Name

Tetragonopterus Cuvier, 1816: 166

Type species: Tetragonopterus argenteus Cuvier, 1816

Etymology: "square-finned", from Greek tetra = 'four', gonio = 'angle', and pterus = 'fin'. Originally a misspelling of Tetragonoptrus, meaning 'quadrate', 'rhomboidal', e.g. "of square appearance" (Latin: quadratus aspectu.)
