              Three Tylodephys species are known to co-exist in the brain of Galaxias  maculatus: T. argentinus, T. barilochensis and T. crubensis. In order to determine the species present in G. maculatus from lake Gutiérrez, specimens were captured using baited traps every month from April to December 1995. A total of 1526 metacercariae were separated for identification, and multivariate techniques were applied on meristic variables measured on stained mounted metacercariae. Two species were identified through these techniques T. barilochensis and T.  crubensis.
