| Diagnosis | Diagnosis. Differs from s. albostrigatus in not having longitudinal rows of black-tipped dorsal scales and in the females having a higher femoral pore count. It differs from s. schreibersit in having a lateral white stripe that passes through the lower half of the ear and along the side of the body. Description. Similar in scalation to s. schreibersü except for the following: dorsal scales definitely hexagonal; lateral scales equal in size to the dorsals or slightly reduced; in a few specimens the laterals are half the length of the dorsals. Nuchals more regular than in S. schreibersi, forming true nuchal plates, but never so large as in quadrilineatus. Females have from 2/2-3/3 femoral pores while the males have 3/3-5/5. Scale counts. Midbody, 24-29; transverse dorsal rows, 29-35; trans verse ventral rows, 18-22; gulars, 7-8. Color. All of the 44 specimens examined were distinguished by having a white stripe originating below each eye, passing through the lower half of the ear, and above the forelimb. In a few specimens the stripe was not evident on the side of the body, while in some it con tinued along the side of the tail. This lateral stripe is bordered su periorly along all of its length by a dark-brown band. The dorsal surface of the body is of a lighter brown. In about 80 per cent of the specimens a dark vertebral stripe is present. This dark stripe may originate on the nuchal region and extend the entire length of the dorsum and onto the tail. Usually, however, this stripe is broken into an anterior nuchal stripe and a posterior sacral stripe, or the anterior stripe may be lost and only the sacral stripe remain. A few of the specimens show evidence of the dorsolateral white stripe typical of s. schreibersii. An irregular dark stripe extends from each upper labial to the neighboring lower labial. The mental region is cream-colored and spotless except for some of the scales bordering the posterior lower labials. The gulars are spotless or with a few dark flecks. The ventrals are likewise spotless; however, some of the posteriormost scales may have dark flecks. On well preserved specimens the abdomen is pink. In all the specimens the subcaudals are flecked with black. (Ruibal 1952) |
