| Despite the importance of Oligochaeta to the dynamics of aquatic ecosystems and to studies of the biology of pollution, there is currently a dearth of information on this group's ecology in Brazil. The aim of this study was to describe the Oligochaeta fauna in four watercourses - three urban and one rural - in the state of São Paulo: the Pinheirinho stream, the Água Branca stream, the Monjolinho River and the Gouveia stream, respectively. Sediment samples were taken with a Van Veen grab in two areas from each watercourse, during the summer and winter of 2001. In all collection areas, measurements of the pH, electrical conductivity, dissolved oxygen and turbidity of the water were made with a Horiba U-10 device. Principal component analysis showed that axes... |

| A very large collection of Naididae of the West Indies (153 localities), Suriname (15), Venezuela (2) and Florida (1) is studied. Five new species Nais barua, Dero scalariformis, D. tuna, Aulophorus kalina, A. barbatus are described. Dero magna, D. trifida, Aulophorus tridentatus, Allonais japonica, Pristina sima are redescribed. The 46 Naididae species of the West Indies are discussed by their taxonomy, distribution and habitat. |
