Types unknown according to Boeseman in Hureau & Monod (1973) . Type locality: "La Méditerranée [= Mediterranean Sea]". Local synonymy: Hexanchus griseus — Kailola, 1987 : 2 (Rabaul, New Britain); White et al. , 2018 : 34, figs (PNG). PNG voucher material: None; a specimen (KFRS E.361, Rabaul, New Britain) was destroyed. Remarks: Images of a large individual hooked by recreational sports fishers off Walindi in Kimbe Bay ( West New Britain ) on a small seamount in about 90 m depth just before being released confirm this species from PNG . Only two records of this species in PNG highlight the limited deepwater fishing in PNG waters rather than rarity of the species.
