L'examen de 110 échantillons pélagiques el de 16 échantillons littoraux de plusieurs corps d'eaux du bassin moyen de l'Orénoque (lac de barrage, lacs d'inondation du système Orénoque et Caroni, rivières) a permis d'identifier 58 taxa de Cladocères, dont 24 sont nouveaux pour la faune vénézuélienne. 2 espèces, Alona ovata et Bosmînopsis macaguensis, sont nouvelles pour la science. Alona karelica, élément paléarctique, n'avait jamais été mentionnée sur le continent américain. 35 % de la faune étudiée sont représentés par des Formes néotropicales, dont 8 endémiques sud-américaines.Une partie taxonomique illustrée est consacrée à 13 espèces rares ou peu connues. La répartition des espèces dans les milieux prospectés et dans les deux catégories d'eaux blanches et d'eaux noires, a été étudiée. La faune la plus riche de Cladocères a été observée dans les lacs d'inondation de l'Orénoque, la diversité spécifique étant due aux formes littorales appartenant principalement à la famille des Chydoridae.En Cladocera of several water bodies in the middle basin of the Orinoco river (Venezuela).Keywords : Cladocera, taxonomy, ecology. Venezuela, Orinoco.The examination of 110 pelagic samples and 16 littoral samples from several water bodies in the middle basin of the Orinoco river (lakes formed by barrage or inundation of the Orinoco and Caroni river systems) revealed 58 taxa of Cladocera, of which 24 are new to the Venezuelan launa. Two species, Alona ovata and Bosmînopsis macaguensis, are new to science. Alona karelica, a palaearctic species, has never been recorded before on the continent of America. 35 % of the fauna studied are represented by neotropical forms, of which eight are endemic to South America.An illustrated taxonomic section deals with 13 species that are rare or little known. The distribution of species was studied in the environment examined and in the two categories of white and black waters. The richest cladoceran fauna was found in the lakes formed by inundation of the Orinoco, the species diversity being due to littoral forms, chiefly in the Family Chydoridae.In the pelagic environment, white-water bodies were characterised by the species association Moina minuta, Ceriodaphnia cornuta, Bosmina tubicen, and Bosminopsis deitersi, and black-water bodies by the dominance of Bosminidae : Bosmina hagmanni, Bosminopsis macaguensis, Bosminopsis deitersi, Ceriodaphnia cornuta. The case of Daphnia gessneri, generally considered endemic to the Amazon-Orinoco system and present in a single survey, is discussed. -IntroductionLes données taxonomiques, biogéographiques et écologiques sur les Cladocères néotropicaux sont très limitées (Collado & al., 1984 Brehm (1953Brehm ( , 1957.

Thirty-five cladocerans species are recorded from La Española lagoon in the Orinoquia region of Colombia; all are new records for Meta Department and 10 for Colombia. With the addition of these new reports, the total number of cladocerans for Colombia and the Meta department is increased by 124 and 38 species, respectively. The cladoceran fauna from the surveyed area is represented mainly by widespread species, commonly found in the Neotropical regions, but local morphological data are scarce in the regional literature. Brief diagnostic description of 18 species of cladoceran fauna recorded of the Meta department-Colombia are provided together with illustrations of taxonomically significant appendages, morphological remarks, notes on the variability of some species, and their distribution.

-Zooplankton plays key roles in structuring interactions in aquatic communities but often remain undescribed in many water systems. This paper reports seventeen species of the Cladocera (Crustacea: Branchiopoda) from Laguna de Navío Quebrado, all of them new records for La Guajira Department, Colombia. The Cladocera assemblages include mostly the Neotropical taxa associated with vegetation. This paper also serves as the first compilation of the data on the Cladocera of this region and includes brief remarks, descriptions and illustrations of some species with additional notes on their distribution.
