Two new Clathria (Axosuberites) Topsent, 1893 (Demospongiae: Poecilosclerida) from Northeastern Brazil.

The genus Clathria Schmidt, 1862 is the richest genus of the family Microcionidae, but only 20 species have been recorded from Brazil until now. Clathria (Axosuberites) Topsent, 1893 is characterized by having digitate, whip-like, arborescent and flabellate growth forms, lacking echinating spicules, well differentiated axial and extra-axial skeleton, styles and/or subtylostyles as principal spicules, and microscleres palmate isochelae and toxas. The subgenus contains 19 valid species, with worldwide distribution predominantly in shallow waters. Six species occur in the Atlantic Ocean and two of them are recorded from the Western Atlantic in South America: Clathria (Axosuberites) riosae Van Soest, 2017, and Clathria (Axosuberites) marplatensis (Cuartas, 1992). Specimens analyzed in this study were collected in 2015 at Mamanguape estuary, Paraíba State, and in 2017 at Tutóia beach, Maranhão State. Here we described two new species of Clathria (Axosuberites) for the first time in Brazilian waters: Clathria (Axosuberites) aurantia n. sp. and Clathria (Axosuberites) hillenburgi n. sp.

A new species of Acanthella Schmidt, 1862 (Porifera, Demospongiae, Dictyonellidae) from northeast region, Brazil.

Acanthella Schmidt, 1862 species are characterized by choanosomal skeleton of dendritic tracts cored by interwoven sinuously bent strongyles or strongyloxeas and echinated by straight styles, oxeas or anisoxeas (Van Soest et al. 2002). The genus Acanthella comprises 33 valid species, with six known from the Atlantic Ocean (Van Soest et al. 2018). Previously, the only record for Brazil was A. flagelliformis (Van Soest Stentoft, 1988) (Muricy 2018). Species of the genus include a transition from shrub like 'Axinellas' and herbaceous species similar to the genus Suberites Nardo, 1833 (Schmidt 1862; Vosmaer 1912). Due to its heterogeneous complex of species, Acanthella has been confused with other axinellids. Similarities were seen in genera such as Phakellia (Van Soest et al. 2002), which shares spicule complement and comparable choanosomal skeletons. In the present study, we describe a new species of Acanthella from oceanographic expeditions of the northeast region of Brazil. Two specimens of Acanthella sp. nov. were collected by dredging at Ceará and Pernambuco State, Brazil. All specimens were preserved in 92% ethanol and deposited in the Porifera Collections at the Universidade Federal de Pernambuco (UFPEPOR). The taxonomic identification was carried out through analysis of spicules morphologies, using Light Microscopy (LM) and Scanning Electron Microscopy (SEM), following methods described by Hajdu et al. (2011).

New records of Biemna Gray, 1867 (Biemnidae: Biemnida: Demospongiae) and a replacement name for the species Biemna microstyla Thomas, 1984.

Biemna Gray, 1867 is characterized by stylote or exceptionally oxeote megascleres arranged in a plumoreticulate skeleton, ectosomal skeleton consists of the brushed endings of choanosomal tracts, microscleres are sigmas, microxeas, commata and raphides (Hajdu Van Soest 2002). Currently, Biemna has 55 valid species (Van Soest et al. 2018). In Brazil, three species are known from northern region (Muricy 2018): Biemna microacanthosigma Mothes, Hajdu, Lerner Van Soest, 2004, Biemna spinomicroxea Mothes, Campos, Lerner, Carraro Van Soest, 2005, Biemna trisigmata Mothes Campos, 2004. In this present study, a new name is proposed for a preoccupied combination, Biemna thomasi nom. nov. The species Biemna caribea Pulitzer-Finali, 1986 is recorded and described for the first time in Brazilian waters. Six specimens of Biemna were studied in Pernambuco and Bahia States. All specimens were preserved in 80% ethanol and deposited on the Porifera Collections at the Universidade Federal de Pernambuco (UFPEPOR).

Taxonomy of Oceanapia Norman, 1869 (Demospongiae: Haplosclerida: Phloeodictyidae) from the Brazilian coast.

The genus Oceanapia Norman, 1869 comprises 95 species worldwide, 20 from the Atlantic Ocean and seven from Brazil. Oceanapia includes sponges with hollow body and numerous fistulae; spicules are oxeas or strongyles and microscleres, if present, are sigmas or toxas. Specimens were collected by trawl at Rio Grande do Norte, Pernambuco and Pará States, Brazil. Two new species are described from the Northeast Region of Brazil: Oceanapia cordia sp. nov. and Oceanapia magna sp. nov. For two preoccupied combinations, new names are proposed, Oceanapia hechteli nom. nov. and Oceanapia topsenti nom. nov. Oceanapia stalagmitica (Wiedenmayer, 1977) is recorded and described for the first time from Brazil. A taxonomic study of seven specimens of Oceanapia from the North and Northeast region (Brazil) is given, including description, illustrations and geographical distribution. The two new species are compared with all other descriptions of Oceanapia from the Atlantic Ocean.

Description of three species of Eurypon Gray, 1867 (Raspailiidae: Demospongiae: Porifera) from the Western Atlantic and a name to replace the the secondary homonym Eurypon topsenti.

Eurypon  Gray, 1867 comprises 49 valid species distributed worldwide, and in an extensive bathymetric range. Three Eurypon species are known for Brazil, all endemic from the Northeast region. Here, we describe three new species of Eurypon. Two of which are recorded from shallow waters (down to 100 m) off Pernambuco and Paraíba States, and one species is from deep waters (157 m) off Rio Grande do Norte State. Eurypon oxychaetum sp. nov. has large subtylostyles (1025-2125 µm, length), styles, two categories of acanthostyles and oxychaetes; Eurypon potiguaris sp. nov. has large tylostyles (1000-2315 µm, length), two categories of acanthostyles, and thin oxeas; Eurypon verticillatum sp. nov. is a blue sponge with exclusive verticillate acanthostyles. The new species were compared with all other Atlantic species of the genus. A replacement name for the secondary homonym Eurypon topsenti is proposed: Eurypon pulitzeri nom. nov. The presence of verticillate acanthostyles and oxychaetes spicules are reported for the first time in Table 1 genus.

Two new Auletta Schmidt, 1870 (Axinellidae; Demospongiae; Porifera) from Brazil.

The genus Auletta Schmidt, 1970 comprises 14 valid species, with six known from the Atlantic Ocean. The genus was previously recorded for the Brazilian coast only in 1967 from surveys in Pernambuco State. The present paper describes two new Auletta from Northeastern Brazil. Auletta akaroa sp. nov. is from Alagoas State and it has a stalked tubular shape and small sinuous styles and strongyles. Auletta laboreli sp. nov. was found in Pernambuco State and it is a sponge with a cylindrical and cavernous body composed of styles with blunt and telescopic tips and sinuous strongyles. Both new species were compared with the other valid species of Auletta. The spicule complement and external morphology of the new species are discussed.

A new shallow water species of Artemisina Vosmaer, 1885 (Microcionidae, Demospongiae; Porifera) from Northeastern Brazil.

Artemisina is a microcionid characterized by lacking a distinctive choanosomal skeleton or definite spongin fibres, lacking also echinating spicules, and with a nearly radial ectosomal skeleton (Hooper 2002). The genus currently has 19 valid species, six of which are recorded from the Atlantic Ocean (Van Soest et al. 2016): A. erecta Topsent, 1904, A. incrustans van Soest et al., 2013, A. melana van Soest, 1984, A. melanoides van Soest et al., 2013, A. transiens Topsent, 1890 and A. vulcani Lévi, 1963. The present study describes a new species of Artemisina from Northeastern Brazil. Four specimens of Artemisina brasili sp. nov. were collected by snorkelling at Pernambuco State. All specimens were preserved in 80% ethanol and deposited in the Porifera Collections at the Universidade Federal de Pernambuco (UFPEPOR) and Museu Nacional of Universidade Federal do Rio de Janeiro (MNRJ).

Desmacella Schmidt, 1870 from Brazil: Description of two new species and a review of records (Desmacellida: Demospongiae: Porifera).

Three species of Desmacella Schmidt, 1870 are described from the Brazilian coast: Desmacella microsigmata sp. nov., Desmacella tylovariabilis sp. nov. and Desmacella annexa Schmidt, 1870. The new species were compared with Desmacella species from the Atlantic Ocean, which differ by the size of their spicules and by the presence of microspined sigmas. Desmacella annexa was found to have microspined toxiform microxeas and sigmas. Desmacella now contains 31 species distributed worldwide.

A new species of Lissodendoryx (Anomodoryx) Burton, 1934 (Porifera: Demospongiae: Poecilosclerida) from deeper waters off the Atlantic coast of Brazil.

The members of Lissodendoryx Topsent, 1892a are recognized by a spicule combination of ectosomal tylotes or strongyles, isodictyal reticulate architecture, arcuate isochelae and sigmas (Hofman & Van Soest 1995; Van Soest 2002). Five subgenera of Lissodendoryx, are recognized (Van Soest 2002): Lissodendoryx (Acanthodoryx) Lévi, 1961, L. (Anomodoryx) Burton, 1934, L. (Ectyodoryx) Lundbeck, 1909, L. (Lissodendoryx) Topsent, 1892a, and L. (Waldoschmittia) de Laubenfels, 1936. Lissodendoryx (Anomodoryx) is defined by the presence of a single megasclere type (Van Soest 2002). Currently has six recognized species (Van Soest et al. 2014) including two from Brazil (Muricy et al. 2011): L. (A.) recife (Boury-Esnault, 1973) and L. (A.) tylota (Boury-Esnault, 1973). In this paper, a new species of L. (Anomodoryx) is described from the mesophotic zone off Bacia Potiguar (Rio Grande do Norte State, Northeastern Brazil). The specimen was preserved in ethanol 80% and deposited in the Porifera Collection of the Universidade Federal de Pernambuco (UFPEPOR).

Two new species of Aulospongus Norman, 1878 with a key to the Atlantic species (Poecilosclerida; Demospongiae; Porifera).

We describe two new species: Aulospongus trirhabdostylus sp. nov. and Aulospongus mandela sp. nov. from Potiguar Basin (Rio Grande do Norte State, Northeastern Brazil). Both species were compared with their congeners and an identification key for the Atlantic species of Aulospongus is provided. The genus Aulospongus now contains 16 species.
