Description
Summary:The ectoparasitic fauna associated to marine mammals is scarcely known in Chile. This report deals with a sample of Anoplura parasites collected from adult and juvenileOtaria flavescens, the southern sea lion, at the Los Lagos Region, Chile. The Anoplura were taxonomically determined using the existent keys and they were subsequently described. This is the first record ofAntarctophthirus microchirin Chile which, together with what is already known about the geographical distribution and the world evolutionary history of the Otariidae, could represent another evidence of the monophyly of the northern and southern hemisphere Otariidae groups. Los ectoparásitos de los mamíferos marinos en Chile son poco conocidos. Se recolectaron individuos en animales adultos y jóvenes de una lobería reproductiva de lobo marino común (Otaria flavescens)en Isla Metalqui, de la Región de Los Lagos, Chile. Se identifican y describen los especímenes de Anoplura apoyado en claves existentes. Dicha descripción y la comparación con la evolución y distribución de la familiaOtariidaeen el mundo nos permite concluir queAntarctophthirus microchires una especie descrita por primera vez en Chile y podría representar una posible evidencia de un origen monofilético de los grupos de Otariidae en los hemisferios norte y sur.
