The family Histriobdellidae (Annelida, Polychaeta) including descriptions of two new species from Brazil and a new genus

Abstract

We review the family Histriobdellidae and provide species descriptions and notes on geographical distribution based on data from the literature. The morphological structures used in the systematics of this family are defined. A new genus, Dayus, is proposed and two new species from Brazil, Stratiodrilus robustus and S. circensis, are described.
