Abstract: In this study we describe a new kitefin shark (Dalatiidae) genus and species Dracipinna bracheri gen. et sp. nov. based on upper Oligocene and lower Miocene tooth fossils. The teeth were excavated at three different sites which all lie in transgression phases. The fossil shark teeth are diverse and, depending on the excavation site, indicate pelagic to mesopelagic habitats. As these fossils were not found in older or younger sediments, we suggest a patchy distribution of the species. The fossils show several dental morphological characteristics of extant Dalatiidae. Phylogenetic analyses of combined morphological and DNA sequence-based data set suggest a weakly supported sister-group relationship of D. bracheri to extant Dalatiidae. Based on the dental morphological characters, we assign the dentition to a tearing type, which is rare among squaliform sharks and only known from a single extant species with a pelagic lifestyle.

Abstract: The sandpit near Rengetsweiler (Baden-Württemberg, SW Germany) is a famous locality for fossil shark and ray teeth from the Upper Marine Molasse (Lower Miocene). A total of 21 shark and ray genera were recovered from these sediments (Aetobatus, Alopias, Araloselachus, Carcharhinus, Carcharias, Carcharodon, Centrophorus, ?Dasyatis, Galeocerdo, Hemipristis, Isistius, Isurus, Mitsukurina, Notorynchus, Otodus (Megaselachus), Pachyscyllium, Physogaleus, Pseudocarcharias, Rhizoprionodon, Squatina, ?Triakis) as well as four specimens determinable as cf. Dasyatidae. The genera Araloselachus, Carcharoides, Otodus (Megaselachus), Pachyscyllium, and Physogaleus are extinct; all other taxa have living relatives. Based on extant representatives, the lifestyles of the ancient elasmobranchs range from a bottom-dwelling ambush predator (Squatina) to active swimming ones (Alopias, Carcharodon, Isurus, Otodus). Most of the taxa lived in the neritic realm. Members of Centrophorus, Isistius, Mitsukurina, and Pseudocarcharias are reconstructed as inhabitants of deeper water habitats. Based on Recent representatives and tooth shape, most of the taxa fed on invertebrates and/or fishes. Two taxa were dietary generalists (Galeocerdo, Notorynchus). Otodus fed on marine mammals. Carcharodon and adult Isurus also fed on marine mammals, in addition to fishes. Apart from the genera Centrophorus, Isistius, Mitsukurina, and Pseudocarcharias, the composition of the elasmobranch fauna as well as other fossil remnants and sedimentology indicate a fully marine, warm temperate and shallow water environment at the locality in the Lower Miocene. The normally deep-water taxa probably came occasionally into the shallow sea of Rengetsweiler.

 Scyliorhinus hachijoensis, a new species of catshark from the Izu Islands, Japan (Carcharhiniformes: Scyliorhinidae). Zootaxa, 5092(3), 331–349
New species: Scyliorhinus hachijoensis
Abstract: A new species of catshark genus Scyliorhinus, S. hachijoensis sp. nov., is described for the islands of Mikurajima, Hachijojima, and Torishima in southeastern Japan. Scyliorhinus hachijoensis has clasper hooks, which is a common feature in males of the most closely related species (S. torazame), but is distinguished by its coloration (presence of dark spots), the height of its anal fin (higher than the caudal peduncle), and the shape of pectoral and pelvic fins, and dermal denticles. Molecular data also corroborates the new species as a distinct and monophyletic taxon by nucleotide sequence analysis of three mitochondrial DNA regions.

The teeth were excavated at three different sites which all lie in transgression phases.

New species: Thaumastognathia bicorniger
Abstract: Gnathiid larvae (Crustacea; Isopoda; Gnathiidae) infesting elasmobranch and holocephalan fishes from mainly bathyal depths off Suruga Bay, off Kume-jima Island, and five sites from off Tokyo Bay to Shimoda City, Japan were examined. A total of 1460 gnathiid larvae were sampled from 87 host individuals belonging to seven families and 10 species. The morphology of these larvae was distinguishable from other gnathiid species by the head appendages. These larvae presented two pigmentation patterns, stripes or spots, on their dorsal thoraxes in live specimens. Furthermore, they were determined as the second and third stage praniza larvae on the basis of allometric variance of maximum head and abdomen widths. A third stage praniza with stripe pigmentation metamorphosed into an adult male and could be identified as a new species of the genus Thaumastognathia Monod, 1926. The duration between detachment from the host and metamorphosis into male adult required 204 days. This paper describes Thaumastognathia bicorniger sp. nov. on the basis of P3/stripe larvae and the male adult. This report is the first record of the larva and host information for a species of Thaumastognathia.
Javadi, L. & Haseli, M. (2022): Two New Cestode Species of Phoreiobothrium (Onchoproteocephalidea) from Two Carcharhinid Sharks of the Persian Gulf, with the First Report of Variation in Distribution of Vitelline Follicles of the Genus. Acta Parasitologica, in press
New species: Phoreiobothrium sarahae, Phoreiobothrium iraniense
Abstract: Purpose
The aim of this work was the morphological study of the onchoproteocephalidean cestodes from two shark species of the Persian Gulf.
Several specimens of Rhizoprionodon oligolinx, as well as of Carcharhinus dussumieri, were collected from the Persian Gulf, and the isolated cestodes from them were studied morphologically by light and scanning electron microscopy.
Phoreiobothrium sarahae n. sp. and Phoreiobothrium iraniense n. sp. were isolated, respectively, from Rhizoprionodon oligolinx Springer and Carcharhinus dussumieri (Müller & Henle). Both species are quite distinct from their congeners, except for Psorrahcola Masoumi Ganjgah & Haseli, 2020, in the distribution of the vitelline follicles (i.e., having more than two columns of vitelline follicles in each lateral band in the proglottids) and are distinguished from each other based on measurement, e.g., by the length of the cephalic peduncle, the width of the scolex at the level of hooks, and some measures related to the hooks. Phoreiobothrium iraniense n. sp. most closely resembles Psorrahcola, earlier described from Csorrah (Müller & Henle) from the Persian Gulf, with which it has an extensive overlap in the ranges of measurements and morphology. Nonetheless, it differs from Psorrahcola in the length of the cephalic peduncle and possessing, rather than lacking, the gladiate spinitriches on the proximal bothridial surfaces.
Along with the description of the two new species increasing the number of members of the genus in the Iranian coastal waters from three to five, for the first time a variation in distribution of the vitelline follicles is reported for Phoreiobothrium in this paper.
Van Der Spuy, L. & Smit, N.J. & Schaeffner, B.C. (2022): Threatened, host-specific affiliates of a red-listed host: Three new species of Acanthobothrium van Beneden, 1849 (Cestoda: Onchoproteocephalidea) from the endangered white skate, Rostroraja alba (Lacepede). International Journal for Parasitology: Parasites and Wildlife, 17, 114–126
New species: Acanthobothrium umbungus, Acanthobothrium usengozinius, Acanthobothrium ulondolozus
Abstract: The white skate, Rostroraja alba (Lacépède), is listed as an endangered species, the second-highest category before being declared extinct in the wild, in the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species. This species is heavily affected by anthropogenic impacts such as capture induced stress by overfishing and by-catch, habitat degradation and pollution that caused a drastic decline in populations in recent years. As part of a larger study on elasmobranch affiliates in southern Africa, two specimens of R. alba were screened. Three species of the tapeworm genus Acanthobothrium van Beneden, 1849 (Cestoda: Onchoproteocephalidea) were discovered. Application of Ghoshroy and Caira's classification system facilitated the differentiation of congeners through a combination of specific morphological characteristics. As a consequence, three species new to science are described herein, namely Acanthobothrium umbungus n. sp., Acanthobothrium usengozinius n. sp., and Acanthobothrium ulondolozus n. sp. In light of these new discoveries from an endangered host, it is apparent to address the conservation status of its affiliate species, that co-evolved with their elasmobranch hosts for millions of years, thereby creating unique and intimate host-parasite interrelationships. Currently, altering environmental conditions caused by anthropogenic pressures have direct impacts on this host-parasite system with increasing risks of extinction. As merely 9% of elasmobranchs in South African waters have been examined for endohelminths and other affiliate taxa, extensive studies on these organisms and their hosts implementing multisource approaches are needed. This will provide a better understanding on the intimate nature of host-parasite systems that may lead to new prospects in conservation science and the preservation of threatened host species, such as R. alba, together with their unique fauna of affiliate species.

New species: Anthobothrium parimae, Anthobothrium shayani, Anthobothrium samae
Abstract: The sampling of 22 specimens of Rhizoprionodon oligolinx Springer from the Persian Gulf made possible the description of three new species of Anthobothrium van Beneden, 1850. Anthobothrium parimae sp. nov. is different from its congeners, except for Aaltavelae Neifar, Euzet and Ben Hassine, 2002, Alyndoni Ruhnke and Caira, 2009, and Alesteri Williams, Burt and Caira, 2004, in the total length. It differs from Aaltavelae in the number of the proglottids; from Alyndoni in the length of the mature proglottids; and from Alesteri Williams, Burt and Caira, 2004 in possessing one hemicircular band, rather than two circular bands, of musculature in its bothridia. The other two new species, being the smallest in size within the genus, most closely resemble each other but differ in the position of the genital pore in the proglottid, the number of post-vaginal testes, the number of the ventral and dorsal columns of vitelline follicles in each lateral band, and the distribution of the gladiate spinitriches on the strobila. These three new species are the only “tetraphyllidean” species reported to date from the southern waters of Iran. In addition, for the first time, more than two congeners belonging to Anthobothrium are reported from the same host species sympatrically and simultaneously. The morphological variation within this genus is also discussed.
