title: Reassessment of multiple species of Gymnelus (Teleostei: Zoarcidae) in Pacific Arctic and boreal regions.
abstract: Recently described new nominal species and resurrected species in the eelpout genus Gymnelus Reinhardt 1834 were reassessed for validity using fresh material collected in Pacific Arctic regions and a large body of data from a previous systematic review of the genus. The analysis reported here included both DNA barcodes and morphology. Only two species were validated: G. viridis (Fabricius 1780) and G. hemifasciatus Andriashev 1937. The latter species occurred as two morphotypes for which there is some evidence of difference in ecological preference, but the available environ-mental data are not robust enough to firmly identify or verify ecophenotypes.
