Abstract:

A new genus and species of deep-sea fish, Apagesoma edentatum, (family Ophidiidae), is described from deep waters off the Bahamas. It can be distinguished from other ophidiid genera by the following characters: an enlarged and swollen anterior nostril; eyes placed anteriorly on the head; moderate-sized, unsculptured, hemispheric-shaped sagitta; absence of a basibranchial tooth patch; absence of an opercular spine; large sub-terminal mouth, with non-protrusible jaws. Typhlonus delosommatus Hureau et al., 1979 is placed in Apagesoma based on similarities in otoliths, non-protrusibility of jaws, swollen anterior nostrils and absence of a basi branchial tooth patch. Typhlonus contains only the type species, T. nasus Gunther, 1878, which differs from Apagesoma in possessing a much larger and highly sculptured otolith, highly protrusible jaws and presence of a basibranchial tooth patch.
