A new palaeodictyopterid, Aviobreyeria gracilis gen.n., sp.n., is described from an outcrop of Upper Carboniferous (Westphalian C/D) deposits at Avion in the Nord-Pas-de-Calais department (France). This new taxon is placed in the family Breyeriidae based on a comparison of the pattern of venation in its forewing venation with that of other breyeriids and possibly related genera within the Breyerioidea. In addition, wings of different immature instars of palaeodictyopterids from the same strata with a similar pattern of venation but differing in having an enlarged RP and a broader anal area (supposed hind wings) were also tentatively attributed to Breyeriidae gen. et sp. indet.. These wings have a roughly identifiable venation and exhibit the gradual development of wings through different ontogenetic stages and their position on the thorax, which is sparsely documented for Paleozoic insects. Discovery of immature and adult stages of palaeodictyopterids in the same layers also indicates they lived in similar habitats.

A new asellotan isopod of the family Protojaniridae Fresi, Idato & Scipione, 1980 is described from freshwater springs in the Osorno province, Los Lagos region, southern Chile. Wiyufiloides osornoensis gen. & sp. n. is the third South American protojanirid species and the first known groundwater isopod in Chile. The new genus and species is principally characterized by the presence of a vestigial antennal scale, a strongly subchelate pereiopod I and the absence of an apical lobe on the protopod of pleopod II. The new taxon is described in detail and figures are given.

The Palaeozoic archaeorthopteran order Cnemidolestodea Handlirsch, 1937 (sensu Béthoux, 2005; not sensu Aristov, 2014) currently comprises only the family Cnemidolestidae Handlirsch, 1906. They are easily characterized by the presence of a more or less triangular area delimited by the vein MA and the first anterior fork of MP+CuA+CuPa, this last vein having several parallel posterior branches. Dvořák et al. (2021) listed the included genera, and described the new genus and species Piesbergopterum punctatum from the Moscovian of Piesberg (Germany), characterized by the presence of a pattern of rounded spots in numerous cells all over the forewings. Nel & Poschmann (in press) noticed that the Cnemidolestidae show an important diversity of patterns of coloration on their forewings, possibly related to cryptic behaviors in the vegetation.

A new genus is described to accommodate Neodicranella hamulosa, a novel species resolved in the family Aongstroemiaceae, from the Monchiquense district in SW Portugal. Characterized by its small size, erect spreading to subsecund non-sheathing leaves, plane bistratose leaf margins, and rhizoidal gemmae with slightly protruberant cells, it differs from all other European Dicranellaceae in the uniquely patterned distal peristome segments with backward-pointing papillae resembling hooked barbs. The species appears to be endemic to the sub-Mediterranean bioclimatic zone, in wooded biomes where humidity remains relatively high throughout the year. Morphological and molecular data strongly support the singularity of this new taxon. The species is illustrated by photomicrographs and SEM, and its ecology and conservation are discussed.

A new genus and species, Patagosmilus goini, of the family Thylacosmilidae (Mammalia, Metatheria, Sparassodonta) is described here. The new taxon is based on a single specimen collected from the west margin of the Río Chico, in Río Negro Province, Argentina, from the middle Miocene Colloncuran SALMA. Until now, two formally recognized species were encompassed in the family Thylacosmilidae: Thylacosmilus atrox, from the late Miocene-late Pliocene Huayquerian to Chapadmalalan SALMAof Argentina and probably Uruguay; and Anachlysictis gracilis, from the middle Miocene Laventan SALMA of Colombia. Recognition of the Patagonian taxon, Patagosmilus, provides new anatomical data, likely to be included in future phylogenetic analyses. The overall morphology of Patagosmilus suggests that it has a more generalized anatomy than Thylacosmilus. The dental morphology suggests the new Patagonian taxon was probably closer to Thylacosmilus than Anachlysictis. Saber-tooth thylacosmilids have several autapomorphic features in the skull that differentiate them from other sparassodonts, including the delayed replacement or non-replacement of the deciduous last premolar.

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.

Macroscopic fossils of terrestrial animals originating directly from deposits close to the Permian/Triassic boundary are very scarce. Volcanic ash sediments in Eastern Siberia were found to hold the cockroach Sobytie tungusicum gen. et sp. n. This new taxon belongs to the predominantly Palaeozoic family Phyloblattidae, but has many advanced features characteristic of the Mesozoic family Caloblattinidae, and also of the basal Liberiblattinidae. These connections provide an indication of the origin of the family Liberiblattinidae and thus all the Mesozoic cockroach lineages from such Phyloblattidae – precursors of the Caloblattinidae.

AbstractA new genus and species of primitive-limbed mosasauroid, Dallasaurus turneri, from the Middle Turonian (∼92 Ma) of north-central Texas, is described on the basis of two incomplete skeletons. The new taxon retains plesiomorphic characters such as facultatively terrestrial limbs (plesiopedal) but also exhibits certain characters shared with derived mosasaurs of the subfamily Mosasaurinae. In phylogenetic analysis, the new taxon reconstructs as the basal member of that clade. Other plesiopedal taxa previously included in the family Aigialosauridae reconstruct in basal positions within three different, major clades that include members that achieved the derived (hydropedal) fin-like limb condition. In addition, Opetiosaurus and Aigialosaurus reconstruct as successive outgroup taxa to all other mosasauroids, thereby demonstrating the paraphyletic nature of the current concept of Aigialosauridae. Interpretation of our phylogenetic analysis suggests that three different lineages of mosasauroids independently achieved the derived mosasaur body plan, including fully marine limb modifications culminating in the development of flippers or paddle-like appendages. The inclusion of plesiopedal forms within lineages of well-established hydropedal clades requires a reorganisation of our concepts of Mosasauridae to include these basal forms. In order to avoid continued use of the paraphyletic taxon ‘Aigialosauridae’ as currently defined, we recommend ‘Aigialosauridae’ as a formal taxonomic name be used only for inclusion of Aigialosaurus dalmaticus and potential members of its own independent lineage. This also avoids the implicit polyphyletic use of ‘Mosasauridae’. Additionally, the diagnosis of Mosasauridae should be modified to exclude limb characters that discriminate between more terrestrial versus more aquatic adaptations.

Mazon Creek

The family Syntonopteridae was named by Handlirsch in 1911 for a new genus and species, Syntonoptera schucherti, from the Upper Carboniferous of Mazon Creek, Illinois. Although the unique specimen on which the species was based consisted of only a wing fragment, the presence of several intercalary, triad veins was of unusual interest. During the 75 years that have passed since then, only six additional specimens of the family have been found (Carpenter, 1938, 1944; Richardson, 1956), all of them in the Mazon Creek beds. The latest of these specimens was sent to me for study by Dr. E. S. Richardson, Jr., a few months before his death, and I have only recently had the opportunity to study it and prepare illustrations. While working on this fossil, I decided to reexamine at the same time the other five specimens in the family known to me. A review of these specimens is included here, followed by revised diagnoses of the family and of the two known genera.

A new genus and species of Platyischnopidae from the sandy intertidal of two localities in the north of Chile are described. Ensigeropus cachinalito n. gen., n. sp. is similar to Eudevenopus Thomas & Barnard, 1983 in most characters; however, it presents characters hitherto not reported in the family, as the lobate upper lip and the absence of a mandibular molar. The new taxon is easily recognized among all American Platyischnopidae by the presence of a conspicuous tooth on the posterior margin of the basis of pereopod 7, a character present also in species of the Australian genus Tomituka Barnard & Drummond, 1979.
