Taxonomic status of cestodes of the genus Paracaryophyllaeus Kulakowskaja, 1961 (Caryophyllidea: Caryophyllaeidae)

A taxonomic revision of cestodes of the genus Paracaryophyllaeus Kulakowskaja, 1961, parasites of cobitid fishes, has been performed. Three species (Paracaryophyllaeus gotoi (Motomura, 1927), P. kulakowskae sp. n., and P. misgurni sp. n.) are considered valid species; two are described as new species. P. dubininorum Kulakowskaja, 1961 is a young synonym of P. gotoi. The taxonomic status for P. gotoi sensu Scholz, 1989, P. gotoi sensu Scholz et al., 2001, and Paracaryophyllaeus sp. 1 and Paracaryophyllaeus sp. 2 (described in present work) needs specification.
