ABSTRACT

This study aimed a survey of Oligochaeta species in three different regions of Mato Grosso do Sul state (Baía, Ivinhema and Negro) in diverse environments (rivers, lakes, connecting channels). We recorded 41 Oligochaeta species, distributed in five families (Narapidae, Haplotaxidae, Opistocystidae, Alluroididae, and Naididae).
