886-1923), in recognition of his contributions to the herpetology of Argentina, and especially the provinces ofLa Rioja and Catamarca (Koslowsky, 1895, 1898), where this species occurs.|
