“…Originally, it was identified as C. primordialis (Haeckel, 1872) (Borojević 1971;Mothes de Moraes 1985;Klautau et al 1994). However, considering differences in the size of the actines (holotype of C. conifera: 62.5-77.3(±9.3)-97.5/9(±1.0) µm; Haeckel measurements of C. primordialis: 100-150/8-12 µm), it was described as a new species: C. conifera.…”

In this study we analyze the calcarean sponge diversity of the Adriatic Sea, the type locality of some of the first described species of calcarean sponges. Morphological and molecular approaches are combined for the taxonomic identification. Our results reveal six species new to science and provisionally endemic to the Adriatic Sea (Ascandra spalatensis sp. nov., Borojevia croatica sp. nov., Leucandra falakra sp. nov., L. spinifera sp. nov., Paraleucilla dalmatica sp. nov., and Sycon ancora sp. nov.), one species previously known only from the Southwestern Atlantic (Clathrina conifera), and three already known from the Adriatic Sea (Ascaltis reticulum, Borojevia cerebrum, and Clathrina primordialis). We confirm the presence of the alien species Paraleucilla magna in the Adriatic and again record Clathrina blanca, C. clathrus, and C. rubra. We emend the description of the genus Ascaltis, propose a lectotype for Borojevia cerebrum and synonymise B. decipiens with B. cerebrum. A checklist of all calcarean species previously and currently known from the Adriatic Sea (39 species) is given. The Central Adriatic is indicated as the richest calcarean sponge fauna sector; however, the biodiversity of this class is underestimated in the whole Adriatic Sea and new systematic surveys are desirable.

“…Until now, this species was considered endemic to Brazil (Borojević 1971;Mothes de Moraes 1985;Klautau et al 1994;Monteiro & Muricy 2004;Muricy & Hajdu 2006;Lanna et al 2007). Originally, it was identified as C. primordialis (Haeckel, 1872) (Borojević 1971;Mothes de Moraes 1985;Klautau et al 1994).…”

“…In the 1970s, another foreign oceanographic expedition, conducted by Oxford University, promoted dives for scientific purposes in Brazil. Since then, Brazilian researchers have published studies using biological material collected in these first expeditions, such as Mothes de Moraes (1985), who described the fauna of marine sponges in the upwelling region of Cabo Frio, RJ. Moreover, educational institutions and research focused on marine areas began to grow and, due to this combination of factors, the scientific production and training of researchers in marine biodiversity in Brazil has advanced significantly.…”

Abstract:The sponges (Porifera) are one of the oldest extant metazoans, but still easily found in a wide variety of aquatic environments. They are key components in several ecosystems, directly influencing the quality of water in their habitat. In recent times, these organisms have become one of the most productive groups in providing new compounds with bioactivity or unusual structures. However, sponges are historically considered a group of complex taxonomy, and systematic discussions at order level or even about the monophyly of the group are still common. This situation began to change markedly in the last decade, with multinational initiatives aimed at providing a more solid taxonomic basis. In Brazil, this process was accompanied by the publication of identification guides of the native species. Starting from the sporadic data available in earlier periods, several initiatives were specifically targeted at the survey of Porifera species, particularly in coastal regions. Such actions now provide the researchers with a knowledge base far more comprehensive than that available a decade earlier. In the ten years since the last checklists for the São Paulo State were published, there was a significant change in the scenario. As verified by this study, the period was undoubtedly the most prolific regarding the knowledge of the local spongiofauna. Resumo: 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 acompanhado pela publicação de guias de identificação para as esponjas do nosso litoral. Partindo dos dados esporádicos disponíveis em períodos anteriores, diversas iniciativas foram feitas especificamente voltadas para o levantamento das espécies de Porifera, principalmente nas regiões costeiras. Tais ações fornecem atualmente aos pesquisadores iniciantes uma base de conhecimento bem mais abrangente do que a disponível na década anterior. Nos dez anos passados desde as últimas listagens feitas para o Estado de São Paulo, houve uma alteração significativa no quadro apresentado. Conforme pôde ser verificado neste trabalho, o período foi sem sombra de dúvida o mais prolífico no que se refere ao conhecimento da espongiofauna local. Palavras-chave: Porifera, biota paulista, Programa BIOTA/FAPESP.
