[Taxonomic review of species of the Epinephelinae and Serraninae (Pisces: Serranidae) subfamilies of Chile]. / Revisión taxonómica de especies de las subfamilias Epinephelinae y Serraninae (Pisces: Serranidae) de Chile.

A revision of epinepheline (Epinephelinae) and serranine (Serraninae) fishes from the Eastern Chilean South Pacific is presented, based on collections housed in Chile, Peru and the USA. Four species are recognized: Pseudogramma australis pasquensis; Diplectrum conceptione; Paralabrax humeralis and Serranus huacarii. According to literature Paralabrax semifasciatus, Serranus semifasciatus and Prionodes huascarii are relegated to the synonymy of Paralabrax humeralis and Serranus huascarii respectively. Keys for the identification of genera and species are presented, and for each species we provide a diagnosis, remarks on colors, distribution, number of species in each genus and illustration. The keys use easily observed characters for differentiating the four species of the Eastern South Pacific epinepheline and serranine fishes of Chile.

Acanthocolpid metacercariae in the sea bass from Alejandro Selkirk Island, Chile.

Morphological characteristics of a metacercaria from muscle of 15 sea bass Caprodon longimanus (Serranidae) collected near Alejandro Selkirk Island (Chile) in the south-eastern Pacific Ocean indicate that it belongs to the genus Manteria (Acanthocolpidae). All metacercarie were encapsulated with connective tissue. The prevalence of infection was 100%, with 64% of metacercariae were located between dorsal pterygiophores and dorsal fin base. Mean intensities of metacercariae did not differ significantly with respect to sex of the fish. There was no significant correlation with intensities of infection and condition in the host.
