Remarks: First recorded from PNG by Filewood (1973) as Neotrygon (?) uhlenbergi; the specific names comes from Dasybatis uylenburgi Giltay, 1933 , recently considered a junior synonym of Brevitrygon walga (Müller & Henle, 1841) . Common in the bycatch of the Gulf of Papua prawn trawl fishery. Probably restricted to the southernmost regions of Papua, from Orangerie Bay westwards.
