Remarks: First recorded from PNG by Herre (1936) from Koragu in the Sepik River based on an expedition there in 1929; a specimen deposited at the ZMB collection in Berlin collected from Ramu River in either 1896 or 1899. White et al. (2017a) summarised published and unpublished sawfish records for PNG; most reports refer to just sawfish although many are attributable to this species. An additional 9 specimens (6 registered lots) from the KFRS collection are considered lost or destroyed; all collected in the mid 1960’s. Dried fins observed from coastal fisheries during recent surveys in the Gulf and Western Provinces; whole specimen observed in prawn trawl bycatch in 2014. Considered depleted from some river systems in PNG but more information is urgently required.
