Etymology: Asymbolus: Etymology not explained, possibly a-, Latin privative, i.e., without; sym-, from syn (Gr.), together or joined; bolus (L.), lump or morsel, proposed as a subgenus of Scyliorhinus (Scyliorhinidae) distinguished in part by labial fold of upper lip not hanging over lower-jaw symphysis of A. analis and A. vincenti. (See ETYFish); occiduus: Latin for western (of the setting sun), referring to its western distribution in Australian seas. (See ETYFish).
