Sponge white in ethanol, overgrowing some bryozoan colonies, shape of the living sponge unkown, probably of massive growth. Presence of an ectosomal skeleton unknown.

It was not possible to exactly identify this fragmentary sponge. The isodictyal skeleton and absence of microscleres are in accordance with the definition of the subgenus Haliclona (Reniera) as it is given in de Weerdt (2002). This subgenus also is reported to have occasionally strongylote spicules instead of oxeas.

The only representative of Haliclona (Reniera) we found that has strongyles about 470 µm is Haliclona (Reniera) phlox (de Laubenfels 1954). However, this species is very different from ours as it is thinly encrusting (de Laubenfels 1954) and occurs in the shallow western pacific. The possibility of this new sponge being a new species or a completely different genus cannot be absolutely excluded, but in consideration of the bad preservation state of the specimen, this question will not be resolved in this study.
