NEWS/ OWN RESEARCH

New open access paper from Team Shark-references:

In addition to articulated, mostly formaldehyde-fixed and ethanol-preserved, taxidermy or anatomical specimens, sharks and rays are represented in scientific collections by numerous jaws and isolated teeth. These specimens often source from historical collections where existing informations about species, sex or geographic origin in many cases are scarce, incomplete or incorrect. The identification key for jaws and teeth presented herein focuses on squalomorph sharks, which comprise almost 34 % of all sharks with 179 species in 31 genera and 11 families. The key is essentially based on the following characters: vascularisation stage, labial apron, number of cusplets, distal heel, lingual ornamentation, cutting edge, and dentition kind. The key allows the identification to genus level. It is further supplemented by a comprehensive glossary of tooth morphological terms as well as an updated checklist of all currently described squalomorph sharks with indication of the distribution and the dental formula.

EEA Meeting 2019 in Rende

http://eulasmo.org/blog/eea-meeting-2019-in-rende/

The Dipartimento di Biologia, Ecologia e Scienze della Terra – University of Calabria (DIBEST), Gruppo Italiano Ricercatori Squali, Razze e Chimere (G.R.I.S.) and the Centro Studi Squali (C.S.S.) are excited to organize the 23^rd European Elasmobranch Association Meeting, which will take place in Rende (Italy) from the 16th to the 18th of October 2019.

We aim at creating a great forum where scientists, conservationists, students and all those interested in elasmobranchs will have an opportunity to share the results of their most exciting research, to look for synergies and find new collaborations.

During the conference, four plenary lectures, scientific sessions (orals and posters) and various workshops will take place. The sessions will deal with diverse topics, from evolutionary biology to ethology, from morphology to physiology, ecology and conservation. The conference will also include the Annual General Meeting of the EEA, multiple social activities, and the opportunity of exciting field underwater excursions. English will be the official conference language.

Please come back in the coming weeks to find out all the details about registration and related activities on the meeting’s website at www.dibest.unical.it/eea2019 and on the Facebook page at https://www.facebook.com/eea2019meeting/.

GRACE, M.A. & DOOSEY, M.H. & DENTON, J.S.S. & NAYLOR, G.J.P. & BART, H.L. & MAISEY, J.G. (2019): A new Western North Atlantic Ocean kitefin shark (Squaliformes: Dalatiidae) from the Gulf of Mexico. Zootaxa, 4619 (1): 109–120

New species: Mollisquama mississippiensis

Abstract: A new species of kitefin shark (Squaliformes; Dalatiidae) is described from the Gulf of Mexico (Western North Atlantic Ocean) based on five diagnostic features not seen on the only other known Mollisquama specimen, the holotype of Mollisquama parini Dolganov which was captured in the Eastern South Pacific Ocean. The new species, Mollisquama mississippiensis sp. nov.,is distinguished from its congener by a putative pit organ located ventrally just posterior of the lower jaw margin center, photophores irregularly distributed along many areas of the body, 16 distinct ventral-abdominal photophore aggregations, and two differences associated with the dentition. Other potential distinguishing features are 10 fewer vertebrae than Mollisquama parini and six morphometric proportional differences that exceeded +/- 20% from the holotype.

CICIMURRI, D.J. & KNIGHT, J.L. (2019): Late Eocene (Priabonian) elasmobranchs from the Dry Branch Formation (Barnwell Group) of Aiken County, South Carolina, USA. PaleoBios, 36: 1–31

New species: Isogomphodon aikenensis

Abstract: A survey of the Eocene (Priabonian) Dry Branch Formation exposed in Aiken County, South Carolina, resulted in the collection of thousands of fossil teeth and bone fragments. Two sites located near the city of Aiken proved to be particularly productive, and 24 species of elasmobranchs, 11 osteichthyans, and three reptiles (one crocodilian and two turtles) have been identified. Herein we focus on the elasmobranch species (17 sharks and seven rays) that are part of the assemblage, which includes a new species of daggernose shark, Isogomphodon aikenensis n. sp. Cicimurri and Knight. The fossils are derived from the upper part of the Dry Branch Formation, and the fossiliferous strata accumulated within a high energy nearshore marine depositional environment that was influenced by a river system. Based on the vertebrate and invertebrate fossils we identified, the water depth was less than 40 m, and surface water temperature was at least 22° C . Elasmobranch species composition is similar to other late Eocene elasmobranch assemblages reported from the Gulf and Atlantic Coastal plains, particularly Georgia, and several of the taxa indicate affinities to the Tethyan region.

Parasites:

MALEKI, L. & MALEK, M. & PALMS, H.W. (2019): Five new species of Acanthobothrium (Cestoda: Onchoproteocephalidea) from the long-tailed butterfly ray, Gymnura cf. poecilura (Elasmobranchii: Gymnuridae), from the Persian Gulf and Gulf of Oman. PaleoBios, 36: 1–31

New species: Acanthobothrium omanense, Acanthobothrium kurdistanense, Acanthobothrium halehae, Acanthobothrium makranense, Acanthobothrium persicum

Abstract: Five new species of Acanthobothrium Blanchard, 1848 are described from Gymnura cf. poecilura from the Gulf of Oman and Persian Gulf. They all belong to the Category 1 and can be differentiated from all congeners by a combination of characters, including marginal lappets on the bothridial rim, the lack of spinitrich microtriches on the proximal bothridial surfaces, the position of the genital pore in the posterior one fifth of the proglottid, the direction of the cirrus sac parallel and clinging to the ovarian lobe, the lack of post-vaginal testes, and the interruption of the vitelline follicles by the ovary. The five new species are morphologically similar to each other but differ among each other in their cephalic peduncle length, proglottid and testes number, and the apolysis status. The most similar species to this new group is Acanthobothrium fogeli Gloldstein, 1964 from the Gulf of Mexico. The new species differ from A. fogeli by the muscular pad size, cephalic peduncle length and having marginal lappets on the bothridial rim. the species of Acanthobothrium occurs in three families of elasmobranchs in the Gulf of Oman and Persian Gulf (Dasyatidae, Rhynchobatidae and Gymnuridae). The true identity of many hosts in the region is ambiguous. Therefore, we designated the sampled elasmobranch as G cf. poecilura in accordance to the previously molecular study on a few individuals from the region.

New species: Wenyonia sanyali

Abstract: The genus Wenyonia Woodland, 1923 contains 7 valid species. In this paper Wenyonia sanyalisp.n. is described and illustrated from the intestine of Chilloscyllium griseum (bamboo shark) from West Bengal, India. The species is characterized by an undifferentiated scolex, without grooves, furrows and bothria; absence of neck and 14–40 testes in apical region that differentiates it from the rest of the described species in the genus.
