Type locality: Colombia, Departamento Santander, Municipio Piedecuesta, Vereda Tres Esquinas, approximately 6°59’22’’N, 73°3’13’’W.

TypesHolotype: UIS R 478, adult male, 23 Feb. 1999, Rances Caicedo. 
DiagnosisDiagnosis.—Stenocercus santander differs from all other species of Stenocercus (except S. erythrogaster, S. huancabambae, and S. limitaris) in having keeled ventrals, strongly keeled and imbricate head scales, distinct parietals, interparietal, and post- parietals, strongly laterally compressed tail and prominent vertebral crest in adult males, distinct posthumeral mite pocket, nostrils medial to canthus, and postxiphisternal inscriptional ribs in contact medially (Torres-Carvajal, 2004). It differs from S. erythrogaster (character states in parentheses) in havi ng a more prominent, serrate vertebral crest in adult males that extends from posterior border of head onto less than half the length of tail (vertebral crest low, serrate only anteriorly), a distinct postfemoral mite pocket (postfemoral mite pocket absent), and in lacking a dark stripe extending anterodorsally from subocular region across eyelids (dark stripe present ). The new s peci es di f f ers f rom S. huancabambae (character states in parentheses) in having two canthals (one canthal) and in lacking dorsally projected angulate temporals
(two projected angulate temporals). Stenocercus santander is different from S. limitaris in color patterns (e.g., males of S. santander lack a distinct black mark on the ventral surface of neck, which is characteristic of S. limitaris); moreover, males of S. santander have a more prominent vertebral crest than males of S. limitaris.
