“…Our results endorse the monophyly of the Oweniidae (as did Sene‐Silva, 2002) and four of the traditional oweniid genera if some synonymizations and nomenclatural changes are carried out . The monophyly of Owenia and Myriowenia has never been questioned owing to the presence of their characteristic head appendages (tentacular crown and grooved palps, respectively).…”

“…Remarks: Our phylogenetic analyses recover Myrioglobula species scattered within those traditionally assigned to Myriochele (Fig. 1A–D, unlike Sene‐Silva, 2002). Although the support value for this clade is not strong (Fig.…”

“…However, the position of these groups differs in the literature. The hypothesis proposed by Sene‐Silva (2002) recovered Myriowenia as the basal oweniid and Owenia as the most derived. Other authors (e.g.…”

“…The genus Galathowenia was defined by the shape of the prostomium with a ventral cleft (Kirkegaard, 1959) as opposed to the rounded anterior end in Myriochele (Kirkegaard, 1959, 1983; Fauchald, 1977; Blake, 1984, 2000; Parapar, 2001, 2003b, 2006), although this genus has been considered a junior synonym of Myriochele by some authors (e.g. Blake & Dean, 1973; Nilsen & Holthe, 1985; Hartmann‐Schröder, 1996; Cantone & Di Pietro, 1998; Sene‐Silva, 2002). After our analyses (Fig.…”

“…The phylogenetic relationships within Oweniidae have been addressed recently (Sene‐Silva, 2002), based on morphological data. Three of the five existing genera were recovered as monophyletic ( Owenia Delle Chiaje, 1844, Myrioglobula Hartman, 1967, and Myriowenia Hartman, 1960) whereas Myriochele Malmgren, 1867 and Galathowenia Kirkegaard, 1959, were retrieved as paraphyletic.…”

The family Oweniidae Rioja, 1917 is a small group of broadly distributed polychaetes whose relationships and position in the annelid tree are still poorly understood. A comprehensive revision of the group with reconsideration of character homologies and terminology under a phylogenetic framework was needed. We investigated the relationships of members of Oweniidae and other polychaetes by performing maximum parsimony analyses of 18 oweniid species of the five recognized genera to date and members of the families Siboglinidae, Sabellidae, Spionidae, Magelonidae, and Chaetopteridae. Phylogenetic hypotheses confirmed the monophyly of Oweniidae and suggested sister-group relationships with Magelonidae, although weakly supported. Analyses also recovered Owenia and Myriowenia as monophyletic and allowed recognition of Myrioglobula as a junior synonym of Myriochele based on the presence of acicular chaetae and the shape of the head. Implied weighting analyses supported these findings and recovered Galathowenia australis as sister group of Myriochele. The presence of acicular chaetae justifies the consideration of this species as belonging to Myriochele. Nomenclatural changes are proposed for those species previously considered as members of Myrioglobula, and these are: Myriochele antarctica comb. nov., Myriochele japonica comb. nov., Myriochele islandica comb. nov., Myriochele malmgreni comb. nov., and Myriochele australis comb. nov. After analyses and definition of generic diagnostic features, other new combinations include Galathowenia eurystoma comb. nov. and Galathowenia haplosoma comb. nov., previously considered as members of Myriochele. Taxonomic revision of Australian collections revealed the presence of Myriochele heruensis Gibbs, 1971, which is herein redescribed, and allowed the description of four new species: Galathowenia annae sp. nov., Galathowenia arafurensis sp. nov., Galathowenia quelis sp. nov., and Myriochele australiensis sp. nov., mostly from the east coast of Australia, in addition to the three recently well-documented species of Owenia. Australian species have been described, illustrated, and compared in detail with similar taxa. Distribution patterns and ecological notes have also been given. Keys to oweniid genera and Australian species are provided.

Based on the study of specimens previously identified as Myriochele heeri Malmgren, 1867 (Polychaeta, Oweniidae) in Icelandic waters collected during the BIOICE project, a redescription of this taxon is presented, a Pacific species-Myriochele olgae Blake, 2000-is reported, and one new species is described: Myrioglobula malmgreni sp. nov. Myriochele heeri is characterized by three short anterior uniramous chaetigers of similar length. The revision of the type series of M. heeri showed that the length of the anterior chaetigers and the chaetal composition is variable in the different specimens, thus demonstrating that more than one species is involved. Complementary anatomical (prostomial, foregut, and peristomial ciliary fields, ventral pharyngeal organ) and biological (food composition, tube ornamentation, body regeneration) observations from selected specimens are provided. Additions to the original description of Myrioglobula islandica Parapar, 2003a and an updated key to the species of Oweniidae recorded in Arctic and East Atlantic Boreal waters are also presented. Aspects on geographical distribution and phylogeny of the family are also discussed.
