Holothurien-Sklerite aus dem Dachsteinkalk (Ober-Trias) der nördlichen Kalkalpen

By dissolving Dachstein-limestone with acetic acid, Holothurian sclerites were obtained, i. e. sieve plates and wheels. One new species of the genusCalclamna, two new species of the genusCalclamnella, and the well known speciesFissobractites subsymmetrica Kristan-Tollmann were received within the family Calclamidae. For the first time the family Priscopedatidae is represented in the Triassic by two new species of the genusPriscopedatus and byStaurocumites cf.bartensteini Deflandre-Rigaud. Within the family Theeliidae four new species can be adjoined to the genusTheelia whileAcanthotheelia spinosa Frizzell & Exline could be confirmed by comparison.     

A review of species of the genus <Emphasis Type="Italic">Diaphorus</Emphasis> (Diptera,Dolichopodidae) in the Palaearctic Region

The history of studying the genus Diaphorus is described. Seventeen species have been studied. A key to species of the genus Diaphorus of the Palaearctic fauna, including 37 species, and a catalogue of the Palaearctic species with synonyms are given. Diaphorus oldenbergi Parent, 1925 is regarded as a synonym of the species D. nigrotibia Strobl, 1893 (syn. n.). The new species Diaphorus sublautus sp. n. from Azerbaijan is described. Lectotypes of D. dolichocercus Stackelberg, D. parenti Stackelberg, D. ussuriensis Stackelberg, and D. varifrons Becker are designated.     

New subfamily Proschizophoriinae of dalmanellid Brachiopds

Proschizophoria Maillieux is restudied and found to be related to the Silurian genusIdiorthis McLearn and a new genusCordatomyonia, type speciesCordatomyonia shupei, n. sp.Proschizophoria, Idiorthis, andCordatomyonia are united in the new subfamily Proschizophoriinae which is assigned to the dalmanellid family Rhipidomellidae. Rhipidomellidae and its included subfamilies Heterorthinae, Rhipidomellinae, and Proschizophoriinae are emended and newly diagnosed. A new dalmanellid genus,Megasalopina, is proposed for the Lower Devonian species“Dalmanella” elevata Williams & Breger and its allies. It is thought to have been derived from the draboviinid genusSalopina Boucot and therefore belongs to the Schizophoriidae.Dalmanellopsis Khalfin is removed from the synonymy ofLevenea and is shown to be related toSalopina.     

A new method for quantitative determination of members of the genusSaccharomyces in mixtures with other yeast genera

A new method for the quantitative determination of members of the genusSaccharomyces in mixtures with other yeasts is described. It is based on the higher resistance of theSaccharomyces species toward phenylhydrazine. The method is not applicable only toSaccharomyces fragilis and to some of the species grouped sometimes under the genus Zygosaccharomyces. The method described can be used for detecting Saccharomyces individuals in cannery or wine-making raw materials and products, for purity control of production and collection strains of yeasts and for detecting contamination withSaccharomyces species during fodder yeast production.     

A review of the genus <Emphasis Type="Italic">Deporaus</Emphasis> (Coleoptera,Rhynchitidae) from the Russian fauna: 1. Subgenera <Emphasis Type="Italic">Pseudapoderites</Emphasis> and <Emphasis Type="Italic">Japonodeporaus</Emphasis>

The genus Deporaus from the Russian fauna is revised. Four species (D. pacatus, D. azarovae, D. septentrionalis, and D. hartmanni) of the subgenera Pseudapoderites and Japonodeporaus are found. Keys to the subgenera and to the species of the subgenus Pseudapoderites are given. The genus Deporaus, subgenera Pseudapoderites and Japonodeporaus, and four species are redescribed. The distribution of these species in Russia is discussed.     

Genetic diversity among eight <Emphasis Type="Italic">Dendrolimus</Emphasis> species in Eurasia (Lepidoptera: Lasiocampidae) inferred from mitochondrial COI and COII,and nuclear ITS2 markers

Background

Moths of genus Dendrolimus (Lepidoptera: Lasiocampidae) are among the major pests of coniferous forests worldwide. Taxonomy and nomenclature of this genus are not entirely established, and there are many species with a controversial taxonomic position. We present a comparative evolutionary analysis of the most economically important Dendrolimus species in Eurasia.

Results

Our analysis was based on the nucleotide sequences of COI and COII mitochondrial genes and ITS2 spacer of nuclear ribosomal genes. All known sequences were extracted from GenBank. Additional 112 new sequences were identified for 28 specimens of D. sibiricus, D. pini, and D. superans from five regions of Siberia and the Russian Far East to be able to compare the disparate data from all previous studies. In total, 528 sequences were used in phylogenetic analysis. Two clusters of closely related species in Dendrolimus were found. The first cluster includes D. pini, D. sibiricus, and D. superans; and the second, D. spectabilis, D. punctatus, and D. tabulaeformis. Species D. houi and D. kikuchii appear to be the most basal in the genus.

Conclusion

Genetic difference among the second cluster species is very low in contrast to the first cluster species. Phylogenetic position D. tabulaeformis as a subspecies was supported. It was found that D. sibiricus recently separated from D. superans. Integration of D. sibiricus mitochondrial DNA sequences and the spread of this species to the west of Eurasia have been established as the cause of the unjustified allocation of a new species: D. kilmez. Our study further clarifies taxonomic problems in the genus and gives more complete information on the genetic structure of D. pini, D. sibiricus, and D. superans.

     

On the First Finds of the Genus <Emphasis Type="Italic">Djanaliparkinsonia</Emphasis> (Stephanoceratidae,Ammonoidea) in the Upper Bajocian of the Northern Caucasus

The genus Djanaliparkinsonia Kutuzova, 1975 was originally described as an endemic subgenus of the genus Parkinsonia (family Parkinsoniidae of the superfamily Perisphinctoidea) from the Upper Bajocian (middle member of the Degibadam Formation) of the Gissar Range (Uzbekistan). A new species D. alanica sp. nov. is established from the Upper Bajocian Garantiana garantiana Zone (upper member of the Djangura Formation) based on occurrences in the Northern Caucasus (Karachay-Cherkessia). Macroconchs and microconchs of the new species are described from the two localities on the Kuban and Kyafar rivers. Djanaliparkinsonia sp. is identified from the lower subzone of the Parkinsonia parkinsoni Zone of the Kyafar River. The species composition and geographic range of Djanaliparkinsonia are expanded: a species previously described from Germany as Garantiana bentzi Wetzel, 1954 also assigned to the genus. The genus Djanaliparkinsonia is assigned to the subfamily Garantianinae of the family Stephanoceratidae (superfamily Stephanoceratoidea).     

On Late Jurassic–Early Cretaceous oysters of the genus <Emphasis Type="Italic">Deltoideum</Emphasis> Rollier (Bivalvia,Ostreoidea) from Siberia

Morphology, palaeoecology, and phylogeny of oysters of the genus Deltoideum Rollier from the Upper Jurassic and Lower Cretaceous deposits of Siberia are discussed. The diagnosis and composition of the genus are revised. A new endemic subgenus, Boreiodeltoideum subgen. nov., of the genus Deltoideum is described. This subgenus includes two species, D. (B.) praeanabarensis (Zakharov) and D. (B.) anabarensis (Bodylevsky).     

A Review of the Ant Genus <Emphasis Type="Italic">Dolichoderus</Emphasis> Lund, 1831 (Hymenoptera,Formicidae: Dolichoderinae) of Mexico

Mexican ants of the genus Dolichoderus are revised. Five species of the genus are recorded: D. bispinosus (Olivier, 1792), D. diversus Emery, 1894, D. lutosus (Smith, 1858), D. mariae Forel, 1885 and D. plagiatus (Mayr, 1870). Dolichoderus tridentanodus Ortega-De Santiago et Vásquez-Bolaños, 2012 is synonymized with Camponotus mucronatus Emery, 1890. Early records of D. germaini Emery, 1894 and D. lugens Emery, 1894 from Mexico are misidentifications and those species are excluded from the list of the Mexican fauna. Dolichoderus mariae Forel, 1885 is newly reported for the fauna of Mexico. Identification key to Mexican Dolichoderus species is given.     

New and little known crickets of the subfamily phalangopsinae (Orthoptera,Gryllidae): 5. Neotropical taxa of the tribe Paragryllini

One new genus, two new subgenera, and eight new species from Ecuador, Brazil, and Venezuela are described.

A review of fur-mites of the genus <Emphasis Type="Italic">Dubininetta</Emphasis> Fain &amp; Lukoschus, 1978 (Acariformes: Listrophoridae), ectoparasites of moles (Soricomorpha: Talpidae)

The fur mite genus Dubininetta Fain & Lukoschus, 1978 (Acariformes: Listrophoridae) represented by ectoparasites of moles (Soricomorpha: Talpidae) is revised. An amended diagnosis of this genus is provided. Two new species are described from moles in Vietnam: Dubininetta euroscaptor n. sp. from Euroscaptor parvidens (Miller) and Dubininetta abramovi n. sp. from Euroscaptor subanura Kawada, Son & Can. The insufficiently described D. taiwanensis (Fain & Lukoschus, 1978) from Mogera insularis (Swinhoe) (type-host) is redescribed based on the type-specimens and numerous newly collected in the Russian Far East specimens from Mogera robusta Nehring. The host ranges are considered for all species of Dubininetta. A key to the five species presently known in this genus is provided.     

Gall midges of the supertribe Stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic Region,with descriptions of new taxa from the Late Eocene Rovno amber: 1. <Emphasis Type="Italic">Stomatosema,Vanchidiplosis, Clarumreddera</Emphasis> gen. n.

Three recent genera are included in the supertribe Stomatosematidi: Stomatosema (16 species), Vanchidiplosis (4 species), and Didactylomyia (3 species). Seven species of the genus Stomatosema and two species of the genus Vanchidiplosis occur in the Palaearctic Region. No reliable findings of representatives of the supertribe were known in fossilized condition. One new genus and 3 new species are described from amber of the Late Eocene age (Rovno Region): Stomatosema iljieteugeniae sp. n., Clarumreddera korneyevi gen. n. et sp. n., and C. conceptiva sp. n.     

Genetic polymorphism,haplotype distribution,and phylogeny of <Emphasis Type="Italic">Daphnia</Emphasis> (Cladocera: Anomopoda) species from the water bodies of russia as inferred from the 16S mtDNA gene sequencing

The data on the genetic polymorphism of the most widespread Daphnia species occupying different water bodies of Russia are presented. The phylogenetic relationships between the examined species were established, and the haplotype networks were constructed. A fragment of the 16S mitochondrial DNA gene was used as a genetic marker. The results of molecular phylogenetic analysis generally coincided with modern concepts in the systematics of the genus Daphnia. The representatives of the divergent mitochondrial lineages within the D. longispina, D. pulex, and D. magna complex remain poorly investigated morphologically. For D. dentifera, a new habitat on the territory of Russia, namely, the water bodies of the Lake Baikal basin, was identified. A conclusion was made that the 16S mtDNA gene could be successfully used in phylogeographic analysis of the genus Daphnia.     

A review of the genus <Emphasis Type="Italic">Deporaus</Emphasis> (Coleoptera,Rhynchitidae) from the Russian fauna: 2. Subgenera <Emphasis Type="Italic">Roelofsideporaus</Emphasis> and <Emphasis Type="Italic">Deporaus</Emphasis>

The subgenera Roelofsideporaus and Deporaus s. str. of the genus Deporaus with four species (D. affectatus, D. unicolor, D. nidificus, and D. betulae) recorded from the Russian fauna are revised. Keys to the species of the subgenus Roelofsideporaus and to the females of the subgenera Roelofsideporaus and Deporaus s. str. are given. The distribution of D. nidificus in Russia is not confirmed.     

Kluyveromyces wikenii andKluyveromyces cicerisporus spp.n.

Two new species of the genusKluyveromyces, K. wikenii andK. cicerisporus are described.     

A new species of <Emphasis Type="Italic">Panopsis</Emphasis> (Proteaceae) from Bahia,Brazil

Recent collections from Bahia, Brazil included a new species of Panopsis from the Atlantic rainforest. So far it is only known with fruits, which are much larger than in most species of the genus. Panopsis magnifructa is described and compared to other species in the genus. It is only the second species of the genus known in the State of Bahia, Brazil.     

A new species ofProteus isolated from larvae of the gypsy mothPorthetria dispar (L.)

Characteristics of a slime-producing bacterium isolated from living and dead gypsy moth larvae were determined. The bacterium was found to be a motile, gram-negative rod, which fermented glucose, but not lactose. It was oxidase-negative, hydrolyzed urea, deaminated phenylalanine and produced H₂S. These characteristics are common to several members of the genusProteus. In addition to the unique feature of slime production, a biochemical comparison with other members of the genus showed that it differed markedly from described species ofProteus; thus the new speciesProteus myxofaciens was proposed.
