Etymology: Apristurus: a-, Latin privative, i.e., without; pristis, from pristes (Gr.), sawyer (but here meaning saw); oura (Gr.), tail, referring to absence of saw-toothed crest of enlarged dermal denticles along upper edge of caudal fin as found in the closely related Pristiurus (=Galeus) (See ETYFish); iterum: Name 'iterum' from the Latin adverb meaning 'again, a second time, or once more', in allusion to the discovery of a new species of Apristurus.
