HOFFMANN, Heinz. The Tadpoles of Hyla rufitela (Anura: Hylidae). Rev. biol. trop [online]. 2005, vol.53, n.3-4, pp.561-568. ISSN 0034-7744.

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 height:body length, 0.43:0.47), 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 width:body 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. Rev. Biol. Trop. 53(3-4): 561-568. Epub 2005 Oct 3.
