Les brachiopodes carbonifères des Pyrénées centrales françaises: 2: Étude des Orthida et des Spiriferida; biostratigraphie,paléoécologie,paléobiogéographie

This paper follows the first part: Legrand-Blain &alii, 1983,Geobios, n^o 16, fasc. 3.The brachiopods here described from the «Culm are: Schizophoria cf. resupinata, Rhipidomella michelini, Actinoconchus aff. paradoxus, Lamellosathyris gr. lamellosa, Cleiothyridina (Leiothycridina) nov. sp. gr. okensis, Podtsheremia (s.l.) convenarum nov. sp., Neospirifer gr. derjawini, Anthracospirifer (?) sp., Brachythyrina (Anthracothyrina) perextensa nov. subgen., nov. sp., «Spirifer lujkiensis, Zaissania nov. sp., Kitakamithyris or Torynifer (?) sp., Martinia minima. From shales associated with the Ardengost limestones, slightly different faunas are: Podtsheremia (s.l.) convenarum (?), Anthracospirifer (?) sp., Brachythyrina (Anthracothyrina) bressoni nov. subgen., nov. sp., Phricodothyris mosquensis, Martinia buckmani.The brachiopods from Ardengost limestones andassociated shales, well dated, are of upper Serpukhovian age. The «Culm ones might be heterochroneous, with Serpukhovian and (?) Bashkirian elements. The paleoecology of the brachiopods from limestones and associated shales indicates moderate and low energy environments. The «Culm brachiopods display both resedimentation and delicate preservation features. There is evidence of rather close palaeobiogeographic relationships with the northern Sahara: during the late Serpukhovian, a «Sahara-Pyrénées region could be distinguished, at the western part of the vast Tethysian province.     

Brachiopods of the suborder Delthyridina Ivanova (order Spiriferida) from the Lower and Middle Devonian of northeastern Russia

New brachiopods of the suborder Delthyridina Ivanova (order Spiriferida) from the Lower and Middle Devonian of northeastern Russia, Ivanothyris costatus sp. nov. (subfamily Delthyridinae), Eoreticularia lata sp. nov., Yania gen. nov. with the type species Y. tumida sp. nov. (subfamily Eoreticulariinae), Reticulariopsis equitans Modzalevskaya, and R. (?) borealis sp. nov. (subfamily Reticulariopsinae) are described.     

Phylogenetic analysis of the Cenozoic family Sieblosiidae (Insecta: Odonata), with description of new taxa from Russia, Italy and France

We describe the following Sieblosiidae: an unamed “gen. and sp. A” from the Miocene of Italy, Miostenolestes zherikhini nov. gen., nov. sp., Paraoligolestes stavropolensis nov. sp., Stenolestes fasciata nov. sp. (all from the Miocene of North Caucasus), Stenolestes (?) adygeianensis nov. sp. (Oligocene of North Caucasus), and Stenolestes cerestensis nov. sp. (Oligocene of France). The genus Sieblosia Handlirsch, 1906 is restored. A new phylogenetic analysis of the Sieblosiidae is proposed. The two taxa “gen. and sp. A” and Oligolestes fall in most inclusive positions in the same clade with the Sieblosiidae. Within the Sieblosiidae sensu stricto, the two clades (Paraoligolestes + (Parastenolestes + Stenolestes)) and (Parastenolestes + Stenolestes) are the best supported. The family Sieblosiidae seems to be restricted to the Oligocene-Miocene of Europe.     

New Devonian and Carboniferous bryozoans of the Holy Cross Mountains (central Poland)

New bryozoans from the Middle-Upper Devonian (Eifelian-Frasnian) and the Lower Carboniferous (Tournaisian) of the Holy Cross Mountains in central Poland are described: Bigeyella sparsa gen. et sp. nov., B. separata gen. et sp. nov., Eridopora singula sp. nov., Leptotrypa pulchra sp. nov., Kysylschinipora klarae sp. nov., Coelotubulipora rara sp. nov., Alternifenestella genuina sp. nov., Exfenestella polonica sp. nov., and Rectifenestella localis sp. nov. Some paleogeographic and stratigraphic aspects of the Paleozoic deposits of this region are discussed and main bryozoan localities are described.

Rich radiolarian associations are investigated. They include nine new species from the Upper Cretaceous (Coniacian-Santonian) metal-bearing beds of the Perapedhia Formation of southern Cyprus: Dorypyle concinna sp. nov., Gongylothorax mangaleniensis sp. nov., Heliocryptocapsa macroporus sp. nov., H. perapediensis sp. nov., Mita guttiformis sp. nov., Pseudoeucyrtis belogorskensis sp. nov., P. cypricus sp. nov., Rhopalosyringium mangaleniense sp. nov., and Sandovalella trihedra sp. nov.     

Ten new species of caddisflies (Insecta: Trichoptera) from the Baltic amber

Ten new species of caddisflies of the families Polycentropodidae (nine) and Molannidae (one) are described from the Eocene Baltic amber: Holocentropus peregrinator sp. nov., H. proximorepertus sp. nov., H. dugoi sp. nov., H. fundamentalis sp. nov., H. telergon sp. nov., Plectrocnemia varigoria sp. nov., P. synthesia sp. nov., P. novokshonovi sp. nov., Nyctiophylax valideturbidus sp. nov., and Molanna okraina sp. nov.     

Late Norian (Triassic) Radiolaria from the Kotel’nyi Island (New Siberian Islands,Arctic, Russia)

Two radiolarian assemblages were recovered from upper Norian strata of the Kotel’nyi Island (Russia); the first assemblage, from the Monotis zabaikalica Subzone (lower part of Upper Norian), is represented by Betraccium inornatum Blome, Dumitricaella (?) parva Sugiyama, Ferresium titulense Blome and 24 other species; the second assemblage, from the Monotis subcircularis Subzone (upper part of Upper Norian), is represented by Crucella sp. cf. C. angulosa Carter, Kahlerosphaera acris Bragin, K. sp. cf. K. parvispinosa Kozur & Mostler, Pseudohagiastrum crassum (Carter) and 11 other species. Both assemblages have common taxa with Upper Norian and Rhaetian radiolarian assemblages of British Columbia and they display clear Boreal features: low taxonomic diversity, abundance of taxa known from high-latitude regions, absence or rare presence of taxa known from low-latitude areas. The presence of early representatives of nassellarian genera Droltus and Parahsuum is very distinctive. Six new species are described: Pseudohagiastrum spinosum nov. sp., Cantalum boreale nov. sp., Plafkerium carteri nov. sp., Droltus guttaeformis nov. sp., Laxtorum blomei nov. sp., L. glacialis nov. sp.

Miocene ostracods from the Tremiti Islands and Hyblean Plateau: biostratigraphy and description of new and poorly known species

The main taxonomic and stratigraphical results of a study of ostracods from the middle-late Miocene of the Tremiti Islands and the Hyblean Plateau are presented. The faunas are mostly typical of deep thermospheric or psychrospheric bathyal environments. Excluding a few, mostly juvenile shallow water contaminants, a total of 127 species were recorded. Twenty-four taxa are discussed herein; of these, 13 species (Cytherella dissimilis nov. sp., Cytherella parvula nov. sp., Cytherella subtilis nov. sp., Argilloecia triangularis nov. sp., Retibythere (Retibythere)? claudii nov. sp., Retibythere (Retibythere)? gibba nov. sp., Cytheropteron (Cytheropteron) joachinoi nov. sp., Cytheropteron (Aversovalva) consuetum nov. sp., Cytheropteron (Aversovalva) trimerumense nov. sp., Cytheropteron (Aversovalva) turgidum nov. sp., Loxoconcha julianii nov. sp., Buntonia whatleyi nov. sp., Pterygocythere nuda nov. sp.) and a subspecies (Costa tricostata dorsoarcuata nov. subsp.) are described as new, while six are left in open nomenclature. The stratigraphical distribution of ostracods is expressed in terms of planktonic foraminiferal zones. Information obtained from this study enriches biostratigraphical data on Mediterranean Miocene deep-sea ostracods, especially with respect to the Langhian.     

New ancyloceratidae (Ammonoidea) from the Aptian of the Ulyanovsk region,Middle Volga

A new genus Pseudoancyloceras gen. nov. with the type species P. calinovense sp. nov. and five new species of Ancyloceratidae (Australiceras (Proaustraliceras) elegans sp. nov., Audouliceras vyrystaykense sp. nov., A. brusyankense sp. nov., A. mordovense sp. nov., Tropaeum (Tropaeum) elaurkense sp. nov.) are described from the Aptian of the Ulyanovsk region, Middle Volga.     

New nematocerans (Insecta: Diptera) from the Late Jurassic of Mongolia

New nematoceran taxa are described based on isolated wings from the Late Jurassic Shar Teg locality (Mongolia): ?Nannotanyderus incertus sp. nov. (Tanyderidae), Crenoptychoptera liturata sp. nov. (Ptychopteridae), Chaoburmus amphilogos sp. nov., Mesocorethra cincta sp. nov. (Chaoboridae), Rasnicynomma additum gen. et sp. nov., and Palaeoperissomma ornatum sp. nov. (Perissommatidae).     

New Emsian foraminifers from of the Karpinsky Horizon limestones Severouralsk Bauxite Mine

Four new foraminiferal species, Parathuramminites mutilatus sp. nov., P. stelliformis sp. nov., P. subrus sp. nov., and P. minutus sp. nov., and a new genus and species, Algaeformis porosus gen. et sp. nov. from clayey limestones and marls of the basal Karpinsky Horizon (Emsian Stage, Lower Devonian) of the Severouralsk Bauxite Mine are described.     

Discovery of the Misellina Zone (latest Kungurian) in the Lentas unit of the Pindos Series (Crete)

The origin and significance of the Lentas unit in southern Crete (Greece) is still subject to controversies. New stratigraphical and palaeontological results allow correlations with the classical Pindos-type series in Greece. In particular, new datings from reworked fossiliferous limestone pebbles within the Lentas unit are presented. These data concern especially the carbonate microfacies and carbonate microfossils from the latest Early Permian (i.e., from the late Kungurian Substage or Misellina Zone). For the first time in Greece, this period is recognized as being rich in foraminifers and calcareous algae. These fossils are described; especially, two dasycladales Likanella (?) cretae nov. sp. and Uragiellopsis bonneauii nov. sp. are established. The presence of these reworked Palaeotethyan sediments at the base of the Lentas unit suggests a derivation from the Palaeotethyan active margin (arc/fore-arc series).     

New grylloblattids of the family Lemmatophoridae (Insecta: Grylloblattida) from the Permian of Russia

New grylloblattids of the family Lemmatophoridae (Insecta: Grylloblattida), Artinska sojanensis sp. nov., Sylvaprisca colorata sp. nov., and Uraloprisca lisca gen. et sp. nov., from the Soyana locality (Lower Kazanian, Arkhangelsk Region) and Paraprisca solikamskensis sp. nov. from the Tyul’kino locality (Ufimian, Perm Region) are described. Two species are transferred from the genus Paraprisca to Uraloprisca gen. nov.: Uraloprisca uralica (G. Zalessky, 1952), comb. nov. and Uraloprisca causaria (Novokshonov, 2000), comb. nov. (both from the Kungurian of the Perm Region). The evolution of the family is discussed.
