Diagnosis
Tethyidae with a discoid body. Cortex is thin, poorly developed. Surface with relatively small rounded tubercles and oscules on slight prominences in the central part of the disk. Much sediment occurs in the deeper part of the choanosome. Megascleres are represented by styles in parallel bundles ending in the tubercles, crossed by thin bundles of styles in the lower part of the choanosome at the contact with the sand layer. Megasters are oxyasters, heterogeneous in size and shape, reaching large dimensions (also 180um in diameter): Micrasters are spiny oxyasters, strongylasters, chiasters and tylasters.
