MIJARES-URRUTIA, Abraham; MANZANILLA-PUPPO, Jesús  and  LA MARCA, Enrique. Una nueva especie de Tepuihyla (Anura: Hylidae) del noroeste de Venezuela, con comentarios sobre su biogeografía. Rev. biol. trop [online]. 1999, vol.47, n.4, pp.1099-1110. ISSN 0034-7744.

A new species of treefrog, Tepuihyla celsae (Hylidae), is described based on 11 specimens from cloud-forests (1250 m) of the Sierra de San Luis, state of Falcón, northwestern Venezuela. The new species is distinguished from its congeners by dorsal pattern dark-brown with some few, small and scattered white spots, upper lip immaculate white, dorsum strongly tuberculated in both sexes, dorsal spicules absent, eye-naris distance longer than horizontal length of eye, fingers lacking webbing, axillary membrane absent. This new Tepuihyla extend the known range of the genus more than 500 km northwesterward, and is the first report of the genus outside the Guyanan masif, adding new evidence to support a close biogeographic affinity among the Sierra de San Luís and the Cordillera de la Costa with the highlands of the Guyanan región.
