Le genre leptaenopyxis (brachiopoda,leptaenidae) dans le Devonien du Massif Armoricain (France)

The study of genus LeptaenopyxisHavlicek, 1963 in the Lower Devonian from Armorican Massif allows to recognize four species: Leptaenopyxis kerfornei n. sp., Leptaenopyxis cf. bouei (Barrande), Leptaenopyxis sp. 1 and Leptaenopyxis sp. 2. These species were described, until now, under specific name boueiBarrande, 1848. From this study it follows some biostratigraphical and palaeobiogeographical results for the Armorican Massif and its relations with surrounding areas during Lower Devonian time.     

Proposal to replace the illegitimate genus name Prescottia Jones et al. 2013 with the genus name Prescottella gen. nov. and to replace the illegitimate combination Prescottia equi Jones et al. 2013 with Prescottella equi comb. nov

Recently we proposed that Rhodococcus equi (Magnusson 1923) Goodfellow and Alderson 1977 be transferred to a novel genus, Prescottia, as Prescottia equi comb. nov. However, in accordance with Principle 2 and Rule 51b(4) of the Bacteriological Code (1990 Revision), the bacterial genus name Prescottia Jones et al. 2013 is deemed illegitimate as this name has been used previously for a plant genus within the family Orchidaceae. Consequently, a new genus name, Prescottella gen. nov. is proposed for the bacterial taxon and a new combination Prescottella equi comb. nov. is proposed for the type species.     

Phylogeny of the genus <Emphasis Type="Italic">Lophozia</Emphasis> (Dumort.) Dumort. s. str. inferred from nuclear and chloroplast sequences ITS1-2 and TRNL-F

Maximum parsimony and maximum likelihood phylogenetic trees were constructed for 21 taxa of Lophozia s. str. and the related genera, Schistochilopsis (5 species), Protolophozia elongata, and Obtusifolium obtusum based on combined nuclear ITS1-2 and chloroplast trnL-F DNA sequences. The trees were characterized by similar topology. It was demonstrated that the genus Lophozia s. str. was monophyletic, excluding L. sudetica, which deserved isolation into a distinct cryptic genus. The species distribution among the clades disagreed with the sections distinguished based on anatomical and morphological data. The relationships within the genus Schistochilopsis were consistent with the sectioning of the genus, based on morphological characters. Analysis of molecular data provided more precise definition of the systematic position of a number of taxa. A low level of genetic divergence of geographically distant forms was demonstrated.     

Sur la morphologie externe et interne de Rotorboides granulosa (Heron-Allen & Earland) emendation du genre Rotorboides Sellier de Civrieux, 1977 (Foraminiferida)

Discorbis valvulata granulosa HERON-ALLEN and EARLAND, which has been found by the present authorsin the recent deposits of Watamu beach (Kenya), is the type-species of the genus RotorboidesSELLIER de CIVRIEUX, 1977. The study of this species has permitted to describe in detail its outer and inner morphology, to discuss its previous assignments (Discorbis, Rotorbinella) and to emend the genus Rotorboides.     

Gall midges of the supertribe stomatosematidi (Diptera,Cecidomyiidae) in the Palaearctic region,with descriptions of new taxa from the late Eocene Rovno Amber. 2. The genera <Emphasis Type="Italic">Didactylomyia</Emphasis> and <Emphasis Type="Italic">Rovnodidactylomyia</Emphasis> gen. n.

One new genus (Rovnodidactylomyia Fedotova et Perkovsky, gen. n.) and four new species (Didactylomyia dlusskyi sp. n., Rovnodidactylomyia zosimovichi gen. n. et sp. n., R. sidorenkoi sp. n., and R. iconica sp. n.) are described from an amber sample of the late Eocene Period (Rovno District, Ukraine). Two species from a Baltic amber sample of the late Eocene Period, described earlier in the genus Bryocrypta, are attributed to the genus Rovnodidactylomyia (R. girafa (Meunier, 1904) comb. n. and R. capitosa (Meunier, 1904)). The first fossil species of the genus Didactylomyia is described for the first time; two contemporary Palaearctic species are recorded. Keys to the species of the genus Didactylomyia are given.     

Neogene phasianids (Aves: Phasianidae) of Central Asia: 1. Genus <Emphasis Type="Italic">Tologuica</Emphasis> gen. nov.

A new genus, Tologuica, with two species (T. aurorae sp. nov. and T. karhui sp. nov.), from the Middle Miocene of the Sharga locality (western Mongolia) is described. The new genus shares some characters with the extinct genera Palaeocryptonyx, Palaeortyx, and Plioperdix and with extant Coturnix. The foot structure suggests that Tologuica resembled in ecology the European genus Palaeortyx and was probably adapted to an arboreal mode of life, in contrast to the terrestrial Coturnix and Plioperdix.     

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. The former genus Hattersleya Nischk et Otte is considered as a subgenus of the genus Neoacla Des. Acla multivenosa Chop., A. reticulata Chop., A. vicina Chop., Selvacla choreutes Otte, S. salvator Otte, S. alsiosus Otte, and S. sophos Otte are transferred to the genus Neoacla, and Desutteria epiplatys Nischk et Otte, to the genus Silvastella Des.-Gr. New data on the geographical and ecological distribution of some species are given.     

Cytogenetic study of the Endemic Malagasy lemur: Hapalemur,I. Geoffroy, 1851

The genus Hapalemur Gray, 1870 is comprised of two species: H. simus Gray, 1870 and H. griseus Link, 1795. Hapalemur griseus contains, according to Osman Hill (1953), two species: H. g. griseus (Link, 1795) and H. g. olivaceus (I. Geoffroy, 1851). Recent ecological investigation by Petter & Peyrieras (1970) has helped the discovery of a third subspecies of H. griseus in the region of Lake Alaotra. Whilst making the cytogenetic study of the genus Hapalemur, we have completed the chromosomal evolution's schema, originated by Chu & Swomley (1961).     

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.     

<Emphasis Type="Italic">Subsessila turbinata</Emphasis> gen. et. sp. nov. (Beltraniaceae), a <Emphasis Type="Italic">Beltrania</Emphasis>-like fungus from Thailand

A new monotypic Beltrania-like genus, Subsessila, with its type species S. turbinata, is described, illustrated and compared with similar genera. The new genus is introduced in the family Beltraniaceae based on phylogenetic analysis and morphological characters. Subsessila can be easily distinguished from other Beltrania-like genera by dark setae arising from radially lobed basal cells, mostly lacking macronematous conidiophores. Conidiogenous cells are ampulliform or doliiform and produce turbinate to clavate conidia with rostrate proximal end and rounded distal end. Evidence for establishment of the new genus is provided based on morphological comparison and DNA sequence data analyses.     

Truyolsodontos estauni n. gen., n. sp., Truyolsodontidae,a new family of lamniform sharks from the Cenomanian of northern Spain

Truyolsodontos estauni n. gen., n. sp. is described based on fossil teeth from the middle and upper Cenomanian of northern Spain. The species Protoscyliorhinus magnusLandemaine, 1991 is withdrawn from the genus Protoscyliorhinus and placed in this new one. For the new genus, the new family Truyolsodontidae is proposed.     

<Emphasis Type="Italic">Calcarisporium xylariicola</Emphasis> sp. nov. and introduction of <Emphasis Type="Italic">Calcarisporiaceae</Emphasis> fam. nov. in Hypocreales

During a survey of fungicolous fungi, a novel taxon from the surface of stroma of an unidentified Xylaria species was collected. Phylogenetic analyses showed that this taxon clustered with Calcarisporium sp. and C. arbuscula isolates, but was resolved as a distinct species. A detailed morphological examination coupled with phylogenetic analysis indicated that the taxon represented a new species. Calcarisporium xylariicola sp. nov. is thus introduced. The new taxon is characterized by short conidiophores with swollen bases and less length/width ratio of conidia that distinguish it from other Calcarisporium species. Calcarisporium is presently placed in Hypocreales genera, incertae sedis genus. Species in the genus are largely fungicolous, or occasionally caulicolous or foliicolous, and have hyaline, erect, verticillate conidiophores and sympodial, polyblastic conidiation. A phylogenetic analysis of combined SSU, ITS, LSU, TEF and RPB2 sequence data from Calcarisporium species and other taxa in Hypocreales indicate that Calcarisporium is a distinct lineage from other families. Therefore, a new family, Calcarisporiaceae, in Hypocreales is introduced.     

<Emphasis Type="Italic">Nonomuraea rhizosphaerae</Emphasis> sp. nov., an actinomycete isolated from the rhizosphere soil of a rubber tree (<Emphasis Type="Italic">Hevea brasiliensis</Emphasis> Muell. Arg)

A novel actinomycete, designated strain NEAU-mq18^T, was isolated from the rhizosphere soil of a rubber tree (Hevea brasiliensis Muell. Arg) collected from Xianglu Mountain in Heilongjiang Province, northeast China, and subjected to a polyphasic taxonomic study. The 16S rRNA gene sequence analysis showed that the isolate belongs to the genus Nonomuraea with high sequence similarity to Nonomuraea guangzhouensis NEAU-ZJ3^T (98.5%). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain clusters phylogenetically with N. guangzhouensis NEAU-ZJ3^T and Nonomuraea glycinis NEAU-BB2C19^T. Moreover, key chemotaxonomic properties including the major menaquinones, fatty acid composition and phospholipid profile also confirmed the affiliation of the strain to the genus Nonomuraea. However, some physiological, morphological and biochemical properties, and low DNA–DNA relatedness values, enabled the strain to be differentiated from closely related species of the genus Nonomuraea. Thus, strain NEAU-mq18^T is concluded to represent a novel species of the genus Nonomuraea, for which the name Nonomuraea rhizosphaerae sp. nov. is proposed. The type strain is NEAU-mq18^T (=CGMCC 4.7431^T=DSM 105761^T).     

Phylogenetic relationships in the genus <Emphasis Type="Italic">Primula</Emphasis> L. (Primulaceae) inferred from the ITS region sequences of nuclear rDNA

The nucleotide sequences of the nuclear rDNA ITS regions were determined for 34 species of the genus Primula L. and one species of the genus Cortusa L., family Primulaceae Vent., and used to infer the phylogenetic relationships among these species. In this analysis species of the Russian flora and the flora of adjacent territories were studied for the first time. The results clarified the taxomic structure of the genus Primula and confirmed the entity of some of its sections; but not the subgenera sensu J.Richards. Our data do not support an independent status of the genus Cortusa, placing it as one of the terminal lineages of the section Cortusoides Balf. f. in the genus Primula.     

<Emphasis Type="Italic">Leifiporia rhizomorpha</Emphasis> gen. et sp. nov. and <Emphasis Type="Italic">L. eucalypti</Emphasis> comb. nov. in Polyporaceae (Basidiomycota)

A new poroid wood-inhabiting fungal genus, Leifiporia, is proposed, based on morphological and molecular evidence, which is typified by L. rhizomorpha sp. nov. The genus is characterized by an annual growth habit, resupinate basidiocarps with white to cream pore surface, a dimitic hyphal system with generative hyphae bearing clamp connections and branching mostly at right angles, skeletal hyphae present in the subiculum only and distinctly thinner than generative hyphae, IKI–, CB–, and ellipsoid, hyaline, thin-walled, smooth, IKI–, CB– basidiospores. Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analysis based on molecular data of ITS + nLSU sequences showed that Leifiporia belonged to the core polyporoid clade and was closely related to Diplomitoporus overholtsii and Lopharia cinerascens, and then grouped with Pycnoporus and Trametes. Further investigation was obtained for more representative taxa in the Polyporaceae based on nLSU sequences, in which the results demonstrated that the genus Leifiporia formed a monophyletic lineage with a strong support (100 % BS, 100 % BP, 1.00 BPP). Both morphological and molecular evidence confirmed the placement of the new genus in the core polyporoid clade. In addition, a new combination, Leifiporia eucalypti, is proposed based on examination of its type material and phylogeny.     

A review of the buprestid genus <Emphasis Type="Italic">Cochinchinula</Emphasis> Volk. With description of new taxa from Thailand,and notes on the composition and classification of the tribe Acmaeoderini (Coleoptera,Buprestidae, Polycestinae)

A review of the Oriental genus Cochinchinula Volk. (Coleoptera, Buprestidae, Polycestinae, Acmaeoderini) comprising three species is presented. The new species C. thailandica and C. bilyi spp. n. and the new genus Thaichinula gen. n. (type species T. ohmomoi sp. n.) from Thailand are described. A key to species of the genera Cochinchinula and Thaichinula is provided. The Nearctic genus Paracmaeoderoides Bellamy and Westcott is transferred from the subtribe Nothomorphina to the subtribe Acmaeoderoidina, and the South African genus Richtersveldia Bellamy is transferred from the subtribe Nothomorphina of Acmaeoderini to the tribe Ptosimini. The generic status is restored for another South African genus, Brachmaeodera Volkovitsh and Bellamy. The main evolutionary trends are discussed, and the taxonomic composition and classification of the tribe Acmaeoderini are clarified.     

<Emphasis Type="Italic">Ponticoccus alexandrii</Emphasis> sp. nov., a novel bacterium isolated from the marine toxigenic dinoflagellate <Emphasis Type="Italic">Alexandrium minutum</Emphasis>

During an investigation of the biodiversity of the cultivable bacterial community associated with paralytic shellfish poisoning toxin-producing marine dinoflagellate, Alexandrium minutum a novel algal-associated bacterium, designated strain AT2-A^T was isolated. 16S rRNA gene sequence similarity analysis showed that the strain is a member of the genus Ponticoccus, with high sequence similarity to Ponticoccus litoralis DSM 18986^T (97.9%) and Ponticoccus lacteus JCM 30379^T (96.0%). However, based on the data obtained for the physiological and biochemical characteristics, and low level of DNA–DNA relatedness analysis, the strain could be genotypically and phenotypically differentiated from two type strains of the genus Ponticoccus. Therefore, this algal-associated bacterial strain is concluded to represent a novel species of the genus Ponticoccus, for which the name Ponticoccus alexandrii sp. nov. is proposed. The type strain is AT2-A^T (CCTCC AB 2017228 ^T = KCTC 52626 ^T ).
