New sepulcids (Hymenoptera: Sepulcidae) from the Lower Cretaceous of Asia: II. Ghilarellinae and Trematothoracinae

Five new species of sepulcids (Hymenoptera: Sepulcidae) are described from the Lower Cretaceous of Transbaikalia and Mongolia (localities Khasurty, Baissa, and Bon-Tsagan). The new species belong to the subfamilies Ghilarellinae and Trematothoracinae: Ghilarella alexialis sp. nov., G. masculina sp. nov., Trematothorax zhangi sp. nov., T. brachyurus sp. nov., and T. extravenosus sp. nov. The genus Trematothoracoides Zhang et al., 2001 (syn. nov.) is synonymized with Trematothorax Rasnitsyn, 1988. A complete list of species of Sepulcidae is provided.     

New stoneflies (Insecta: Perlida = Plecoptera) from the late Mesozoic locality Khasurty,Transbaikalia

From the Lower Cretaceous locality Khasurty, western Transbaikalia, a new genus and species, Rasnitsyrina culonga, gen. et sp. nov. are described in the family Perlariopseidae. R. desiliens (Sinitshenkova, 1987), originally described in the genus Karanemoura Sinitshenkova, 1987, is transferred to the new genus. Two new species belonging to recent families are described: Dimoula khasurtensis sp. nov. (Nemouridae) and Jurataenionema rohdendorfi sp. nov. (Taeniopterygidae). All new species are described from fossils of adults.

A new coleopteran genus, Parelateriformius, gen. nov., comprising the species P. communis, sp. nov., P. villosus, sp. nov., P. capitifossus, sp. nov., and P. mirabdominis, sp. nov., is described from Daohugou deposits, Inner Mongolia, China, and is assigned to the infraorder Elateriformia. The systematic position of the new genus within the suborder Polyphaga is discussed.     

Ichneumonids of the subfamily Tanychorinae (Insecta: Hymenoptera: Ichneumonidae) from the Lower Cretaceous of Transbaikalia and Mongolia

A new species, Tanychora loki, sp. nov., and a new genus and species, Megachora sibirica gen. et sp. nov., are described from the Lower Cretaceous of Transbaikalia and Mongolia. The genus Tanychora Townes, 1973 is divided into two genera: Tanychora s. str., composed of T. petiolata Townes, 1973 (type species), T. sinensis Zhang, 1991, and T. loki sp. nov., and Amplicella, gen. nov., composed of A. sessilis (Townes, 1973) (type species), A. exquisite (Zhang et Rasnitsyn, 2003), A. beipiaoensis (Zhang et Rasnitsyn, 2003), and A. spinata (Zhang et Rasnitsyn, 2003). The frequency of occurrence of ichneumonids in the principal Cretaceous localities of central and northern Asia is calculated.

One poorly preserved specimen, Praeichneumon sp., is described. Rudiments of the second anal vein A2 and internal vein a₁–a₂ and bullae in crossveins of the fore- and hindwing are described in Praeichneumonidae for the first time.     

A Middle Miocene endemic freshwater mollusc assemblage from an intramontane Alpine lake (Aflenz Basin,Eastern Alps,Austria)

The mollusc fauna of the early Middle Miocene (Langhian) intramontane Alpine Lake Groisenbach is described for the first time. The shells derive from the Feistring Formation in the Aflenz Basin in Austria, which was covered by Lake Groisenbach. The assemblage is moderately diverse with 12 gastropod and 2 bivalve species, suggesting shallow lacustrine and fluvial settings. Among the gastropods, only Theodoxus crenulatus (Klein, 1853) is known from other Miocene localities, whilst all other species are documented so far only from Lake Groisenbach. None of the Early and Middle Miocene lake systems of the Alpine-Carpathian Foredeep and the Balkan Peninsula displays any faunistic resemblance with this new fauna. Even coeval lake faunas from the close-by Graz Basin have no species in common with Lake Groisenbach. This pattern points to a surprising endemicity and biogeographic fragmentation in the Central European freshwater systems during the Early and Middle Miocene. The uniqueness of the newly described fauna is also indicated by the completely erratic occurrence of the otherwise African-Mediterranean genus Bulinus, which is unknown from all other central European Miocene freshwater systems. Emmericia roetzeli Harzhauser and Neubauer nov. sp., Nematurella zuschini Neubauer and Harzhauser nov. sp., Romania fastigata Neubauer and Harzhauser nov. sp., Odontohydrobia groisenbachensis Neubauer and Harzhauser nov. sp., Odontohydrobia pompatica Neubauer and Harzhauser nov. sp., Odontohydrobia styriaca Harzhauser and Neubauer nov. sp., Planorbis austroalpinus Harzhauser and Neubauer nov. sp., Gyraulus sachsenhoferi Harzhauser and Neubauer nov. sp., Bulinus corici Harzhauser and Neubauer nov. sp., Ferrissia crenellata Harzhauser and Neubauer nov. sp. and Stagnicola reinholdkunzi Harzhauser and Neubauer nov. sp. are introduced as new species.     

Taxonomic review of Hemistola Warren, 1893 from China,with descriptions of seven new species (Lepidoptera: Geometridae,Geometrinae)

The genus Hemistola Warren from China is reviewed, and seven new species are described: H. viridimargo, sp. nov., H. glauca sp. nov., H. asymmetra sp. nov., H. arcilinea sp. nov., H. flavifimbria sp. nov., H. orbiculosoides sp. nov. and H. stueningi sp. nov. Two species, acyra and christinaria, are transferred from Hemistola to Maxates and Comostola, respectively: Maxates acyra comb. nov. and Comostola christinaria comb. nov. Including the 25 species previously known from China, a total of 32 species is now recorded. All Chinese species are redescribed. Generic characters based on all species are summarized. Illustrations of adults and genitalia are presented.     

New click beetles (Coleoptera: Elateridae) from the cretaceous of Russia and Kazakhstan

A new tribe, two new genera, and seven new species of click beetles are described: Pollostelaterini, trib. nov., Pollostelater baissensis, gen. et sp. nov. from the Lower Cretaceous of Transbaikalia (Baisa locality), five new species in the genus Cryptocoelus Dolin et Nel C. sinitshenkovae, sp. nov. (Romanovka locality), C. shcherbakovi, sp. nov., C. baissensis, sp. nov., C. lukashevichae, sp. nov., C. dolini, sp. nov. (all from Baisa locality), and Turonelater giganteus, gen. et sp. nov. from the Turonian of Southern Kazakhstan (Kzyl-Dzhar locality).     

New species of sap beetles (Coleoptera: Nitidulidae: Nitidulini) from the Baltic and Bitterfeld ambers

A new genus, Microsoronia, gen. nov., and new species of this genus, M. hoffeinsorum, sp. nov. from the Bitterfeld amber and M. kerneggeri sp. nov., M. nigerrima sp. nov., and M. interfax, sp. nov. from the Baltic amber, are described. The earliest known member of the genus Phenolia, P. (Lasiodites) angustitibialis, sp. nov., is described from the Baltic amber. The systematic position of these two genera, their possible evolution, as well as the possible ecology and bionomics of their members are discussed. It is shown that “Phenolia” incapax Scudder, 1890 should be included in the family Peltidae, rather than Nitidulidae.     

New mayflies (Insecta: Ephemerida = Ephemeroptera) from the Upper Mesozoic locality of Khasurty,Western Transbaikalia

A new genus and four new species are described from the Upper Mesozoic locality of Khasurty, Western Transbaikalia: Mesobaetis crispa sp. nov. and Proameletus branchiatus sp. nov. from the family Siphlonuridae s. l., Furvoneta khasurtensis sp. nov. from Mesonetidae, and Baikalogenites firmus gen. et sp. nov. from the family Hexagenitidae. One poorly preserved specimen is identified as Mesogenesia from the family Mickoleitiidae. The unique mayfly generic assemblage of this locality, its possible age, and ecology are discussed.     

New species of sap beetles (Coleoptera: Nitidulidae: Epuraeinae,Cybocephalinae) from the Baltic amber

A new genus, Baltoraea gen. nov., two new species of this genus, B. insignis sp. nov. and B. simillima sp. nov., and three other new species, Cybocephalus (Cybocephalus) balticus sp. nov., C. (C.) electricus sp. nov. and C. (C.) kerneggeri sp. nov. are described from the Late Eocene Baltic amber. The systematic position of the genus Baltoraea and presumable bionomics of the new sap beetles are discussed.

A new genus, Rovnocapnia gen. nov., with new species R. atra sp. nov. and R. ambita sp. nov., from the family Capniidae, and a new genus and species Palaeoleuctra acuta gen. sp. nov., from the family Leuctridae, of the suborder Nemourina (Euholognatha), are described from Late Eocene Rovno amber. Familial assignment of one additional specimen (suborder Perlina, infraorder Perlomorpha (Systelognatha)), represented by a nymphal skin, is obscure due to its incomplete preservation.     

Ammonites of Tethyan origin in the Ryazanian stage of the Russian platform: Genus <Emphasis Type="Italic">Riasanella</Emphasis> gen. nov.

A new ammonite genus Riasanella is described from the Ryazanian Stage of the Russian Platform (type species R. rausingi sp. nov.). The new species R. plana sp. nov., R. olorizi sp. nov., and R. riasanitoides sp. nov. are described. These species come from the lower, strongly condensed beds of the Riasanites rjasanensis Zone of the Moscow Region. The upper subzone of this zone in the Ryazan Region contains specimens of Riasanella, identified in open nomenclature. The new genus is assigned to the family Himalayitidae; one of its species is a possible ancestor of Riasanites Spath.
