Abstract
Near the village of Guayacan de Siquirres, Limon province, Costa Rica (N 10°02", W 83°31') the call of a frog revealed a breeding hole about 15 m high in a Guarea tree. An adult was taken from this water-filled cavity along with some tadpoles. The adult tree frog was identified by B. Kubicki as Ecnomiohyla sukia Savage and Kubicki, 2010. Its sex was not determined. Ten tadpoles were extracted from the water-filled tree hole and it appeared they had only a few days of larval development, but the exact age was undeterminable. The conspecificity of the tadpoles found with the adult frog E. sukia was established by rearing them to metamorphic stages and froglets. The following description is based on tadpoles from stages 25, 36-37, and 41 (Gosner 1960).
