Macruronus

Macruronus is a genus of gadiform fish, the only member of the family Macruronidae. It was formerly placed in the Merlucciidae.^[1][2][3][4] Most are found in southern oceans off Argentina, Chile, South Africa, Australia and New Zealand, but M. maderensis (which is in need of taxonomic review) is only known from Madeira.^[2][5] Members of this genus reach 1–1.3 m (3.3–4.3 ft) in length depending on the exact species involved.^[2]

Species

The currently recognized species in this genus are:^[2]

• Macruronus capensis D. H. Davies, 1950 (Cape grenadier, South African straptail)
• Macruronus maderensis Maul, 1951
• Macruronus magellanicus Lönnberg, 1907 (Patagonian grenadier)
• Macruronus novaezelandiae (Hector, 1871) (Blue grenadier)

Note that the Catalog of Fishes considers Macruronus capensis and M. magellanicus (following Leslie and colleagues (2018) and others^[5]) as junior synonyms of M. novaezelandiae.^[6] This leaves the genus with one confirmed species and one with uncertain status.^[5]
