Centrocestusformosanus (Digenea:Heterophyidae) is reported for the first time in Colombia, parasitizing snails and fish from the lake of the Joaquín Antonio Uribe botanical garden, Medellín City. Rediae and cercariae were obtained from MAD morphs of the snail Melanoides tuberculata. Metacercariae were found encysted on gills of fish of the families Cichlidae and Poeciliidae while adults were recovered from experimentally infected chicks. Prevalence in adult snails was 74%. Parasitized snails were found to be sterile.

Keywords : Centrocestus; Cichlidae; Colombia; Digenea; Melanoides tuberculata; Poeciliidae.
