Redescription of Physalaemus spiniger (Anura: Leptodactylidae) and Description of Two New Reproductive Modes

Abstract

We redescribe Physalaemus spiniger and describe its tadpole and its reproductive modes. This species has the following three alternative reproductive modes: (1) foam nest on pond and feeding tadpoles in pond (the typical mode for the genus Physalaemus); (2) foam nest on humid places on the forest floor near a pond, and feeding tadpoles in pond; (3) foam nest on water accumulated on the axils of terrestrial bromeliads and feeding tadpoles in pond. These last two modes were not included in the reviews of reproductive modes in anurans. The vocalizations of P. spiniger are described and compared with the vocalizations of P. nanus, a sibling species.
