Austrobela micraulax is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae.
Description The height of the shell reaches up to 26.6 mm, a diameter of 8.1 mm and 8.5 teleoconch whorls. The shell fusiform are thin, semi-transparent, narrow, and have a high spire comprising approximately 40% of total height of the shell. The suture is shallow and slightly adpressed, with a steeply descending subsutural ramp which is almost flat adapically and concave near the whorl angulation. The axial structure is broad with opisthocline ribs on the penultimate whorl.
Distribution This marine species occurs off the Tanimbar Islands, Indonesia and in the Arafura Sea, at depths between 884 m - 891 m.
Etymology The word "Micraulax" means "with small furrows" in Greek to refer to the species' spiral groove.
