Author: Eichwald, 1831
Remark: Successively a synonym of <i>Syngnathus nigrolineatus</i> Eichwald, 1831, or a subspecies of it, and of <i>Syngnathus abaster</i> Risso, 1827.  Reconsidered as a valid species since 2009 in various ichthyofaunas without compelling evidence until Zarei <i>et al.</i> (2021: Ref. 130571) used genetic characters (see the introduction for a complete history of the taxonomy).  The species needs a complete redescription.
