A new trigonotarbid arachnid, Gigantocharinus szatmaryi new genus and species, is described from Upper Devonian (Late Famennian) sediments in Pennsylvania. Devonian trigonotarbids were known before from only a single North American locality and several European ones. The new trigonotarbid occurs in what had previously been a significant time gap between the faunas of the Middle Devonian and the late Carboniferous. Gigantocharinus szatmaryi is assigned with some hesitation to the family Palaeocharinidae.

Speleopsobius weaveri, n. gen., n. sp., is described from lava tubes in southern Idaho, USA. The new taxon, and species of the genera Buethobius Chamberlin, 1911 and its probable synonym Yobius Chamberlin, 1945, are members of the family Anopsobiidae, not previously reported from North America. All known species of Henicopidae and Anopsobiidae from North America north of México are listed and briefly noted, along with all known anopsobiids from the northern hemisphere. Anopsobiella dawidoffi Attems, 1938 (Vietnam) is likely not a member of the family Anopsobiidae.

Mayachernes maatiatus, a new genus and species of pseudoscorpion of the family Chernetidae (Arachnida: Pseudoscorpionida), is described from the Miocene Chiapas – Amber Lagerstätte, south of Mexico. This new fossil species represents an adult male specimen with hard–soft tissues preserved in great detail. It differs from all other living chernetids by a combination of diagnostic characters. Anatomical data were collected using high-resolution microscopy with regular to infrared-reflected light. Mayachernes maatiatus is the first newly described fossil species of pseudoscorpion from the Chiapas amber. This taxon also adds to knowledge of the Chernetidae diversity in the southernmost part of North America at the Neogene.

Devonian Extinction

A crinoid and stelleroid fauna is described from the Famennian (Late Devonian) Broken Rib Member of the Dyer Formation of the White River Plateau, Colorado. The fauna postdates the Late Devonian extinction event. Six new crinoid species described, including the new genusTarassocrinus, are:Strimplecrinus dyerensis, Catactocrinus?torus, Hypselocrinus?bisonensis, Gilmocrinus?albus, Eireocrinus?coloradoensis, andTarassocrinus synchlydus.The cladid-dominated crinoid fauna is transitional between earlier Devonian and later Carboniferous faunas. It contains the first report ofCupressocrinites(a Famennian Lazarus taxon) andEireocrinus? in North America and extends ranges of several Carboniferous genera into the Late Devonian. A preliminary revision of the Rhenocrinidae is recommended. The family Glossocrinidae is recognized, and the Cupressocrinitidae are transferred to the Gasterocomacea.A new stelleroid genus and species,Pleiadeaster inceptus(Asteroidea; family unknown), and an ophiuroid,Ophiopolytretus aethus(Ophiuroidea; Lapworthuridae?) are named. In addition,Hudsonaster(Hudsonasteridae; Asteroidea) and two unassigned asteroids are present, and three further stelleroids cannot be assigned to the class level.PleiadeasterandHudsonasterare important because they suggest that the Late Devonian might have been a time of transition for asteroids.Ophiopolytretus aethusis an oegophiurid ophiuroid with distinctive respiratory? pores penetrating the disk plates.

The cladid crinoid order Poteriocrinida Jaekel, 1918 is a polyphyletic group that includes a variety of independent lineages united solely by the presence of ramulate or pinnulate arms. One of these lineages is the Rutkowskicrinidae new family herein assigned to the order Dendrocrinida, Bather 1899. Genera assigned to this new family include Rutkowskicrinus new genus, Decorocrinus new genus, Iteacrinus, Nassoviocrinus, Quantoxocrinus, Sacrinus, Sostronocrinus, ?Propoteriocrinus, and ?Schmidtocrinus. Members of this family are characterized by low conical cups with ridged thecal plates, U-shaped peneplenary radial facets bearing faint transverse ridges, a proximal median ridge on the posterior side of a long, narrow, predominantly straight anal sac, and pentagonal columns with one to two cirri per nodal. Arms in this family are highly variable, ranging from isotomous to heterotomous and pinnulate. The arms in the type specimen of Rutkowskicrinus patriciae n. sp. preserve all these various arm stages. The oldest presently known rutkowskicrinids occur in the Late Silurian (Ludlovian) of Australia and the Early Devonian (Pragian) of western Europe. The family diversified during the Middle Devonian (Givetian) in northeastern North America, and declined in numbers and diversity throughout the Late Devonian before going extinct in the Early Mississippian (Tournaisian).The Glossocrinidae Goldring, 1923, containing Glossocrinus, Charientocrinus, Catactocrinus, and Liparocrinus, is also reviewed. This family, distinguished by a strongly recumbent anal sac in the B-E plane and a prominent median ridge extending the entire length of the anal sac, was derived from the Rutkowskicrinidae during the Middle Devonian (Givetian) and diversified in the Late Devonian before going extinct at the Frasnian-Famennian boundary.The previously described rutkowskicrinid and glossocrinid genera listed above were assigned by Moore et al. (1978) to the dendrocrinid family Mastigocrinidae and poteriocrinid families Rhenocrinidae, Poteriocrinitidae, and Scytalocrinidae. Studied taxa include Rutkowskicrinus patriciae new genus and species, Rutkowskicrinus collieri new genus and species, Nassoviocrinus costatus (Goldring, 1954) new combination, Nassoviocrinus schultzei (Haarmann, 1921) new combination, Nassoviocrinus? duluki (Kesling, 1969) new combination, Nassoviocrinus? ornatus (Goldring, 1954) new combination, Nassoviocrinus? chilmanae new species, Decorocrinus arkonensis (Goldring, 1950) new combination, Decorocrinus cooperi (Goldring, 1926) new combination, Quantoxocrinus clarkei (Williams, 1882) new combination, Glossocrinus halli (Goldring, 1923) new combination, and Charientocrinus bellitubatus (Kesling, 1973) new combination.

Two new genera of the Chonostrophiidae are proposed herein to accommodate the resupinate shells from the Famennian sediments of the Late Devonian in the Santanghu Basin of the Balikun area, Xinjiang Province, northwestern China. Santanghuia santanghuensis new genus and species is distinguishable from other chonostrophiids by the possession of a pair of long dorsal anderidia and absence of a dorsal median septum. Balikunochonetes liaoi new genus and species is distinct because of the presence of a pair of anderidia with secondary anderidia, and a dorsal median septum. Santanghuia new genus is considered to be phylogenetically related to Chonostrophia of late Early to Middle Devonian age, while Balikunochonetes has possibly given rise to Chonostrophiella of Early Devonian age and is a likely ancestor of Tulcumbella of Early Carboniferous age.

A single specimen of a shrimp-like crustacean,Devonostenopus pennsylvaniensis, new genus and species is described from the Huntley Mountain Formation, which is Devonian–Carboniferous (Mississippian) in age. The specimen was collected in north-central Pennsylvania.Devonostenopus pennsylvaniensisis attributed to Stenopodidae. Co-occurrence of the specimen with pinnules ofArchaeopteris hallianaGoeppert, 1852, suggests that it is Devonian in age. Occurrence of a stenopodidean in the Devonian of North America is significant, as only three definitive decapods have been previously described from the Paleozoic and only two have been described from the Devonian. The earliest stenopodideans described to date are Cretaceous (Cenomanian and Santonian) in age. As such,Devonostenopus pennsylvaniensisextends the geologic range of Stenopodidea from Cretaceous to Late Devonian. Occurrence of a stenopodidean in the Devonian of North America, as well as the occurrence of the only two other known Devonian decapods in North America, suggests that Laurentia might have been a major area of endemism for Devonian decapods.

AbstractA new genus and species of the Elcanidae (Orthoptera, Elcanoidea), Cascadelcana virginiana n. gen. n. sp., is described based on a forewing specimen from the Upper Triassic (Norian) Cow Branch Formation in the Solite Quarry Lagerstätte near the North Carolina-Virginia boundary, USA. It is distinguished from other elcanid species by its RP+MA1 with six branches, M with two branches before stem MA1 fused with RP, and short CuA almost vertical against the posterior margin. This fossil represents the earliest definitive record of the family Elcanidae and the first orthopteran described from the Triassic of North America. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) analyses show that the veins and a pterostigma-like structure on the wing of C. virginiana n. gen. n. sp. are preserved as carbonaceous compressions. The presence of a pterostigma-like structure in elcanids indicates that they may have evolved a particular flight mechanism distinct from those of other orthopterans.UUID: http://zoobank.org/49526c99-5da4-48e3-ba6e-7018b8f9b1ae

Orthopteroid Insects

The Carboniferous was a period of high diversification of the polyneopteran insects of the superorder Archaeorthoptera (so-called ‘orthopteroid’ insects) (see Fossilworks site at http://fossilworks.org/bridge.pl?a=home). Some of the Late Carboniferous outcrops are very rich (Mazon Creek in North America, Commentry in France). The Konservat-Lagerstätte of Avion (Northern France) is especially rich for a Moscovian outcrop, with no less than six described genera and species: Aviogramma gracilis Prokop et al., 2014, Aviocladus pectinatus Prokop et al., 2014, Aviohapaloptera bethouxi Prokop et al., 2014, Aviologus duquesnei Coty et al., 2014, Cacurgus avionensis Schubnel et al., 2020, and cf. Tococladus sp. (Coty et al., 2014; Prokop et al., 2014; Schubnel et al., 2020). Here we describe a new genus and species, the first representative of the Carboniferous family Eoblattidae Handlirsch, 1906 from this outcrop, on the basis of a forewing.

Horseshoeichthys armaserratus , gen. et sp. nov., (Clupeomorpha: Ellimmichthyiformes: Sorbinichthyidae) is described from the Horseshoe Canyon Formation (Maastrichtian), Albertosaurus bonebed locality, Alberta, Canada. Horseshoeichthys armaserratus is classified as an ellimmichthyiform based on the following characters: the presence of a sixth infraorbital with a sensory canal that leads to the fifth infraorbital, absence of a supraorbital bone, subrectangular predorsal scutes, parietals in contact with each other at the midline, and two supramaxillae. The specimen is classified in the Sorbinichthyidae Family as it has abdominal ribs articulating in pits on the centra, posterior spines on predorsal scutes, and absence of a median spine on predorsal scutes. A new genus and species is proposed based on the presence of (anteriorly) Y-shaped mesethmoid, supraorbital, subrectangular predorsal scutes with coarse, rounded serrae on the posterior margin and a large anterior projection, scales with serrae on the circuli, and two postcleithra. This specimen represents the first freshwater ellimmichthyiform from the Upper Cretaceous of North America and the highest paleolatitude (59°N) occurrence known for the family. Furthermore, the dentary and centra have distinctive morphologies that are matched by specimens in microvertebrate localities from three underlying formations, including the Milk River Formation (Santonian), which indicates at least a 14 million year history for this lineage.
