Copepods are the dominant taxa in zooplankton communities of the ocean worldwide. Although bioluminescence of certain copepods has been known for more than a 100 years, there is very limited information about the structure and evolutionary history of copepod luciferase genes. Here, we report the cDNA sequences of 11 copepod luciferases isolated from the superfamily Augaptiloidea in the order Ca...

A new species of the copepod genus Tortanus (Atortus) (Copepoda: Calanoida), T. (A.) insularis, is described from the coastal region of Rodrigues Island, Mauritius, an isolated island in the south-western Indian Ocean. This new species can be assigned to an Indian faunal element, the recticauda species group, in the Indo-West Paci¢c recticauda species complex. It exhibits the closest relationsh...

Calanoid copepods are a well-recognized taxonomic group of Crustacea. They were already placed, with one cyclopoid (Scribella) and five calanoid (Acartia, Calanus, Candacia, Euchirus (= Euchaeta), Pontella) genera, under single unit, the Calanidae, by Dana [1]. Giesbrecht Sars two early principal contributors to taxonomy Copepoda, including Calanoida. Based on location body articulation, [2] di...

Centropages mohamedi sp. nov. (Copepoda: Calanoida) is described from specimens collected in zooplankton samples off Obhur Creek on the Saudi Arabian coast of the central Red Sea. The new species is most closely related to C. orsinii Giesbrecht, 1889, a species described from the Red Sea and widely distributed in the neritic waters of the Indo-West Pacific region. The new species is mainly dist...

A new species of paracalanid calanoid copepod Parvocalanusleei sp. n., is described from specimens collected in shallow waters of Western Korea. The new species is closely similar to Parvocalanusarabiensis (Kesarkar & Anil, 2010), Parvocalanuscrassirostris (F. Dahl, 1894), Parvocalanuslatus Andronov, 1972, and Parvocalanusscotti (Früchtl, 1923) in having two short terminal spines on the distal ...

Despite the key role of zooplankton communities in regulating water quality lentic ecosystems, they are absent from list biological elements Water Framework Directive (WFD) for assessment ecological status. Based on this, present work was a case study that aimed to understand relevance as bioindicator classifying reservoirs. For one year and each season, Torrão reservoir assessed using mandator...

During a plankton sampling programme around Al-Wajh area, Saudi Arabian coast of the northern Red Sea, a copepod Calanopia thompsoni A. Scott, 1909 (Calanoida: Pontellidae) was reported for the first time in the Red Sea. Both sexes are fully redescribed and compared to previous descriptions as well as the closely related species, Calanopia parathompsoni. The zoogeographical distribution of the ...

A new species of the calanoid copepod genus Pseudodiaptomus was collected from the Prasae River Estuary, Rayong Province, on the eastern coast of the Gulf of Thailand. This species is definitely assigned to the lobus species group sensu Walter (1986a). The female of the new species differs from other congeners in the elongate genital double-somite with a blunt process ventrally and the second u...
