Genus Anoxypristis White & Moy-Thomas, 1941

Type species. Pristis cuspidatus Latham, 1794 (replacement name).

Description. Nostrils very elongate and well separated, width subequal to internasal distance; posterior aperture very elongate and narrowly curved, not markedly oblique to anterior aperture. Anterior nasal flaps single-lobed, poorly developed, not fused to form a nasal curtain, low, with innermost edge poorly defined (joined discretely to nostril margin and about midlength of posterior aperture); anterior aperture small, directed anteroventrally and situated at lateral margin of head, innermost edge incompletely formed by short lobe-like extension of anterior nasal flap (positioned anteriorly and barely reaching across nostril aperture); posterior margin of anterior aperture bordered by long and very narrow posterolateral nasal flap that extends posteromedially as a long free lobe (almost as long as posterior aperture of nostril); posterior nasal flap narrow (width similar to posterolateral nasal flap) and base long (more than half of nostril width). Lower jaw straight or weakly undulate; skin margin forming upper lip straight or weakly concave; 2 short lateral grooves directed posteromedially from its angle; no oral groove.

Species. A. cuspidata (Latham, 1794) .
