Some of the records listed for N. cf. trigoinoides above may refer to this species. PNG voucher material: CSIRO unregistered, adult male 37 cm DW, CSIRO unregistered, female 22 cm DW, Wewak, East Sepik Province, September 2017 . Remarks: Colour and genetic differences distinguish this species from N. australiae and N. cf. trigonoides . Base don coloration and CO1 sequence data, this species is most similar to and possibly conspecific with the recently described N. westpapuensis Borsa, Arlyza, Hoareau & Shen, 2017 from Cenderwasih Bay. Unfortunately this description was based almost entirely on DNA with no useful field characters provided which prevented detailed comparisons without examing specimens.
