Diagnosis
ReferenceDiagnosis
A. Glass and M. Poschmann 2006A species of Lapworthura with stout stellate to pentagonal ossicles covering the ventral and dorsal disc. Ossicles have a distinctly scalloped surface texture. Some of these ossicles on both the ventral and the dorsal surfaces carry spines on raised tubercles. Four irregular rows of longitudinally elongated but rounded plate-like ossicles cover the dorsal surface of the arms. The ossicles of at least two rows bear spines at regular intervals along the arm. Laterals on the free arms bear four short, paddle-shaped groove spines and three long thin vertical spines. Madreporite smooth with circumferential channel.
