ABSTRACT: Analysis of plankton samples from the lagoonal system La Española, Orinoquía region in Colombia yielded 2 new records of cladocerans: Bosminopsis brandorffi Rey et Vásquez, 1989 and Chydorus parvireticulatus Frey, 1987 (Crustacea: Cladocera). Morphological characters of B. brandorffi conforms to the original descriptions and can easily be identified by its important diagnostic characters: 1) preanal margin of postabdomen forming a long and robust projection; 2) ocular dome strongly projected; 3) large compound eye. C. parvireticulatus can be discriminated from its congeners in the faviformis-group: 1) anal margin of postabdomen longer than preanal and postanal porton, 2) valve covered by over 200 small honeycomb meshes, 3) the tip of rostrum acute and tapered. Both species are recorded for the first time in Colombia in the Orinoquia region.
KEY WORDS: Orinoquía, new record, taxonomy, microcrustaceans.
