Aceptado 04-XI-2014. Abstract: Taxonomy and ecologic biogeography of the irregular Echinoids (Echinoidea: Irregularia) from Mexico. Mexico owns 643 species of echinoderms, almost 10% of the known echinoderm species in the planet. Its geographic location -between the oceanic influences of the Western Central Atlantic and the Eastern Central Pacific- largely explains its enormous biological and ecological diversity. Research on echinoderms in Mexico began in the late nineteenth century; however, there are no reviews on its irregular echinoids. This work reviews the taxonomic and geographic information of irregular echinoids from Mexico, housed in four collections: 1) Colección Nacional de Equinodermos “Ma. Elena Caso Muñoz” from the Instituto de Ciencias del Mar y Limnología (ICML), Universidad Nacional Autónoma de México (UNAM); 2) Invertebrate Zoology Collection, Smithsonian Museum of Natural History, Washington, D.C., United States of America (USA); 3) Invertebrate Collection, Museum of Comparative Zoology, University of Harvard, Boston, Massachusetts, USA and 4) Invertebrate Zoology, Peabody Museum, Yale University, New Haven, Connecticut, USA. -
Onetouch 4.0 Sanned Documents
Vol. 82, pp. 1-30 29 May, 1969 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON REVIEW OF SOME SPECIES REFERRED TO SCALISETOSUS MCINTOSH (POLYCHAETA, POLYNOIDAE) BY MABIAN H. PETTIBONE Smithsonian Institution, Washington, D. C. In connection with an extended review of the polynoid gen- era, based on a study of the type-species, it was foimd that Scalisetosus Mclntosh ( 1885) has been used for a heterogenous group of species. The genus has served to include species with setae as transparent as crystal and the neurosetae character- ized by the presence of a basal semilunar cusp or pocket, al- though this particular feature was not shown on the figure of the neiu-osetae of the type-species, S. ceramensis, by Mclntosh (1885, pi. lOA, fig. 14). Any species equipped with this pe- culiar type of neiu-osetae has been placed in Scalisetosus, re- gardless of other characters. Saint-Joseph (1899) proposed the new genus Adyte for three species {Polynoe pellucida Ehlers, Hermadion assimile Mclntosh, and H. echini Giard) having the peculiar type of neurosetae, separating them from S. cera- mensis, which lacks the basal semilunar cusps. Mclntosh (1900) was responsible for changing the diagnosis of Scali- setosus to include the species referred to Adyte by Saint- Joseph, Subsequently, Adyte was abandoned and was synony- mized with Scalisetosus by Fauvel (1914, p. 47). During a visit to the British Museum of Natural History in May 1967, I was able to examine the unique type of Scalise- tosus ceramensis and to verify that the neurosetae indeed do lack the basal semilunar cusps and that the species therefore lacks one of the key characters that has been attributed to the genus. -
(Polychaeta) from the CANARY ISLANDS
BULLETIN OF MARINE SCIENCE, 48(2): l8D-188, 1991 POL YNOIDAE (pOLYCHAETA) FROM THE CANARY ISLANDS M. C. Brito, J. Nunez and J. J. Bacallado ABSTRACT This paper is a contribution to the study of the family Polynoidae (Polychaeta) from the Canary Islands. The material examined has been collected by the authors from 1975 to 1989. A total of 18 species was found belonging to 8 genera: Gesiel/a (I), Po/ynoe (1), Adyte (I), Subadyte (I), Harrnothoe (11), A/entia (1), Lepidasthenia (1) and Lepidonotus (I). Ten species are new to this fauna and one, Harrnothoe cascabullico/a, is new to science. Furthermore, the genera Po/ynoe, Adyte and Lepidasthenia are recorded for the first time in the Canary Islands. The Polychaeta of the Canary Islands are enumerated in the provisional cata- logue of Nunez et al. (1984), in which are recorded 148 species, 12 of which belong to the family Polynoidae. Samples from the Canary coastline were examined and members ofPolynoidae studied. A total of 173 specimens was studied, belonging to 7 subfamilies, 8 genera, and 18 species, of which 9 species are recorded for the first time in the Canarian fauna. Worthy of note is the large number of species belonging to the genus Harmothoe (11), one of which, H. cascabullicola is new. METHODS The material examined was collected from 1975 to 1989, from 61 stations, at 45 localities on the Canary coasts (Fig. I). The list of stations, with their localities, types of substrate and collecting data are listed in Table I. The methods used in collecting depended on the type of substrate. -

Early descriptions of species from Norwegian waters are reviewed, with a focus on the basic requirements for re- assessing their characteristics, in particular, by clarifying the status of the original material and locating sampling sites.
