Treatment

Genus Austriocaris Glaessner, 1931

Type species

Austriocaris carinata Glaessner, 1931 by monotypy.

Original diagnosis ( Rolfe 1969)

Carapace only known, posterior excavation arcuate or irregular, anterior margin concave or produced into small beak; posteroventral or ventromedian V-shaped furrow; surface smooth with mid-dorsal granulations or posteroventral pits, or dorso-ventrally striate.

Emended diagnosis

Thylacocephala with an optic notch occupying only the ventral part of the anterior margin, presence of a straight mid-dorsal line and a sharp postero-ventral corner.

Remarks

Rolfe (1969) inversed the orientation of the shield of Austriocaris , the posterior being identified as the anterior. This influenced his diagnosis, with the optic notch being described as a posterior notch.
