| As esponjas (Filo Porifera) são um dos metazoários mais antigos existentes, mas ainda facilmente encontradas em uma grande variedade de ambientes aquáticos. São um componente fundamental em diversos ecossistemas, influenciando diretamente a qualidade da água em seus habitats. Em tempos recentes são um dos grupos que mais fornece novas moléculas bioativas ou com estruturas incomuns. No entanto, são historicamente considerados um grupo de taxonomia complexa e ainda são comuns discussões acerca da sistemática ao nível de ordens ou mesmo da monofilia do grupo. Este cenário começou a ser alterado de forma marcante na última década, a partir de iniciativas multinacionais voltadas a fornecer uma base taxonômica mais sólida. No Brasil, este processo foi... |

| The Porifera occurring at Alagoas State reefs (north-eastern Brazil) are still little-known, with few species listed and even fewer formally described. From a total of 48 species recorded from the state, only eight belong to the Poecilosclerida, including those (re)described in this study. Here we describe a new species, Mycale (Mycale) alagoana sp.nov., and redescribe two species: Lissodendoryx (Lissodendoryx) isodictyalis (Carter, 1882) and Mycale (Naviculina) diversisigmata Van Soest, 1984, both first formal redescriptions from the Southwestern Atlantic. Additionally, Mycale (Aegogropila) escarlatei Hajdu et al., 1995 is here reported from Alagoas for the first time, in discussing the difficulties inherent to recognition in the field of small crustose... |

| Phorbas capixaba sp. nov. is described from 54 m depth off Guarapari, diagnosed by its two clear-cut categories of isochelae from Phorbas spp. known from the Western Tropical Atlantic. Four nomina nova are proposed for homonyms in Phorbas spp.: P. bergmontae nom. nov. for P. areolatus Bergquist & Fromont, 1988, preoccupied by P. areolatus (Thiele, 1905); P. burtoni nom. nov. for P. arborescens sensu (Burton, 1956), preoccupied by P. arborescens (Ridley, 1884); P. hechteli nom. nov. for P. ramosus (Hechtel, 1983), preoccupied by P. ramosus (Lendenfeld, 1888; in part - composite species); P. tanitai nom. nov. for P. purpureus (Tanita, 1961), preoccupied by P. purpureus (Carter, 1886). Three little known species are redescribed: Aplysina alcicornis... |

| A new species of Mycale Gray, 1867 bearing raphidotoxas is described from the Namibian coast (SE Atlantic). Mycale (Aegogropila) kolletae sp. n. is characterized by having raphidotoxas up to 590 µm long, three distinct categories of anisochelae, two categories of sigmas, very small raphides, and most of all, by toxas serrated in an unusual pattern (on the inner parts of all three bends). Mycale magnirhaphidifera Van Soest, 1984 is redescribed from the Brazilian coast, based on a population from the northern São Paulo State coastline. The remaining two species with raphidotoxas, viz. Mycale rhaphidotoxa Hentschel, 1912 and M. mannarensis Thomas, 1968 are revised. Levi's (1963) record of Carmia macilenta (Bowerbank, 1866) for the South African coast was... |

| Two new Mycale (Naviculiiia) Gray, 1867 are described, M. (N.) arcuiris sp. n. and M. (N.)purpurata sp. n., from the Paulista Biogeographic Province (Southwestern Atlantic). They both occur in the São Sebastião Channel area (São Paulo stale coast), the former extending its known distribution to "Arvoredo Marine Biological Reserve" (Santa Catarina state coast). The new species are sibling and differ from each other by a series of very small traits, the most notorious being live-color: yellow, orange, green, white, grey and beige, always light, in M. (N.) arcuiris sp. n. and bordeaux in M. (N.) purpúrala sp. n. Both species are compared with other known M. (Naviculiiia). Mycale (Aegogropila) henlscheli Sim & Lee, 2001 is transferred to subgenus... |
