Abstract

Eptatretus aceroi, new species, is described from one specimen captured on the upper continental slope in Colombian Caribbean waters at 705 m depth. The species can be distinguished from all congeners by having five gill apertures, 3/2 multicuspid teeth in the outer and inner tooth rows, respectively, an extremely slender body with the depth at the vertical through the pharyngocutaneous aperture 2.4% of the total length, and by having a total of 174 slime pores, the highest count in the genus. The species is compared with the other western Atlantic five-gilled species of Eptatretus.

Se describe a Eptatretus aceroi a partir de un espécimen capturado en el talud continental superior del Caribe colombiano a 705 m de profundidad. La especie se distingue de todos sus congéneres por poseer cinco aberturas branquiales, un patrón dental de 3/2 dientes multicúspidos en la hilera externa e interna respectivamente, un cuerpo extremadamente delgado, con un profundidad del cuerpo a nivel del ducto faringocutáneo de 2.4% de la talla total, y por tener un conteo total de poros de 174, el mayor conteo en el género. La especie se compara con otras especies de Eptatretus del Atlántico occidental que presentan cinco aberturas branquiales.
