Glyphohesione klatti Friedrich, 1950 , by monotypy. Remarks. Glyphohesione was described by Friedrich (1950) as a monospecific genus, with type species G. klatti classified as Hesionidae . Eliason (1962) redescribed G . klatti , as belonging to the genus Ancistrosyllis , placing it in Pilargidae . Glyphohesione has also been considered a junior synonym of Synelmis by Pettibone (1966) but it was re-established as a valid genus by Fitzhugh & Wolf (1990) . Later, a revision of Glyphohesione placed the genus back in Hesionidae and suggested both families form a monophyletic group (Licher 1994). Those different hypotheses, both based on morphology, might be explained because of the phylogenetic rooting strategy; while Fitzhugh & Wolf (1990) used Syllidae, Licher & Westheide (1994) selected Hesionidae ( Pleijel 2001 ) . Most recent taxonomic studies include Glyphohesione in Pilargidae . There was no previous record of Glyphohesione species for Brazil .
