New Genus And Species

A new genus and species, Glanomerope virgoferroa gen. et sp. nov., the first Permian record of a scorpionfly from Germany, is described from the Niedermoschel black shale, Meisenheim Formation, Lower Rotliegend of the Saar-Nahe basin. It is assigned to the Protomeropidae, the oldest known family of the holometabolous superorder Panorpida, ranging from the Bashkirian-Moscovian (Late Carboniferous) to the Roadian. It confirms that this family was very diverse in Central Europe during the Early Permian. Protomeropidae possibly became extinct in the course of major climatic changes that progressively affected the supercontinent Pangea after the Artinskian, although generally these changes seem to have more severely affected some other insects such as the palaeopteran Dictyoneuridae than holometabolous groups.

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.

A new paoliid genus and species, Permomertovia simpliciradius, and a new grylloblattid species, Oborella monsjovisensis, are described from the Early Permian (Lower Rotliegend) of Sitters and Niedermoschel in the Saar-Nahe Basin, Germany. These discoveries increase the insect diversity documented from the Niedermoschel black shale and furthermore confirm the high diversity of Paoliidae in Central Europe during this period.

The Early Permian (late Sakmarian to early Artinskian) adrianitid ammonoid Nevadoceras steelei new genus and species occurs in a fauna containing the ammonoids Properrinites Elias, Prothalassoceras Böse, Daraelites Gemmellaro, Almites Toumanskaya, Bamyaniceras Termier and Termier, Akmilleria Ruzhencev, Agathiceras Gemmellaro, Metalegoceras Schindewolf, Stenolobulites Mikesh, Glenister, and Furnish, Crimites Toumanskaya, Neocrimites Ruzhencev and the conodonts Sweetognathus whitei (Rhodes) and Mesogondolella bisselli (Clark and Behnken). This fauna occurs in a concretionary interval within micritic basinal facies of the Dry Mountain trough at Portuguese Springs, White Pine County, east-central Nevada.

New Family

The Paleozoic to Mesozoic grade ‘Protozygoptera’ is revised. It appears to be composed of two main lineages, namely the superfamily Permagrionoidea, and the Archizygoptera. The latter taxon forms a monophyletic group together with Panodonata (=crown-Odonata plus their closest stem-relatives). Therefore, the ‘Protozygoptera’ as previously understood is paraphyletic. Diagnostic characters of the ‘Protozygoptera’, Permagrionoidea, and Archizygoptera are re-evaluated. The Permolestidae is considered as a junior synonym of the Permagrionidae. The following new taxa are described: Permolestes sheimogorai new species, Permolestes soyanaiensis new species, Epilestes angustapterix new species, Solikamptilon pectinatus new species (all in Permagrionidae); Lodeviidae new family (for Lodevia); Luiseiidae new family (including Luiseia breviata new genus and species); Kennedya azari new species, Kennedya pritykinae new species, Kennedya ivensis new species, Progoneura grimaldii new species (all in Kennedyidae); Engellestes chekardensis new genus and species (in Bakteniidae); and Azaroneura permiana new genus and species (in Voltzialestidae). The Kaltanoneuridae and Oboraneuridae are revised. The evolution of protozygopteran Odonatoptera during the transition from the Permian to the Triassic is discussed. The larger taxa of the permagrionoid lineage apparently did not cross through the Permian–Triassic boundary, unlike the more gracile Archizygoptera. This last group shows a remarkable longevity from the late Carboniferous to the Early Cretaceous. It also presents a great taxonomic and morphological stability, with genera ranging from the Permian to the Triassic, and a wing venation pattern nearly unchanged from the late Carboniferous to the Late Triassic. The mass extinction at the end of the Permian period seemingly had a minor effect on these tiny and delicate insects.

Early permian strata in two displaced terranes of the McCloud belt contain a small biconic gastropod of distinctive appearance, Vesperispira humboldtiana new genus and species. This trochiform gastropod has a strongly oblique aperture with interrupted peristome, a small sinus on the peripheral margin of the shell, and lamellose shell. This gastropod is an easily recognized biogeographic indicator of the McCloud province biota, because of its lamellose ornamentation. Occurrence of this gastropod in strata of the Pine Forest Range of northwestern Nevada provides additional evidence for including rock units of the Black Rock terrane within the McCloud Belt, a grouping of several displaced terranes along the western margin of North America (Stevens et al., 1990) that contain fossil biotas rich in endemic species.

Study of a nearly complete skeleton of a small amniote, preserved as part and counterpart in Upper Carboniferous limestone slabs of the Hamilton Quarry, Kansas, indicates that it is a new genus and species of varanopid synapsid. Archaeovenator hamiltonensis gen., and sp. nov. is the oldest known varanopid. Phylogenetic analysis indicates that it is the sister taxon to all other known varanopids. Discovery of this new varanopid is important because it improves our knowledge of the terrestrial fauna of the Hamilton quarry, expands the known diversity of Late Carboniferous basal synapsids, and extends the fossil record of Varanopidae deeper within the Stephanian. Varanopidae has the longest fossil record (Late Carboniferous – upper Middle Permian) of all known clades of basal synapsids.

Phylogenetic Implications

AbstractGallotupus oudardi, new genus and species of Meganeuridae is described from the Late Carboniferous of Northern France. Potential phylogenetic implications of two wing venation structures present in meganeurids are discussed on the basis of this new fossil. The most basal antenodal brace Ax0 could be a potential synapomorphy of the Meganeuridae with the Odonatoclada. The 'subnodus' could have been a structure related to larval tracheation in meganeurids, exapted as a part of the complex nodal structure in modern Odonata, related to flight. Lastly the shortly petiolated wing of Gallotupus is analogous to similar wing shapes of several Mesozoic, Cenozoic, and modern nodialatan lineages.
