Abstract
Specimens of a previously undescribed oligochaete from the Bay of Rio de Janeiro, Brazil were determined to belong to a new family of microdiles within the order Tubificida, suborder Enchytraeina. The specimens are characterized by dorsal and ventral hair setae, spermathecae in VII, testes in XI, ovaries in XII, and a clitellum. The number of primitive characters present in the new species indicate that it is a primitive member of the order that diverged early from the evolutionary line leading to the Enchytraeidae.
