Abstract

Heterophryxus appendiculatus G. O. Sars, 1885 (Dajidae) infests at least four species of euphausiids. Since 1885 it has been reported from only seven locations worldwide. One freeswimming female specimen was discovered in zooplankton samples from the northeast Pacific Ocean and three more from the Caribbean Sea of Mexico. In the context of all previous geographical reports and Zoogeographie distribution patterns of their euphausiid hosts, we suggest that H. appendiculatus has a wide Zoogeographie distribution in the tropical-temperate belt worldwide. Heterophryxus appendiculatus G. O. Sars, 1885 (Dajidae) infesta al menos cuatro especies de eufáusidos. Desde 1885 ha sido detectado únicamente en siete localidades en el mundo. Se descubrió un espécimen hembra sin hospedero en muestras de zooplancton recolectadas en el noreste del Océano Pacífico y otras tres en el Mar Caribe de México. En el contexto de todos los registros previos y los patrones zoogeográficos de distribución de las especies de eufáusidos hospederas sugerimos que H. appendiculatus tiene una amplia distribución zoogeográfica en el cinturón tropical-templado alrededor del mundo.
