Dos nuevas especies de ranas (Amphibia: Leptodactylidae) de páramo del Parque Nacional Sierra Nevada, Venezuela

Abstract

Dos nuevas especies de ranas (Amphibia: Leptodactylidae) de paramo del Parque Nacional Sierra Nevada, Venezuela Reportamos el primer registro de Hyalinobatrachium ruedai para Ecuador, extendiendo su distribucion desde Colombia hasta los flancos centrales de la Cordillera Oriental de Ecuador. El analisis del material adicional y de la serie tipo de H. ruedai nos permite discutir su variacion morfologica y de coloracion. Algunas caracteristicas previamente conocidas solo para taxones del Macizo Guayanes (ej. iris bicolor) son reportadas en H. ruedai. Se recomienda no subdividir al grupo H. fleischmanni en subgrupos. Comentamos el estado taxonomico de algunas especies de la region Pacifica de Ecuador, caracterizamos a H. petersi y reconocemos que actualmente bajo los nombres Hyalinobatrachium fleischmanni y H. valerioi hay al menos tres especies aun no descritas. Palabras clave : Amphibia, Anura, Centrolenidae, Hyalinobatrachium ruedai, distribucion, variacion, taxonomia. Abstract: Two new species of frogs (Amphibia: Leptodactylidae) from paramo in Sierra Nevada National Park, Venezuela Two new species of frogs of the genus Eleutherodactylus (Amphibia: Leptodactylidae) are described from Sierra Nevada National Park, in the Cordillera de Merida, Venezuelan Andes. Both are species inhabiting paramo environments. One of them comes from the Mucubaji region and can be easily distinguished from its congeners in the area by possessing a skin with a wet look, blackish coloration, as well as by its small size and absence of expanded disks on digits. The other species comes from the area of the Merida cable car and only could be confused with Eleutherodactylus colostichos from which it could be distinguished by its large size, unconspicuous dorsolateral bands, first finger shorter. In both cases it is presented a description of the than second and large shanks. In both cases a description of the holotype of the species is presented, accompanied by a definition and diagnosis, data on natural history, distribution and ethymology. Key words: Amphibia, Leptodactylidae, Eleutherodactylus, taxonomy, Cordillera de Merida, Andes, Venezuela.
