          Abstract

          The study of anuran advertisement calls is very significant for it is an important premating premating mechanism. Herein we redescribe the advertisement call of Aplastodiscus arildae from an area near type-locality and describe the advertisement call of A. weygoldti comparing them to previously described advertisement calls of species of the genus Aplastodiscus. Both advertisement calls are simple, non-modulated calls, very similar to each other, but significantly different in what matters to call duration. We describe the first distress call registered for the genus, the distress call of A. arildae, that does not have rigid form and was only recorded for one individual. Some general notes of the genus Aplastodiscus are given.

          Translated abstract

          As vocalizações de anuros são um importante mecanismo de isolamento pré-zigótico, e por isso seu estudo deve ser incentivado. Neste artigo re-descrevemos o canto de anúncio de Aplastodiscus arildae, de uma área mais próxima da localidade tipo e descrevemos o canto de anúncio de A. weygoldti comparando-os a cantos previamente descritos de outras espécies do gênero. Ambas as espécies apresentam os cantos de anúncio simples, não-modulados, muito similares, mas significativamente diferentes no que diz respeito à duração da nota. Descrevemos o primeiro "distress call" registrado para o gênero, o "distress call" de A. arildae, que não possui uma forma rígida e foi emitido apenas por um dos indivíduos coletados. Notas sobre o gênero Aplastodiscus são dadas.
