Abralia steindachneriKotaro Tsuchiya
A. steindachneri is a relatively large species for the genus, and attains 50mm DML. It is easily recognized by the presence of a distinct arrangement of longitudinal photophore stripes on the ventral mantle, large numbers of club hooks, and a distinct eye photophore pattern. This species is broadly distributed in the Indo-West Pacific Ocean where it is associated with shelf waters.

Nesis and Nikitina (1987) downgraded the Pacific A. renschi to a subspecies of A. steindachneri.
Type locality of this species is the Red Sea. It is associated with shelf waters of the West Indian coast, Andaman Sea, Torres Strait, northern coast of western Australia, Ryukyu Islands, and the submarine banks off East Africa.
