1. A new species of Exogone Ørsted, 1845 (Annelida: Syllidae: Exogoninae) from Brazilian waters
Abstract We describe herein a new species of the abundant polychaete family Syllidae, Exogone brasiliensis sp. nov. The new species is characterized by a peculiar morphology of anterior body falcigers, with shafts and blades modified specially in chaetigers 1 and 2; falcigers until chaetiger 5 different from those of the rest of the body; and dorsal simple c

2. Association between deep-water scale-worms (Annelida: Polynoidae) and black corals (Cnidaria: Antipatharia) in the Southwestern Atlantic
ABSTRACT Polynoid scale-worms have been found living as commensals with deep-water antipatharians (commonly known as black corals) in the Potiguar Basin, off Rio Grande do Norte State, Northeastern Brazil. In this paper two polychaete species and four black corals species are redescribed. Benhamipolynoe cf. antipathicola and Parahololepidella cf. greeffi, an

3. Substrate preference by the porcelain crab Pachycheles monilifer (Crustacea, Anomura): the bryozoan Schizoporella errata or the polychaete Phragmatopoma caudata?
Differences on reproductive performance between two sampling points of the porcelain crab Pachycheles monilifer from Ubatuba (São Paulo, Brazil), one from Itaguá Beach (living on Schizoporella errata) and the other from Grande Beach (living on Phragmatopoma caudata) has been previously observed. Therefore could be expected a specific behavior in substrate

4. Biologia populacional do poliqueta exogone (exogone) breviantennata Hartmann-Schröder, 1959 (Syllidae: Exogoninae) / Population biology of the polychaete exogone (exogone) breviantennata Hartmann-Schröder, 1959 (Syllidae: Exogoninae)
The study of the syllid Exogone (Exogone) breviantennata was conducted in two soft bottom beds of the mytilid Mytella charruana at Camaroeiro and Cidade beaches, located on the northern coast of São Paulo. To characterize the study areas, samples were taken monthly between february 2006 and february 2007 at Camaroeiro, and between april 2006 and april 2007

5. Population dynamics and reproductive strategy of Scolelepis goodbodyi (Polychaeta: Spionidae) in a subtropical atlantic beach
The population dynamics and reproductive strategy of the polychaete Scolelepis goodbodyi (Jones, 1962), were investigated between June 2009 and May 2010 at Manguinhos beach, southeastern, Brazil. A total of 9,242 individuals were collected. The density did not differ significantly from one month to another. The estimated values of the growth, recruitment, an

6. Comunidades de Polychaeta (Annelida) da plataforma continental ao largo de Santos, SP: Composição, distribuição e estrutura trófica / Polychaetes Communities from continental shelf offshore of Santos, Brazil: composition, distribution and trophic structure
A composição e distribuição de poliquetas foram estudadas na região da plataforma continental sudeste brasileira adjacente à Baixada Santista (Projeto temático ECOSAN), sendo realizadas coletas em 21 estações, durante dois períodos, por meio de um \ box-corer\ (0.09m2). Poliqueta foi o grupo dominante da macrofauna, totalizando 16.274 indivíduos e

7. Morphological variations caused by fixation techniques may lead to taxonomic confusion in Laeonereis (Polychaeta: Nereididae)
The nereidid polychaete Laeonereis acuta (Treadwell, 1923) is either considered to be a valid species, or a synonym of Laeonereis culveri (Webster, 1879). The species epithet, acuta, refers to the acuminate anterior region of the body followed by a widening that is visible up to the 10th setiger. The relative width of the anterior region of the body, however

8. A new species of Stratiodrilus (Polychaeta, Histriobdellidae) from freshwater crayfishes of Southern Brazil
A new species of polychaete, Stratiodrilus vilae, epizoic on Parastacus brasiliensis (von Martens, 1869) and P. defossus Faxon, 1898, is described from the State of Rio Grande do Sul, southern Brazil. The new species has one pair of long, anal, conical ventral lobes, one on each side of the anus, claspers in the males, and one pair of tubercles in each of th

9. Polychaete assemblage of an impacted estuary, Guanabara Bay, Rio de Janeiro, Brazil
Trinta e oito estações foram amostradas na Baía de Guanabara, Rio de Janeiro, Brasil, no intuito de descrever a diversidade e biomassa de poliquetas sublitorais. As coletas foram realizadas em dois períodos distintos do ano: seco (Setembro 2000) e chuvoso (Maio de 2001). A distribuição espacial dos poliquetas sublitorais demonstrou ser nitidamente hete

10. Postlarval development of Nicolea uspiana (Polychaeta: Terebellidae)
The postlarval development of Nicolea uspiana (Nogueira, 2003), a small intertidal terebellid polychaete from rocky habitats on the southeastern and southern Brazilian coast, was studied based on postlarval, juvenile and adult specimens. The specimens, ranging from 8 to 43 segments, were collected between May 2006 and May 2007. The youngest postlarval specim

11. PolidorÃdeos (Polychaeta: spionidae) em Crassostrea rhizophorae (Mollusca: bivalvia) de cinco rios da costa pernambucana
The Crassostrea rhizophorae occurs along the coast of Brazil serving as food to coastal communities and its production helps the local socio-economic development. Polydiariosis is one of several diseases in the world oyster culture. This disease is caused by a polychaete which drills the shell and inhabits a mud blister inside the oyster; thus, the oysterâs

Os recifes de arenito constituem um ambiente consolidado com alta de diversidade de fauna e flora, no qual os poliquetas representam um grupo importante. Este estudo teve como objetivo contribuir para o conhecimento da biodiversidade de anelídeos poliquetas da costa cearense e estudar a distribuição espacial desses organismos em substratos consolidados.
