Abstract
The family Abyssochrysidae, with the single genus Abyssochrysos, is revised, based on type material and new material from the bathyal and abyssal zones of the Atlantic and Indo-Pacific in tropical or subtropical latitudes. Of the five species recognized, two are described as new: Abyssochrysos brasilianum n. sp., from the continental slope off southeastern Brazil, and A. bicinctum n. sp., from Makassar Strait, Indonesia. Abyssochrysos eburneum (Locard, 1897) is recorded for the first time since its description and A. melanioides Tomlin, 1927 is recorded from the Philippines and Indonesia. All of the species in the family are illustrated.
