Abstract
Black gobies (<i>Gobius niger</i>) from the Finnish Archipelago, Baltic Sea, were screened for helminth infections in summer 2020. Helminths were identified morphologically and/or molecularly. Altogether 26 novel sequences were generated and analysed using maximum likelihood estimation. Morphological and phylogenetic analyses based on mitochondrial genes revealed the presence of 8 species belonging to the Digenea (<i>Diplostomum mergi</i> Lineage 3), Cestoda (<i>Bothriocephalus scorpii</i>), Nematoda (<i>Contracaecum rudolphii</i> A, <i>Cucullanus</i> sp. and <i>Hysterothylacium aduncum</i>), and Acanthocephala (a putative new species of <i>Corynosoma</i>, <i>Corynosoma semerme</i> and <i>Neoechinorhynchus</i> sp.). Phylogenetic and comparative sequence analyses revealed that the putative new acanthocephalan species is closely related to <i>C. neostrumosum</i> described from the Caspian seal, <i>Pusa caspica</i>, in the Caspian Sea. The black goby represents a new host record for four parasite species (<i>Diplostomum mergi</i> Lineage 3, <i>Contracaecum rudolphii</i> A, <i>Corynosoma semerme</i> and <i>Corynosoma</i> sp.). The Finnish Archipelago is a novel locality record for three species (<i>Corynosoma</i> sp., <i>Diplostomum mergi</i> Lineage 3 and <i>Bothriocephalus scorpii</i>).
