Owenia dichotoma n. sp. is characterised by a very short branchial crown of about 1/3 of thoracic length which bears short, dichotomously- branched tentacles provided with the major division close to the base of the crown. Owenia picta n. sp. is characterised by a long branchial crown of about 4/5 of thoracic length provided with no major divisions, ventral pigmentation on thorax and the presence of deep ventro-lateral groove on the first thoracic chaetiger. A key of Owenia species hitherto described or reported in South East Asia and Australasia regions is provided based on characters of the branchial crown.

  • Owenia Fusiformis – a Basally Branching Annelid Suitable For
    Helm et al. BMC Evolutionary Biology (2016) 16:129 DOI 10.1186/s12862-016-0690-4 RESEARCH ARTICLE Open Access Owenia fusiformis – a basally branching annelid suitable for studying ancestral features of annelid neural development Conrad Helm*, Oliver Vöcking, Ioannis Kourtesis and Harald Hausen Abstract Background: Comparative investigations on bilaterian neurogenesis shed light on conserved developmental mechanisms across taxa. With respect to annelids, most studies focus on taxa deeply nested within the annelid tree, while investigations on early branching groups are almost lacking. According to recent phylogenomic data on annelid evolution Oweniidae represent one of the basally branching annelid clades. Oweniids are thought to exhibit several plesiomorphic characters, but are scarcely studied - a fact that might be caused by the unique morphology and unusual metamorphosis of the mitraria larva, which seems to be hardly comparable to other annelid larva. In our study, we compare the development of oweniid neuroarchitecture with that of other annelids aimed to figure out whether oweniids may represent suitable study subjects to unravel ancestral patterns of annelid neural development. Our study provides the first data on nervous system development in basally branching annelids. Results: Based on histology, electron microscopy and immunohistochemical investigations we show that development and metamorphosis of the mitraria larva has many parallels to other annelids irrespective of the drastic changes in body shape during metamorphosis. Such significant changes ensuing metamorphosis are mainly from diminution of a huge larval blastocoel and not from major restructuring of body organization. The larval nervous system features a prominent apical organ formed by flask-shaped perikarya and circumesophageal connectives that interconnect the apical and trunk nervous systems, in addition to serially arranged clusters of perikarya showing 5-HT-LIR in the ventral nerve cord, and lateral nerves.

Abstract 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.

These results indicate that the last common ancestor of Annelida was a tube-dwelling organism. They also challenge traditional evolutionary hypotheses of different organ systems, among them the nervous system. In textbooks the central nervous system is described as consisting of a ganglionic ventral nervous system and a dorsally located brain with different tracts that connect certain parts of the brain to each other. Only limited information on the fine structure, however, is available for Oweniidae, which constitute the sister group (possibly together with Magelonidae) to all remaining annelids.

  • Annelid Diversity: Historical Overview and Future Perspectives
    diversity Review Annelid Diversity: Historical Overview and Future Perspectives María Capa 1,* and Pat Hutchings 2,3 1 Departament de Biologia, Universitat de les Illes Balears, 07122 Palma, Spain 2 Australian Museum Research Institute, Australian Museum, 1 William Street, Sydney 2010, Australia; [email protected] 3 Biological Sciences, Macquarie University, North Ryde 2109, Australia * Correspondence: [email protected] Abstract: Annelida is a ubiquitous, common and diverse group of organisms, found in terrestrial, fresh waters and marine environments. Despite the large efforts put into resolving the evolutionary relationships of these and other Lophotrochozoa, and the delineation of the basal nodes within the group, these are still unanswered. Annelida holds an enormous diversity of forms and biological strategies alongside a large number of species, following Arthropoda, Mollusca, Vertebrata and perhaps Platyhelminthes, among the species most rich in phyla within Metazoa. The number of currently accepted annelid species changes rapidly when taxonomic groups are revised due to synonymies and descriptions of a new species. The group is also experiencing a recent increase in species numbers as a consequence of the use of molecular taxonomy methods, which allows the delineation of the entities within species complexes. This review aims at succinctly reviewing the state-of-the-art of annelid diversity and summarizing the main systematic revisions carried out in the group. Moreover, it should be considered as the introduction to the papers that form this Special Issue on Systematics and Biodiversity of Annelids. Keywords: Annelida; diversity; systematics; species; new developments; special issue Citation: Capa, M.; Hutchings, P. Annelid Diversity: Historical Overview and Future Perspectives.

  • Phylogenetic Relationships Within Oweniidae Rioja (Polych Aeta, Annelida)
    Phylogenetic relationships within Oweniidae Rioja (Polych aeta, Annelida) Gustavo Sene-Silva 1 ABSTRACT. The Oweniidae consist of five genera of tubiculous polychaetes OCCUl"­ ring in ali oceans from tropical to po lar areas: Owenia Delle Chiaje, 1842, Myriochele Malmgren, 1867, Galarhowenia Kirkegaa rd , 1959, Myriowenia Hartman , 1960 and Myrioglobula Hartman, 1967. The gro up is regarded as monophyleti c based on lhe presence of dense fields of bidentate neuropodial hooks. Fo urteen species were submitted to a c1adi sti c anal ysis in PAU P 3. 1.1 with the usage of 19 morphological characters. The taxonomic status of the ingro up taxa co uld be evaluated and it has been found that: ( I ) Owenia, Myriowenia and Myrioglobula are monophyleti c, and (2) Myriochele, and Galalhowenia are both paraphyletic taxa. KEY WORDS. Pol ychaeta, Owen iidae, phylogeny, systematics The Oweniidae Rioja, 1917 are polychaetes with large bathymetric range. They are usually collected from intertidal zones to shallow waters and are rare in great depths, being present in ali oceans from tropical to polar areas. The Oweniidae currently consist offive genera: Owenia Dell e Chiaje, 1842, Myriochele Malmgren, 1867, Galathowenia Kirkegaard, 1959, Myriowenia Hartman, 1960, and Myrioglo­ bula Hartman, 1967. They ali inhabit tubes. In terms of taxonomical diagnosis, these genera seem to be relatively well defined, except for Myriochele and Galathowenia. Some oweniid polychaetes, as for example Myriochele fragilis Nilsen & Holthe, 1985 and M. longicollaris Hartmann-Schroder & Rosenfeldt, 1989, have been described and ranked in the cited genus. Howeve r, the description of their head region (a collar-like cyJindrical structure anterior to the mouth) does not fit with th e ori ginal di agnos is of a globular head for Myriochele (MALMGREN 1867).

EvoDevo (2021) 12:5 https://doi.org/10.1186/s13227‑021‑00176‑z EvoDevo RESEARCH Open Access Early embryogenesis and organogenesis in the annelid Owenia fusiformis Allan Martín Carrillo‑Baltodano* , Océane Seudre , Kero Guynes and José María Martín‑Durán† Abstract Background: Annelids are a diverse group of segmented worms within Spiralia, whose embryos exhibit spiral cleav‑ age and a variety of larval forms. While most modern embryological studies focus on species with unequal spiral cleavage nested in Pleistoannelida (Sedentaria Errantia), a few recent studies looked into Owenia fusiformis, a mem‑ ber of the sister group to all remaining annelids+ and thus a key lineage to understand annelid and spiralian evolution and development. However, the timing of early cleavage and detailed morphogenetic events leading to the forma‑ tion of the idiosyncratic mitraria larva of O. fusiformis remain largely unexplored. Results: Owenia fusiformis undergoes equal spiral cleavage where the frst quartet of animal micromeres are slightly larger than the vegetal macromeres. Cleavage results in a coeloblastula approximately 5 h post‑fertilization (hpf) at 19 °C. Gastrulation occurs via invagination and completes 4 h later, with putative mesodermal precursors and the chaetoblasts appearing 10 hpf at the dorso‑posterior side. Soon after, at 11 hpf, the apical tuft emerges, followed by the frst neurons (as revealed by the expression of elav1 and synaptotagmin-1) in the apical organ and the prototroch by 13 hpf. Muscles connecting the chaetal sac to various larval tissues develop around 18 hpf and by the time the mitraria is fully formed at 22 hpf, there are FMRFamide+ neurons in the apical organ and prototroch, the latter forming a prototrochal ring.

    Biodiversity and Biogeography of Polychaetes (Annelida): Globally and in Indonesia Joko Pamungkas A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy in Marine Science, University of Auckland October 2020 Chapte Abstract This thesis presents a review of the biodiversity of polychaete worms (Annelida) and their distribution across the globe. It also provides an evaluation of polychaete biodiversity studies in Indonesia and a description of a new polychaete species collected from Ambon Island, Province of Maluku, Indonesia. I reviewed polychaete data from the World Register of Marine Species (WoRMS), and found that 11,456 accepted polychaete species (1417 genera, 85 families) have been formally described by 835 first authors since the middle of the 18th century. A further 5200 more polychaete species are predicted to be discovered by the year 2100. The total number of polychaete species in the world by the end of the 21st century is thus anticipated to be about 16,700 species. While the number of both species and authors increased, the average number of polychaete species described per author decreased. This suggested increased difficulty in finding new polychaete species today as most conspicuous species may have been discovered. I analysed polychaete datasets from the Global Biodiversity Information Facility (GBIF), the Ocean Biogeographic Information System (OBIS), and my recently published checklist of Indonesian polychaete species, and identified 11 major biogeographic regions of polychaetes. They were: (1) North Atlantic & eastern and western parts of the Mediterranean, (2) Australia, (3) Indonesia, (4) New Zealand, (5) the Atlantic coasts of Spain and France, (6) Antarctica and the southern coast of Argentina, (7) Central Mediterranean Sea, (8) the western coast of the USA, (9) the eastern part of the Pacific Ocean, (10) Caribbean Sea and (11) Atlantic Ocean.
