Abstract
Five new species and anew subspecies from deep-sea fishes (800 to 2,860 m) off Oregon are placed in the genus Lepidapedon: L. antimorae from Antimora rostrata; L. filiformis from Chalinura filifera L. cascadensis, L. yaquina, and L. oregonensis from C. filifera and C. serrula;and L. luteum abyssensis from C. filifera, C. serrula, Hemimacrurus acrolepis, and NematonurusTongifilis. All new species have excretory bladders which reach only to the posterior edge of the hind testis and a key to the short-bladdered members of the species is presented. Lepidapedon elongatum reported from a variety of hosts and locations may be a composite of several species and should be restudied.
