Another species,\n                    <jats:italic>S. cotti<\/jats:italic>\n                    , is known from the European bullhead (\n                    <jats:italic>Cottus gobio<\/jats:italic>\n                    ); however, information on its host range, geographical distribution, and molecular data remain poorly characterized. In Siberia, plerocercoids of\n                    <jats:italic>Schistocephalus<\/jats:italic>\n                    found in sculpins were previously recorded from endemic cottid fishes of Lake Baikal and were identified as\n                    <jats:italic>S. solidus<\/jats:italic>\n                    , which is inconsistent with the known host specificity of this species. The present study aims to clarify the species identity of\n                    <jats:italic>Schistocephalus<\/jats:italic>\n                    from Siberian cottid fishes using morphological and molecular data, and to test the hypothesis of conspecificity of\n                    <jats:italic>Schistocephalus<\/jats:italic>\n                    plerocercoids from sculpin hosts across Eurasia and North America.
