  • Nanoplankton protists from the western Mediterranean Sea. II. Cryptomonads (Cryptophyceae = Crptomonadea)
    Scientia Marina, 2005
    Co-Authors: Gianfranco Novarino
    Abstract:

    This paper is an electron microscopical account of cryptomonad flagellates (Cryptophyceae = Cryptomonadea) in the plankton of the western Mediterranean Sea. Bottle samples collected during the spring-summer of 1998 in the Sea of Alboran and Barcelona coastal waters contained a total of eleven photosynthetic species: Chroomonas (sensu auctorum) sp., Cryptochloris sp., 3 species of Hemiselmis , 3 species of Plagioselmis including Plagioselmis nordica stat. nov/sp. nov., Rhinomonas reticulata (Lucas) Novarino, Teleaulax acuta (Butcher) Hill, and Teleaulax amphioxeia (Conrad) Hill. Identification was based largely on cell surface features, as revealed by scanning electron microscopy (SEM). Cells were either dispersed in the water-column or associated with suspended particulate matter (SPM). Plagioselmis prolonga was the most common species both in the water-column and in association with SPM, suggesting that it might be a key primary producer of carbon. Taxonomic Keys are given based on SEM.

  • Two new apseudomorphan species (Crustacea: Tanaidacea: Metapseudidae) from Mo‘orea Island (Society Islands, French Polynesia) with Taxonomic Keys
    Zootaxa, 2019
    Co-Authors: Andrés G. Morales-núñez, Richard W. Heard, Graham J. Bird
    Abstract:

    Previous information on the taxonomy and distribution of the crustacean order Tanaidacea occurring within the widely-dispersed Polynesian Archipelago has been limited to four nominal species, Apseudes rikiteanus Nobili, Apseudes seurati Nobili, Zeuxo seurati (Nobili) and Tanzanapseudes polynesiensis Muller. Based on specimens collected between 2009 and 2011 from coastal waters of Mo‘orea Island (Society Islands, French Polynesia), two new metapseudid tanaidaceans, Apseudomorpha drumm i and Cryptapseudes mamua, are described. Keys to the identification of species currently placed within the genera Apseudomorpha Guţu and Cryptapseudes Băcescu are provided.

  • two new paratanaid tanaidacea crustacea malacostraca peracarida from the hawaiian islands with illustrated Taxonomic Keys
    Zootaxa, 2016
    Co-Authors: Andres G Moralesnunez, Sara Pelleteri, Richard W. Heard
    Abstract:

    Two new tanaidomorphan tanaidaceans, Aparatanais hawaiensis , sp. nov. and Metatanais spinipropodus, sp. nov. represent the first members of the Family Paratanaidae to be described from the Hawaiian Islands. Aparatanais hawaiensis is distinguished from the other species of the genus by the setation of the antenna, maxilliped, chela, and pereopods. Metatanais spinipropodus is distinguished from the other three members of its genus by its chela having a strongly developed, chisel-like, spiniform seta on the inner face of propodus near the sub-distal margin of the fixed finger. The Hawaiian occurrence of M. spinipropodus extends the range for the genus Metatanais well-eastward into the mid-Pacific Ocean. This study presents the first description of a male attributable to the genus Aparatanais .
