| dc.description.abstract | A new species of semifossorial snake assigned to the genus Atractus is described based on a juvenile specimen collected in a tropophilous forest at about 1050 m elevation from Serrania de Parupano, Lara State, Venezuela. This taxon can be clearly distinguished from the rest of its congeners from Venezuela, and those cis-Andean, by possessing a reddish ventral coloration in life, with a midventral row of black dots, defined better towards its anterior third; adjacent to these there are two lateroventral rows of well-defined dots, smaller and rounded; dorsum uniformly reddish brown; one posterior elongated supratemporal scale; 17-17-17 dorsal scales without apical pits; four infralabial scales in contact with chin shields; frontal scale length shorter than distance to the rostral; rostral slightly visible when viewed from above; frontal shield hexagonal; six maxillary teeth. This discovery represents the first record of the genus for the Lara-Falcon mountainous system, northwestern Venezuela. Key Words: Taxonomy, Ophidia, Colubroidea, Serrania de Parupano, Lara State. Resumen Una nueva especie de serpiente semifosorial (Dipsadidae: Atractus wagler, 1928) del sistema montanoso Lara-Falcon, Noroeste de Venezuela Se describe una nueva serpiente semifosorial perteneciente al genero Atractus, con base en un solo ejemplar juvenil coleccionado en un bosque tropofilo a unos 1050 msnm en la Serrania de Parupano, Estado Lara, Venezuela. Este taxon se distingue claramente del resto de sus congeneres de Venezuela y de aquellos cis-Andinos por poseer una coloracion ventral rojiza en vida, la cual tiene una hilera medioventral de puntos negros, mejor definidos hacia su primer tercio; adyacentes a estos tiene dos hileras lateroventrales de puntos bien definidos, mas pequenos y redondeados; dorso pardo rojizo uniforme; una escama supratemporal posterior alargada; 17-17-17 escamas dorsales sin fosetas apicales; cuatro escamas infralabiales en contacto con geneiales; largo de la escama frontal mas corta que la distancia a la rostral; rostral ligeramente visible desde arriba; escudo frontal hexagonal; seis dientes maxilares. Este hallazgo representa el primer registro del genero al nor-occidente de Venezuela, correspondiente al sistema montanoso Lara-Falcon.
