Abstract
One of the most extreme adaptations to terrestriality in anurans is direct development, where eggs from terrestrial clutches entirely circumvent an aquatic tadpole stage and directly develop into small froglets. We here report the first case of egg-burying behaviour in a neotropical direct-developing frog with subsequent short-term maternal care. An amplectant pair of Pristimantis chocoensis was found at the Reserva Canandé in Esmeraldas, Ecuador, and we recorded oviposition and the later rotation and active burying of the clutch by the female. Both parents remained close to the nest area the following day. This rare observation sheds light on the complex but often cryptic reproductive behaviours of terrestrial amphibians and suggests that the evolution of direct development has selected for highly specialized forms of parental care.
