Issue
Issue on validity of subspecies: subspecies considered as valid in FB, elevated to species rank as Oxyporhamphus micropterus (Valenciennes, 1847) in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697). Please send references, or more studies are needed.
Environment: milieu / climate zone / depth range / distribution range
