Ascidiacea, Phlebobranchia, Corellidae) in the Southern Hemisphere with Description of a New Species
Zootaxa 3702 (2): 135–149 ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ Article ZOOTAXA Copyright © 2013 Magnolia Press ISSN 1175-5334 (online edition) http://dx.doi.org/10.11646/zootaxa.3702.2.3 http://zoobank.org/urn:lsid:zoobank.org:pub:E972F88B-7981-4F38-803D-8F4F92FE6A37 The genus Corella (Ascidiacea, Phlebobranchia, Corellidae) in the Southern Hemisphere with description of a new species FRANÇOISE MONNIOT Muséum national d’Histoire naturelle, 57 rue Cuvier Fr 75231 Paris cedex 05, France.E-mail : [email protected] Abstract In the Southern Hemisphere the species attributed to Corella eumyota, Traustedt, 1882 are likely more varied than previously expected. This ascidian species was described from specimens collected at Valparaiso (Chile). Until now it was considered as a widely distributed species in the southern hemisphere. New collections from Chile and the Antarctic area have allowed to separate two species and re-establish Corella antarctica Sluiter, 1905 as a valid species (Alurralde 2013).A morphological re- examination of many specimens from the MNHN collections and especially recent surveys as CEAMARC and REVOLTA confirms that Antarctic specimens from the Antarctic Peninsula and Terre Adélie obviously differ from sub-Antarctic material more varied than previously estimated. On the other hand, C. eumyota invasive in Europe (Lambert 2004) has been shown to be the same as specimens from Chile, New Zealand and other sub-Antarctic regions. The present morphological study compares Corella from different regions and describes a new species Corella brewinae n. sp that is found living mixed with C. eumyota populations. Key words: Ascidians, Corellidae, Antarctic, Sub-Antarctic, new species Introduction The genus Corella was created by Hancock (1870) for Ascidia parallelogramma Müller, 1776. -
Phlebobranchia of CTAW
PHLEBOBRANCHIA PHLEBOBRANCHIA The suborder Phlebobranchia (order Enterogona) is characterised by having unpaired gonads present only on the same side of the body as the gut. As in Stolidobranchia, the body is not divided into different sections (such as thorax, abdomen and posterior abdomen) as the gut is folded up in the parietal body wall outside the pharynx and the large branchial sac occupies the whole length of the body. Usually the branchial sac (which is flat, without folds) has internal longitudinal vessels (although only vestiges remain in Agneziidae). Epicardial sacs do not persist in adults as they do in Aplousobranchia, although excretory vesicles (nephrocytes) embedded in the body wall over the gut are known to originate from the embryonic epicardium in Ascidiidae and Corellidae. Most phlebobranchs are solitary. However, Plurellidae Kott, 1973 includes both solitary and colonial forms, and Perophoridae Giard, 1872 are all colonial. Replication in Perophoridae is from ectodermal epithelium (rather than endodermal or mesodermal tissue the mesodermal tissue of the vascular stolon (rather than the endodermal tissue as in most as in Aplousobranchia). The process of replication has not been investigated in Plurellidae. Phlebobranch taxa occurring in Australia are documented in Kott (1985). Family level taxa are characterised principally by the size and form of the branchial sac including the number of branchial vessels and form of the stigmata; the form, size and position of the gonads; and the habit (colonial or solitary) of the taxon. Berrill (1950) has discussed problems in assessing the phylogeny of Perophoridae. References Berrill, N.J. (1950). The Tunicata. Ray Soc. Publs 133: 1–354 Giard, A.M. -

Received: 24 May 2017; Accepted: 26 June 2017; Published: 1 July 2017 Abstract: Two novel oxazole-thiazole containing cyclic hexapeptides, bistratamides M (1) and N (2) have been isolated from the marine ascidian Lissoclinum bistratum (L. bistratum) collected in Raja Ampat (Papua Bar, Indonesia). The planar structure of 1 and 2 was assigned on the basis of extensive 1D and 2D NMR spectroscopy and mass spectrometry. The absolute configuration of the amino acid residues in 1 and 2 was determined by the application of the Marfey’s and advanced Marfey’s methods after ozonolysis followed by acid-catalyzed hydrolysis. The interaction between zinc (II) and the naturally known bistratamide K (3), a cyclic hexapeptide isolated from a different specimen of Lissoclinum bistratum, was monitored by 1H and 13C NMR. The results obtained are consistent with the proposal that these peptides are biosynthesized for binding to metal ions. -

This chordate subphylum contains a particularly diverse range of reproductive 21 methods, regenerative abilities and life-history strategies. Consequently, tunicates provide an 22 extraordinary perspective into the emergence and diversity of chordate traits. Currently 23 published tunicate genomes include three Phlebobranchiae, one Thaliacean, one Larvacean 24 and one Stolidobranchian. To gain further insights into the evolution of the tunicate phylum, 25 we have sequenced the genome of the colonial Stolidobranchian Botrylloides leachii. -

Ruiz Legacy Program Abstract: SSpecies introductions have increased dramatically in number, rate, and magnitude of impact in recent decades. In marine systems, invertebrates are the largest and most diverse component of coastal invasions throughout the world. Ascidians are conspicuous and well-studied members of this group, however, much of what is known about their invasion history is limited to particular species or locations. Here, we provide a large-scale assessment of invasions, using an extensive literature review and standardized field surveys, to characterize the invasion dynamics of non-native ascidians in the continental United States and Alaska. -

Biodiversity Data Journal 4: e9273. https://doi.org/10.3897/BDJ.4.e9273 Abstract Background The checklist of the ascidian fauna (Tunicata: Ascidiacea) of Greece was compiled within the framework of the Greek Taxon Information System (GTIS), an application of the LifeWatchGreece Research Infrastructure (ESFRI) aiming to produce a complete checklist of species recorded from Greece. This checklist was constructed by updating an existing one with the inclusion of recently published records. All the reported species from Greek waters were taxonomically revised and cross-checked with the Ascidiacea World Database. New information The updated checklist of the class Ascidiacea of Greece comprises 75 species, classified in 33 genera, 12 families, and 3 orders. In total, 8 species have been added to the previous species list (4 Aplousobranchia, 2 Phlebobranchia, and 2 Stolidobranchia). Aplousobranchia was the most speciose order, followed by Stolidobranchia. Most species belonged to the families Didemnidae, Polyclinidae, Pyuridae, Ascidiidae, and Styelidae; these 4 families comprise 76% of the Greek ascidian species richness. The present effort revealed the limited taxonomic research effort devoted to the ascidian fauna of Greece, © Antoniadou C et al. -

This list is certainly incomplete. The taxonomy follows that of the World Register of Marine Species (WoRMS database, www.marinespecies.org) and the Integrated Taxonomic Information System (ITIS, www.itis.gov).
