Deep-Sea Cymothoid Isopods (Crustacea: Isopoda: Cymothoidae) of Pacifi C Coast of Northern Honshu, Japan
Deep-sea Fauna and Pollutants off Pacifi c Coast of Northern Japan, edited by T. Fujita, National Museum of Nature and Science Monographs, No. 39, pp. 467-481, 2009 Deep-sea Cymothoid Isopods (Crustacea: Isopoda: Cymothoidae) of Pacifi c Coast of Northern Honshu, Japan Takeo Yamauchi Toyama Institute of Health, 17̶1 Nakataikoyama, Imizu, Toyama, 939̶0363 Japan E-mail: [email protected] Abstract: During the project “Research on Deep-sea Fauna and Pollutants off Pacifi c Coast of Northern Ja- pan”, a small collection of cymothoid isopods was obtained at depths ranging from 150 to 908 m. Four species of cymothoid isopods including a new species are reported. Mothocya komatsui sp. nov. is distinguished from its congeners by the elongate body shape and the heavily twisting of the body. Three species, Ceratothoa oxyrrhynchaena Koelbel, 1878, Elthusa sacciger (Richardson, 1909), and Pleopodias diaphus Avdeev, 1975 were fully redescribed. Ceratothoa oxyrrhynchaena and E. sacciger were fi rstly collected from blackthroat seaperchs Doederleinia berycoides (Hilgendorf) and Kaup’s arrowtooth eels Synaphobranchus kaupii John- son, respectively. Key words: Ceratothoa oxyrrhynchaena, Elthusa sacciger, Mothocya, new host record, new species, Pleo- podias diaphus, redescription. Introduction Cymothoid isopods are ectoparasites of marine, fresh, and brackish water fi sh. In Japan, about 45 species of cymothoid isopods are known (Saito et al., 2000), but deep-sea species have not been well studied. This paper deals with a collection of cymothoid isopods from the project “Research on Deep-sea Fauna and Pollutants off Pacifi c Coast of Northern Japan” conducted by the National Museum of Nature and Science, Tokyo. -

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -

Two distinct classes of myxozoans, Myxosporea and Malacosporea, are characterized by profound differences in rDNA evolution and well supported by differential biological and developmental features. This notwithstanding, most of the existing Myxosporea subtaxa require revision in the light of molecular phylogeny data.

Fish samples were collected together with water quality parameters from eight Meghna estuary sampling stations of the Meghna river estuary from November 2011 to April 2012. Fifty years mete- orological data were collected from meteorological department. Diversity status were analyzed from all fisheries data by using PAST (version 2.15) software.

Marine Fishes of the Azores: an Annotated Checklist and Bibliography
MARINE FISHES OF THE AZORES: AN ANNOTATED CHECKLIST AND BIBLIOGRAPHY. RICARDO SERRÃO SANTOS, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS SANTOS, RICARDO SERRÃO, FILIPE MORA PORTEIRO & JOÃO PEDRO BARREIROS 1997. Marine fishes of the Azores: An annotated checklist and bibliography. Arquipélago. Life and Marine Sciences Supplement 1: xxiii + 242pp. Ponta Delgada. ISSN 0873-4704. ISBN 972-9340-92-7. A list of the marine fishes of the Azores is presented. The list is based on a review of the literature combined with an examination of selected specimens available from collections of Azorean fishes deposited in museums, including the collection of fish at the Department of Oceanography and Fisheries of the University of the Azores (Horta). Personal information collected over several years is also incorporated. The geographic area considered is the Economic Exclusive Zone of the Azores. The list is organised in Classes, Orders and Families according to Nelson (1994). The scientific names are, for the most part, those used in Fishes of the North-eastern Atlantic and the Mediterranean (FNAM) (Whitehead et al. 1989), and they are organised in alphabetical order within the families. Clofnam numbers (see Hureau & Monod 1979) are included for reference. Information is given if the species is not cited for the Azores in FNAM. Whenever available, vernacular names are presented, both in Portuguese (Azorean names) and in English. Synonyms, misspellings and misidentifications found in the literature in reference to the occurrence of species in the Azores are also quoted. The 460 species listed, belong to 142 families; 12 species are cited for the first time for the Azores. -
