A new genus, a new species, and a new record of the family Darcythompsoniidae Lang, 1936 (Gopepoda, Harpacticoida) from the Gulf of California, Mexico

A new genus and new species of the family Darcythompsoniidae Lang (1936), and a new record of Darcythompsonia fairliensis (T. Scott, 1899), from a coastal lagoon in the south-eastern Gulf of California (Mexico), are reported and fully described and illustrated. Pabellonia olganoguerae gen. no v., sp.nov. shares features with Darcythompsonia T. Scott, 1906, such as the presence of a dimorphic second endopodal segment of the male second swimming leg, and with Kristensenia Por, 1983, the lack of sexual dimorphism in the caudal rami, anal operculum and urosomites. Thus it is considered closely related to these genera, and to represent a third component of mis lineage. Some notes on the biogeography of Darcythompsonia T. Scott, 1906, are also presented.

A revision of the genus Halectinosoma (Harpacticoida: Ectinosomatidae): a reappraisal of H. sarsi (Boeck) and related species

Ectinosomatid material was examined from extensive collections around the British Isles and from several additional world localities and museum collections, permitting a revision of the genus Halectinosoma. This paper describes 12 morphologically similar species and erects five new species. H. sarsi (Boeck) is regarded as species incertae sedis, while H. sarsi sensu Sars (1904) is redescribed as H. pseudosarsi sp. nov.; H. sarsi sensu T. & A. Scott (1894) is synonymized with H. canaliculatum (Por). H. propinquum is regarded as a junior subjective synonym of H. chrystalli (T. Scott). H. clavatum (Sars) is resurrected, having previously been regarded as a synonym of H. brunneum (Brady). A key for the identification of females belonging to this group of species is provided.     

Loxocorone,a new genus of the family loxosomatidae (Entoprocta: Solitaria), with descriptions of two new Loxomitra (sensu stricto) and a new Loxocorone from Okinawa,the Ryukyu Archipelago,Japan

The type species of Loxomitra Nielsen, 1964, L. kefersteinii (Claparède, 1867), has following characters: A) the buds have a pair of terminal wings at the base of the stalk, and B) the liberated buds crawl on the substratum by attaching the two terminal wings to the substratum and twisting the whole body. By contrast, some other members of the genus have following characters: A') the buds lack the terminal wings but have a foot with foot groove, and B') the liberated buds glide over the substratum using the foot with foot groove. I thus propose to divide Loxomitra (sensu lato) into two genera- Loxomitra (sensu stricto) characterized by A) and B), and Loxocorone gen. nov. by A') and B'). I also describe two new Loxomitra (sensu stricto), L. mizugamaensis sp. nov., and L. tetraorganon sp. nov., and one new Loxocorone, L. allax sp. nov. from the Ryukyu Archipelago, Japan. All of the currently recognized species of the Loxomitra (sensu lato) are reviewed to specify their generic allocations in response to the above change.

Studies on the Cylindropsyllidae (Copepoda, Harpacticoida). 1. The status of Leptastacus laticaudatus Nicholls

Leptastacus laticaudatus Nicholls, 1935, commonly found interstitially in fine sands of European boreal waters, is redescribed and figured. As a result, the subspecies names L. laticaudatus laticaudatus and L. laticaudatus intermedius Kunz, 1938 are nullified. Some variable characters, i.e. caudal rami and structure of the fifth leg, are discussed and the distribution of the species is summarized. The most closely allied species L. macronyx (T. Scott, 1892) and L. spatuliseta Mielke, 1982 constitute, together with L. laticaudatus , the 'macronyx -group'. L. laticaudatus intermedius sensu Apostolov, 1973 is considered species inquirenda . An amended diagnosis of the genus Leptastacus T. Scott, 1906 is presented.

Five new species of Urocleidoides (Monogenoidea) (Mizelle and Price 1964) Kritsky, Thatcher, and Boeger, 1986, parasitizing the gills of Panamanian freshwater fishes

During an investigation of gill monogenoidean parasites from freshwater fishes in central Panama, 5 new species of Urocleidoides (sensu stricto) were found: Urocleidoides cultellus n. sp., Urocleidoides visiofortatus n. sp., and Urocleidoides advenai n. sp. from the gymnotiform Brachyhypopomus occidentalis (Hypopomidae); Urocleidoides neotropicalis n. sp. and Urocleidoides piriatiu n. sp. from the characiforms Saccodon dariensis (Parodontidae) and Ctenolucius beani (Ctenoluciidae), respectively. Our findings represent the first known species of Urocleidoides from these fishes in Central America and demonstrate that they are morphologically linked to their South American congeners.     

Biogeography of helminth parasitism in Lemmus Link (Arvicolinae), with the description of Paranoplocephala fellmani n. sp. (Cestoda: Anoplocephalidae) from the Norwegian lemming L. lemmus (Linnaeus)

We describe the gastrointestinal helminth fauna of true lemmings (Lemmus spp., Arvicolinae) based on published and original material throughout the Holarctic range of these hosts. According to the existing data, the helminth fauna of true lemmings consists of three widespread and/or locally common taxa: Hymenolepis horrida (sensu lato) (Hymenolepididae), Anoplocephaloides lemmi (Anoplocephalidae) and Heligmosomoides spp. (Heligmosomidae). Despite the taxonomic boundaries and ancient phylogenetic splits in the hosts, there are no major faunistic differences for parasites within western (Siberian) L. sibiricus and L. bungei, and eastern (North American) L. trimucronatus throughout their distribution range. In contrast, the Norwegian lemming L. lemmus, which is a Fennoscandian endemic and closely related to the western populations of L. sibiricus, has only a single host-specific helminth, the cestode Paranoplocephala fellmani n. sp. (Anoplocephalidae). We describe the new species and show that it differs consistently from related species by its long and slender cirrus-sac. However, there are also a number of other significant differences, e.g., P. fellmani n. sp. and Andrya primordialis in Tamiasciurus hudsonicus (Sciuridae) evidently have a unique (sub)type of uterine development among Andrya/Paranoplocephala spp. Because P. fellmani n. sp. was also found to occur in Alaska (host L. trimucronatus), this species seems to follow the same biogeographical pattern as the other specialist helminths of Lemmus. We suggest alternative explanations for the absence of three major helminth taxa in the Norwegian lemming in Fennoscandia.

Morphology and phylogeny of a new urostylid ciliate, Monocoronella carnea n. g., n. sp. (Ciliophora, Hypotricha) from Daya Bay, Southern China

The morphology, infraciliature and small subunit ribosomal RNA gene-based phylogeny of an urostylid ciliate, Monocoronella carnea n. g., n. sp., found in coastal areas off Daya Bay, Southern China, were investigated. The new genus Monocoronella n. g. is recognized by the following features: having conspicuous frontal cirri forming a long and single corona; buccal and frontoterminal cirri present; single marginal row on each side; adoral zone, midventral complex and transverse cirri in Pseudokeronopsis mode. The type species M. carnea n. sp. is diagnosed by the combination of marine habitat and brown-reddish color of the cortical granules. Phylogenetic analyses for the new taxon indicate that Monocoronella n. g. is most closely related to Bergeriella, and is located within the core Urostylida clade. A misidentification in previous literature was recognized and a new species, Monocoronella dragescoi n. sp. [Basionym: Holosticha (Keronopsis) monilata (Kahl 1928) sensu Dragesco (1970) et sensu Dragesco and Dragesco-Kernéis (1986), non sensu Kahl (1928)], was suggested.

Three New Species of Minoninae (Turbellaria, Proseriata, Monocelididae) from the North Sea, with Remarks on the Taxonomy of the Subfamily

Three new species of Minoninae are described and a new genus is proposed for one of them: Minona degadti sp.n., Duplominona septentrionalis sp.n. and Duploperaclistus circocirrus gen. et sp.n. All three species occur in sublittoral sandy habitats in the Southern Bight of the North Sea, but D. circocirrus has also been found at a littoral station. The taxonomy within the subfamily Minoninae is discussed. Seven genera are considered as valid, and they are briefly diagnosed. " Peraclistus ituipus" sensu Westblad (1952) (= Duplominona westbladi Karling, 1966) is included in the new genus as Duploperuclistus westbladi (Karling, 1966) comb.n.     

Monogeneans from Pangasiidae (Siluriformes) in Southeast Asia: III. Five new species of Thaparocleidus Jain, 1952 (Ancylodiscoididae) from Pangasius bocourti,P. djambal and P. hypophthalmus

The examination of gill parasites from Pangasius bocourti Sauvage, 1880; P. djambal Bleeker, 1846; P. hypophthalmus (Sauvage, 1878) and P. gigas Chevey, 1930 (Siluriformes, Pangasiidae) revealed the presence of seven species of Monogenea among which five are considered new species. They all belong to Thaparocleidus Jain, 1952 (Ancylodiscoididae) as defined by Lim (1996) and Lim et al. (2001). P. bocourti: T. combesi n. sp., T. komarudini n. sp. and T. vietnamensis n. sp. P. djambal: T. caecus (Mizelle & Kritsky, 1969), T. combesi n. sp., T. euzeti n. sp., T. komarudini n. sp. and T. sadilii n. sp. P. hypophthalmus: T. caecus, T. siamensis (Lim, 1990) and T. vietnamensis n. sp. P. gigas: no Monogenea were found on this host species.
