Obruta gen. nov.

Type species. Obruta collector sp. nov.

Diagnosis. Bubaridae with oxeas as primary spicules, thickly encrusting growth habit, and very hispid surface. Slightly sinuous oxeas found near the sponge base, mixed in confusion with non-sinuous oxeas; ill-defined tracts of non-sinuous oxeas rise vertically from this base.

Etymology. Named for the copious debris often trapped by the long protruding spicules. From the latin obruta, meaning debris.
