PNG voucher material: (9 spec.) CSIRO C 850, juvenile male 151 mm DW, Haidana Island , Port Moresby, 24 Jul. 1948 ; CSIRO H 8100-01, female 275 mm DW, Motupure Island, Bootless Bay , Port Moresby, 9°31’19” S, 147°17’2” E, <1 m depth, 15 Sep. 2016 ; KFRS E.057, female 137 mm DW, Laing Island , Madang, 16 Jul. 1965 ; KFRS E.491, juvenile male 149 mm DW, Pot Island, Siassi, Umboi Islands , Morobe Province, 27 Jan. 1968 ; KFRS E.526 (2 spec.), adolescent male 243 mm DW, adult male 281 mm DW, no collection data; KFRS E.793, female 219 mm DW, KFRS E.794, female 260 mm DW, no labels, new registration number allocated April 2017, no data; ZMB 9721 , adolescent male 261 mm DW, Carteret Islands , New Ireland, 1874–1875 [probably mid-1875, SMS Gazelle survey].

Remarks: First recorded from PNG by Peters (1877) from Carteret Islands, New Ireland (ZMB 9721). Colour pattern and morphology aligns most closely to Neotrygon trigonoides ( Castelnau, 1873) but probably not conspecific; specimens from throughout PNG are required to determine whether more than one species is involved.
