AB  - <i>Pionosyllis</i> Malmgren, 1867 is revised based on a cladistic analysis of the 41 species considered herein as valid, two newly described species in this paper (<i>Basidiosyllis victoriae</i> and <i>Opisthodonta russelli</i>), 11 species from other genera actually belonging, or related to, <i>Pionosyllis</i>, and 13 syllid species from different subfamilies. The phylogenetic analysis is based on 55 characters; a strict consensus Of 1200 equally parsimonious trees (length = 314 steps) was obtained. The clades containing species usually included within <i>Pionosyllis</i> are newly named within the frame of a new Linnean classification of the group (except for one, belonging to another subfamily). The diagnosis of <i>Pionosyllis</i> is emended, and five new genera arc proposed: <i>Synmerosyllis</i>, <i>Basidiosyllis</i>, <i>Westheidesyllis</i>, <i>Perkinsyllis</i> and <i>Brevicirrosyllis</i>. <i>Paraehlersia</i> San Martín, 2003, proved to be closely related to <i>Pionosyllis</i>. Seven species are transferred to <i>Opisthodonta</i> Langerhans, 1879, here emended, and three transferred to <i>Nudisyllis</i> Knox & Cameron, 1970 (according to San Martín & Hutchings, 2006). <i>Opisthodonta uraga</i> (Imajima, 1966) comb. nov. and <i>Perkinsyllis longisetosa</i> comb. nov. are redescribed. <i>Pionosyllis compacta</i> Malmgren, 1867, <i>P. stylifera</i> Ehlers, 1913, <i>P. gigantea</i> Moore, 1908, <i>P. enigmatica</i> (Wesenberg-Lund, 1950), and <i>Nudisyllis magnidens</i> (Day, 1953) comb. nov., are redescribed. <i>Pionosyllis marquesensis</i> Monro, 1939 and <i>P. procera</i> Hartman, 1965 likely belong to the Syllinae, thus they are not treated in the taxonomic account.
