Species related to Mormyrus hasselquist: [ 1 ] record

hasselquist, Mormyrus Lacepède [B. G. E.] 1803:622 [Histoire naturelle des poissons (Lacepède) v. 5; ref. 4930] Nile River, Egypt. Based on the style in Lacepède p. 622 this name is Latinized and predates Mormyrus hasselquistii Valenciennes 1847 as used in the current literature; current usage would suggest continuing to retain authorship as Valenciennes 1847. Both names were based on Geoffroy St. Hilaire and caschive of Hasselquist 1757:398 [ref. 30181], the latter a rejected work (ICZN Opinion 57), but hasselquistii also involved specimens and can stand on its own. •Synonym of Mormyrus caschive Linnaeus 1758. Current status: Synonym of Mormyrus caschive Linnaeus 1758. Mormyridae. Habitat: freshwater.
