Apophyses,verticiles, and denticles in skeletons of Late Paleozoic radiolarians of the subfamily Entactiniinae

Morphostructural analysis of secondary skeletal elements, such as apophyses on the main spines and verticiles on the secondary spines of certain Late Paleozoic radiolarians of the subfamily Entactiniinae allow their taxonomic rank to be raised to genus. The presence of denticles on the secondary spines is only evidence of particular species. Three skeleton morphotypes are established: primary morphotype A, verticillate morphotype B, and apophyseal morphotype C. A new species, Entactinia mariannae sp. nov., and two new genera, Apophysiacus gen. nov. with five species, A. ichikawai (Caridroit et De Wever, 1984), A. minuta (Feng, 2007), A. praepycnoclada (Nazarov et Ormiston, 1983), A. pycnoclada (Nazarov et Ormiston, 1985), and A. sakmaraensis (Kozur et Mostler, 1989), and Verticillides gen. nov. with three species, V. nazarovi nom. nov., V. nestellae sp. nov., and V. verticillatus sp. nov., are described.

Lamellicorn Beetles (Coleoptera,Scarabaeoidea) of Manchuria (China): Fauna,Ecology, and Zoogeography

The species composition and taxonomic structure of lamellicorn beetles of Northeast China are considered. A total of 317 species from 86 genera, 42 tribes, 18 subfamilies, and 6 families are known to occur in the fauna of Manchuria. Seven species are recorded from China for the first time: Trox scaber (Linnaeus, 1767), Glyptotrox ineptus (Balthasar, 1931), Aegialia (Psammoporus) kamtschatica Motschulsky, 1860, Aphodius (Acrossus) superatratus Nomura et Nakane, 1951, Aphodius (Chilothorax) grafi Reitter, 1901, Maladera spissigrada (Brenske, 1897), and Valgus hemipterus hemipterus (Linnaeus, 1758); in addition, 18 species are recorded as new to the fauna of Manchuria. Among 177, 219, 208 and 226 species recorded from the Manchurian part of Inner Mongolia, Heilongjiang, Jilin, and Liaoning, 20, 29, 14 and 19 species are new to the region, respectively. The ecological and zoogeographical features of Scarabaeoidea in Manchuria are analyzed. Data on the trophic structure, phenology, and distribution of all the taxa are presented.     

Review of the fauna of the bug families Ceratocombidae,Tingidae, Microphysidae,and Reduviidae (Heteroptera) of the Middle and South Urals,with analysis of the zoogeographie structure of the Tingidae fauna

Based on the material of the authors’ collections from the South Ural Reserve (Republic of Bashkortostan), Sverdlovsk and Chelyabinsk provinces, the collections of the Zoological Institute of the Russian Academy of Sciences, the Ilmen State Reserve (Chelyabinsk Province), and the Institute of Plant and Animal Ecology of the Ural Branch of the Russian Academy of Sciences (Yekaterinburg), and also the reliable literature data, an annotated list of the true bug fauna of the Middle and South Urals is compiled for the first time. The list includes representatives of the families Ceratocombidae (1 species), Tingidae (45 species of 14 genera), Microphysidae (1 species), and Reduviidae (2 species of 1 genus). The known fauna of the Middle Urals (Perm Territory and Sverdlovsk Province) includes 24 species of Tingidae and 1 species of Microphysidae; that of the South Urals includes 1 species of Ceratocombidae, 41 species of Tingidae, 1 species of Microphysidae, and 2 species of Reduviidae. Six species are recorded from the Urals for the first time: Ceratocombus (Xylonannus) brevipennis Poppius, 1910 (Ceratocombidae), Acalypta gracilis gracilis (Fieber, 1844), Agramma tropidopterum Flor, I860 (Tingidae), Loricula (Myrmedobia) exilis (Fallén, 1807) (Microphysidae), Empicoris culiciformis (De Geer, 1773), and E. vagabundus (Linnaeus, 1758) (Reduviidae). The families Ceratocombidae and Microphysidae were not previously known from this region. The following numbers of species are recorded for the first time for different regions of the Middle and South Urals: for Perm Territory, 2 species of Tingidae; for Sverdlovsk Province, 11 species of Tingidae and 1 of Microphysidae; for Bashkortostan, 1 species of Ceratocombidae, 13 of Tingidae, 1 ofMicrophysidae, and 2 species of Reduviidae; for Chelyabinsk Province, 3 species of Tingidae. The Tingidae fauna of the Middle and South Urals mostly includes species widespread in the latitudinal and longitudinal directions, including 4 Holarctic (8.9%) and 12 Trans-Palaearctic species (26.7%). Ranges of 24 species (53.3%) mainly lie in the “humid” northern part of the Palaearctic (the humid complex of species). Ranges of 21 species (46.7%) mainly lie in the southern part of the Palaearctic, i.e., the Tethyan Region (the arid complex), the Tingidae fauna of the Middle Urals including only 2 species (8.3%) of that complex. Seven species (17.1%) of Tingidae form the arid element in the fauna of Orenburg Province: Kalama henschi (Puton, 1892), Galeatus vitreus Golub, 1974, G. scrophicus Saunders, 1876, Tingis (Tingis) pusilla (Jakovlev, 1873), T. (Tropidocheila) renovata Golub, 1977, T. (Tr.) maculata (Herrich-Schaeffer, 1838), Dictyla subdola (Horvath, 1905). Ranges of 7 species (15.5% of the whole studied fauna of Tingidae) are limited to the Middle and South Urals in the east and northeast. Ranges of 8 other species (17.8%) extend eastwards, beyond the Urals no farther than the south of Western Siberia and Western Kazakhstan. The mountain territory of the Middle and the South Urals obviously serves as a significant orographic and climatic barrier on the way of eastward expansion of some Western- and Central-Palaearctic species of Tingidae.     

Nemestrinid flies (Diptera,Nemestrinidae) in the fauna of Eastern Europe and the Caucasus

The ranges of eight species [Fallenia fasciata (Fabricius, 1805), Neorhynchocephalus tauscheri (Fischer, 1812), Nemestrinus caucasicus (Fischer, 1806), N. bombiformis Portschinsky, 1892, N. brandti (Bequaert, 1938), N. laetus obscuripennis (Portschinsky, 1887), N. reticulatus Latreille, 1802, and Trichopsidea costata (Loew, 1875)] from Eastern Europe and the Caucasus are discussed. With the exception of Nemestrinus caucasicus, the other species are rare in the territory studied; their latest findings are referred to the late nineteenth and early twentieth centuries. These species should be considered as endangered species and included into the Red Data Books of the corresponding regions. N. obscuripennis (Portschinsky, 1887) is regarded as a Caucasian-Anatolian subspecies of N. laetus (Loew, 1873) basing on the study of lecto-and paratypes of the former. A key for identification of the genera and species considered is given.     

Life cycles of 17 riffle-dwelling mayfly species (Baetidae,Heptageniidae, and Ephemerellidae) in central Japan

We described the life cycles of 17 riffle-dwelling mayfly species in a central Japanese stream. Both species of Baetidae (Alainites yoshinensis Gose and Baetis thermicus Uéno) and two of nine species of Heptageniidae (Ecdyonurus scalaris Kluge and Epeorus latifolium Uéno/l-nigrus Matsumura) in this stream were multivoltine (more than one generation per year). Seven other heptageniid species (two unidentified species of Cinygmula, Epeorus aesculus Imanishi, E. curvatulus Matsumura, E. ikanonis Takahashi, E. napaeus Imanishi, and Rhithrogena japonica Uéno) and all six species of Ephemerellidae [Cincticostella elongatula (McLachlan), C. nigra (Uéno), Drunella basalis (Imanishi), D. ishiyamana Matsumura, D. sachalinensis (Matsumura), and D. trispina (Uéno)] were essentially univoltine.     

A synopsis of gall midges associated with conifers,with description of a new species of the genus <Emphasis Type="Italic">Kaltenbachiola</Emphasis> Hedicke (Diptera,Cecidomyiidae: Lasiopterinae) from Yakutia,damaging cones of the Siberian spruce (<Emphasis Type="Italic">Picea obovata</Emphasis>)

The world fauna comprises 134 species from 52 genera of gall midges associated with plants of the order Pinales (3 families, 16 genera and 74 species); 14 genera are specific to Pinales. The distribution of genera and species of gall midges over host plant taxa is described. The Holarctic genus Kaltenbachiola comprises four species all developing in the spruce (Picea spp.) cones. Earlier, K. strobi (Winnertz), widely distributed in Europe, was the only species known in the Palaearctic. A new species Kaltenbachiola anastasiae sp. n. is described, which damages cones of Picea obovata in Central Yakutia. The phylogenetic relationships of Kaltenbachiola with close genera specific to Pinales are characterized, and an updated diagnosis of the genus with additional morphometric parameters and keys to the pine-specific genera of the tribe Dasineurini and to species of the genus Kaltenbachiola are given. The host associations and specific traits of biology and distribution of Kaltenbachiola species are considered.

Diversity,molecular phylogeny and fingerprint profiles of airborne <Emphasis Type="Italic">Aspergillus</Emphasis> species using random amplified polymorphic DNA

In the present study, diversity and phylogenetic relationship of Aspergillus species isolated from Tehran air was studied using random amplified polymorphic DNA (RAPD)–polymerase chain reaction (RAPD-PCR). Thirty-eight Aspergillus isolates belonging to 12 species i.e. A. niger (28.94 %, 11 isolates), A. flavus (18.42 %, 7 isolates), A. tubingensis (13.15 %, 5 isolates), A. japonicus (10.52 %, 4 isolates), A. ochraceus (10.52 %, 4 isolates), and 2.63 %, 1 isolate from each A. nidulans, A. amstelodami, A. oryzae, A. terreus, A. versicolor, A. flavipes and A. fumigatus were obtained by settle plate method which they were distributed in 18 out of 22 sampling sites examined. Fungal DNA was extracted from cultured mycelia of all Aspergillus isolates on Sabouraud Dextrose Agar and used for amplification of gene fragments in RAPD-PCR using 11 primers. RAPD-PCR data was analyzed using UPGMA software. Resulting dendrogram of combined selected primers including PM1, OPW-04, OPW-05, P160, P54, P10 and OPA14 indicated the distribution of 12 Aspergillus species in 8 major clusters. The similarity coefficient of all 38 Aspergillus isolates ranged from 0.02 to 0.40 indicating a wide degree of similarities and differences within and between species. Taken together, our results showed that various Aspergillus species including some important human pathogenic ones exist in the outdoor air of Tehran by different extents in distribution and diversity and suggested inter- and intra-species genetic diversity among Aspergillus species by RAPD-PCR as a rapid, sensitive and reproducible method.

Some of the revealed species are critically endangered in several countries of western Europe. The studied protected areas play an important role in conservation of species diversity and in the distribution of several rare species.     

Foraminifera and their associations of a possibly Rhaetian section of the Nayband Formation in central Iran,northeast of Esfahan

The following paper describes the foraminiferal fauna and associated faunal assemblages of the bedded and reef carbonates of the Upper Triassic (most probably Rhaetian) Nayband Formation, which are exposed in a section south of the small town of Bagher-Abad, northeast of Esfahan. Foraminifers are extremely rare in sponge- or coral-dominated bioconstructions and in the bedded carbonates of the Nayband Formation in central Iran. Some carbonate beds are composed of bioclastic wackstone/packstone. These are exposed in the solenoporacean horizon at the uppermost part of the section. Here, the aulotortid- and trocholinid-type foraminifers are relatively abundant. The following foraminiferal taxa with different abundances were found within the carbonates of the investigated section: Trocholina umbo Frentzen, T. turris Frentzen, T. gracilis Blau, Aulotortus tumidus (Kristan-Tollmann), Aulotortus tenuis (Kristan), Aulotortus friedli (Kristan-Tollmann), Coronipora etrusca (Pirini), Semiinvoluta clari Kristan, Turrispirillina? licia variabilis Blau, Galeanella? laticarinata Al-Shaibani, Carter and Zaninetti, Ophthalmidium sp., Agathammina sp., “Sigmoilina” schaeferae Zaninetti, Planiinvoluta carinata Leischner, Planiinvoluta sp., Nubecularia sp., Endothyra sp., Paeolituonella sp. and some sessile agglutinated and nodosariid types. All mentioned taxa are very rare, except the involutinid and trocholinid types. The following species are described as new: Trocholina blaui nov. sp., Spirilina? iranica nov. sp., and Coronipora serraforma nov. sp. Trocholina blaui is usually attached to solenoporacean thalli. Four foraminiferal associations, which are named after the occurrence of the abundant species, were distinguished as Aulotortus tumidus association, Aulotortus friedli association, Trocholina umbo association, and Trocholina blaui association. Aulotortid types and Trocholina umbo were found within the bioclastic wackstone/packstone carbonates. Trocholina blaui is abundant in solenoporacean framestones. The foraminiferal association of investigated carbonates contains a mixed fauna, known from Upper Triassic–Liassic in the Tethyan realm. Carbonates of the whole investigated section are dated—due to occurrence of the genus Aulotortus, with species A. tumidus (Kristan-Tollmann), A. tenuis (Kristan), and A. friedli (Kristan-Tollmann)—as Upper Triassic (most probably Rhaetian). The “typical” foraminifers occurring in the reef biotopes in the northwestern Tethys are either missing or extremely rare in the Iranian bioconstructions.     

New and little known species of the dance-fly subgenus <Emphasis Type="Italic">Xanthempis</Emphasis> Bezzi,genus <Emphasis Type="Italic">Empis</Emphasis> L. (Diptera,Empididae), from the Caucasus

Five new species of the subgenus Xanthempis Bezzi are described from the Caucasus: Empis (Xanthempis) annae sp. n. (Russia: Krasnodar Territory), E. (X.) grichanovi sp. n. (Russia: Krasnodar Territory; Georgia), E. (X.) pseudoconcolor sp. n. (Russia: Krasnodar and Stavropol territories; Georgia: Abkhazia), E. (X.) teberdaensis sp. n. (Russia: Karachay-Cherkessia), and E. (X.) zamotajlovi sp. n. (Russia: Krasnodar Territory and Adygea). The females of E. (X.) alanica Shamshev and E. (X.) kovalevi Shamshev are described for the first time. New data on the distribution of some previously described species are reported. The geographical distribution of Xanthempis is discussed. A key to Xanthempis species from the Caucasus is compiled.     

Studies of the true bugs of Xinjiang,Northwestern China. III. Water bugs and semiaquatic bugs (Heteroptera: Nepomorpha,Gerromorpha)

In Xinjiang (Western China), the fauna of water bugs and semiaquatic bugs comprises 28 species of 7 families belonging to the infraorders Nepomorpha Popov, 1968 and Gerromorpha Popov, 1971. The present paper provides new data on the distribution of 19 species of 6 families (Nepidae, Corixidae, Naucoridae, Notonectidae, Hebridae, and Gerridae). Four species of the family Corixidae, Micronecta griseola Horváth, 1899, Hesperocorixa linnaei (Fieber, 1848), Paracorixa kiritshenkoi (Lundblad, 1933), and Sigara seistanensis (Distant, 1920), and one species of the family Hebridae, Hebrus pilipes Kanyukova, 1997, are recorded for the first time for China. The family Hebridae and three species of the family Corixidae, Cymatia rogenhoferi (Fieber, 1864), Corixa dentipes Thomson, 1869, and Paracorixa caspica (Horváth, 1878), are new to the fauna of Xinjiang. The record of Gerris odontogaster (Zetterstedt, 1828) whose distribution in Northwestern China had been considered doubtful was confirmed. A key to the species of the genus Micronecta from Middle Asia and Western China is given. Differences between the two closely related species Sigara seistanensis (Distant, 1920) and S. striata (Linnaeus, 1758) are discussed, and their distinctive features are listed.     

Isolation,characterization and virulence of bacteria from <Emphasis Type="Italic">Ostrinia nubilalis</Emphasis> (Lepidoptera: Pyralidae)

Isolation, characterization and virulence of the culturable bacteria from entire tissues of larval Ostrinia nubilalis (Hübner) (Lepidoptera: Pyralidae) were studied to obtain new microbes for biological control. A total of 16 bacteria were isolated from living and dead larvae collected from different maize fields in the Eastern Black Sea Region of Turkey. The bacterial microbiota of O. nubilalis were identified as Pseudomonas aeruginosa (On1), Brevundimonas aurantiaca (On2), Chryseobacterium formosense (On3), Acinetobacter sp. (On4), Microbacterium thalassium (On5), Bacillus megaterium (On6), Serratia sp. (On7), Ochrobactrum sp. (On8), Variovorax paradoxus (On9), Corynebacterium glutamicum (On10), Paenibacillus sp. (On11), Alcaligenes faecalis (On12), Microbacterium testaceum (On13), Leucobacter sp. (On14), Leucobacter sp. (On15) and Serratia marcescens (On16) based on their morphological and biochemical characteristics. A partial sequence of the 16S rRNA gene was also determined to confirm strain identification. The highest insecticidal activities were obtained from P. aeruginosa On1 (80%), Serratia sp. On7 (60%), V. paradoxus On9 (50%) and S. marcescens On16 (50%) against larvae 14 days after treatment (p < 0.05). Also, the highest activity from previously isolated Bacillus species was observed from Bacillus thuringiensis subsp. tenebrionis Xd3 with 80% mortality within the same period (p < 0.05). Our results indicate that P. aeruginosa On1, Serratia sp. On7, V. paradoxus On9, S. marcescens On16 and B. thuringiensis subsp. tenebrionis Xd3 show potential for biocontrol of O. nubilalis.
