DiagnosisDIAGNOSIS (genus and species): Ctenoblepharys adspersa is a lizard of the family Tropiduridae, subfamily Liolaeminae (Frost and Etheridge, 1989) which differs from other members of the subfamily (i.e., Phymaturus and Liolaemus) in having a wider skull, larger orbits, wider temporal fenestrae, prefrontals wider than long, lacrimal foramen large, a wide maxillary process of the palatines, a short ectopterygoid, the maxillary process of the ectopterygoid truncate, the retroarticular process of the mandible much shorter than the angular process, the parapophyses of the atlas flat and oriented posterolaterally, and the neural arches of the body vertebrae very wide. It further differs from Liolaemus in having the lateral borders of the orbitonasal fenestra formed by the prefrontals rather than the frontals, the supratemporal exposed on the lateral surface of the supratemporal process of the parietal, a shorter dentary, a longer angular, and no posterior coracoid fenestra. It further differs from Phymaturus in having tricuspid marginal teeth with tapered crowns and small secondary cusps rather than expanded crowns with large secondary cusps, three rather than four sternal ribs, and a slender body with a long, slender tail rather than a depressed body with a short, spinose tail (Etheridge 1995).
