Examination of the holotypes, specimens in the type series and material from across their geographical ranges for Haliplus leechi Wallis and H. salmo Wallis shows that the two names are conspecific; H. salmo is placed as a junior subjective synonym of H. leechi. A sexual dimorphism in the relative eye separation is present in members of this complex, H. canadensis Wallis and H subguttatus Roberts. Preliminary data suggest that this dimorphism may also be present in other haliplid species. This dimorphism should be taken into account in constructing keys for the determination of haliplids.
