A new species of Dysalotus (family Chiasmodontidae) known only from off the Hawaiian archipelago is described here as Dysalotus pouliulii sp. nov. It differs from all other species of Dysalotus in having a greater number of teeth on the premaxilla (151-198 v. 60-138) and dentary (136-199 v. 76-132) and in a shorter upper jaw [51·9-54·9% of head length (L H ) v. 62·4-74·4% L H ] and lower jaw (64·8-67·4% in L H v. 75·3-88·1% in L H ). A key for the species of Dysalotus and an updated distribution map are provided. http://zoobank.org/urn:lsid:zoobank.org:pub:E9B5F1DC-52E0-4F53-9109-2A8E252AE8CE.
