New described species/Taxonomic News:


RUHNKE, T.R. & CAIRA, J.N. & COX, A. 2015: The cestode order Rhinebothriidea no longer family-less: A molecular phylogenetic investigation with erection of two new families and description of eight new species of Anthocephalum. Zootaxa, 3904 (1): 51–81
New Family: Escherbothriidae
New species: Anthocephalum decrisantisorumAnthocephalum healyae,Anthocephalum jensenaeAnthocephalum mattisiAnthocephalum meadowsi,Anthocephalum odonnellae, Anthocephalum papefayi, Anthocephalum philruschi
Abstract: The spiral intestines of a total of 30 specimens of 14 species of batoids from around the world were examined for rhinebothriideans. These consisted of Taeniura grabata, Dasyatis margaritella, and Dasyatis sp. from Senegal, Dasyatis americanafrom Florida, Dasyatis dipterura and Dasyatis longa from México, Himantura jenkinsii, Himantura leoparda, Himantura uarnak 2, Urogymnus asperrimus 1, and Neotrygon kuhlii 4 from Australia, in addition to Himantura uarnacoides and Neotrygon kuhlii 1 from Borneo. Each of these hosted one or more species of Anthocephalum. Eleven of the cestode species were new to science; four represented described species. In addition, Urotrygon aspidura from Costa Rica hosted a species of Escherbothrium. Sufficient material was available for formal description of the following eight species ofAnthocephalumA. decrisantisorum n. sp., A. healyae n. sp., A. jensenae n. sp., A. mattisi n. sp., A. meadowsi n. sp., A. odonnellae n. sp., A. papefayi n. sp., and A. philruschi n. sp. These species differ from their nine described congeners in overall size, number of proglottids and marginal loculi, number and arrangement of testes, apical sucker size, arrangement and distribution of vitelline follicles particularly with respect in the post-poral field, and muscularity of the genital pore. The diagnosis ofAnthocephalum is emended slightly to accommodate these new species. Material of four previously described Anthocephalum species, seven of the novel Anthocephalumspecies described here, 3 undescribed Anthocephalum species, and the species ofEscherbothrium was preserved in 95% ethanol and partial 28S rDNA (D1-D3) and complete 18S rDNA sequence data were generated de novo. These data were combined with data from GenBank for Anthocephalum cf. centrurum (recognized as A. mattisi n. sp. below) and 29 species representing 12 other putative rhinebothriidean genera. Phylogenetic analyses using Bayesian Inference and Maximum Likelihood methods were conducted using a total of five representatives of the Lecanicephalidea, Cathetocephalidea and “Tetraphyllidea” as outgroups. The analyses yielded trees that were largely congruent and that supported the existence of four major subgroups of rhinebothriideans. Family designations were established for each of these clades. Echeneibothriidae was elevated from subfamily to family level to accommodate the group consisting of Echeneibothrium and Pseudanthobothrium; this family is unique in retaining the apical organ (as a myzorhynchus) into adulthood. Rhinebothriidae was elevated from subfamily to family level to accommodate the group consisting ofRhabdotobothriumRhinebothriumRhinebothroidesRhodobothriumScalithrium andSpongiobothrium. This family is distinctive in its lack of apical suckers and also of a definitive anterior/posterior orientation to the bothridia. Anthocephaliidae n. fam. was established to house Anthocephalum and taxa identified as New Genus 1, New Genus 2, and New Genus 4 by previous authors. The bothridia of its members exhibit a conspicuous anterior/posterior orientation signaled by the presence of an apical sucker. In addition, its members bear marginal loculi or one or more rows of facial loculi and vitelline follicles that are usually interrupted by the ovary. Escherbothriidae n. fam. was established to house Escherbothrium and the taxon identified as New Genus 3 by previous authors. It most closely resembles Anthocephaliidae but the facial loculi are arranged in columns anteriorly and rows posteriorly, rather than arranged in multiple rows or entirely lacking. A key to the families is also provided.

KODÁDKOVÁ, A. & BARTOŠOVÁ-SOJKOVÁ, P. & HOLZER, A.S. & FIALA, I. 2015Bipteria vetusta n. sp. - an old parasite in an old host: tracing the origin of myxosporean parasitism in vertebrates. International Journal for Parasitology, in press
New species: Bipteria vetusta
Abstract: Myxosporea (Myxozoa), a group of parasitic Cnidaria, use mostly bony fishes (Teleostei) as intermediate hosts; however, they can also parasitize other vertebrates such as cartilaginous fish (Chondrichthyes). Molecular data of myxosporeans from sharks and rays (Elasmobranchii) revealed these parasites to be one of the most basal representatives in the myxosporean phylogenetic tree, suggesting their ancient evolutionary history. A new myxosporean species, Bipteria vetusta n. sp., was found in the gall bladder of rabbit fish, Chimaera monstrosa(Holocephali; Chondrichthyes), and ssrDNA-based phylogeny revealed its basal position within the marine myxosporean lineage. Molecular dating based on ssrDNA analysis suggested the origin of a stem lineage leading to the marine myxosporean lineage at the time of the origin of Chondrichthyes in the Silurian era. The two common lineages of Myxozoa, Myxosporea and Malacosporea, were estimated to have split from their common ancestor in the Cambrian era. Tracing the history of evolution of the "vertebrate host type" character in the context of molecular dating showed that cartilaginous fish represented an ancestral state for all myxosporeans. Teleosts were very likely subsequently parasitized by myxozoans four times, independently. Myxosporean radiation and diversification appear to correlate with intermediate host evolution. The first intermediate hosts of myxosporeans were cartilaginous fish. When bony fish evolved and radiated, myxosporeans switched and adapted to bony fish, and subsequently greatly diversified in this new host niche. We believe that the present study is the first attempt at molecular dating of myxozoan evolution based on an old myxosporean species - a living myxosporean fossil.




THIES, D. & VESPERMANN, J. & SOLCHER, J. (2014): Two new neoselachian sharks (Elasmobranchii, Neoselachii, Synechodontiformes) from the Rhaetian (Late Triassic) of Europe. Palaeontographica, Abt. A, 303 (4-6): 137-167
New Genus: Parascylloides
New species: Synechodus seinstedtensis, Parascylloides turnerae
Abstract: Two new Late Triassic shark species (Synechodus seinstedtensis sp. nov.,Parascylloides turnerae gen. nov. sp. nov.) belonging to the extinct order Synechodontiformes DUFFIN & WARD, 1993 (Chondrichthyes, Elasmobranchii, Neoselachii) are described on isolated oral teeth from Rhaetic deposits of North Germany and England. The term "polyhemiaulacorhize" is introduced for the synechodontiform type of root architecture in order to replace the misleading term "pseudopolyaulacorhize". The teeth of Parascylloides turnerae gen. nov. sp. nov. were identified previously as symphyseals or parasymphyseals of Rhomphaiodon minor(AGASSIZ, 1837). They are considered here as belonging to a different, new species because of their frequency and their morphological differences to other Triassic neoselachian teeth. The teeth of both new species show a triple-layered enameloid microstructure consisting of an external shiny-layered enameloid (SLE), a middle parallel-bundled enameloid (PBE) and an internal tangled-bundled enameloid (TBE). InSynechodus seinstedtensis sp. nov. the PBE contains probably radial bundles of apatite cristallites whereas these are lacking in the PBE of Parascylloicks turneraegen. nov. sp. nov.. The systematical significance of the presence or absence of radial bundles in the PBE remains unclear.

New shark fin identification tool released

News Release

Convention on International Trade in
Endangered Species of Wild Fauna and Flora (CITES)

29. January 2015

Geneva, 29 January 2015 – The Secretariat of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), welcomes the new software package for the identification of shark fins released today by the Food and Agriculture Organization of the United Nations (FAO).
The software application called iSharkFin is an innovative system that uses machine learning techniques to identify shark species from shark fin shapes. The software has been developed by FAO in collaboration with the University of Vigo with financial support of the Government of Japan and the CITES Secretariat – using funds provided by the European Union
The iSharkFin is an interactive process. Users take a standard photograph, select some characteristics of a fin and choose a few points on the fin shape, iSharkFin will automatically analyse the information, and identify the shark species from which the fin originated. iSharkFin is available for the identification of 35 shark species from dorsal fins and 7 species from pectoral fins, all from species commonly seen in international trade, including some species listed in the CITES Appendices. Further species will be added to the system.
Commenting on the launch of the new tool, Secretary-General John Scanlon said “We have heard regular calls for accurate, simple to use and cost-effective ways to identify shark fins in trade – and this new tool responds to these calls.  The iSharkFin is an excellent product for use by Customs, CITES authorities, and fishery inspectors and we congratulate the FAO on taking the initiative to prepare this tool and encourage its wide distribution and use”.
The new iSharkFin tool permits the identification of 35 shark species from dorsal fins and 7 species from pectoral fins. Many of these are found in international trade, including 4 CITES-listed species which are particularly fished and traded for their fins.
New CITES rules for sharks and manta rays
From 14 September 2014, international trade in specimens of five shark species and all manta ray species, including their meat, gills and fins, needs to be accompanied by permits and certificates confirming that they have been harvested sustainably and legally.
New controls adopted by CITES will apply to the oceanic whitetip shark (Carcharhinus longimanus), scalloped hammerhead shark (Sphyrna lewini), great hammerhead shark (Sphyrna mokarran), smooth hammerhead shark (Sphyrna zygaena), porbeagle shark (Lamna nasus) and manta rays (Manta spp.) as they are now included in CITES Appendix II.
