The importance of identifying biological diversity accurately and efficiently is becoming more evident. It is therefore critical to determine the species boundaries between closely related taxa and to establish diagnostic characters that allow us to define species. This is not an easy task when species exhibit high intraspecific phenotypic plasticity or when distinct evolutionary lineages with an unusually large amount of genetic distinctiveness show no apparent morphological diversity (cryptic species). These phenomena appear to be common in the genus of fan worms Branchiomma (Sabellidae, Annelida) and consequently taxonomic errors are widespread in the group. Moreover, some Branchiomma species have been unintentionally translocated outside the area where natural range extension is expected, increasing the taxonomic problems. We have performed a range of analytical methods including genetic distances, Bayesian Interference, maximum likelihood, maximum parsimony, statistical parsimony analyses and general mixed Yule coalescent model to clarify the taxonomic status and asses the species boundaries of Branchiomma in Australia. This study shows that the traditional diagnostic morphological features are greatly homoplastic. Results also indicate that the diversity of Branchiomma in Australia is Capa 2 higher than previously reported and evidence some cases of high phenetic plasticity (in features previously considered as stable within species), high intraspecific genetic variability, cryptic species and several unexpected cases of translocations.

Joan Pons, IMEDEA (CSIC-UIB), Instituto Mediterráneo de Estudios Capa 3 IntroductionThe genus Branchiomma is a homogeneous group of fan worms (Sabellidae, Annelida) characterised by the presence of paired compound eyes and stylodes alternating along the radioles ( Figs 1A-B, 2). The stylodes are epithelial appendages directed outwards of the radiolar crown, unique amongst members of Sabellidae and their shape and relative length between the radioles (Fig. 1A-G) is considered to be one of the main specific diagnostic features (Knight-Jones, 1994;Tovar-Hernández & Knight-Jones, 2006). There are currently around 30 nominal species of Branchiomma (Tovar-Hernández & Dean, 2010) described from a variety of shallow water environments, ranging from fine sediments to hard substrates and from many localities around the world. Some of these nominal species are well defined morphologically with precise data about their reproductive strategies, ecology and geographic distribution being available (e.g. Sordino & Gambi, 1992;Licciano et al., 2002;Tovar-Hernández & Knight-Jones, 2006;Licciano & Giangrande, 2008; TovarHernán...

“…The Sabellidae Latreille, 1825 inhabit all seas, both in hard and soft substrates, from intertidal to abyssal depths, including coral reefs, but are also found in fresh waters (Fitzhugh, 1989;Rouse, Pleijel, 2001). The family comprised about 490 species, with more than 70 belonging to the Fabriciinae, and over 400 to Sabellinae (Rouse, Pleijel, 2001;Tovar-Hernández, Dean, 2010). All sabellids (including Chone Krøyer, 1856 and the closely related genera Amphicorina Claparede, 1864, Euchone Malmgren, 1866, andJasmineira Langerhans, 1880) are suspension feeders, while some small forms may also be deposit feeders.…”

A new species of Dialychone, D. egyptica sp.n. (Sabellidae) is described from the Mediterranean Coast of Egypt. The material was collected from soft bottom at 60 m depth. It is unique among the genus in having an abdominal glandular ridge on chaetiger 13. The new species is also characterized by having pygidial cirrus, medium sized radiolar tips and long radiolar pinnules, anterior peristomial ring lobe incised and exposed beyond collar, a trapezoidal ventral collar shield, and paleate chaetae with long mucro. The distributions of Dialychone collaris (Langerhans, 1880), D. usticensis (Giangrande et al., 2006), D. dunerificta (Tovar-Hernández et al., 2007), and Paradialychone gambiae (Tovar-Hernández et al., 2007) along the Mediterranean coast of Egypt are also presented. P. gambiae reported for the first time in the Egyptian coasts, while D. dunerificta was previously recorded as Chone duneri Malmgren,

Isla del Coco, Pacífico de Costa Rica, ha sido visitada y se ha escrito sobre ella desde el Siglo xvI. Desde finales del Siglo xIx muchas expediciones han desarrollado investigaciones en el Isla. Aquí compilo las publicaciones sobre biología y geología marina, oceanografía física y química, ciencias atmosféricas y algunos temas sociales. Una lista de 599 artículos y capítulos, 41 libros, Suplementos, tesis, informes y un sitio de internet es incluida, y diez libros históricos donde se describen organismos y ambientes marinos de la Isla del Coco. La mayoría de las publicaciones (425 o 66.4%) son sobre biodiversidad marina (descripciones, listas y distribuciones de especies). De los grupos que más publicaciones hay son de los gasterópodos (81 trabajos), decápodos (67) y peces óseos (66). No hay publicaciones de varios grupos de animales que han sido observados en Isla del Coco, por ejemplo, gusanos planos de vida libre, parásitos o nemertinos, entre otros. Temas con muchas publicaciones son: biogeografía con 65, ecología (61) y geología (48); los ecosistemas más estudiados son los arrecifes coralinos con 14 trabajos. Se necesitan más publicaciones en muchos tópicos, tales como el impacto sobre la flora y fauna del Parque Nacional Isla del Coco de la pesca ilegal y el cambio climático.
