Especies de Chone Kroyer, 1856 (Polychaeta: Sabellidae) del Atlántico Oriental Central y Mar Mediterráneo
No full textA neotype specimen is designated for Chone acustica (Claparède, 1870) with a full description. The original descriptions of Chone arenicola Langerhans, 1880 and Chone collaris Langerhans, 1880, both from Madeira, did not include some details and incomplete or misleading information was provided, so both species are redescribed. Amendments to the description of Chone longiseta Giangrande, 1992 are also given together with the methyl green staining pattern of Chone usticensis Giangrande et al. 2006. Two new species are described: Chone gambiae sp. nov., from the Gulf of Naples and Chone dunerificta sp. nov., from the Gulf of Salerno. This study shows the distribution of Chone duneri Krøyer, 1856, and Chone filicaudata Southern, 1914, to be restricted to the Arctic seas and North Atlantic Ocean, respectively. Records from the Mediterranean Sea are found to be erroneous.Se designó el neotipo de Chone acustica (Claparède, 1870). Las descripciones originales de Chone arenicola Langerhans, 1880 y Chone collaris Langerhans, 1880, ambas de Madeira, no incluyen carácteres diagnósticos y la información proporcionada en otras contribuciones es incompleta, en este estudio ambas especies fueron redescritas. Se adicionaron carácteres diagnósticos a la descripción de Chone longiseta Giangrande, 1992, y se describió el patrón de tinción con verde de metilo de Chone usticensis Giangrande et al. 2006. Se describieron dos nuevas especies: Chone gambiae sp. nov., del Golfo de Nápoles y Chone dunerificta sp. nov., del Golfo de Salerno. Se restringió la distribución de Chone duneri Krøyer, 1856 para los mares del Ártico y Chone filicaudata Southern, 1914 para el Océano Atlántico Norte. Los registros de ambas especies para el Mar Mediterráneo son erróneos

Revision of Chone Kroyer, 1856 (Polychaeta : Sabellidae) from the eastern central Atlantic and Mediterranean Sea with descriptions of two new species
No full textA neotype specimen is designated for Chone acustica (Claparède, 1870) with a full description. The original
descriptions of Chone arenicola Langerhans, 1880 and Chone collaris Langerhans, 1880, both from Madeira, did not include
some details and incomplete or misleading information was provided, so both species are redescribed. Amendments to the
description of Chone longiseta Giangrande, 1992 are also given together with the methyl green staining pattern of Chone
usticensis Giangrande et al. 2006. Two new species are described: Chone gambiae sp. nov., from the Gulf of Naples and
Chone dunerificta sp. nov., from the Gulf of Salerno. This study shows the distribution of Chone duneri Krøyer, 1856, and
Chone filicaudata Southern, 1914, to be restricted to the Arctic seas and North Atlantic Ocean, respectively. Records from
the Mediterranean Sea are found to be erroneou
Polychaete zonation and its relation to algal distribution down a vertical cliff in the western Mediterranea (Italy): a structural analysis
No full textThe zonation of polychaetes down a vertical cliff (0-5 m in depth) at Cape Romito, Leghorn, Italy, was investigated. The structural organization of the community changed with depth. A community typical of photophilic environments was found in the superficial zone (0-2 m), while in the deeper zone (3-5 m), a more diversified community characterized by species typical of sciaphilic environments was present. At the surface (0 m) the community was very poor in species and individuals and thus probably corresponds to the midlittoral fringe. In fact, some species typical of the midlittoral zone were found. This distribution pattern was constant for samples taken in February and August 1985. The distribution of polychaetes was closely related to that found for macroalgae. It is hypothesized that algae condition the substratum and that this is the main factor responsible for the zonation of polychaetes. © 1988

The genus Demonax (Polychaeta, Sabellidae) in the Mediterranean Sea, with description of D. tommasi
No full textAs pointed out by Knight-Jones & Walker (1985), the
genus Demonax Kinberg has been largely ignored for the
last 100 years, due to Kinberg's (1867) diagnosis which
was a very narrow one. The genus is characterized by the
peculiar shape of companion setae (Johansson, 1925;
Rioja, 1962; Knight-Jones, 1983), while the shape of inferior
thoracic setae is very variable (Perkins, 1984).
Before considering the first of these characters, some
species with slender inferior thoracic setae were referred
to the Sabella L. genus (Banse, 1979), and species with
broadly hooded inferior thoracic setae were referred to
Potamilla Malmgren genus. For this reason, the species
Potamilla torelli Malmgren was wrongly reported within
Mediterranean fauna (Claparède, 1870; Lo Bianco, 1893;
Iroso, 1921; Giangrande, 1990).
At present 24 species are listed within the genus, of
which only D. brachychona (Claparède) and D.
tenuicollaris (Grube) are known for the Mediterranean
fauna (Knight-Jones, 1983; Knight-Jones et al., 1991).
The finding of several individuals belonging to the
genus Demonax along the Apulian coast (Adriatic Sea)
allowed a better definition of the species present in the
Mediterranean Sea, and the description of a new species
Notes on the species of Perkinsiana (Polychaeta: Sabellidae) from Antarctica with the description of P. brigittae sp. nov.
No full textNine nominal species are known from Antarctica and adjacent waters that have been assigned to the genus Perkinsiana (Polychaeta: Sabellidae). Taxonomic notes for these species are provided. Currently, only six species are considered valid: Perkinsiana antarctica (Kinberg), P. decorata (Rullier), P. borsibrunoi Giangrande and Gambi, P. magalhaensis (Kinberg), P. milae Giangrande and Gambi and P. pusilla (Johansson); P. antarctica (Gravier) is incertae sedis; P. littoralis (Hartman) is a suggested synonym of P. magalhaensis (Kinberg) and P. antarctica (Gravier), while Potamilla antarctica christenseni Augener probably belongs to the genus Notaulax. Perkinsiana is amended based on the presence of a palmate membrane and radiolar flanges, and three types of abdominal chaetae. The new species Perkinsiana brigittae sp. nov. is here described from collections taken by the U. S. Antarctic Research Program (USARP) at Wilkes Station. A taxonomic key for species of Perkinsiana from Antarctica is provided
Z Andromedae
No full textZ ANDROMEDAE G. Baratta, Rome Observatory; A. Altamore, Rome University; A. Cassatella, European Space Agency, Madrid; and A. Giangrande, O. Ricciardi and R. Viotti, Laboratorio di Astrofisica Spaziale, Frascati, report that new ultraviolet spectra of Z And obtained with the International Ultraviolet Explorer on Feb. 17 showed no significant change in the emission lines. The minimum electron density in the emitting region was 10**9 cm**-3. The optical spectrum, obtained at Campo Imperatore, and the luminosity are still those of the quiescent phase
El género Branchiomma (Polychaeta: Sabellidae) en el Mediterráneo, con la descripción de B. maerli n. sp.
No full textThe genus Branchiomma (Annelida: Polychaeta: Sabellinae) from the Mediterranean Sea is revised based on material collected during several surveys and preserved in the Zoological Laboratory of Lecce University (South Italy). Branchiomma maerli n. sp. is described as a new species and compared with the previously reported B. bombyx, B. lucullanum, B. luctuosum, and B. cf. moebii. Branchiomma maerli n. sp. resembles B. lucullanum, but differs in the shape of the collar and in the length of the dorsal lips. Branchiomma boholensis, reported as the only Mediterranean species with macrostylodes, is not here described because it has not been possible to obtain adequate material. Finally, Branchiomma sp. (similar to B. violaceum, but having the dorsal collar fused to the faecal groove) is not formally described as a new species because there is only one available specimen.En este trabajo se revisa el género Branchiomma (Annelida: Polychaeta: Sabellinae) del mar Mediterráneo a partir de material recolectado durante varias campañas y conservado en el Laboratorio Zoológico de la Universidad de Lecce (sur de Italia). Branchiomma maerli n. sp. se describe como una nueva especie y se compara con especies previamente reportadas B. bombyx, B. lucullanum, B. luctuosum y B. cf. moebii. Branchiomma maerli n. sp. se parece a B. lucullanum, pero difiere en la forma del collar y en la longitud de los labios dorsales. Branchiomma boholensis, reportada como la única especie Mediterránea con macroestilodes, no se describe aquí ya que no fue posible obtener material adecuado. Finalmente, Branchiomma sp. (parecida a B. violaceum, aunque con el collar dorsal fusionado al surco fecal) no se describe formalmente como nueva especie porque sólo se dispone de un único ejemplar
