|Types||Holotype: MVZ 263880, an adult female, Museum of Vertebrate Zoology (Fig. 2), collected 16 January 2008, by Sean M. Rovito and Theodore J. Papenfuss.|
|Diagnosis||Diagnosis. Sibon merendonensis is a member of the S. annulatus group as defined by Savage (2002) in having the penultimate supralabial separated from the eye by the lower postocular (Fig. 3). It differs from all other mem- bers of the S. annulatus group in having a scale row formula of 15–17–17 rather than 13–13–13 in S. anthracops, 15–17–15 in S. perissostichon, and 15–15–15 in all other species in the group. Larger (TOL=687 mm) than all other members of the S. annulatus group [female TOL range of 366 mm–557 mm (McCranie 2007)], except S. dimidiatus (maximum female TOL of ca. 800 mm) and S. perissisticon (TOL=668 mm). Dorsal scale rows retain normal orientation vs. changing orientation from sides of body to dorsal midline in S. perissostichon. Table 1 (mod- ified from McCranie 2007) compares S. merendonensis with all other members of the S. annulatus group [ROVITO et al. 2012].|
|Etymology||The specific epithet makes reference to the Sierra del Merendón, the mountain range containing the type locality.|
