Etymology: Pentanchus: penta, from pente (Gr.), five; -anchus, perhaps an abridgement of branchos (Gr.), gill, referring to five pairs of branchial apertures (gill slits), unique among the group of sharks (hexanchoid) in which the authors erroneously believed this shark belonged (See ETYFish)profundicolus: profundus (L.), deep; -colus (L.), dwelling in, referring to deepwater habitat (holotype taken at 1070 m) (See ETYFish).

Western Central Pacific: known from the holotype and only specimen taken from the Mindanao Sea, Philippines. Upon comparing, the holotypes of Apristurus herklotsi and this species are conspecific, thus, suggesting that Pentanchus is a senior synonym of Apristurus. But due to lack of verifiable specimens, herklotsi is tentatively retained in Apristurus.
