Antiguraleus abnormis is an extinct species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

[1] A.G. Beu (2009) adopted Probebela for all the southern hemisphere taxa previously referred to Antiguraleus.

(Original description) The spire of this minute and mitriform shell is produced and acute.

There are 11 longitudinal ribs on a whorl, which are crossed by three or four spiral threads in front of the angle, none behind it.

On the body whorl, the spiral threads in front of the angle are about twelve, some of which are stronger than the others.
