| Recent collections in the south central U.S.A. have included three neotropical and one probably introduced species that are presently assigned to the cyclopoid copepod genus Mesocyclops. Mesocyclops longisetus var. curvatus Dussart, 1987, is reported from Louisiana, U.S.A., and Panama; published records of Mesocyclops longisetus (Thiébaud, 1914) sensu lato in the southern U.S.A. are reviewed. Mesocyclops reidae Petkovski, 1986, is reported from Mississippi, U.S.A., and Honduras. Mesocyclops ruttneri Kiefer, 1981, is redescribed from type specimens collected in Austria, and newly reported from Louisiana, Mississippi, China, Thailand, and Viet Nam. This species is considered to have been introduced from Asia into Austria and the U.S.A. Mesocyclops bernardi... |

| The zooplankton of an eutrophic brackish lagoon (Etang de Berre), near Marseille (France) was studied during an annual cycle. It was characterized by large populations of a pelagic copepod (Acartia tonsa ). Grazing on natural particles by this species was investigated. Adults were able to use an extended range of particle sizes, but showed selectivity for particles concentration was observed (14 mu m). Temperature and particles concentration appear to modify the selectivity behavior. Juvenile stages could also catch particles of various size but did not show the same selectivity for the peak particles as adults. Daily food ration was high comparatively to open-sea copepods. Taking into account several results obtained on food ration, egg production and... |

| Reidcyclops n. gen. (Copepoda, Cyclopoida) is established to comprise three species, previously considered as members of the genus Diacyclops: Reidcyclops dimorphus (Reid & Strayer, 1994) n. comb., R. imparilis (Monchenko, 1985) n. comb., and R. trajani (Reid & Strayer, 1994) n. comb. (here designated as the type species). This genus is characterised by a 2-segmented fifth leg, and by the presence of sexual dimorphism in the swimming legs, as well as by other characteristics. In this paper the male of R. trajani is described for the first time from Macedonia. The taxonomic position of the new genus within the subfamily Cyclopinae is discussed. |

| A survey of the groundwater fauna of The Netherlands has revealed the presence of 4 species of Parastenocarididae, viz. Parastenocaris fontinalis Schnitter & Chappuis, 1915, P. tumida Kiefer, 1961, P. germanica Kiefer, 1936, and P. nolli Kiefer, 1938, the latter two being new for The Netherlands. P. tumida is only imperfectly known, but there is enough material so that a full description can now be given not only of the female but also of the male hitherto unknown. |

| Pindapixaragen. n. (Copepoda, Poecilostomatoida, Ergasilidac) é proposto para uma nova espécie, Ρ tarira,coletada dos filamentos branquiais de Hoplias malabaricus(Bloch, 1794) do Rio Guaporé, próximo a Surprêsa, Rondônia, Brasil. A espécie do novo gênero é caracterizada, principalmente, por apresentar um tamanho pequeno (382 a 577 μm), antena com uma grande garra e o terceiro segmento extremamente reduzido. |

| Precopulatory mate guarding and mating behaviour of Tachidius discipes Giesbrecht, 1881, has been analysed using a video camera mounted on a microscope. Males preferably accompany fourth or fifth stage female copepodids during precopulatory mate guarding; only rarely are third copopodid stages guarded. Rare cases of males clasping juvenile males are also known. Males are active during mate guarding and constantly change the site of attachment of their antennules. This behaviour may ensure continued association of the adult male with the juvenile copepodid when the latter moults during the mate guarding phase. The final moult of the female, once observed only, lasts only 2 minutes. Copulation immediately follows but is preceded by the male’s control of the... |

| Chitin was estimated in samples of planktonic crustaceans living in Calvi Bay (Corsica). The percentages of chitin, with respect to dry weight, are comprised between 3.10% in Clausocalanus spp. and 12.22% in Cladocera (mainly Evadne ). The percentage of chitin remained approximatively constant during larval development in Calanus helgolandicus (3.26%). Using these results and the values of total biomass and production estimated by Dauby (1985) at the same place during a complete annual cycle (1983-1984), chitin biomass and production were calculated for every planktonic crustacean species (or group of species) and for the whole crustacean plankton. Daily chitin production was maximum during May (20.06 mg.m super(-2)/d). As far as the whole year is... |

| ABSTRACT Ergasilus von Nordmann, 1832 is the type and the most speciose genus of Ergasilidae, with more than 150 valid species. The first species of this genus, Ergasilus iheringi Tidd, 1942, was described from the Neotropical Region, from the gills of Hoplias malabaricus (Bloch, 1794). Since then, 35 new species of Ergasilidae have been described from the Neotropics. However, a reanalysis of the available type specimens of E. iheringi revealed features that suggest that it represents a lineage independent from Ergasilus. Consequently, we propose Tiddergasilus gen. nov. (Ergasilidae: Cyclopoida) to accommodate T. iheringi (Tidd, 1942) comb. nov. The species was re-examined and redescribed based on available type specimens. Tiddergasilus gen. nov. is... |

| Psammocyclopina georgei sp. n. is described from submersed sands in the Magellan Strait, South Atlantic Ocean. This is the second species of the genus, previously known only from the Indian Ocean (Mozambique). Psammocyclopina Wells, 1967 is the sistergroup of Metacyclopina Lindberg, 1953. Psammocyclopinidae fam. n. is accordingly proposed to unify these genera into one monophyletic unit. The sistergroup of the new family is a cluster of cyclopinid genera composed of Cyclopinodes Wilson, 1932, Pseudocyclopina Lang, 1946, Parapseudocyclopinodes Lindberg, 1961, Hemicyclopina Herbst, 1952, Procyclopina Herbst, 1955, Heterocydopina Plesa, 1968, Neocyclopina Herbst, 1952, and an as yet undescribed new genus (Martinez Arbizu, in prep.). Global occurrence of... |

| Two species of Lepeophtheirus Nordmann, 1832 parasitic on the ariid fish Netuma barba Lacépède, 1803, and the bothiid fish Paralichthys sp. from the coastal zone of the State of Rio de Janeiro, are redescribed and illustrated: L. bagri Dana, 1852, and L. monacanthus Heller, 1865. New junior synonyms for these species are proposed: L. marginatus syn.n., L. christianensis syn.n. and L. platensis syn.n. of L. bagri and L. unispinosus syn.n. of L. monacanthus. |
