Description: Outer morphology: The type specimen was growing on dead Desmophyllum pertusum coral. It is spherical in shape, ~ 2.5 cm in diameter, with oscules arranged in a cluster on the upper surface of the sponge. The surface is slightly uneven owing to the presence of minute conules ( Fig. 8A).

Choanosomal skeleton: Very little spongin present, giving a lax, friable texture. Megascleres distributed w i t h o u t o r d e r; a s t e r s d i s t r i b u t e d t h r o u g h o u t choanosome.

Ectosomal skeleton: Ectosomal oxeas form bouquets around central large oxea but do not protrude much beyond the surface ( Fig. 8B). Asters form a dense ectosomal layer.
