Ilyphagus Chamberlin, 1919 is an abyssal flabelligerid annelid genus that includes 4 species; a new species from the Eastern Pacific is herein described: I. gebruki n. sp. This new species is diagnosed as having a cigar-shaped body, more than 5 times longer than wide, with long body papillae, branchial plate with 8 branchial filaments, notochaetae with articles progressively longer, and neurochaetae smooth. The species ranges from off the Aleutian Islands to the Peru-Chile Trench and was sampled in sediments distributed between 5,047 and 7,000 m depth.]]></p></abstract>

La diagnosis de esta especie nueva es que tiene el cuerpo en forma de puro, más de 5 veces más largo que ancho, con papilas corporales largas, placa branquial con 8 filamentos, notosetas con artículos progresivamente más largos, y neurosetas lisas. La distribución de la especie incluye desde la región de las Aleutianas hasta la fosa Perú-Chile y fue recolectada en sedimentos entre 5,047 y 7,000 m de profundidad.]]></p></abstract>
