Upcoming Meetings:




The 2nd Palaeontological Virtual Congress will be organized in a number of general theme sessions trying to span the whole variety of potential contributions.

However, Palaeontology is a wide discipline which encompasses a huge variety of topics.  Aware of this and taking advantage of the flexibility that virtual platforms offer, sessions proposals on emerging topics, innovative techniques or any other matter that you consider of interest are welcome to be addressed in depth during the celebration of the congress.

The purpose of such sessions is to provide a comprehensive forum for the exchange of ideas and discuss the issue within specialists in the target field.

If you are interested in proposing a specific session, please send us a brief description (no more than 300 words) with the main goals and any relevant information that you may consider relevant. Please, indicate in the proposal the full name of the organisers and their respective affiliations.

Proposals should be submitted by email to palaeovc@gmail.com before December 31st. Notification of acceptance will be sent to the organizers after that.  This edition, we want try to involve more to the participants, so if your workshop is accepted, the proposed organisers will be in charge of: 

– Look for contributions. Ideally, a single session would require the participation of at least 5 contributions, but this is only a suggestion and it is not mandatory.

– Send the abstracts to peer-review

– Moderating the sessions. We want to encourage a dialogue with all the participants, so the sessions organisers will be in charge of moderating and promoting debates in the discussion chats.



The 6th International Marine Conservation Congress

To conserve the world’s oceans we must go beyond science and use it to inform policy and management to catalyze change. The International Marine Conservation Congress (IMCC) brings together conservation professionals and students to develop new and powerful tools to further marine conservation science and policy.

With over 700 marine conservation professionals and students in attendance, IMCC is the most important international event for anyone involved or interested in marine conservation. The meeting brings together marine conservationists from many walks of life including but not limited to scientists, practitioners, educators, policy-makers, artists and journalists.

Extant Chondrichthyes:

 (2020): Revision of the sixgill sawsharks, genus Pliotrema (Chondrichthyes, Pristiophoriformes), with descriptions of two new species and a redescription of P. warreni Regan. PLoS ONE, 15 (3): e0228791
New species: Pliotrema kajae, Pliotrema annae
Abstract: Recent sampling efforts in Madagascar and Zanzibar, as well as examinations of six-gilled sawsharks in several museum collections provided evidence for a complex of species within Pliotrema warreni Regan. The present manuscript contains a redescription of Pwarreni involving the syntypes and additional material, as well as formal descriptions of two new species of Pliotrema Regan. All specimens of both new species were found in the western Indian Ocean. Individuals of the first new species, hereafter referred to as Pkajae sp. nov., were identified originating from Madagascar and the Mascarene Ridge. Specimens of the second new species, hereafter referred to as Pannae sp. nov., were only found off Zanzibar. Pliotrema kajae sp. nov. appears to inhabit upper insular slopes and submarine ridges at depths of 214–320 m, Pannae sp. nov. so far is only known from shallow waters (20–35 m). Both new species differ from Pwarreni in a number of characteristics including the known distribution range and fresh coloration. Taxonomical differences include barbels that are situated approximately half way from rostral tip to mouth, with prebarbel length equidistant from barbel origin to symphysis of the upper jaw in Pkajae sp. nov. and Pannae sp. nov. (vs. about two thirds way from rostral tip to mouth, with prebarbel length about twice the distance from barbel origin to symphysis of upper jaw in Pwarreni) and rostra that are clearly and slightly constricted between barbel origin and nostrils, respectively (vs. rostrum not constricted). Pliotrema kajae sp. nov. differs from Pannae sp. nov. in a longer snout, more numerous large lateral rostral teeth and upper jaw tooth rows, jaw teeth with (vs. without) sharp basal folds, and coloration, particularly pale to light brown (vs. medium to dark brown) dorsal coloration with (vs. without) two indistinct yellowish stripes. A revised diagnosis of Pliotrema and a key to the species are provided.

GANJGAH, N.M. & HASELI, M. (2020): A New Onchoproteocephalidean Cestode Species from the Spot-Tail Shark, Carcharhinus sorrah (Muller et Henle), in the Persian Gulf. Acta Parasitologica, in press
New species: Phoreiobothrium sorrahcola
Members of the onchoproteocephalidean genus Phoreiobothrium Linton, 1889 infect carcharhinid and sphyrnid sharks. Although the Persian Gulf harbors a rich fauna of sharks, the taxonomic diversity of Phoreiobothrium in this region has been explored little. A new species of Phoreiobothrium is herein described from Carcharhinus sorrah (Müller et Henle) off southern Iran.
Cestodes were isolated from the spiral intestine of Carcharhinus sorrah, fixed in 10% seawater-buffered formalin, and stored in 70% ethanol. For morphological examinations, worms were stained using acetic carmine; a subset was prepared for SEM.
Phoreiobothrium sorrahcola n. sp. is the first record of the genus from Csorrah and most closely resembles Phoreiobothrium rozatii Alijanpour Darvishi et Haseli, 2019 recently described from the Gulf of Oman. However, it differs from Prozatii in its possession of the rectangular, rather than triangular, bothridia, a longer cephalic peduncle (878–1300 vs 466–841), the longer axial prongs of lateral and medial hooks (B 56–80 vs 43–52; B’ 66–98 vs 46–62), and a greater maximum width of worm at level of scolex (302–415 vs 215–298).
With the description of this new species, three species of Phoreiobothrium have been reported so far from the southern waters of Iran. Phoreiobothrium now includes 17 valid species infecting 16 shark species.
CHERO, J.D. & CRUCES, C.L. & SAEZ, G. & SANTOS, C.P. & LUQUE, J.L. (2020): A new species of Heterocotyle (Monogenea: Monocotylidae), a gill parasite of the diamond stingray Hypanus dipterurus (Myliobatiformes: Dasyatidae) from the Peruvian coastal zone. Acta Parasitologica, in press
New species: Heterocotyle margaritae
A new monogenean, Heterocotyle margaritae n. sp. (Monocotylidae: Heterocotylinae), is described based on specimens collected from the gills of the diamond stingray, Hypanus dipterurus (Jordan & Gilbert, 1880) (Myliobatiformes: Dasyatidae) captured off the South Pacific coast, Lima Region, Peru.
Materials and methods
Monogeneans were fixed in hot 4% formalin, observed and measured as permanent mounts stained with Gomori’s trichrome, and mounted in Canada balsam. Drawings were made with the aid of a drawing tube.
The new species is distinguished from all congeners mainly by having a funnel-shaped male copulatory organ, spatulate distally with lateral folds and by its club-shaped accessory piece. The most similar congener, Hamericana Hargis, 1955, resemble Hmargaritae n. sp. regarding the general structure of the male copulatory organ (funnel-shaped with an accessory piece). However, besides other features, the new species differ from Hamericana by having an accessory piece without a dorsal button (vs an accessory piece with a dorsal button in Hamericana).
CAIRA, J.N. & JENSEN, K. & HAYES, C. & RUHNKE, T.R. (2020): Insights from new cestodes of the crocodile shark, Pseudocarcharias kamoharai (Lamniformes: Pseudocarchariidae), prompt expansion of Scyphyophyllidum and formal synonymization of seven phyllobothriidean genera - at last! Journal of Helminthology, 94: e132
New species: Scyphophyllidium timvickiorum, Clistobothrium amyae, Clistobothrium gabywalterorum
Abstract: Three new cestode species are described from the crocodile shark (Pseudocarcharias kamoharai) in Ecuador. All three were examined with light and scanning electron microscopy. The unique combination of morphological features in one of the new species prompted formal investigation of the non-monophyly of Paraorygmatobothrium relative to the morphologically similar genera DoliobothriumGuidusMarsupiobothriumNandocestus, OrectolobicestusRuhnkecestus and Scyphophyllidium. Sequence data generated for part of the 28S rDNA gene were subjected to maximum likelihood (ML) analysis. The resulting tree led to the synonymization of six of these seven genera with Scyphophyllidium, and transfer of their species to the latter genus. With the new species, the number of described members of Scyphophyllidium is now 45. The diagnosis of Scyphophyllidium is revised to accommodate these species. In addition, to expedite future descriptions, eight categories of Scyphophyllidium species are circumscribed, based largely on bothridial features. Scyphophyllidium timvickiorum n. sp. is a category 1 species. Beyond being the smallest category 1 species, it bears, rather than lacks, apical suckers and lacks, rather than bears, strobilar scutes. The two other new species are members of ClistobothriumClistobothrium amyae n. sp. differs from its congeners in bothridial shape, elongate cephalic peduncle and tiny size. Clistobothrium gabywalterorum n. sp. differs from the two of its congeners that also possess foliose bothridia in overall size and testis number. Despite their substantial morphological differences, the ML tree indicates they are sister taxa. Both are unique among their congeners in possessing cephalic peduncle spinitriches. The diagnosis of Clistobothrium is revised accordingly.
PALM, H.W. & MORALES-AVILA, J.R. & GALVAN-MAGANA, F. & HASELI, M.. (2020): A new genus and two new species of trypanorhynch cestodes (Tentaculariidae) from the sharks Carcharhinus sorrah (Müller & Henle) and Sphyrna lewini (Griffith & Smith) from off the coasts of Malaysia and Mexic. Systematic Parasitology, 97 (2): 133-142
New genus: Reimeriella
New species: Reimeriella varioacantha. Reimeriella mexicoensis
Abstract: Two new tentaculariid species were found infecting carcharhiniform sharks from off the coasts of Malaysian Borneo and the southwestern coast of the Baja California Sur, Mexico. Both new species exhibit a homeoacanthous heteromorphous basal and a homeoacanthous homeomorphous metabasal armature. Since this hook arrangement is unique within the tentaculariids and the taxonomy in this group deeply depends on the tentacular armature, Reimeriella n. g. is erected to accommodate Rvarioacantha n. sp. ex Carcharhinus sorrah (Müller & Henle) and Rmexicoensis n. sp. ex Sphyrna lewini (Griffith & Smith). Unlike Rmexicoensis n. sp., Rvarioacantha n. sp. has a pars bothrialis not overlapping the pars bulbosa and the number of testes is higher. Reimeriella mexicoensis n. sp. possesses very large uncinate to falcate hooks in the basal armature, while in Rvarioacantha n. sp. these hooks are almost the same in size as the remaining hooks in both the basal and metabasal armature. The latter species is the first tentaculariid species where the metabasal armature very closely resembles an eutetrarhynchid with a heteroacanthous typical homeomorphous metabasal armature and a high number of spiniform hooks per half spiral row (10–11 vs 6–7 in R. mexicoensis n. sp.) in the metabasal and apical armature. This pattern provides further morphological evidence for the close relationship of the Eutetrarhynchoidea and the Tentacularioidea. Reimeriella varioacantha n. sp. enriches the trypanorhynch fauna from off the coast of Malaysian Borneo while Rmexicoensis n. sp. is a novel record of a tentaculariid trypanorhynch from the Mexican Pacific.

TORRES-CARRERA, G. & RUIZ-ESCOBAR, F. & GARCÍA-PRIETO, L. & OCEGUERA-FIGUEROA, A. (2020): Narcinecotyle longifilamentus n. gen., n. sp. (Monogenea: Hexabothriidae), gill parasite of the numbfish Narcine entemedor (Torpediniformes: Narcinidae) from the Mexican Pacific coast. Parasitology International, in Press
New genus: Narcinecotyle
New species: Narcinecotyle longifilamentus
Abstract: A new genus and species of Hexabothriidae Price, 1942 is described from specimens infecting the gill of the numbfish Narcine entemedor Jordan and Starks from the Pacific coast of Mexico. In addition to the new taxon described here, species of 8 genera also display symmetrical haptors and have eggs with two polar filaments. However, they differ in the combination of the following features: distal portion of the male copulatory organ tubular, unarmed and proximally dilated confining an internal coiled duct, as well as dorsal origin of haptoral appendix. Based on molecular data derived from 3 loci, the mitochondrial Cytochrome C oxidase subunit 1 as well as the nuclear ribosomal 18S and 28S, the new species was found nested within Hexabothriidae together with the other 4 genera with representatives in GenBank. This is the first species of Hexabothriidae reported from a species of Narcinidae.
