“…In addition, H. ( Re .) portroyalensis has toxas (Jackson et al ., 2006), and H. ( Re. ) tubifera has a very distinctive shape, with oscular tubes elevated up to 5 cm, and many thin proliferations branching from the sponge body (de Weerdt, 2000).…”

Two new species of Haliclona (Chalinidae, Haplosclerida) are described here from Brazilian oceanic islands and the coast of Ceará State. They derive from collections undertaken between 1999 and 2014, and materials are deposited in the Porifera collection of Museu Nacional in Rio de Janeiro (MNRJ). Haliclona (Halichoclona) insularis sp. nov. can be distinguished from other Haliclona spp. in the western Atlantic by the combination of surface with light to deep red colour intermixed with white to beige areas (occasionally completely beige), white to beige choanosome, small fistular outgrowths, fragile consistency and blunt oxeas (90–175 × 1–5 μm) with irregular tips. Haliclona (Soestella) moraesi sp. nov. is the only western Atlantic species of Haliclona with the combination of thickly encrusting to cushion-shaped habit, purple or light pink colour, and a dense (sub)isotropic skeleton with rounded meshes, and without microscleres. Several attempts to amplify COI mtDNA and 28S C2–D2 rRNA for both species were unsuccessful, in spite of the initial successful extraction of genomic DNA. The number of Haliclona spp. known from the Brazilian coast is now 17. The long gap between species collection and formal description supports the concept of the taxonomic impediment, which is particularly marked in speciose taxa with little morphological disparity, as observed in Haplosclerida.

Haliclonais an unusually species-rich genus in Porifera, with more than 400 species described. In spite of many subgenera used in the taxonomic housekeeping of these sponges, over half of them remain unassigned to a subgenus, thus encouraging a wide range of redescriptions and taxonomic revisions of materials from all around the world. In this paper, we describe two newHaliclonaspp. collected at Pernambuco, Alagoas and Bahia States (north-eastern Brazil, between 08°46′S and 13°56′S).Haliclona(Reniera)chlorillasp. nov. is a dark green or black coloured, delicately-branched species; andHaliclona(Soestella)peixinhoaesp. nov., a beige-coloured, tubular species, where tubes frequently bear large thorns and possess a conspicuous sub-superficial meandering reticulation. These species highlight the importance of includingex-situcollections in compiling baseline data, as both were already present in scientific collections by the 1980s and 1990s.

In this paper we describe two species of the cosmopolitan sponge genus Haliclona from Rio de Janeiro State, SE Brazil, one of which is new to science and the other a new record to Brazil. Haliclona (Rhizoniera) fugidia sp. nov. is brownish-pink, salmon or cream, thickly encrusting, without oscular tubes and tangential ectosomal reticulation. Choanosomal skeleton is a mostly unispicular ladder-like reticulation of oxeas, very organized near the sponge surface and denser and more disorganized in the interior of the sponge. Haliclona (Halichoclona) vansoesti de Weerdt et al., 1999 was originally described from the Caribbean. It has a very loose connection between ectosome and choanosome, a whitish translucent ectosome combined with a purplish choanosome, a cavernous structure and a friable or crispy consistency. The conspecificity of SE Brazilian and Caribbean populations of H. (Halich.) vansoesti was verified through phylogenetic analysis of small subunit 18S rRNA (18S) and mitochondrial cytochrome oxidase subunit I (COI) gene sequences. A maximum likelihood phylogenetic tree constructed with 18S sequences indicates that specimens of H. (Halich.) vansoesti from Rio de Janeiro were phylogenetically closer to the same species from the Caribbean than to other species of Haliclona. Although not available for H. (Halich.) vansoesti from the Caribbean, COI sequences of our specimens were also quite distinct from those of other Haliclona species. Molecular identification based on DNA sequences is a useful complement to traditional morphology-based taxonomy, especially in highly plastic sponges such as Haliclona spp. and other haplosclerids.
