I examined the oral morphology of tadpoles of D. 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.

Examiné la morfología oral de renacuajos de Dendropsophus microcephalus usando cortes histológicos con el objeto de probar varias hipótesis contrapuestas. Encontré que hay un disco oral bien definido y modificado formando un tubo rígido que está oculto debajo de un pliegue de piel. Existe una cresta dérmica en el labio superior pero no hay hileras de dentículos o papilas. Encontré que la morfología oral de D. microcephalus es similar a la de otras dos especies del grupo D. microcephalus.
