Abstract
A new genus and species of deep-sea zoarcid fish, Pyrolycus manusanus, is described on the basis of eight specimens collected from a hydrothermal vent field in the Manus Basin, Papua New Guinea, at depths of 1623–1971 m. This genus is distinguished from other scaleless eelpout genera in the subfamily Lycodinae by the following combination of characters: six suborbital bones; six to seven suborbital pores; flesh gelatinous; gill slit large, extending ventrally beyond pectoral fin base; three postorbital pores; single occipital pore; two to three pelvic fin rays; palatopterygoid series weak; vomer and palatine teeth present; pseudobranch, scales, lateral line absent; pyloric caeca present; 16–17 pectoral fin rays; 22–23 + 56–59 = 78–81 vertebrae.
