THE LEPOCREADIIDAE (DIGENEA) OF FISHES FROM THE NORTHEAST ATLANTIC - A REVIEW OF THE GENUS LEPIDAPEDON STAFFORD, 1904

The genus Lepidapedon is subdivided into several species groups and su bgroups of species based on the vitelline distribution and the length of the excretory vesicle. The species in each of the subgroups are lis ted and keys to the species in most subgroups are given. The following north-eastern Atlantic species are described or redescribed: Lepidape don rachion from Melanogrammus aeglefinus, Gadus morhua, Aspitrigla cu culus, Merlangius merlangus and Pollachius pollachius; L. cambrensis f rom Enchelyopus cimbrius; L. sommervillae n. sp, from Trachyrincus sca brus, T. murrayi and Coryphaenoides guentheri; L. elongatum from Gadus morhua; L. gaevskayae from Coryphaenoides (Nematonurus) armatus; L, d iscoveryi n. sp. from Coryphaenoides (Nematonurus) armatus; L. arlenae n. sp. from Trachyrincus scabrus and T. murrayi; L. mariannae n. sp. from Gaidropsarus argentatus; Lepidapedon spp. innom (Elongatum-group) from Coryphaenoides guentheri and Coryphaenoides (Chalinura) leptolep is; L. desclersae n. sp, from Lepidion eques, L. beveridgei from Coryp haenoides (Nematonurus) armatus and C. (Chalinura) mediterraneus; and L. zubchenkoi from Coryphaenoides (Chalinura) leptolepis and C. (C.) p rofundicolus. The phylogeny, host-specificity and zoogeography of the genus are briefly discussed.
