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... |

A new species of porcellanid crab, Polyonyx vermicola, belonging to the P. sinensis group is described from Selangor, Peninsular Malaysia. The species is an obligate commensal of tubes of the chaetopterid worm Sasekumaria selangora Rullier, 1976 (Polychaeta). Polyonyx vermicola is differentiated from all congeners by its small size, possessing a more rectangular carapace, proportionately longer carpus on the larger cheliped, strongly gaping cheliped fingers, the tips of which are turned outwards, the outer surface of each cheliped fingers lined with a row of small granules, and having the ventral margin of the third ambulatory propodus armed with strong spinules. |

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. |

Spirobranchus corrugatus, a little known species, is redescribed based on ample material from Australia, Indonesia, Japan and the Seychelles. The species is characterized by a seemingly porous tube, sunk into the substrate. Characteristically, the opercular plate shows a number of radial ridges on its distal surface, resembling Middle Miocene microfossils from Poland. The ventral rim of the opercular bulb of Sp. corrugatus bears numerous ocelli, with single lenses. A comparison with similar species is given. |

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. |

from the continental shelf of the Gulf of California lacking thoracic neuropodial hooks confirmed that a new species, Leitoscoloplos multipapillatus, described herein, is present along with Leitoscoloplos panamensis (Monro. 1933), already recorded there. The new species is closely related to L. panamensis, but can be clearly separated from this, and all other species of Leitoscoloplos, by the unique presence of up to 14 stomach papillae per chaetiger. A third taxon was identified, Leitoscoloplos sp., which is morphologically indistinguishable from L. panamensis, except for the presence of 1-2 stomach papillae on 1-2 segments, a feature that although important was not considered significant enough to erect a new species. Morphometric analyses between the... |

La subfamilia Anoplosyllinae posee palpos fusionados en la base, sin surco central, tres antenas y dos pares de cirros tentaculares, faringe recta, corta y desarmada. Antenas, cirros tentaculares y primeros cirros dorsales lisos, el resto pueden ser lisos o semiarticulados. La subfamilia Eusyllinae posee palpos fusionados, parcialmente o libres, órganos nucales frecuentemente largos y diferenciados, uno o dos pares de cirros tentaculares, cirros dorsales que varían en longitud, usualmente lisos, cirro ventral presente, faringe usualmente derecha, con dientes o inerme. El objetivo de este estudio fue revisar material tipo y no tipo de las especies registradas para el Gran Caribe. Fueron examinados 186 ejemplares; 135 colectados en el Caribe mexicano y 51... |

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... |

During the Amsterdam Expedition to Ascension Island in 1989 eighteen species of polychaetes were collected, fifteen of which were already known to science. One could not be identified to species level and two were new to science: Aricidea (Aedicira) ascensionensis n. sp. and Notodasus arenicola n. sp. Four of the known species are widely distributed, three are circumtropicalsubtropical and one has a tropical-subtropical distribution in the Pacific and in the Atlantic Ocean. Another species is recorded from different regions in the Atlantic Ocean. The rest of the species were – until now – only known from their type localities, viz. West Indies, Angola, Persian Gulf, Galapagos Islands, and South Shetland Islands. |

Ventral thoracic bloodvessel-patterns were defined in a random sample of 152 living specimens of the Apomatus/Protula- complex. Two main patterns and a derived one could be recognized. Eight characters, often used in Serpulid taxonomy and retraceable in preserved material, were determined too: e.g. presence or absence of an operculum and pattern of thoracic setae. These parameters were correlated to the vascular patterns. It was shown that (a) all operculate specimens possess a vascular system of one main pattern; 86% of those closely studied have "Apomatus-setae" at least from setiger 4 onwards; all have radioles with paired rows of compound eyespots. (b) The non-operculate specimens generally possess the other main vascular pattern; the thorax often has... |
