Observations on the courtship behavior and nesting in Phyllomedusa venusta (Anura: Phyllomedusidae) from a seasonally dry forest in Colombia. I investigated the reproductive behavior of the poorly known leaf frog Courtship, amplexus, and nesting were observed during the rainy season in an ephemeral pool surrounded by forest. Based on the behavior of a single, amplectant pair, it seems likely that physical stimulation may play a role in courtship in this leaf frog that shows little vocalization. A second amplectant pair formed a nest, with leaves surrounding the clutch in a funnel. Both ends of the nest were plugged with empty jelly egg capsules, which also were dispersed throughout the egg mass. A separate spawn was collected, containing 390 viable eggs. By wrapping eggs in leaves, and depositing water in empty egg capsules in the egg mass and jelly plugs, the frogs doubtless protect developing embryos from desiccation, an important adaptation for leaf-nesting among phyllomedusids.Keywords: amplexus, Caribe, clutch size, reproductive behavior, tree frog.

Phyllomedusa venustaEu investiguei o comportamento reprodutivo da perereca pouco conhecida A corte, o amplexo desempenhar um papel na corte desse anuro que vocaliza pouco. Um segundo casal em amplexo construiu um ninho na forma de funil com folhas envolvendo a desova. Ambas as extremidades do toda a massa de ovos. Foi coletada uma desova separada contendo 390 ovos viáveis. Por enrolar os ovos em folhas e depositar água em cápsulas vazias na massa de ovos e nos tampões gelatinosos, esses anuros sem dúvida protegem os embriões em desenvolvimento contra o dessecamento, uma Palavras-chave: amplexo, Caribe, comportamento reprodutivo, perereca, tamanho da desova.
