Faunal studies on testate amoebae from Korea have been Phylum Amoebozoa Lühe, 1913 performed by several researchers (Chung and Choi 1989, Subphylum Lobosa Carpenter, 1861 1995; Chung and Cha 1990; Chung and Kang 1991; Chung Class Tubulinea Smirnov et al., 2005 et al. 1992). As a result, thirty­three species of freshwater Order Arcellinida Kent, 1880 testate amoebae have been reported in this country. But many Family Arcellidae Ehrenberg, 1843 species are still remaining to be discovered.

Testate amoebae in Vietnam are still poorly investigated. We studied species composition of testate amoebae in 47 waterbodies of South Vietnam provinces including natural lakes, reservoirs, wetlands, rivers, and irrigation channels. A total of 109 species and subspe- cies belonging to 16 genera, 9 families were identified from 191 samples. Thirty-five species and subspecies were observed in Vietnam for the first time. New speciesDifflugia vietnamica sp. nov. is described. The most species-rich genera are Difflugia (46 taxa), Arcella (25) and Centropyxis (14). Centropyxis aculeata was the most common species (observed in 68.1% samples). Centropyxis aerophila sphagniсola, Arcella discoides, Difflugia schurmanni and Lesquereusia modesta were characterised by a frequency of occurrence >20%. Other spe- cies were rarer. The species accumulation curve based on the entire dataset of this work was unsaturated and well fitted by equation S = 19.46N0.33. Species richness per sample in natural lakes and wetlands were significantly higher than that of rivers (p < 0.001). The result of the Spearman rank test shows weak or statistically insignificant relationships between species richness and water temperature, pH, dissolved oxygen, and electrical conductivity.

Approxi- mately 25 O/O mortality was observed in the net pens in 1985, and the disease recurred in 1986 and 1987. Amoeba infesting the gill surfaces elicited prominent epithelia1 hyperplasia. Typical of Paramoeba spp., the parasite had a Feulgen positive parasome (Nebenkorper) adjacent to the nucleus and floatlng and transitional forms had digitiform pseudopodia. We have established cultures of the organism from coho gills; it grows rapidly on Malt-yeast extract sea water medium supplemented with Klebsiella bacteria. Ultrastructural characteristics and nuclear, parasome and overall size of the organism in study indicated it is most closely related to the free-living paramoeba P. pemaquidensis. The plasmalemma of the amoeba from coho gills has surface filaments. Measurements (in pm) of the amoeba under various conditions are as follows: transitional forms directly from gills 28 (24 to 30),locomotive forms from liquid culture 21 X 17 (15 to 35 X 11 to 25), and locomotive forms from agar culture 25 X 20 (15 to 38 X 15 to 25).

    Conicocassis, a New Genus of Arcellinina (Testate Lobose Amoebae)

    Palaeontologia Electronica palaeo-electronica.org Conicocassis, a new genus of Arcellinina (testate lobose amoebae) Nawaf A. Nasser and R. Timothy Patterson ABSTRACT Superfamily Arcellinina (informally known as thecamoebians or testate lobose amoebae) are a group of shelled benthic protists common in most Quaternary lacus- trine sediments. They are found worldwide, from the equator to the poles, living in a variety of fresh to brackish aquatic and terrestrial habitats. More than 130 arcellininid species and strains are ascribed to the genus Centropyxis Stein, 1857 within the family Centropyxidae Jung, 1942, which includes species that are distinguished by having a dorsoventral-oriented and flattened beret-like test (shell). Conicocassis, a new arcel- lininid genus of Centropyxidae differs from other genera of the family, specifically genus Centropyxis and its type species C. aculeata (Ehrenberg, 1932), by having a unique test comprised of two distinct components; a generally ovoid to subspherical, dorsoventral-oriented test body, with a pronounced asymmetrically positioned, funnel- like flange extending from a small circular aperture. The type species of the new genus, Conicocassis pontigulasiformis (Beyens et al., 1986) has previously been reported from peatlands in Germany, the Netherlands and Austria, as well as very wet mosses and aquatic environments in High Arctic regions of Europe and North America. The occurrence of the species in lacustrine environments in the central Northwest Ter- ritories extends the known geographic distribution of the genus in North America con- siderably southward.

Leander Canadian Institute for Advanced Research, Program in Evolutionary Biology, Departments of Botany and Zoology, University of British Columbia, Vancouver, BC, Canada, V6T 1Z4 Submitted November 30, 2005; Accepted March 4, 2006 Monitoring Editor: Herve´ Philippe Ebria tripartita is a phagotrophic flagellate present in marine coastal plankton communities worldwide. This is one of two (possibly four) described extant species in the Ebridea, an enigmatic group of eukaryotes with an unclear phylogenetic position. Ebriids have never been cultured, are usually encountered in low abundance and have a peculiar combination of ultrastructural characters including a large nucleus with permanently condensed chromosomes and an internal skeleton composed of siliceous rods. Consequently, the taxonomic history of the group has been tumultuous and has included a variety of affiliations, such as silicoflagellates, dinoflagellates, ‘radiolarians’ and ‘neomonads’. Today, the Ebridea is treated as a eukaryotic taxon incertae sedis because no morphological or molecular features have been recognized that definitively relate ebriids with any other eukaryotic lineage. We conducted phylogenetic analyses of small subunit rDNA sequences from two multi-specimen isolations of Ebria tripartita. The closest relatives to the sequences from Ebria tripartita are environmental sequences from a submarine caldera floor. This newly recognized Ebria clade was most closely related to sequences from described species of Cryothecomonas and Protaspis. These molecular phylogenetic relationships were consistent with current ultrastructural data from all three genera, leading to a robust placement of ebriids within the Cercozoa.

Phylogenetic analyses revealed that 2 of 5 morphologically indistinguishable strains clustered with 6 strains identified previously as N. pemaquidensis (Page, 1970). Three strains branched as a clade separated from N. pemaquidenis and N. aestuarina (Page, 1970) clades. Our analyses suggest that these 3 strains could be representatives of an independent species. In a more comprehensive eukaryotic tree, strains belonging to Neoparamoeba spp. formed a monophyletic group with a sister-group relationship to Vannella anglica Page, 1980. They did not cluster with Gymnamoebae of the families Hartmannellidae, Flabellulidae, Leptomyxidae or Amoebidae presently available in GenBank.
