A review of existing descriptions of Lepeophtheirus from salmonids, based on specimens collected mainly from Salmo salar in the European and North American Atlantic and from Oncorhynchus spp. in the Asiatic and North American Pacific, coupled with observations by the author on material from S. salar from England and from Oncorhynchus spp. from a wide range of localities in the North Pacific, suggest that L. salmonis (Krøyer, 1838) is the only species found on salmonids from both oceans. The differentiation of L. uenoi Yamaguti, 1939 as a distinct species on Pacific salmon seems to be the result of incorrect or inadequate early descriptions of L. salmonis.
