Upcoming Meetings:
EEA Meeting 2021 in Leiden, Netherlands
The 24th Annual Scientific Meeting of the European Elasmobranch Association is planned to be held by the Dutch member group Nederlandse Elasmobranchen Vereniging (NEV) in Leiden, the Netherlands between 3rd and 5th November, 2021.
NEV, in consultation with the EEA Board, has decided to tentatively organise this year’s EEA Meeting as an in-person meeting. Luckily, NEV was able of having secured the same prime venue at the fascinating Naturalis Biodiversity Center! Leiden is a beautiful old university town just 20 mins from Schiphol airport and international train station.
Prior to the main meeting we will organise an online session on November 2nd to allow those who cannot attend in person to contribute.
We understand that there is still a lot of uncertainty as far as travel etc. is concerned. In mid-July we will make the decision whether or not to host a live event.
If an in-person meeting is not possible the entire EEA2021 will be online.
In the coming weeks the website for early registration will be updated, as well as opening the abstract submission for either an online or live presentation.
Details can be found on the NEV website: https://www.elasmobranch.nl/eea2021/

TAXONOMIC NEWS/ NEW SPECIES
Extant Chondrichthyes:
WHITE, W.T. & ARUNRUGSTICHAI, S. & NAYLOR, G.J.P. (2021): Revision of the genus Mustelus (Carcharhiniformes: Triakidae) in the northern Indian Ocean, with description of a new species and a discussion on the validity of M. walkeri and M. ravidus. Marine Biodiversity, 51: 42
New species: Mustelus andamanensis
Abstract: The species of Mustelus Linck, 1790 occurring in the northern Indian Ocean are revised and a new species, Mustelus andamanensis sp. nov., is formally described. Previously considered to be conspecific with M. mosis Hemprich & Ehrenberg, 1899, the new species is currently only known from the Andaman Sea. The Red Sea and Arabian Sea populations of Mustelus mosis differ in vertebral counts and degree of coverage of buccopharyngeal denticles in the mouth, but these characters alone are not considered strong enough evidence to separate into two species. Mustelus andamanensis sp. nov. is genetically (based on NADH2 sequences) closest to M. mosis but differs in having a subdivided palatoquadrate (vs. palatoquadrate not divided). The new species is morphologically closest to M. widodoi White & Last, 2006, but differs in several morphological characters and on a molecular level. Mustelus stevensi White & Last, 2008 is confirmed from the northern Indian Ocean for the first time based on a single specimen taken off southeastern Myanmar. Mustelus walkeri White & Last, 2008 is found to be a junior synonym of M. antarcticus Günther, 1870. The use of buccopharyngeal patterns and vertebral counts in isolation from other morphological differences and molecular data in this genus is also discussed.

HODNETT, J.-P.M. & GROGAN, E.D. & LUND, R. & LUCAS, S.G. & SUAZO, T. & ELLIOTT, D.K. & PRUITT, J. (2021): Ctenacanthiform sharks from the Late Pennsylvanian (Missourian) Tinajas Member of the Atrasado Formation, Central New Mexico. New Mexico Museum of Natural History and Science, Bulletin, 84: 391-424
New genus: Dracopristis
New species: Dracopristis hoffmanorum
Abstract: Two species of ctenacanthiform sharks are presently recognized at the Late Pennsylvanian (Missiourian) Kinney Brick Quarry Lagerstätte in the Manzanita Mountains east of Albuquerque New Mexico. A few isolated teeth of Glikmanius occidentalis have been collected from the quarry over a number of years and represent a large though rare ctenacanth in the Kinney Brick Quarry vertebrate assemblage. Dracopristis hoffmanorum gen et sp. nov is a new Pennsylvanian ctenacanth taxon and represents the most complete ctenacanth found in North America. The morphology of Dracopristis hoffmanorum suggests it specialized in benthic environmental conditions as a slow moving ambush predator in the shallow estuary/lagoon of Kinney Brick Quarry locality. Morphological data from Dracopristis hoffmanorum gen et sp. nov. and a review of the more complete ctenacanth taxa provided new information for cladistics analysis suggesting that Dracopristis hoffmanorum gen et sp. nov and other ctenacanths form a monophyletic group with a close sister relationship to Euselachii and were not members of the Cladodontomorphi.
LAURITO, C.A. & VALERIO, A.L. (2021): Revisión del estatus taxonómico de los Batomorphii fósiles de la cuenca Limón Sur, Costa Rica y descripción de una nueva especie de Dasyatidae. [Review of the taxonomic status of fossil Batomorphii from Southern Limon Basin, Costa Rica and description of a new species of Dasyatidae]. Revista Geológica de América Central, 65: 1-27
New species: Taeniurops sergiomorai
Abstract: A taxonomic review of the rays [Batoidea] faunal assemblage from the Locality of Alto Guayacán, initially described by Laurito (1999), was made, same that was recovered from sediments of the Uscari Formation. The reason for making such revision is the remarkable advance in the knowledge of the dentition and the phylogenetic relationships of the recent and fossil rays. This is complemented by the multiple investigations on fossil Chondrichthyes from southern Central America and the Caribbean that have undoubtedly revolutionized the fossil record of the region. Many of the new species, then described for the Southern Limón Basin, have been validated and recognized by the scientific community and registered in other locations. However, it was necessary to review some of the previous determinations, in order to have an updated taxonomic record.

New genus: Scyliorhinocotyle
New species: Leptomicrobothrium holohalaelure, Scyliorhinocotyle narvaezae
Abstract: The catshark genus Holohalaelurus Fowler is currently represented by five species distributed off the southern and eastern parts of the African coast. Very few parasitological records exist for any of these five species, representing a significant knowledge gap. We report the first monogenean species from the bathydemersal species Holohalaelurus regani (Gilchrist): a new species of Microbothriidae Price, 1936, Leptomicrobothrium holohalaelure n. sp. from the dorsal skin surface, and a new species of Hexabothriidae Price, 1942 representing a new genus, Scyliorhinocotyle narvaezae n. gen., n. sp., from the gill lamellae. Both monogenean records represent the first for any member of the catshark genus Holohalaelurus. Previously we focused on the identification of monogenean taxa of emerging veterinary importance for public aquaria. We now begin a focused effort to document a generally unexplored monogenean biodiversity from diverse marine habitats off South Africa.

Unexpected presence of great white sharks in Gulf of California
- Date: April 21, 2021
- Source: University of Delaware
- Summary: A new study suggests the white shark population for the eastern north Pacific, especially those listed in the Gulf of California, might be underestimated. Researchers found that the mortality rates for these white sharks might be underestimated as well, as an illicit fishery for the species was uncovered in the Gulf of California, suggesting that fishers were killing many more white sharks than has been previously understood.

Sharks use Earth's magnetic fields to guide them like a map
- Date: May 6, 2021
- Source: Cell Press
- Summary: Sea turtles are known for relying on magnetic signatures to find their way across thousands of miles to the very beaches where they hatched. Now, researchers have some of the first solid evidence that sharks also rely on magnetic fields for their long-distance forays across the sea.
