Etymology The generic name Dioplosyllis is composed by the Greek prefix di-, meaning 'two', 'twice', or 'double', the Greek word hoplon, meaning 'weapon', and the generic name Syllis Lamarck, 1818, the type genus of the family Syllidae, and refers to the presence of a pharynx armed with two types of teeth on its anterior region: a big median dorsal tooth, and a ventral semicircle of numerous small teeth.

Etymology The generic name Dioplosyllis is composed by the Greek prefix di-, meaning 'two', 'twice', or 'double', the Greek word hoplon, meaning 'weapon', and the generic name Syllis Lamarck, 1818, the type genus of the family Syllidae, and refers to the presence of a pharynx armed with two types of teeth on its anterior region: a big median dorsal tooth, and a ventral semicircle of numerous small teeth. [details]Type designation The type is here considered to be fixed by original designation, though some doubts remain. After the diagnosis of Diplosyllis as a new genus, Gidholm (1962: 253) follows with the "Description du genre-type Diplosyllis cirrosa n. sp.". This seems to be a lapsus calami, while meaning to write "Description de la espèce-type Diplosyllis cirrosa n. sp." The issue remains however open to interpretation.
