Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. B. Blake and H. Hagdorn 2003 | Trichasteropsid with 12 to 14 marginals in individuals of R -35-60 ram. Abactinals become progressively intercalated between, proximal, medial marginals in individuals of R >15-25 ram. Ambulacrals, adambulacrals foreshortened in at least some individuals, alternating carinate and concave adradial profiles of proximal adambulacrals suggest four rows of tube feet. Distal-most abactinals, marginals, adambulacrals enlarged, forming more or less bulbous arm tip. Adoral carina (i.e. adambulacrals abutted across the interbrachia) generally at least weakly developed in at least some interbrachia. Madreporite enlarged. |
