| ABSTRACT A new species of orbiniid, Scoloplos maranhensis sp. nov., is described from a tropical mangrove (Quebra Pote, state of Maranhão, Brazil, 02°41.344’S; 44°12.604’W) along with a comparative table with all Scoloplos species. The main distinguishing characters of S. maranhensis sp. nov. are thorax with 12 chaetigers, neuropodia from first chaetiger, notopodia and neuropodia without papillae, conical branchiae from 12th chaetiger to the end of the body, being larger and more robust in the anterior segments. Thoracic notopodia with seven crenulated capillary chaetae and abdominal notopodia with furcated and capillary chaetae. Thoracic neuropodia rounded with two crenulated capillary chaetae and six slender-smooth hooks, abdominal neuropodia with a... |

| Hypotheses about the phylogenetic relationships within Questidae, and the relationships of this taxon with Clitellata using parsimony analysis of 35 external and internal morphological characters of 36 terminal taxons are presented. The results show the position of Questidae within Scolecida and Clitellata. Within the Polychaeta, Clitellata is the sister group of the Questidae. The results also indicate that the Scolecida, Microdrilli, Polychaeta, Oligochaeta and Tubificidae are paraphyletic. Clitellata, Megadrilli, Questidae, Hirudinae are monophyletic. |

| The polychaete composition and distribution within mussel beds were studied in order to assess organic pollution due to domestic sewage in a rocky shore of Mar del Plata (Argentina) during 1997. Four stations and a control site were randomly sampled around the local effluent. Quantitative data on polychaetes, as well as sediment accumulated among mussels and its organic carbon content were measured. Polychaete distribution patterns are related to the organic matter gradient, being Capitella cf. capitata, Neanthes succinea (Frey & Leuckart, 1847) and Boccardia polybranchia (Haswell, 1885) the dominant indicator species close to the effluent. At medial distances, the cirratulids Caulleriella alata (Southern, 1914) and Cirratulus cirratus (Müller,... |

| Håkon Mosby mud volcano (HMMV) is one of the most active and most studied seep sites in European waters. Many authors have described its thermal activity, dynamic of mud flows, and geochemical and microbial processes. It is characterised by a concentric zonation of successive biogenic habitats related to an activity and geochemical gradient from its centre to its periphery. Around the central area covered by mud flows, white and grey microbial mats occur among areas of bare sediment, whereas siboglinid tubeworm fields of Sclerolinum contortum and/or Oligobrachia haakonmosbiensis colonise the peripheral areas. The meiofaunal community is known to be structured among habitats, but the macrofauna has rarely been investigated and has never been sampled in... |

| Polynoidae contains ~900 species within 18 subfamilies, some of them restricted to the deep sea. Macellicephalinae is the most diverse among these deep-sea subfamilies. In the abyssal Equatorial Pacific Ocean, the biodiversity of benthic communities is at stake in the Clarion-Clipperton Fracture Zone (CCFZ) owing to increased industrial interest in polymetallic nodules. The records of polychaetes in this region are scarce. Data gathered during the JPI Oceans cruise SO239 made a significant contribution to fill this gap, with five different localities sampled between 4000 and 5000 m depth. Benthic samples collected using an epibenthic sledge or a remotely operated vehicle resulted in a large collection of polynoids. The aims of this study are as follows:... |

| Macrofauna are an abundant and diverse component of abyssal benthic communities and are likely to be heavily impacted by polymetallic nodule mining in the Clarion-Clipperton Zone (CCZ). In 2012, the International Seabed Authority (ISA) used available benthic biodiversity data and environmental proxies to establish nine no-mining areas, called Areas of Particular Environmental Interest (APEIs) in the CCZ. The APEIs were intended as a representative system of protected areas to safeguard biodiversity and ecosystem function across the region from mining impacts. Since 2012, a number of research programs have collected additional ecological baseline data from the CCZ. We assemble and analyze macrofaunal biodiversity data sets from eight studies, focusing on... |

| A new species of Eunicidae, Marphysa victori sp. n., has been identified from Arcachon Bay, Bay of Biscay, NE Atlantic. This new species, belonging to the sanguinea complex, is characterised by branchiae with long filaments from chaetigers 26–34, the presence of four types of pectinate chaetae with first ones present from chaetiger 2, a large number of both pectinate chaetae and compound spinigers, and the pygidium with only one pair of pygidial cirri. An identification key for European species of the genus Marphysa is provided. |

| Phyllochaetopterus polus, a new species of the polychaete family Chaetopteridae is described. Specimens were collected at the Ashadze-1 vent field (Mid-Atlantic Ridge), from 4100-4200 m depth. P polus is the first chaetopterid reported from the Atlantic hydrothermal vents. Three chaetopterid species have been recorded from deep-sea hydrothermal vents belonging to two genera, Spiochaetopterus and Phyllochaetopterus. P polus sp. nov. is a medium-sized chaetopterid, characterized by 9 chaetigers in region A and 2 in region B; region C is usually incomplete in the specimens examined, but has at least 40-70 chaetigers. This polychaete has one pair of modified chaetae in chaetiger 4 with a pear-shaped obliquely truncated head, triangular uncini and a branched... |
