Justification: Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. |

| Range Description: | This species occurs in lowland and premontane zones from Costa Rica and Panama to montane Colombia and northwestern Ecuador. In Costa Rica it is found primarily on the lower Atlantic slopes of the cordilleras, and in the lowlands and on the slopes of the southwestern region. In Colombia, it occurs in the Pacific lowlands, on the lower western slopes of the Cordillera Occidental, and around the northern edge of the Cordillera Occidental and Cordillera Central to the Middle Magdalena Valley. It occurs from near sea level up to 1,600m asl. |

| Habitat and Ecology: | It is a secretive, nocturnal leaf-litter species of humid lowland, montane forest, including secondary forest and areas close to these forests. Adults are generally found under fallen logs and other surface debris. Breeding takes place in swamps and shallow water-filled depressions on the forest floor. |
| Systems: | Terrestrial; Freshwater |
| Major Threat(s): | The major threats are likely to be deforestation for agricultural development, plantations, illegal crops, logging, and human settlement, and pollution resulting from the spraying of illegal crops. |
| Conservation Actions: | It occurs in many protected areas. |
