Diagnosis

Reference	Diagnosis
G. Breton 1992	Long and slender arms. Radius at least 3 time longer than the interradius. Interbrachial arc parabolic. Marginal plates squarish. One row of carinal plates inserted between the superomarginal rows and joining the arm tip. External face of the marginal plates convex, slightly domed to saddle-shaped. Ornament of tiny, dense granule-pits, occasionally associated with tiny and evenly spaced tubercles. Pedicellariae unknown.
A.S. Gale 2020	Pseudarchasterids in which the interradii are strongly curved, and the interradial marginals are very narrow; the abactinal plates set between the superomarginals in the proximal arm are approximately as broad as the superomarginals.
