Remarks: First recorded by Peters (1877) as Rhinobatus armatus  from Bougainville, presumably based on ZMB 9737, collected during an expedition on the SMS Gazelle. Commonly caught by coastal fishers in the Western and Milne Bay Provinces, and probably elsewhere. Dried fins and whole specimens observed during recent surveys.
