The systematics of the poriferan Order Haplosclerida (Class Demospongiae) has been under scrutiny for a number of years without resolution. Molecular data suggests that the order needs revision at all taxonomic levels. Here, we provide a comprehensive view of the phylogenetic relationships of the marine Haplosclerida using many species from across the order, and three gene regions. Gene trees generated using 28S rRNA,  nad1  and  cox1  gene data, under maximum likelihood and Bayesian approaches, are highly congruent and suggest the presence of four clades. Clade A is comprised primarily of species of  Haliclona  and  Callyspongia , and clade B is comprised of  H. simulans  and  H. vansoesti  (Family Chalinidae),  Amphimedon queenslandica  (Family Niphatidae) and  Tabulocalyx  (Family Phloeodictyidae), Clade C is comprised primarily of members of the Families Petrosiidae and Niphatidae, while Clade D is comprised of  Aka  species. The polyphletic nature of the suborders, families and genera described in other studies is also found here.
