English. A limnological study of the Ponuga River (Province of Veraguas, Republic of Panama) is carried out in order to determine the biological quality through the analysis of invertebrates collected in its waters. Among the group of these organisms were some freshwater sponges, their gemmules and their colonies. The observation of these gemmules under the scanning electron microscope (SEM) allowed the identification of the species Radiospongilla cerebellata (Bowerbank 1863). The first record of the species for Panama is provided, being, in turn, the second for the Neotropics. Physico-chemical analysis of the waters of the Ponuga River is added as a contribution to the knowledge of the species. The successive records of the species in recent years and in different biogeographical areas would indicate that its distribution could be broader.

Se efectúa un estudio limnológico del río Ponuga (Provincia de Veraguas, República de Panamá), con objeto de analizar la calidad biológica basada en los invertebrados recolectados en sus aguas. Entre el conjunto de estos organismos se aislaron gémulas de esponjas de agua dulce y algunas colonias de la misma. Dichas gémulas permitieron identificar a la especie Radiospongilla cerebellata (Bowerbank 1863) mediante observación al microscopio electrónico de barrido (SEM). Se aporta la primera cita de la especie para Panamá, siendo, a su vez, la segunda para el Neotrópico. Se añade análisis físico-químicos de las aguas del río Ponuga como contribución al conocimiento de la especie.
