N2 - After a preceding revision based on 87 specimens, the systematics of the abyssal giant cuskeel genus Spectrunculus Jordan and Thompson, 1914 has been revisited, based on the examination of 34 additional specimens and new otolith shape data of the holotype of S. grandis. From the latter, a clear distinction in otolith ostium width could be found in specimens from the Atlantic, Southern Indian Ocean, and Southwest Pacific, which were formerly identified as S. grandis. Consequently, the new species, S. stenostio, is described, which has a narrower ostium when related to its length or to sulcus length and differs also in the combination of three body shape characters, three meristic characters, and maximum size from the three other congeners, S. crassus (Atlantic, East Pacific), S. grandis (Pacific), and the previously synonymized S. radcliffei (Pacific, Southern Indian Ocean, Southeast Atlantic). The latter species is here resurrected based on a rather short pre-anal length and additional morphometric as well as meristic and maximum size differences. An identification key for the four species of Spectrunculus is provided.
