Reassessment of multiple species of Gymnelus (Teleostei: Zoarcidae) in Pacific Arctic and boreal regions

Recently described new nominal species and resurrected species in the eelpout genus Gymnelus Reinhardt 1834 were re-assessed for validity using fresh material collected in Pacific Arctic regions and a large body of data from a previous sys-tematic review of the genus. The analysis reported here incl...

Description
Summary:Recently described new nominal species and resurrected species in the eelpout genus Gymnelus Reinhardt 1834 were re-assessed for validity using fresh material collected in Pacific Arctic regions and a large body of data from a previous sys-tematic 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 mor-photypes for which there is some evidence of difference in ecological preference, but the available environmental data are not robust enough to firmly identify or verify ecophenotypes.
