Asteroidea - Paxillosida - Astropectinidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|D. B. Blake and K. Sturgeon 1995||A genus of Astropectinidae with disc comparatively large for family; interbrachial arcs angulary to weakly rounded; arm outline (as viewed from above) broadly triangular, straight-sided, abruptly tapering. Marginals well defined, small, rectangular in dorsal outline; fascioles distinct, deep, not broad. Interbrachial, medial superomarginals clearly smaller than inferomarginals, inset from abradial margin (i.e., inferomarginals forming abradial edge of arm), ossicles of two series dissimilar. Actinal ossicles numerous.|
