Sabellidae species from the Iberian Peninsula and Balearic Archipelago waters, including the
North-eastern Atlantic Ocean and Cantabrian and westernmost Mediterranean Seas, were
studied. The species Amphicorina rovignensis, Dialychone dunerificta, D. usticensis, Euchone cf.
limnicola, Euchone cf. pseudolimnicola, Megalomma lanigera, Parasabella ten...
Two symbiotic polychaetes living in brachyuran crabs in the western Mediterranean and the nearby eastern Atlantic, Iphitime cuenoti and Ophryotrocha mediterranea, were analysed to determine their phylogeographical patterns and the possible effects of known oceanographic barriers in the study area. The analysed species live in hosts inhabiting well-...
Knowledge of the Haplosyllis species in the Saudi Arabian Red Sea is rather limited, since the so-called cosmopolitan Haplosyllis spongicola and Haplosyllis djiboutiensis apparently present all along the region are the only reported species. However, both are revealed to be species-complexes, the former mostly composed of European species and the l...

The benthic Polychaete fauna associated with shallow water macroalgae assemblages from
an Asturian littoral beach (northern Spain, central Cantabrian Sea) was studied. Twenty-six
species are recorded, including the first records for Myrianida brachycephala and Nudisyllis pulligera
for the Asturian coasts and Nerilla mediterranea for the Cantabrian...
Several polychaetes species from the central Cantabrian (NE Atlantic Ocean) and western Mediterranean Seas
were studied. The Fabriciidae species Parafabricia mazzellae and Pseudofabricia aberrans are recorded for the first time
in the western Mediterranean Sea and Novafabricia infratorquata in the northeast Atlantic Ocean (Cantabrian Sea). A new
sp...
The genus Bispira Kroyer, 1856 currently belongs to the family Sabellidae Latreille, 1825 and comprises 22 species of benthic polychaetes. The monophyly of the genus is not currently assessed by any synapomorphy. Some morphological characters, including diagnostic ones defined by the type species Bispira volutacornis (Montagu, 1804), may be present...
The Red Sea, as well as some other regions of the Indian Ocean, is highly diverse, encompassing a large number of endemic species (Head 1987; Sheppard et al. 1992; Wehe & Fiege 2002). The previous knowledge on the species of Haplosyllis from this region is scarce and confusing. Initially, only H. spongicola (Grube, 1855) and H. djiboutiensis (Gravi...

Tho distribution ranges of Potymyces tragibs and Fungiacyathus cnspus aro oxtondod to tho north coast of Colombia. The distribution ranges of Schu...
Se ha estudiado la fauna de poliquetos sabélidos (Annelida) presente en aguas íbero-baleares a partir de las muestras procedentes de las cuatro campañas oceanográficas “FAUNA” (proyecto Fauna Ibérica). De forma complementaria, se han revisado las muestras procedentes de estudios previos depositadas en la colección de invertebrados del Museo Naciona...
Se ha estudiado la fauna de poliquetos sabélidos (Annelida) perteneciente al ámbito
íbero-balear, empleándose las muestras recogidas en las campañas oceanográficas
“FAUNA” (proyecto Fauna Ibérica) así como de otros estudios de menor envergadura
realizados previamente. Se han cubierto 138 localidades, diversos tipos de hábitats
marinos bentónicos (s...
It has been studied the algae associated fauna of Annelida Polychaeta at Playa de
las Llanas (Asturias, Spain). Six samples were collected from the intertidal zone,
including six species of algae: Stypocaulon scoparium, Liagora distenta, Liagora
viscida, Corallina elongata and Lithophyllum incrustans. A total of 409 individuals, 10
families and 31...
The present paper reports results from the study of a wide collection of specimens of the genus Haplosyllis (Polychaeta: Syllidae: Syllinae) obtained mainly from sponges of different Caribbean regions (Barbados, Bahamas, Belize, Bermudas, Colombia and Venezuela). Four new species are herein described and illustrated. H. aplysinicola n. sp., the mos...
Previous knowledge on Haplosyllis species from the northernmost regions of the Indian Ocean (including the Red Sea) is confusing, with H. djiboutiensis as the only species originally described in the area. This species was later synonymised with H. spongicola, which in turn was widely reported all along the region. Among these reports, two referred...
Large collections of Syllidae (Polychaeta) from around Australia housed at the Australian Museum (Sydney) have been examined and identified. Among them are seven known species of Haplosyllis Langerhans, 1879, which are here redescribed and figured: H. uncinigera (Grube, 1878), H. basticola Sardá, Paul & Ávila, 2002, H. crassicirrata Aguado, San Mar...
Four species of the genus Haplosyllis from Indonesia are herein described and illustrated. In Haplosyllis aciculata sp. nov. and Haplosyllis ingensicola sp. nov. the longest midbody cirri exceed body width and posterior parapodia have a single broad, strongly curved acicula, while in Haplosyllis tenhovei sp. nov. and Haplosyllis nicoleae sp. nov. c...
The genus Haplosyllis Langerhans, 1887 is revised based on available types and newly collected specimens. 19 species are considered as valid, five as incertae sedis and four are referred to nomina dubia. Trypanoseta (Imajima, 1966) is synonymised with Haplosyllis, as the presence of trepan is considered a non-robust taxonomic feature, affecting H....
Eunice colombia, a new species collected on the northern Caribbean coast of Colombia at depths of 300 and 500 m in soft bottoms, is described. The shape of the posterior ventral cirri, the position of the branchiae, and their length in relation to that of the notopodial cirri are the main differences from congeneric species.

This is the first contribution to a worldwide taxonomic revision of the closely related genera Haplosyllis (the main goal is to describe species within the Haplosyllis spongicola complex) and Geminosyllis. The type species, Haplosyllis spongicola, is re-described based on the syntypes and other material collected from Spanish seas. A combined taxon...
The spatial and temporal variations of the polychaete assemblages were studied within and off a shallow (10-25 m) tropical bay (Bahía de Portete). The polychaete abundances at family level and their trophic mechanisms were used for this purpose. Sediment samples were collected at six stations in this bay during the wet and dry seasons. Multivariate...
Durante los Cruceros INVEMAR-MACROFAUNA (1998 - 1999), realizados sobre la franja superior del talud continental del Caribe colombiano, se colectaron 26 especies de corales, de las cuales nueve son registrados por primera vez para el área. El ámbito de distribución de Polymyces fragilis y Fungiacyathus crispus se amplia hasta la costa norte de Colo...
A new species of Tethocyathus is described, T. prahli, characterized by having a tympaniform corallum shape and no fossa. Specimens were found living at 310 m in the Colombian Caribbean, 303-333 m at Cocos Island (Pacific Costa Rica), and from the early Pleistocene of Pacific Panama, suggesting a relictual distribution of a previously more widespre...
Samples of skeletons of the coral Acropora palmata obtained on the reef crest of Isla Grande, Islas del Rosario (colombian Caribbean),were found to contain two specimens of the family Alpheidae, Metalpheus rostratipes (Pocock, 1890). This shrimp species is reported for the first time from the colombian Caribbean.
