根据采集自日本北海道外阿克西湾（Akkeshi Bay）的细棘鳕Eleginus gracilis（Tilesius）的标本，重新描述了六角棘吻鱼Echinorhynchus hexagrammiBaeva，1965。18个博物馆标本保存为E。salmonisMüller，1784也被重新鉴定为E. heptyrammos stelleriTilesius，Hemitripterus villosus（Pallas），Podothecus sachi（Jordan & Snyder），扁腹蛛（Atriotes oblongus Günther）和星斑星鲽（Verasper moseriJordan &吉尔伯特）是该虫的新寄主。六芒星这种棘头虫可以与三种形态相似的物种，E。gadiZoega in Müller，1776，E. laurentianusRonald，1957和E.鲑的特征是：吻部有12-16排（通常为14排）钩，吻宽雄鱼170-240 μm，雌鱼195-270 μm，钩根雄鱼35-45 μm，雌鱼40-50 μm，粘固腺呈直线或近直线排列。
Echinorhynchus hexagrammiBaeva, 1965 is redescribed on the basis of specimens collected from the saffron codEleginus gracilis(Tilesius) in Akkeshi Bay (western North Pacific) off Hokkaido, Japan. Eighteen museum specimens deposited asE. salmonisMüller, 1784 from Japanese coastal waters were also re-examined and re-identified asE. hexagrammi.Hexagrammos stelleriTilesius,Hemitripterus villosus(Pallas),Podothecus sachi(Jordan & Snyder),Sebastes oblongusGünther andVerasper moseriJordan & Gilbert are recognised as new hosts forE. hexagrammi. This acanthocephalan can be distinguished from three morphologically similar species,E. gadiZoega in Müller, 1776,E. laurentianusRonald, 1957 andE. salmonis, by the possession of the following characters: 12–16 (usually 14) rows of hook on the proboscis, a proboscis width of 170–240 μm in males and 195–270 μm in females, a hook root length of 35–45 μm in males and 40–50 μm in females, and linearly or almost linearly arranged cement glands in males.
