Brachygalaxias bullocki (Regan, 1908) is a fish species endemic to Chile and its distribution is restricted from Concepción to Chiloé Island. A survey conducted during January 2007 involving 26 fish from the Maullín River in Southern Chile, shows that infracommunities richness ranged from 0 to 5 with a mean species richness of 2.3 (SD = 1.3). Nine species of parasites were recorded, and 8 constitute new records of parasites for B. bullocki: Ichthyophthirius sp., Trichodina sp., Epistylididae, Myxobolus sp., Myxidium sp., Tylodelphys sp., Stephanoprora uruguayense, and Diplodon chilensis
