A new species of the deep-sea dragonfish genus Eustomias is described from 14 specimens from the western North Atlantic. This species belongs to the subgenus Neostomias, which is defined principally by the presence of a single pectoral ray, plus one small rudimentary ray. It is unique among members of the subgenus in having a combination of characters that includes a short mental barbel, multiple proximal bulbs on the barbel main stem, and a unique terminal bulb morphology. Analysis of similar species warrants resurrection of Eustomias monodactylus, previously placed in synonymy with Eustomias filifer. A revised key to the species of the subgenus Neostomias is provided.
