Flabelliderma cinari (Polychaeta: Flabelligeridae), a new species from the Eastern Mediterranean

A new species of flabelligerid polychaete, Flabelliderma cinari, is described from the Turkish coast of the Eastern MediterraneanSea. This represents the first occurrence of the genus Flabelliderma in the Mediterranean. Flabelliderma cinari sp. nov. isclosely allied to F. claparedei in having dorsal tubercles of two different sizes; however, these species differ in the relative shapeand number of dorsal tubercles, the number of capillaries per fascicle in the notopodia and the shape of the curved distal articlesin the neuropodial hooks

Redescription Of Eunice Sebastiani And Recognition Of E. Riojai (polychaeta: Eunicidae)

In a series of studies on eunicids, there were explicit or implicit indications that Eunice riojai described from the north-western Caribbean Sea, and Eunice sebastiani described from south-east Brazil, were synonyms. This was based upon a then recent monograph on the genus, and on the fact that some specimens were found in drifting wood which would explain the large geographical range. The study of some large specimens of E. sebastiani, collected at the type locality, shows that there are several relevant morphological differences between the two species and thus both species names must be regarded as distinct. In fact, E. sebastiani is unique in the genus because their maxillae V are bidentate. Furthermore, herein we re-describe these two species and re-evaluate some morphological features described in previous studies. © 2008 Marine Biological Association in the United Kingdom.88350350

Nuevos registros y extensiones de ámbito de poliquetos (Annelida:Polychaeta), de México

En este trabajo se registran 17 especies de anélidos poliquetos por primera vez para México, 10 Syllidae, dos Spionidae, dos Sabellidae y un Nereidae, Eunicidae y Terebellidae. Las extensiones de ámbito van desde 500 hasta 3,500 km Ehlersia cornuta. (Syllidae) y Manchiomma nígtomaculata (Sabellidae) se reportan por primera vez para el Océano Pacifico Oriental. Estos nuevos registros y extensiones de ámbito son el producto de la intensificación del esfuerzo de investigación en ecología bentónica en aguas mexicana
