ABSTRACT
The validity of the published description of Hyla rufitela is questioned because the origin of the described tadpoles does not correspond to the distribution of this species. The present description, based on tadpoles that were hatched from two egg masses from the Caribbean lowland of Costa Rica, includes tadpoles raised to adult frogs to verify the species. The newly described tadpoles differ from the previously described and illustrated ones not only in color but also by its more slender body shape (body heightbody length, 0.430.47), the more slender tail (% tail length of total length, 69%63%), the more conspicuous spiracle and its position, as well as by the larger oral disk width (oral disk widthbody width, 0.44~0.33). The young tadpoles continually ingest mud as is typical of bottom feeders. Nevertheless, older larvae feed on plant material like rotting mellow leaves of Piper auritum. The tadpoles metamorphosed between 44 and 114 days (x=80.3 days) under the described breeding conditions
RESUMEN
La existencia de dudas sobre la validez de la descripción de las larvas de Hyla rufitela realizada por Duellman en 1970 motivaron una nueva descripción con base en renacuajos criados de dos masas de huevos de H. rufitela de la zona caribeña de Costa Rica. Algunos se criaron hasta la edad adulta para verificar la identidad de la especie. Los renacuajos difieren de la descripción e ilustración original por su color, la esbeltez (proporción entre altura y longitud del cuerpo 0.43 vs. 0.47), la cola más delgada (% longitud de la cola de la longitud total del renacuajo 69% vs. 63%), por la posición y forma conspicua del espiráculo, por el disco oral más ancho (ancho del disco ancho del cuerpo 0.44 vs. ~ 0.33) y por algunos datos alométricos. Las larvas pequeñas permanecen en el fondo alimentándose con materia orgánica del lodo. Los renacuajos mayores se alimentan de material vegetal en descomposición. En cautiverio las renacuajos terminaron su desarrollo en 44-114 días (promedio 80.3 días)
