Three new species of small Eleutherodactylus are named from cloud forests of the northern and central Cordillera Central of Colorado. These species occur at altitudes between 2600 and 3370 m in Departamentos Antioquia, Caldas, Quindio, and Tolima. The new species apparently are related to E. leptolophus and E. peraticus that occur at comparable altitudes in the southern portions of the Cordillera Central. A single case of sympatry is known among the five species (between two species in Antioquia). RESUMEN. -Se describe tres especies nuevas y pequefias de Eleutherodactylus de los bosques nublados de la parte norte de la cordillera Central de Colombia. Estas especies se encuentra entre 2600 y 3370 m.s.n.m. en los departamentos de Antioquia, Caldas, Quindio, y Tolima. Aparentemente, las especies nuevas tienen parentescos con E. leptolophus y E. peraticus de la parte austral de la cordillera Central (en altitudes comparables). Hay un caso de simpatria entre las cinco especies (entre las especies de Antioquia). Although as many as five or six species of diminutive (adults <30 mm SVL), high-altitude Eleutherodactylus occur in the paramos and high cloud forests on the Nudo de Pasto in southern Colombia (Lynch, 1981, 1984), only three species have been reported from the much larger and topographically more complex Cordillera Central lying to the north of the Nudo de Pasto. Lynch (1980, 1981) reported E. myersi from the southern part of the Cordillera Central (also western edge of the Nudo de Pasto) and named E. leptolophus and E. peraticus from the paramos de Purace and Las Hermosas, respectively. The apparent scarcity of Eleutherodactylus from the northern Cordillera Central reflected lack of lthough as m ny as f ve or ix species of i inutive (adults <30 mm SVL), high-altitude leutherodactylus occur in the paramos and high material rather than some biogeographic pattern. Herein, I describe three new species, apparently most closely related to E. leptolophus Lynch, from the middle and northern portions of the Cordillera Central. When Lynch (1980) described E. leptolophus nd E. peraticus, he considered them allied to E. myersi. Subsequently, Lynch (1984) included E. myersi, but not E. leptolophus or E. peraticus, in a group of seven species found in cloud forests and paramos of northern Ecuador and southern Colombia. Eleutherodactylus leptolophus, E. peraticus, and the three new species have larger digital disks than does any species of the southern group (see Lynch, 1980:182). At present, these ial rather than some biogeographic pat. erein, I describe three new species, apl ost closely related to E. leptol phus , fro the mid le and northern portions 344 This content downloaded from 157.55.39.17 on Wed, 31 Aug 2016 05:14:48 UTC All use subject to http://about.jstor.org/terms
