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); parvus: Latin for small, referring to its small relative size within the genus. (See ETYFish).
