Extinct Chondrichthyes:
Cicimurri, D.J. & Knight, J.L. & Ebersole, J.A. (2022): Early Oligocene (Rupelian) fishes (Chondrichthyes, Osteich- thyes) from the Ashley Formation (Cooper Group) of South Carolina, USA. PaleoBios, 39, 1–38
New species: Scyliorhinus weemsi
Abstract: Matrix surrounding a dermochelyid carapace and two cetacean skulls recovered from the Givhans Ferry Member of the Ashley Formation (lower Oligocene, Rupelian Stage) in South Carolina, USA yielded a surprisingly diverse assemblage of euselachian and teleost fishes. We identified 21 elasmobranch taxa, including 13 selachians and eight batoids, nearly all of which are known to occur in the overlying upper Oligocene (Chattian) Chandler Bridge Formation. Notable occurrences within the Ashley Formation paleofauna include a new shark, Scyliorhinus weemsi n. sp., and the first South Carolina Oligocene records of Squalus sp., Pristiophorus sp., and Pachyscyllium sp. Numerous teleost taxa were also documented based on isolated teeth, including species of Albulidae, Paralichthyidae, Osteoglossidae, Sparidae, Sciaenidae, Sphyraenidae, Scombridae, Trichiuridae, and possibly Labridae.

Lisnerova, M. & Lisner, A. & Cantatore, D.M.P. & Schaeffner, B.C. & Peckova, H. & Tyml, T. & Fiala, I. & Bartosova-Sojkova, P. & Holzer, A.S. (2022): Correlated evolution of fish host length and parasite spore size: a tale from myxosporeans inhabiting elasmobranchs. International Journal for Parasitology, 52, 97–110
New species: Ceratomyxa sigmoidea, Ceratomyxa barbini, Sphaerospora alata, Sphaerospora terraenovae, Sphaerospora argentinensis
Abstract: Myxozoa represent a diverse group of microscopic cnidarian endoparasites alternating between invertebrate and vertebrate hosts. Of the approximately 2,600 species described predominantly from teleost fish, only 1.8% have been reported from cartilaginous fishes (Elasmobranchii). As ancestral vertebrate hosts of myxozoans, elasmobranchs may have played an important role in myxozoan evolution, however, they are also some of the largest vertebrate hosts known for this group of parasites. We screened 50 elasmobranchs belonging to nine species and seven families, from various geographical areas, for myxozoan infection. We found a 22% overall prevalence of myxozoans in elasmobranchs and describe five species new to science. We investigated, for the first known time, the evolution of spore size within three phylogenetic clades, CeratomyxaSphaerospora sensu stricto and Parvicapsula. We found that spores from elasmobranch-infecting myxozoans were on average 4.8× (Ceratomyxa), 2.2× (Parvicapsula clade) and 1.8× (Sphaerospora sensu stricto except polysporoplasmic Sphaerospora spp.) larger than those from teleosts. In all analysed clades, spore size was correlated with phylogenetic position. In ceratomyxids, it was further strongly positively correlated with fish body size and habitat depth, independent of cellular composition of the spores and phylogenetic position in the tree. While in macroparasites a host size-correlated increase in parasite size occurs on a large scale and is often related to improved exploitation of host resources, in microscopic parasites size ranges vary at the scale of a few micrometres, disproportionate to the available additional space in a large host. We discuss the ecological role of these changes with regard to transmission under high pressure and an invertebrate fauna that is adapted to deeper marine habitats.
Ingelbrecht, J. & Morgan, D.L. & Lear, K.O. & Fazeldean, T. & Lymbery, A.J. & Norman, B.M. & Martin, S.B. (2022): A new microbothriid monogenean Dermopristis pterophilus n. sp. from the skin of the Critically Endangered green sawfish Pristis zijsron Bleeker, 1851 (Batoidea: Pristidae) in Western Australia. International Journal for Parasitology-Parasites and Wildlife, 17, 185–193
New species: Dermopristis pterophilus
Abstract: A new microbothriid monogenean Dermopristis pterophilus n. sp. is described from the skin of the Critically Endangered green sawfish Pristis zijsron Bleeker, 1851 in the Ashburton River delta, northern Western Australia. Analyses of the 28S ribosomal DNA marker and the molecular barcoding markers Histone 3 and Elongation Factor 1 α confirmed position among the Microbothriidae, with close affinity to the only other sequenced representative of Dermopristis Kearn, Whittington and Evans-Groing, 2010. The new species is morphologically consistent with the concept of Dermopristis; it has two testes, lacks a male copulatory organ and has a simple haptor. It is smaller than its two congeners Dparadoxus Kearn, Whittington and Evans-Gowing, 2010 and Dcairae Whittington and Kearn, 2011 and is most similar to the former, distinguished only in that it lacks the strong, transverse, parallel ridges on the ventral body surface that characterise that species. It is more easily distinguished from Dcairae, differing in body shape, possession of a seminal receptacle, and relative position and size of the haptor. It may further differ from both species by fine details of the gut diverticula, although these details are difficult to ascertain. Spermatophores were observed in the new species, similar to those previously reported for Dcairae. The new species exhibits site attachment preference: infections were greatest on and immediately adjacent to the host pelvic fins (including male reproductive organs, i.e. claspers), moderate in proximity to the dorsal and pectoral fins, few on the caudal fin and peduncle, and infrequently, isolated worms occurred elsewhere on the dorsal and ventral surfaces of the body. There was no incidence of infection on the head (including rostrum). We presume Dpterophilus is restricted to Pzijsron and thus likely faces the same threat of extinction.
Herzog, K.S. & Jensen, K. (2022): A synergistic, global approach to revising the trypanorhynch tapeworm family Rhinoptericolidae (Trypanobatoida). Peerj, 10, Article e12865
New species: Rhinoptericola hexacantha, Rhinoptericola mozambiquensis, Rhinoptericola schaeffneri
Abstract: Since 2010, the trypanorhynch tapeworm family Rhinoptericolidae Carvajal & Campbell, 1975 has housed just two distinctive, monotypic genera (Rhinoptericola Carvajal & Campbell, 1975 and Nataliella Palm, 2010). However, global collections of tapeworms from sharks and rays over the last more than three decades brought to light the need for major revision of the family by suggesting a much greater species-level diversity for the nominal genus Rhinoptericola. Through synonymy and the description of new species, the number of species in the genus is increased from one to eight. A phylogenetic analysis of the D1–D3 gene region of 28S rRNA (28S), including seven of the now nine species of rhinoptericolids, and a broad sampling of the other Trypanobatoida is the first to recover a monophyletic Rhinoptericolidae. In addition to systematic revision, this study allowed for the first evaluation of the degree of intraspecific vs interspecific variation in 28S for adult trypanorhynchs across the various hosts and geographic localities from which they have been reported, suggesting a relatively consistent boundary for Rhinoptericola. It is further suggested that detailed scanning electron microscopy (SEM) images of both the basal and metabasal armatures greatly aid in the interpretation of hook arrangement and shape. A schematic to streamline determination of the tentacular surface presented in scanning electron micrographs and line drawings of trypanorhynchs is presented for species with both two and four bothria. In combination, these methodological refinements can now be used as a model to resolve issues of classification and non-monophyly within both major lineages of the Trypanorhyncha. As a result of the taxonomic work, Rhinoptericola megacantha Carvajal & Campbell, 1975 (previously only known from the American cownose ray from the Chesapeake Bay and the Ticon cownose ray from the Gulf of Mexico, Venezuela, and Brazil) is now known from an additional species of cownose ray and a species of stingray, and is revealed to have a transatlantic distribution. Data from SEM suggest a simpler interpretation of hook arrangement in the metabasal armature for Rhinoptercola and—in combination with 28S sequence data—support Shirleyrhynchus Beveridge & Campbell, 1988 (a former rhinoptericolid) as its junior synonym. The three species formerly assigned to Shirleyrhynchus are thus transferred to Rhinoptericola. Data from light microscopy on whole-mounted specimens and histological sections, SEM, and 28S showed the eutetrarhynchid Prochristianella jensenae Schaeffner & Beveridge, 2012b to be morphologically consistent with species of Rhinoptericola and it is thus transferred to the genus. The type series of P. jensenae was determined to be mixed, representing two distinct species which are here redescribed and described as new, respectively. Two additional novel species of Rhinoptericola are described from cownose rays from off Mozambique and the Gulf of California.
