| Diagnosis | Diagnosis (n=12): Related to Xenosaurus grandis but with the following differences: supraocular scales smaller, never forming a continuous series of three or four, that are much wider than long; tail a little shorter and slenderer with 2-4 scales fewer in a whorl about tail near base; arm above nearly uniformly covered with large rounded scales, somewhat conical on dorsal surface, rather than with the tubercles spaced with the distance between nearly equal to diameter of the base of the tuberele; a pair of light spots beginning between auricular membranes and extending back for a distance less than, or equal to, their width; a broad distinct stripe begins near tympanum that runs up and back, approaching but not meeting its fellow behind posterior level of arm insertion; venter nearly uniform grayish white, instead of cream with numerous quadrangular black spots. (Taylor 1949)
