KAPLAN, Moises. Histological examination of the external oral apparatus of the tadpole of Dendropsophus microcephalus (Hylidae, Hylini). Caldasia [online]. 2017, vol.39, n.1, pp.13-18. ISSN 0366-5232.  https://doi.org/10.15446/caldasia.v39n1.64319.

I examined the oral morphology of tadpoles of Dendropsophus microcephalus using histological sections in order to test several conflicting hypotheses. This study shows that there is a well-defined oral disc modified into a rigid tube and hidden beneath a fold of skin. There is one dermal ridge on the upper labium, but tooth rows and papillae are absent. I found that the oral morphology of D. microcephalus is similar to that of two other species of the D. microcephalus group.
