- Notes: A dark green-brown, crumbly, rounded volcano. Identification is tentative. It has strongyle spicules in variuos sizes, about 120 to 200 micrometers, which places it into Petrosia (Strongylophora). Ectosomal skeleton is a tangential irregular reticulation of single spicules. Internal skeleton as a ladder-like irregular unispicular reticulation. Spicules appear to be joined by spongin at the nodes; meshes are irregular because they are made up of spicules of different sizes. Spicules appear similar to Neopetrosia dominicana (Pulitzer-Finali, 1986) (originally placed under Xestospongia; not represented in this work; it has not been re-described after the original) but the external shape, the consistency and the skeleton seem to be different. We compared it to Petrosia (Strongylophora) davilai (Alcolado & Gotera, 1986), but the structure of the skeleton is different (reticulation of ascending and interconnecting multispicular tracts).
