In conclusion, the SSU data presented here support the monophyly of two novel clades of marine haplosclerids that do not correspond to the existing taxonomic classification. The monophyly of the suborder Spongillina is supported but its inclusion in the Order Haplosclerida must now be questioned considering its close relationship with other demosponge orders.
