The hooves on the spines are diagnostic for what Mortensen called asthenosomine echinothurioids, but this basically excludes only the Phormosoma group. Notice the dark tips of the aboral spines - these are venom-bearing tissues. There are 8 genera in the group with hooves on the spines but what ambulacral plating strongly suggests a Sperosoma or a Tromikosoma.
