- Biodiversidad de crustáceos peracáridos en el delta del Río Orinoco, Venezuela Alberto Martín Yusbelly J. Díaz Díaz Biología isopod tanaids density amphipods diversity Biodiversity of peracarid crustaceans in the Orinoco River Delta, Venezuela. The composition,abundance, diversity and density of benthonic peracarid crustaceans were studied in the Orinoco river delta,Venezuela. Samples were collected at 18 sites distributed in five areas: one at the high delta, two at the mediumsector and two at the low delta. Two field seasons were included: high waters (18-28 November 2002) and lowwaters (8-19 May 2003). Three samples were dredged at each sampling site, identifying more than 510 specimensbelonging to eight families and 11 species: Amphipoda (three families, six species), Isopoda (one family,one species), Tanaidacea (two families, three species), Cumacea (one family) and Mysida (one family, onespecies). Two species (Discapseudes surinamensis and Halmyrapseudes spaansi) and an unidentified species ofKalliapseudes are new records for Venezuela. Their density and distribution suggest that a salinity gradient influencedlongitudinal distribution: greater densities and species richness were in the lower delta, near the mouth ofthe Mariusa and Winikina rivers.
