Pacific lowlands from northern Ecuador and eastern Colombia to eastern Panama (Morrone, 2001). This region is characterized by having one of the highest levels of rainfall in the world, ranging between 73013.670 mm/year (Poveda et al., 2004). This high rainfall has been related with a high productivity (rate of conversion of resources to biomass per unit area per unit time), which in turn is considered one of the possible causes of the high biodiversity found in this region (Waide et al., 1999). Chocoan region is considered to be one of the most diverse in the world; however, it is poorly explored in Colombia. The current knowledge of the diversity of the Chocoan region in Colombia is based on a limited number of sample localities given the vastness of this area (Lynch, 1999; Lynch and Suarez-Mayorga, 2004). This region is facing environmental degradation caused largely by deforestation and the emergence of activities related to illegal mining (Rangel-Ch, 2004). Considering the lack of studies in Chocoan region in Colombia and its problematic environmental condition, it becomes necessary to increase the sampling effort in this area, to expand the current knowledge of its species diversity. In this context, we present two new records of rare species of craugastorid frogs for the Pacific lowlands of Colombia (department of Valle del Cauca) previously known only from Ecuador. Collections were made in the Hydroelectric Central Alto Anchicaya, Valle del Cauca, Colombia ( 3.577852 N, -76.880651 W, 600-670 m), March 19-21, 2014. Specimens were euthanized with 20% Herpetology Notes, volume 8: 27-30 (2015) (published online on 10 March 2015)
