The genus Adelocoenia ORBIGNY, 1849, is revised and a neotype is designated for its type species Astrea castellum MICHELIN, 1844. For various reasons that lie in the taxonomic history of scleractinian corals, it has become a difficult task to reliably assign Mesozoic corals having the combined features of plocoid corallite integration and the absence of a columella. Therefore, many such genera are in need of revision, one of which is Adelocoenia. In addition to the revision of the type species, Jurassic species grouped within Adelocoenia are revised using type material when it was possible. Many new synonymies are proposed based mainly on characters such as symmetry and dimensions of skeletal features. Another consequence is that most species previously grouped with Pseudocoenia ORBIGNY are transferred to Adelocoenia. Furthermore, we present a clarified view of the paleogeographical and stratigraphical distributional patterns of the genus Adelocoenia, according to which Adelocoenia had its first appearance during the Early Jurassic, represented by a single specimen known from the Sinemurian of France. Subsequently, this genus had a significant increase in both distribution and diversity during the Middle Jurassic. The pinnacle of its success followed in the Late Jurassic during which Adelocoenia had its greatest morphological disparity and taxonomical diversity, and its largest geographical distribution. The genus survived in the Cretaceous record. Throughout its history, Adelocoenia predominantly occurred in inner platform environments that were located in low latitudes.

In this work, it is explained why previous authors who considered that Canthidium lentum Erichson, 1947 (Coleoptera: Scarabaeidae: Scarabaeinae) was fixed as the type species of Canthidium Erichson, 1847 in Robert Lucas’ 1920 catalogue of Coleoptera genera were mistaken. Instead, the first authors to designate a type species for Canthidium were Martínez et al. in 1964, who designated C. thalassinum Erichson, 1847. Since both species are currently placed in different subgenera, the subgeneric classication must change: Eucanthidium Halffter & Martínez, 1986 is a new junior synonym of Canthidium, while the subgenus previously considered to be Canthidium (Canthidium) is changed to Canthidium (Neocanthidium) Martínez et al., 1964 based on the revalidation of the latter name. A checklist containing information on the type locality, type material, synonymy, and distribution of all the 172 valid species included in the genus (72 in the nominotypical subgenus, 69 in Neocanthidium, and 31 as incertae sedis) is presented, as well as a review of the taxonomic history of Canthidium and the new synonymy between C. (C.) ardens Bates, 1887 and Canthidium ardens mutatum Bates, 1887.

Proteocephalid tapeworms (Cestoda) are one of the dominant groups of intestinal parasites of Neotropical catfishes (Siluriformes), especially pimelodids (de Chambrier et al. 2015). The long and convoluted taxonomic history of species of Chambriella Rego, Chubb & Pavanelli, 1999 has been disentangled only recently by Alves et al. (2017). These authors erected a new genus, Riggenbachiella Alves, de Chambrier, Luque & Scholz, 2017, to accommodate R. amazonense Alves, de Chambrier, Luque & Scholz, 2017 (type-species) and R. paranaense (Pavanelli & Rego, 1989) (previously Chambriella paranaensis), parasites of pimelodid catfishes.

The discovery of a new stem turtle from the Middle Jurassic (Bathonian) deposits of the Isle of Skye, Scotland, sheds new light on the early evolutionary history of Testudinata. Eileanchelys waldmani gen. et sp. nov. is known from cranial and postcranial material of several individuals and represents the most complete Middle Jurassic turtle described to date, bridging the morphological gap between basal turtles from the Late Triassic–Early Jurassic and crown-group turtles that diversify during the Late Jurassic. A phylogenetic analysis places the new taxon within the stem group of Testudines (crown-group turtles) and suggests a sister-group relationship between E. waldmani and Heckerochelys romani from the Middle Jurassic of Russia. Moreover, E. waldmani also demonstrates that stem turtles were ecologically diverse, as it may represent the earliest known aquatic turtle.

The Solnhofen Archipelago is well known for its fossil vertebrates of Late Jurassic age, among which figure numerous rhynchocephalian specimens, representing at least six and up to nine genera. A new taxon, named Sphenofontis velserae gen. et sp. nov., increases rhynchocephalian diversity in the Solnhofen Archipelago and is herein described based on a single, well-preserved specimen originating from the Late Kimmeridgian of the Brunn quarry, near Regensburg. The exquisite preservation of the holotype allowed a detailed description of the animal, revealing a skeletal morphology that includes both plesiomorphic and derived features within rhynchocephalians. Sphenofontis is herein referred to Neosphenodontia and tentatively to sphenodontine sphenodontids. It notably differs from all other rhynchocephalians known from the Jurassic of Europe, showing instead closer resemblance with the Middle Jurassic Cynosphenodon from Mexico and especially the extant Sphenodon. This is evidence for a wide distribution of taxa related to the extant tuatara early in the Mesozoic, and also for the presence of less-specialized rhynchocephalians coexisting with more derived forms during the earliest time in the history of the Solnhofen Archipelago.

Abstract —The Kolyvan’–Tomsk folded zone (KTFZ) is a late Permian collisional orogen in the northwestern section of the Central Asian Orogenic Belt. The Mesozoic history of the KTFZ area includes Late Triassic–Early Jurassic and Late Jurassic–Early Cretaceous orogenic events. The earlier event produced narrow deep half-ramp basins filled with Early–Middle Jurassic molasse south of the KTFZ, and the later activity rejuvenated the Tomsk thrust fault, whereby the KTFZ Paleozoic rocks were thrust over the Early–Middle Jurassic basin sediments. The Mesozoic orogenic events induced erosion and the ensuing exposure of granitoids (Barlak complex) that were emplaced in a within-plate context after the Permian collisional orogeny. Both events were most likely associated with ocean closure, i.e., the Paleothetys Ocean in the Late Triassic–Early Jurassic and the Mongol–Okhotsk Ocean in the Late Jurassic–Early Cretaceous. The apatite fission track (AFT) ages of granitoids from the Ob’ complex in the KTFZ range between ~120 and 100 Ma (the Aptian and the Albian). The rocks with Early Cretaceous AFT ages were exhumed as a result of denudation and peneplanation of the Early Cretaceous orogeny, which produced a vast Late Cretaceous–Paleogene planation surface. The tectonic pattern of the two orogenic events, although being different in details, generally inherited the late Paleozoic primary collisional structure of the Kolyvan’–Tomsk zone.

Broad Scale

Atoposaurids were a clade of semiaquatic crocodyliforms known from the Late Jurassic to the latest Cretaceous. Tentative remains from Europe, Morocco, and Madagascar may extend their range into the Middle Jurassic. Here we report the first unambiguous Middle Jurassic (late Bajocian–Bathonian) atoposaurid: an anterior dentary from the Isle of Skye, Scotland, UK. A comprehensive review of atoposaurid specimens demonstrates that this dentary can be referred to Theriosuchus based on several derived characters, and differs from the five previously recognized species within this genus. Despite several diagnostic features, we conservatively refer it to Theriosuchus sp., pending the discovery of more complete material. As the oldest known definitively diagnostic atoposaurid, this discovery indicates that the oldest members of this group were small-bodied, had heterodont dentition, and were most likely widespread components of European faunas. Our review of mandibular and dental features in atoposaurids not only allows us to present a revised diagnosis of Theriosuchus, but also reveals a great amount of variability within this genus, and indicates that there are currently five valid species that can be differentiated by unique combinations of dental characteristics. This variability can be included in future broad-scale cladistics analyses of atoposaurids and closely related crocodyliforms, which promise to help untangle the complicated taxonomy and evolutionary history of Atoposauridae.

Detailed Diagnosis

Mouse opossums of the genus Marmosa Gray (Didelphidae) represent a complex of taxa with poorly understood affinities. Species now placed within this genus are mostly the leftovers from previous taxonomic arrangements. Even the most recent and complete revisions have not fully resolved the relationships among Marmosa and the many taxa previously included in Marmosa or listed as synonyms of it. Herein, we review and discuss one of these taxa, Stegomarmosa, based on new specimens that significantly increase our knowledge of the morphological diversification of the group. Until recently, this genus/subgenus has been known only from a single specimen taken more than 50 years ago in southeastern Peru. In 1997-1998, six additional specimens were collected at two little-separated localities almost 200 km NW of the type locality. We include a detailed diagnosis of the genus-group Stegomarmosa and its type species, M. andersoni, and update the distribution for and provide new information on the natural history of the latter. We also discuss published claims, concerning geographic range, that may be inaccurate and misleading. Finally, we scored the morphological characters used in the most recent phylogenetic analyses of the didelphids, in order to explore the affinities of M. andersoni and to determine the distinctiveness of the taxon Stegomarmosa.

We studied the Neotropical genera Epanycles Butler, Sciopsyche Butler and Episcepsis Butler. We investigated the delimitation of Epanycles, which at the beginning of this work was monotypic, but had a history of other species placed in it, all of which are currently placed in genera to which they do not belong. Indeed, we found Epanycles to include only its type species, Euchromia imperialis Walker, here redescribed based on external and genitalic characters of both sexes from specimens covering most of its known geographical distribution. Our investigation included detailed studies of the species previously placed in Epanycles (Hyaleucerea gigantea (Druce) and Eucereon obscurum (Möschler)), and of species belonging to genera putatively closely related to it: Sciopsyche tropica (Walker), Episcepsis venata Butler, Episcepsis endodasia Hampson and Episcepsis luctuosa (Möschler). The characters separating all these taxa from Epanycles are discussed, and a mistake in the publication of Episcepsis atlantica Pinheiro & Araujo Jr. is corrected. The habitus and genitalia of the species herein treated are illustrated.

Complete History

In the first half of the nineteenth century, a marked shift occurred in our understanding and treatment of the chelicerate fossil record, with the differentiation and recognition of entirely extinct genera for the first time. At the heart of this taxonomic revolution were the Eurypterida (sea scorpions) and Xiphosura (horseshoe crabs), although both groups were in fact considered crustaceans until Lankester's (1881) seminal comparative anatomical study of the extant xiphosuran Limulus Müller, 1785 and modern scorpions. The oldest available eurypterid genus is Eurypterus deKay, 1825; the oldest available fossil arachnid genus name is that of the scorpion Cyclophthalmus Corda, 1835. However, there has been considerable historical confusion over the oldest available fossil xiphosuran genus name, which has been recognized alternately as Belinurus König (with a publication date of either 1820 or 1851) or the synonymous Bellinurus Pictet, 1846. Most recent treatments (e.g., Selden and Siveter, 1987; Anderson and Selden, 1997; Anderson et al., 1997; Lamsdell, 2016, 2021; Bicknell and Pates, 2020) have favored Bellinurus Pictet, 1846 as the available name; however, Haug and Haug (2020) recently argued that Belinurus König, 1820 is valid and has priority, a position then followed by Lamsdell (2020), prompting a reinvestigation of the taxonomic history of the genus. Upon review, it is clear that neither of the previously recognized authorities for Belinurus are accurate and that the two candidate type species for each genus are, in fact, synonyms. Given the convoluted and at times almost illogical history of the competing names, along with the most recent controversy as to which has priority, we present a complete history of the treatment of the genus to resolve the issue.

The nomenclatural and taxonomic history of Cassinia R.Br. is reviewed, particularly in relation to its close relative Ozothamnus R.Br. Current concepts of Ozothamnus are shown to be unsatisfactory, with that genus consisting of a 'core' of approximately 25 species (including the type species O.�rosmarinifolius R.Br.) which are defined by their possession of inner phyllaries with radiating tips and no paleae (or only very few) between the florets, and other characters. The other 25 species (approximate) of 'Ozothamnus' need re-examination and probable placement elsewhere (but not in Cassinia). Cassinia can be satisfactorily defined as a genus distinct from 'core' Ozothamnus. As a precursor to a series of papers describing the species of Cassinia (including a large number of new taxa), Cassinia is divided into two subgenera, seven sections and two series. New taxa described are Cassinia copensis Orchard, Cassinia subg. Achromolaena (Cass.) Orchard, Cassinia sect. Complanatae Orchard, Cassinia sect. Venustae Orchard, Cassinia sect. Leptocephalae Orchard, Cassinia sect. Costatae Orchard, Cassinia sect. Arcuatae Orchard, Cassinia (sect. Cassinia) ser. Cassinia and Cassinia (sect. Cassinia) ser. Longifoliae Orchard.
