Pseudoterebellinae new subfamily

( Seraphsidae )

Type. Terebellum Röding, 1798, p. 135 .

Reference Phylogeny. Figure 3 .

Definition. The maximum clade consisting of Terebellum terebellum ( Linnaeus, 1758) and all species that share a more recent common ancestor with it than with Seraphs sopitus ( Brander, 1766) , Mauryna plicata ( d’Archiac & Haime, 1853) or Diameza fragilis ( Defrance, 1825) .
