Jasmineira filatovae Levenstein, 1961, the deepest known sabellid is a Potamethus Chamberlin, 1919: redescription, new combination and generic emendation.

Jasmineira filatovae Levenstein, 1961 was described from the Bering Sea from sediments at 3812-3940 m. Later, it was reported from 6328-9735 m in the Aleutian and Japan Trenches, thus becoming the deepest sabellid ever recorded. In the present study, syntypes of J.

Catalogue of type specimens deposited in the Polychaeta Collection of the Universidad Autónoma de Nuevo Léon (Mexico).

Background: In Mexico, there are six scientific collections of polychaetous annelids. The "Colección Poliquetológica" from the Universidad Autónoma de Nuevo León houses one of the three most important collections of annelids in the country, based on a number of lots and number of type materials deposited, as well as geographical coverage.

New Information: A catalogue of type materials of polychaete annelids housed at the "Colección Poliquetológica" from the Universidad Autónoma de Nuevo León (México) is presented for the first time.

Re-description of Monro, 1937 (Annelida, Syllidae), with the establishment of a new species from western Mexico.

Background: Monro, 1937 is a syllid genus, currently composed of four species: Monro, 1937 from the Arabian Sea, (Chlebovitsch, 1959) from the Kurile Islands, Imajima & Hartman, 1964 from Japan and Capa, San Martín & López, 2001 from the Pacific coast of Panama. The distribution of is circum-tropical to temperate waters, but the presence of species complexes has been suggested. In order to clarify the distribution of in many areas of the world, a re-description, based on examination of the type material, is required as a first step to a better understanding of its diagnostic features.

An abundant new genus and species of fan worms (Polychaeta: Sabellidae) from Hawaii.

A new genus and species of Hawaiian sabellid polychaete, Euchonoides moeone n. gen. et n.

Tubicolous polychaete worms (Annelida) from Bahía de Chamela Islands Sanctuary, Mexico, with the description of a new bamboo worm.

Background: The islands and islets of Bahía de Chamela, in the Eastern Tropical Pacific, were declared as the first marine sanctuary in Mexico and has been protected since 2002. Their marine biodiversity has been documented in a series of papers in the last decade, but only three species of polychaete worms have been reported.

New Information: Sixteen species of sedentary polychaete worms belonging to the families Maldanidae, Oweniidae, Sabellariidae, Sabellidae and Serpulidae are reported to the Bahía de Chamela Islands Sanctuary, 15 of these species constituting the first records in the area.

Fan worms (Annelida: Sabellidae) from Indonesia collected by the Snellius II Expedition (1984) with descriptions of three new species and tube microstructure.

The Indonesian archipelago is one of the most diverse regions in the marine World. Many contributions on polychaete worms have been published since the Dutch Siboga Expedition to the Indonesian archipelago at the end of the 19th century. In this study, we examined specimens of Sabellidae , collected during the Snellius II Expedition (1984) to Indonesia, carried out by the Dutch Research Vessel (RV) "Tyro" and the Indonesian RV "Samudera".

Catalogue of Notomastus M. Sars, 1851 (Annelida, Capitellidae) and the description of a new species from the Gulf of California.

Capitellids are burrowing, earthworm-like polychaetes. The taxonomy within the group presents significant difficulties, due in part to their relative simplicity. In this study, a catalogue of the capitellid genus Notomastus M.

A new species of (Annelida, Sabellida, Sabellidae) from the Ariake Inland Sea, Kyushu, Japan.

A new species of the sabellid polychaete genus Fitzhugh, 2002, is described from Ariake Inland Sea, Kyushu, Japan. is a small genus, composed of three species worldwide. Its distinctive feature is the presence of foliaceous flanges at the distal ends of the radioles.

Clarifying the taxonomic status of the alien species Branchiomma bairdi and Branchiomma boholense (Annelida: Sabellidae) using molecular and morphological evidence.

This study was performed to analyse the genetic and morphological diversity of the sabellid annelid genus Branchiomma, with special emphasis on a taxon so far identified as Branchiomma bairdi. This species, originally described from Bermuda, has frequently been reported as an invader in the Mediterranean, the Atlantic and the Eastern Pacific, but recent observations have raised some taxonomic questions. Samples of this taxon were collected from five sites in the Mediterranean Sea, two sites in the original distribution area of B.

What is (Sabellidae)? Comparisons of populations from Britain, Iceland and Canada with comments on and .

A neotype of Amphitrite Müller (1771) is established and re-described, using material collected in 2001 from near the type locality on the southwest coast of Iceland. We examined material from Iceland, Nova Scotia and Newfoundland, identified as Pseudopotamilla reniformis, showing scissiparity and commonly found in aggregations within kelp holdfasts or amongst encrusting fauna. By contrast, scissiparity has not been seen in a population recorded as P.

Aracia sinaloae sp. n., a new brooding, simultaneous hermaphroditic fan worm from southern Gulf of California (Polychaeta: Sabellidae).

Currently, only two species are known in the sabellid genus Aracia: A. riwo (Rouse, 1996) and A. heterobranchiata (Nogueira, López & Rossi, 2004).

Parasabella Bush, 1905 is reintroduced as a replacement name for Demonax Kinberg, 1867 (Annelida: Polychaeta: Sabellidae) which is a junior homonym of Demonax Thomson, 1860 (Insecta: Coleoptera: Cerambycidae).
