We report a geographic range extension for Atractus gigas (colubridae) based on a live specimen found in primary Andean cloud-forest (Bosque Protector Santa Lucía, Pichincha, Ecuador). The specimen represents only the second known record of this species, and the sole live record, discovered 48 km northeast of the type location, and 407 m higher; at an altitude of 2307 m.a.s.l. The specimen agrees with the holotypic head scutellation, with the exception of lacking the azygous frontonasal scale reported in the holotype. We suggest that the holotypic head scalation is aberrant and that the specimen documented here exhibits the typical condition in this species.
