ESEB is delighted to welcome you to the Second Joint Congress on Evolutionary Biology. Joint Congresses take place every six years and bring together four of the world's largest academic societies in the field of evolutionary biology: the European Society for Evolutionary Biology, the American Society of Naturalists, the Society for the Study of Evolution and the Society of Systematic Biologists. The first joint congress was in Ottawa, Canada in 2012. The current (i.e. second) will be held in Montpellier, France, on August 19-22 2018.
Save the date! 25. - 29. March 2019
The Mexican Society of Cartilaginous Fishes A.C., in coordination with the Planetarium of Playa del Carmen SAYAB, invites to participate in the First Latin American Conference of Sharks, Rays and Chimaeras, and the VIII National Symposium of Sharks and Rays.
5th International Whale Shark Conference (IWSC5) from 28-31 May 2019
From 28-31 May 2019, the town of Exmouth in the Ningaloo Coast World Heritage Area will welcome delegates to the 5th International Whale Shark Conference (IWSC5), a meeting of the world’s leading whale shark scientists, conservationists, natural resource managers and tourism managers. This is the fifth such conference to be held, following on from the successful IWSC4 held in Doha, Qatar in 2016. This meeting is timed to showcase Ningaloo’s world’s best practice whale shark management program and will follow the Ningaloo Whaleshark Festival, an annual community event that celebrates these magnificent animals.
IWSC5 will bring together local scientists, researchers and postgraduate students to interact with international colleagues and collaborators to explore all aspects of whale shark biology and ecology and how this can translate to direct, on-ground conservation efforts. Delegates from around the world will be treated to four days of presentations, workshops, social functions and experiencing the world renowned Ningaloo whale shark tourism industry to forge new relationships and collaborations and debate ideas.
A core focus of IWSC5 will be bringing together end users of the science being presented, such as tourism managers, marine park managers and conservation groups. This will improve the uptake and application of research and help develop collaborations between research scientists and managers and industry.

|TAXONOMIC NEWS/ NEW SPECIES
VIANA, S.T.F.L. & DE CARVALHO, M.R. (2018): Squalus rancureli Fourmanoir, 1979, a new junior synonym of the blacktailed spurdog S. melanurus Fourmanoir, 1979, and updated diagnosis of S. bucephalus Last, Séret & Pogonoski, 2007 from New Caledonia (Squaliformes, Squalidae). Zoosystema, 40 (9): 159-177
New synonym: Squalus rancureli Fourmanoir, 1979, a new junior synonym of the blacktailed spurdog S. melanurus Fourmanoir, 1979
Abstract: Squalus rancureli Fourmanoir, 1979 and S. melanurus Fourmanoir, 1979 are deep-sea sharks described from off New Caledonia and Vanuatu. Morphological separation between them is limited to caudal fin coloration and a few morphometric characters. These two nominal species were described as new in more than one taxonomic account, thus requiring nomenclatural elucidation. Taxonomic complexity behind S. rancureli and S. melanurus has been disregarded and underestimated in previous studies, and indicated to rely on propagation of erroneous authorship and negligence of requirements from the International Code on Zoological Nomenclature for describing new taxa. Analysis of type material and topotypic specimens revealed congruency of external morphology, external measurements and meristic data, suggesting conspecificity. Squalus rancureli is herein considered a junior synonym of S. melanurus, and authorship of these nominal species is clarified. Differential diagnosis and redescription of S. melanurus and an updated diagnosis of S. bucephalus Last, Séret & Pogonoski, 2007 are also provided based on new material. Comparative examinations with other regional congeners support their validity and recognition of a third species provisionally identified as Squalus cf. montalbani. Squalus melanurus is easily distinguished from S. bucephalus Last, Séret & Pogonoski, 2007 by bearing a black caudal-fin lower lobe, snout conspicuously elongate, dermal denticles tricuspidate, and smaller number of vertebrae (vs whitish caudal-fin lower lobe, snout conspicuously short, dermal denticles unicuspidate, higher number of vertebrae).

New genus: Caucasochasma
New species: Caucasochasma zherikhini
Abstract: Based on an almost complete impression from the base of the Pshekha Horizon (layer 2, Planorbella Beds, zone NP 21) of the North Caucasus (lower early Oligocene), we describe the basking shark Caucasochasma zherikhini gen. et sp. nov., differing from other members of family Cetorhinidae by higher number of vertebrae, weakly developed lower lobe of caudal fin, and details of the structure of gill rakers. Based on the structure of the body, it is not excluded that the described taxon was associated with the bottom to a greater degree than other species of the family (Keasius parvus and C. maximus), for which the structure of the body is known. The accumulations of plankton at the bottom could be a possible food resource for Caucasochasma.
SCHAEFFNER, B.C. & MARQUES, F.P.L. (2018): Integrative taxonomy unravels the species diversity of Parachristianella (Cestoda : Trypanorhyncha) from both sides of the Panamanian isthmus. Invertebrate Systematics, 32 (2): 278-318
New species: Parachristianella mendozai, Parachristianella kuchtai, Parachristianella campbelli, Parachristianella soldanovae, Parachristianella dollfusi
Abstract: The uplift of the Panamanian isthmus in the Pliocene caused the termination of gene flow among members of many ancestral populations of marine lineages leading the diversification of geminate species confined to opposite sides of Central America. This palaeogeographical event has been evoked to explain the diversification of few lineages of batoids with trans-isthmian distribution. As such, there is the expectation that this vicariance event also affected lineages of parasites associated with them. Our study suggests that this event can explain the diversification of ParachristianellaDollfus, 1946 (Trypanorhyncha : Eutetrarhynchidae) in the Caribbean Sea and tropical eastern Pacific Ocean. We provide molecular, morphological and biogeographical evidence to recognise five lineages within this genus inhabiting the coastal waters of Panama, including P. parva Campbell & Beveridge, 2007 and four new species: P. mendozai, sp. nov., P. kuchtai, sp. nov., P. campbelli, sp. nov. and P. soldanovae, sp. nov. These species can be diagnosed by unambiguous sets of molecular characters. The morphological cohesiveness of sister species, which most likely diverged from around 3 million years ago through the uplift of the Panamanian isthmus, suggests that the traditional emphasis on the tentacular armature to circumscribe species within trypanorhynchs might underestimate the diversity of recently diverged lineages.
QUITERIO-RENDON, G. & MONKS, S. & PULIDO-FLORES, G. (2018): Neonchocotyle violantei n. sp (Monogenea, Hexabothriidae) from Pseudobatos lentiginosus(Rhinopristiformes, Rhinobatidae) of Yucatan, Gulf of Mexico. Revista Brasileira De Parasitologia Veterinaria, 27 (1): 33-41
New species: Neonchocotyle violantei
Abstract: Neonchocotyle violantei n. sp. (Monogenea: Hexabothriidae) infects the gill of the Atlantic guitarfish, Pseudobatos lentiginosus (Rhinopristiformes, Rhinobatidae) from littoral waters of Celestun, Yucatan, Mexico. It is assigned to Neonchocotyle because it has, among other features, an asymmetrical haptor, a seminal receptacle, a smooth ootype, and an egg with two elongate filaments. It differs from Neonchocotyle pastinacae, the only congener, by having a small body (821 long by 315 wide, length to width = 2.6:1), two pairs of microhooks between the haptoral appendix suckers, extracaecal (submarginal) vaginal pores, and 5-9 testes. This is the first record of a species of Neonchocotyle in the Gulf of Mexico, the first monogenean reported from P. lentiginosus in Mexico and the second species of Hexabothriidae reported from Mexico.
RODRIGUEZ-IBARRA, E. & PULIDO-FLORES, G. & VIOLANTE-GONZALEZ, J. & MONKS, S. (2018): A new species of Acanthobothrium (Eucestoda: Onchobothriidae) in Aetobatus cf. narinari (Myliobatidae) from Campeche, Mexico. Revista Brasileira De Parasitologia Veterinaria, 27 (1): 67-74
New species: Acanthobothrium marquesi
Abstract: The helminthological examination of nine individuals of Aetobatus cf. narinari (spotted eagle ray; raya pinta; arraia pintada) revealed the presence of an undescribed species of cestode of the genus Acanthobothrium. The stingrays were collected from four locations in México: Laguna Términos, south of Isla del Carmen and the marine waters north of Isla del Carmen and Champotón, in the State of Campeche, and Isla Holbox, State of Quintana Roo. The new species, nominated Acanthobothrium marquesi, is a category 3 species (i.e, the strobila is long, has more than 50 proglottids, the numerous testicles greater than 80, and has asymmetrically-lobed ovaries); at the present, the only category 3 species that has been reported in the Western Atlantic Ocean is Acanthobothrium tortum. Acanthobothrium marquesi n. sp. can be distinguished from A. tortum by length (26.1 cm vs. 10.6 cm), greater number of proglottids (1,549 vs. 656), a larger scolex (707 μm long by 872 μm wide vs. 699 μm long by 665 μm wide), larger bothridia (626 μm long by 274 μm wide vs. 563 μm long by 238 μm wide). This is the first report of a species of Acanthobothrium from the Mexican coast of the Gulf México.

Potamotrygonidae constitute a unique and diversified family of South American freshwater stingrays grouping two subfamilies, the Potamotrygoninae and the Styracurinae, of which only the first group contains exclusively freshwater species. About 30 species occur in almost all river basins in South America, with the exception of the western basins of the Andes and the São Francisco River Complex.
Potamotrygoninae are grouped according to 4 genera: Potamotrygon Garman 1877 (30 species), Paratrygon Dumeril, 1865 (1 species), Plesiotrygon Rosa, Castello and Thorson, 1987 (2 species) and Heliotrygon Carvalho & Lovejoy (2 species), and are characterized by a rounded disc, a tail with a venomous sting, the pelvic girdle skeleton extending anteriorly through a long process, the reduction of the rectal gland and bright colors. They also have a very specific skin coating consisting of denticles and, depending on the species, thorny tubercles and bucklers.
Studying for almost 30 years the dermal covering of cartilaginous fish, I decided to develop the project Potamodontods 2018, in order 1) to study the morphological variations and characteristics of the dermal covering of Potamotrygoninae and 2) to use them in the systematics of this group because of their inter- and intra-specific morphological variations depending mainly on their location on the body and variations linked to growing stages.
Depending on a multidisciplinary team based in France and Brazil, the study will focus on the macro- and microscopic examination of the different species at different stages of development in order to clarify the systematics of that group and to know if morphological and distribution variations exist to separate species. A comparison with the sister group of Styracurinae will also be performed.
