Holotype: MCZ 1117-S, Suruga Gulf, Japan; type was erroneously re-catalogued as MCZ 1455-S ( Hartel & Dingerkus, 1997 ). Local synonymy: White et al. , 2018 : 42, figs (PNG). PNG voucher material: (5 spec.) CAS 64520 (2 spec.), female 433 mm TL, adult male 564 mm TL, southwest of Bil Bil Island , north of Gogol River , Bismarck Sea , 5°18’ S , 145°46’ E , 10 May 1987 ; CSIRO H 8101-01, female 710 mm TL, off Lae , Huon Gulf , 6°44.22’ S , 147°7.55’ E , 430 m depth, 3 Nov. 2016 ; QM I 21400, female 574 mm TL, off Lae , Huon Gulf , 300 m depth, Nov. 1984 ; USNM 295139 , adolescent male 640 mm TL, southwest of Bil Bil Island , north of Gogol River , Bismarck Sea , 5°18’ S , 145°46’ E , 183 m depth, 10 May 1987 . Remarks: Compagno & Niem (1998a) first documented this species from off northern PNG . Found to be a common catch in deepwater off Lae during recent fish surveys using rod and line (F. Neira, MARSCCO, pers. comm.) in November 2016 . Has previously been referred to as Centrophorus armatus elsewhere (e.g. Chen & Cheng, 1982 ) so earlier records of C. armatus in PNG ( Filewood, 1973 ) may refer to this species.
