We describe collections oiHatcheria macraei (Patagonian catfish) from south-central Chile. This represents a significant range extension for this species. These new records have important biogeographic implications as H. macraei is now recorded within Chilean Province, far north of its previous distributional limit in Patagonian Province. We document a new character, the shape of the dorsal fin, which allows quick and easy discrimination between H. macraei and Trichomycterus areolatus in the field or laboratory. This study highlights the need for careful identification for trichomycterid catfishes from southern Chile.RESUMEN Describimos nuevos registros de Hatcheria macraei (bagre Patagónico) en el área sur-central de Chile. Ello representa una ampliación significativa del rango de distribución de esta especie. Estos nuevos registros tienen importantes implicancias biogeográficas, dado que reportamos a H. macraei dentro de la Provincia Chilena, bastante más al norte de su límite distributional previo en Chile, restringido a la Provincia Patagónica. Además, informamos en este trabajo de un nuevo carácter, correspondiente a la forma de la aleta dorsal, el cual permite una rápida y fácil discriminación entre H. macraei y Trichomycterus areolatus, tanto en terreno como en laboratorio. Este estudio alerta sobre la necesidad de identificar cuidadosamente los bagres de la familia Trichomycteridae del sur de Chile.
