Abstract

alagoana sp.nov. and two new formal records of Porifera (Demospongiae, Poecilosclerida) from the shallow-water reefs of Alagoas (Brazil). Biota Neotrop. 11(1): http://www.biotaneotropica.org.br/v11n1/en/abstract?article+bn02411012011. Abstract: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

Two new shallow-water species ofHaliclonafrom north-eastern Brazil (Demospongiae: Haplosclerida: Chalinidae)

“…Recent taxonomic effort dedicated to sponges of reef ecosystems in the north-east Brazilian geopolitical region has been rewarding in terms of new records and species found (Cedro et al, 2007(Cedro et al, , 2011(Cedro et al, , 2013Peixinho et al, 2007;Hajdu et al, 2011;Barros et al, 2013;Sandes & Pinheiro, 2013). The two new Haliclona spp.…”

First records of the order Polycladida (Platyhelminthes, Rhabditophora) from reef ecosystems of Alagoas State, north-eastern Brazil, with the description ofThysanozoon alagoensissp. nov.

“…On the north-eastern Brazilian coast, such as in the state of Alagoas, reef ecosystems are abundant and have a rich biological diversity (Correia & Sovierzoski, 2009). These reefs include a benthic fauna, which provide various natural substrates for the Polycladida, composed mainly of sponges (Cedro et al ., 2007, 2011, 2013; Bispo et al ., 2014), corals (Correia, 2011) and bryozoans (Vieira et al ., 2007, 2008, 2010). A variety of algae also provides habitats for numerous associated organisms (Santos & Correia, 1994, 1995, 2001), which are important environments for flatworms and other small invertebrates such as opisthobranch molluscs (Padula et al , 2012) and echinoderm brittle stars (Lima et al , 2011, 2013).…”

Polyplacophora (Mollusca) from reef ecosystems and associations with macroalgae on the Coast of Alagoas, Northeastern Brazil

“…Reef ecosystems on the coast of northeastern Brazil, such as those in the state of Alagoas, have a rich biological diversity (CORREIA & SOVIERZOSKI 2009), including the fauna associated both with seagrasses and macroalgae, with numerous species of molluscs (RIOS 2009), many of which belong to the subclass Opisthobranchia (PADULA et al 2012), some species of Ophiuroidea (LIMA et al 2011(LIMA et al , 2013, and many sponges with new species (BISPO et al 2014, CEDRO et al 2011. The reef ecosystems are abundant in Alagoas' coastal region, including coral reefs and sandstone reefs (CORREIA 2011), which provide various natural substrates for the Polyplacophora.…”
