Remarks: First recorded from PNG by Peters (1877) as Trygon sephen from New Britain. Macleay (1883a) described as a new species, Taeniura atra, based on a specimen collected from off Port Moresby; subsequently included in the synonymy of Pastinachus sephen but recently resurrected as a valid species. Caught occasionally by prawn trawlers and probably also by coastal fishers.
