Diagnosis

Reference	Diagnosis
W. S. Adkins 1928 (Austinaster)	Outline stellate-pentagonal, interradial arc moderatelly deep. Form depressed, disk thin over center, thickened at marginalia. Infero- and superomarginalia set at angle to each other, the inferior ones projecting, reducing gradually in size toward tip of ray. Both marginalia tuberculate tubercules of medium size and somewhat irregularly distributed. Marginalia devoid of ridge, grooves or other irregularities, and margins not depressed. Actinal interradial plates triangular, large. Abactinal plates small, hexagonal.
