description A new species, Coniophanes longinquus, is described from the Río Zaña Valley on the western slope of the Andes in northwestern Peru. It is the southernmost species of the genus, and the only one for which definite Peruvian localities are known. It differs from all congeners in having a unique pattern of paired dorsal blotches on the anterior part of the body, and is unusual in having only 17 dorsal scale rows at midbody. The new species appears to be closely related to Coniophanes dromiciformis of southern Ecuador and C. joanae of eastern Panama on the basis of shared details of color pattern and hemipenial structure. The occurrence of Coniophanes dromiciformis in Peru, based on two specimens from the James Orton collection, is questionable. /// Se describe una nueva especie, Coniophanes longinquus, del valle del Río Zaña, que se ubica en la vertiente oeste de los Andes al noroeste del Perú. Es la especie mas al sur del género, y la única para la cual se conocen localidades Peruanas definitivas. Difiere de todos sus congéneres por el patrón de manchas dorsales pareadas en la parte anterior del cuerpo, y es inusual al tener sólo 17 filas de escamas en la parte media. En base a detalles del patrón de coloración y estructura del hemipene, la nueva especie se considera cercanamente relacionada a Coniophanes dromiciformis del sur de Ecuador y a C. joanae del este de Panamá. La ocurrencia de Coniophanes dromiciformis en Perú, basada en dos especímenes de la colección de James Orton, se considera cuestionable.
