    A new genus and species of basal actinopterygian fish from the Upper Devonian Gogo Formation of Western Australia

    ACTA ZOOLOGICA, Issue 2009
    Brian Choo
    Abstract A new basal actinopterygian, Gogosardina coatesi gen. et sp. nov., is described from the Upper Devonian Gogo Formation of the Canning Basin, Western Australia. The new taxon is known from four prepared specimens that display the typical exceptional preservation of fossil vertebrates from the region. Gogosardina gen. nov. possesses a series of four small postrostrals, no surangular and a highly gracile body covered with over 140 vertical rows of very small scales, all ornamented with separate horizontal ganoine ridges. One specimen contains conodont elements lodged among the branchial arches, indicating dietary habits and a possible cause of death. [source]

    A new tooth-plated lungfish from the Middle Devonian of Yunnan, China, and its phylogenetic relationships

    ACTA ZOOLOGICA, Issue 2009
    Tuo Qiao
    Abstract A new genus and species of tooth-plated lungfish, Sinodipterus beibei gen. et sp. nov., is described from the Qujing Formation (Middle Devonian, late Eifelian) of Zhaotong, Yunnan, China. The new form resembles Dipterus in the skull table, but differs in its tooth-plate: cosmine-like tissue absent near the midline, tooth rows fewer in number (7 to 8) and less divergent radiating, and no reparative dentine layers. Phylogenetic analysis of Devonian lungfish based on a dataset of 150 characters and 33 taxa indicates that the new taxon is more crownward than Dipterus and the clade comprising Adololopas, Sorbitorhynchus and Pillararhynchus. Our results agree broadly with previous cladistic solutions. Diabolepis is placed as a sister group to all other Devonian lungfish. The species referred to Chirodipterus fail to form a monophyletic group. The result shows a large number of convergences corresponding to early radiation of lungfish compressed in time. [source]

    The earliest evidence of host,parasite interactions in vertebrates

    ACTA ZOOLOGICA, Issue 2009
    evics, ns Luk
    Abstract Traces of parasite action have been discovered in the Middle,Upper Devonian fish from Estonia, Latvia and European Russia. Such traces are known in heterostracan Psammolepis venyukovi, antiarchs Asterolepis radiata and Bothriolepis ciecere, sarcopterygians Holoptychius sp., Ventalepis ketleriensis and Eusthenodon sp. nov. The traces include evidence of parasitic fixation and penetration as well as dwelling traces. Pathologies are developed as (1) round fossulae on the external surface of bones and scales; (2) oval fossulae with a slight elevation in the centre of the pit; (3) hollow swellings (possible galls); (4) openings (perforations) that have been repaired to various degrees; (5) variously shaped buttresses on the visceral surface of sarcopterygian scales; and (6) porous spongy formations on the non-overlapped surface of sarcopterygian scales. The round fossulae in sarcopterygian, placoderm and psammosteid skeletal elements could be produced by parasites that are similar to copepod crustaceans. Gall formation in Asterolepis is most likely to be caused by a larva, possibly of a trematode. The perforations of scales (and dermal bones) might arise from the attacks of ectoparasites (copepods?) or different worms. The spongy formations on the Holoptychius scales could be the result of invasion of a unicellular parasite. [source]

    A New Species of Theridion Walckenaer (Araneae: Theridiidae) from Korea

    Bo-Keun SEO
    ABSTRACT A new species, Theridion longipili sp. nov. (Theridiidae), is described from Korea. It is easily distinguished from other congeners by the structure of conductor, radix, median apophysis, and the female epigynum and internal genitalia. [source]

    Subterranean species of the ant genus Crematogaster in Asia (Hymenoptera: Formicidae)

    Shingo HOSOISHI
    Abstract Three Crematogaster ant species, C. (Orthocrema) javanica Menozzi, C. (O.) myops Forel and C. (O.) masukoi sp. nov., share reduced compound eyes which characterizes them among Asian species of the subgenus Orthocrema. The new species is described based on material from Borneo. It can be distinguished from C. javanica and C. myops by its smooth surface of clypeus and acutely produced subpetiolar process. Reduced compound eyes and yellowish body suggest that these three species are subterranean. [source]

    Genus Thubana Walker in Indonesia, with descriptions of four new species (Lepidoptera: Lecithoceridae) and a world catalog of the genus

    Kyu-Tek PARK
    Abstract The genus Thubana Walker (Lepidoptera: Lecithoceridae: Torodorinae) in Indonesia is reviewed, with three known species from Java and four additional new species: Th. raphidodea sp. nov. from Sulawesi, Indonesia and Malaysia; and Th. erycinae sp. nov., Th. apiculalis sp. nov. and Th. sellarius sp. nov. from Sumatra, Indonesia. The previously known species from Java, Th. costimaculella (Snellen), is redescribed for the wing venation and genitalia of both sexes; however, the syntype of Th. heylaertsi (Snellen) is observed only by its photograph. No specimens of Th. heylaertsi and Th. xylogramma Meyrick were found during this study. Photos of all known species, except Th. xylogramma Meyrick, and a key to species are provided. A catalog for the genus with all 46 known species in the world is given. [source]

    Descriptions and biological notes of Ctenoplectra bees from Southeast Asia and Taiwan (Hymenoptera: Apidae: Ctenoplectrini) with a new species from North Borneo

    I-Hsin SUNG
    Abstract Six Ctenoplectra species are recorded from Southeast Asia and Taiwan. They are C. chalybea Smith, C. cornuta Gribodo, C. davidi Vachal, C. elsei Engel, C. sandakana sp. nov. and C. vagans Cockerell. Females of C. sandakana sp. nov. from North Borneo are similar to the mainland species C. chalybea, but differ mainly in the clypeal keel and the length of the antennal segments. The small blackish species, C. cornuta, is distributed in Myanmar, China and Taiwan and C. davidi is distributed in China, Russia and Taiwan; both species are seen at the flowers of Thladiantha. Ctenoplectra chalybea was collected from the Malay Peninsula, Myanmar, Taiwan and Vietnam. Ctenoplectra apicalis Smith and C. kelloggi Cockerell are allied to C. chalybea; however, C. kelloggi is excluded from this study due to insufficient material. A key to the six known Ctenoplectra species is given. The large metallic species, C. chalybea and C. elsei, visit flowers of Momordica cochinchinensis (Lour.) Spreng. For the first time observations on the nest structures of C. chalybea and C. cornuta are presented. They choose remarkable places, such as artificial structures and buildings, for nest sites. The nest architecture prevents rain and direct sunlight from entering the nest. Bees used pre-existing holes or crevices in wood for nesting shelters and collected soil and appeared to mix it with some other substance to build nests. The cell lining materials and rubbing behaviors against the cell wall suggest that Ctenoplectra bees use floral oil mainly for cell lining materials. [source]

    Notes on two species of the subgenus Lyrothorax Chaudoir (Coleoptera: Carabidae; genus Pterostichus), Pterostichus amagisanus Tanaka and Ishida and Pterostichus fujitai Tanaka and Ishida

    Abstract Two species of the subgenus Lyrothorax Chaudoir (Coleoptera: Carabidae; genus Pterostichus), Pterostichus amagisanus Tanaka and Ishida and Pterostichus fujitai Tanaka and Ishida, were revised based on the male endophallus (inner sac everted from aedeagus). P. amagisanus was newly recorded based on a single male from Kyushu, southwest Japan, far from its known distribution (Honshu; the Fuji-Hakone-Izu volcano area), although additional materials are necessary to confirm this record. Despite a highly disjunct distribution, no conspicuous difference was recognized in either external or genital characters between the materials from Honshu and Kyushu. The nominal species P. fujitai was separated into two species, P. fujitai (Honshu) and Pterostichus eoyoritomus sp. nov. (Shikoku; type locality: Mount Jingayama); these two species have some significant differences in the endophallic structures. Character states in male genitalia suggest a sister relationship between P. eoyoritomus sp. nov. and Pterostichus yoritomus Bates. [source]

    A new stem-borer of the genus Bucculatrix (Lepidoptera: Bucculatricidae) from Japan, with description of the life history

    Shigeki KOBAYASHI
    Abstract A new species of bucculaticid moth, Bucculatrix hamaboella sp. nov. (Host plant: Hibiscus hamabo, Malvaceae) is described from Wakayama Prefecture, Japan. The feeding habit of the new species is unique in that: (i) the young larva is a leaf miner forming a long red linear mine but in the later instars the larva becomes a stem borer; (ii) later instar larvae undergo double molts within a cocoonet (molting cocoon); and (iii) penultimate and final instars appear on the surface of the leaf as non-feeding stages. The external non-feeding larvae of B. hamaboella undergoing double molts within one cocoonet are considered to be an abbreviated form of the external feeding instars of other bucculatricids typically making first and second cocoonets, undergoing a single molt within each cocoonet. On the basis of morphological characters, this species is related to the species of Sections I and II (Host: Asteraceae) of Braun (1963), rather than to the species of Section VIII (Host: Malvaceae).

    Arengomyia, new genus for the Colocasiomyia arenga species group (Diptera: Drosophilidae), with description of a new species

    Masako YAFUSO
    Abstract The arenga species group, hitherto consisting of three species, Colocasiomyia arenga, C. pararenga and C. sagittata, is separated from the genus Colocasiomyia, and established as the new genus Arengomyia Yafuso and Toda, gen. nov. Of the three species, C. pararenga Okada, 1990 is synonymized with C. arenga (Okada, 1987). A new species, Arengomyia xanthopleura Yafuso and Toda, sp. nov., is also described. Supplementary descriptions and revisions of some morphological characters are also provided for the known species. [source]

    Systematic and morphological studies of the genus Chaetopleurophora Schmitz (Diptera: Phoridae) occurring in Japan

    Hiroto NAKAYAMA
    Abstract Japanese species of the genus Chaetopleurophora are reviewed. All belong to the C. erythronota group. The following three species from Japan are described: C. rhomboidea sp. nov., C. pygidialis Schmitz and C. dividua sp. nov. The male and female genitalia are studied and further examples of unique characters of the genus including asymmetric features are added. The male aedeagus of the genus is illustrated for the first time. The aedeagus of the species treated in this study consists of only two components, the inner core plate and the outer jacket plate. The jacket plate wraps sinistrally around the core plate. The combination of the core plate and the jacket plate forms complex, asymmetric features of the aedeagus in the Phoridae. The structure around the genital opening in the female genitalia protrudes posteriorly under the segment IX + X, and shows asymmetric features in C. rhomboidea sp. nov. with a bilaterally different degree of sclerotization, shifted genital opening to the right side and a membranous ribbon just on the left side. In addition, C. dividua sp. nov. is different from most of the species in the C. erythronota group, and very closely related to C. multiseriata (known in North America) in the male and female genitalia, wing venation and bristle formation on the scutellum. It is suggested that C. dividua sp. nov. forms a monophyletic group with C. multiseriata and the related species. [source]

    Pollination mutualism between a new species of the genus Colocasiomyia de Meijere (Diptera: Drosophilidae) and Steudnera colocasiifolia (Araceae) in Yunnan, China

    Kohei TAKENAKA
    Abstract A new species of the genus Colocasiomyia de Meijere (Diptera: Drosophilidae) was discovered from inflorescences of Steudnera colocasiifolia K. Koch (Araceae) in Yunnan, China. The new species is described as Colocasiomyia steudnerae Takenaka and Toda, sp. nov., and we investigated the reproductive ecology of both the fly and the plant species. This fly species reproduces in the inflorescences/infructescences of the plant, and depends almost throughout its entire life cycle on the host plant. The fly species is the most abundant flower visitor for S. colocasiifolia and behaves intimately with the flowering events, suggesting that it is the unique and most efficient pollinator for the host plant. Bagging (insect-exclusion) treatment of inflorescences resulted in no fruits. These findings strongly suggest that intimate pollination mutualism has evolved between the fly and the host plant, as are known in other Colocasiomyia flies and Araceae plants. One notable feature of this system is that the new species almost monopolizes the host-plant inflorescence as a visitor, without any cohabiting Colocasiomyia species. In comparison to other cases where two Colocasiomyia species share the same inflorescence and infructescence of Araceae host plants for reproduction by separating their breeding niches microallopatrically between the staminate (upper male-flower) and the pistillate (lower female-flower) regions on the spadix, C. steudnerae exhibits a mixture of stamenicolous and pistillicolous breeding habits.

    Abstract The species of the genus Neochauliodes from Henan are reviewed. Three species are described as new to science: Neochauliodes digitiformis sp. nov., Neochauliodes parasparsus sp. nov. and Neochauliodes sparsus sp. nov. A key to the species from Henan is presented. [source]

    Genus Pagastia Oliver (Diptera: Chironomidae) from Japan, with description of a new species

    Kazuo ENDO
    Abstract A new species, Pagastia hidakamontana sp. nov., is described from the alpine zone of the Hidaka Mountains in Hokkaido, Japan. Pagastia orthogonia Oliver, so far known only from the Nearctic Region, is newly recorded from Japan and redescribed. Females of P. lanceolata (Tokunaga) and P. nivis (Tokunaga) are redescribed, and the synonymy of P. lanceolata with Syndiamesa (Lasiodiamesa) crassipilosa Tokunaga (= Pseudodiamesa crassipilosa) is proposed. Keys to males and females of Japanese species of the genus are provided. [source]

    Discovery of the genus Skidmorella Johnson (Coleoptera: Ptiliidae) in Japan, with descriptions of two new species

    Yoshihiro SAWADA
    Abstract The genus Skidmorella Johnson, previously known only from the South Pacific islands, is discovered in Japan. The type species, Skidmorella magnifica Johnson, is confirmed from Japan as the first record of the species other than the type locality. In addition, two new species, Skidmorella amamiana sp. nov. and Skidmorella quadrisulucia sp. nov., are described from the Ryukyus, Japan. Phylogenetic relationships of the genus Skidmorella and its allies are discussed on the basis of their morphological characters. [source]

    Valeriana andinaBritton and Valeriana mandoniiBritton, described from Bolivia, cannot strictly be separated by reliable distinctive characters. Therefore ValerianaandinaBritton is included into Valeriana mandoniiBritton as follows: V. mandoniiBritton subsp. andina (Britton) Weberlingstat. nov. The descriptions of Valeriana tuberiferaGraebn. and V. bulbosaWedd. were completed and reliable diagnostic characters between both species were accentuated. Valeriana fonckiiPhil.

    The basidiomycete genus Polyporus , an emendation based on phylogeny and putative secondary structure of ribosomal RNA molecules

    FEDDES REPERTORIUM, Issue 7-8 2004
    D. Krüger
    The fungal genus Polyporus is an assemblage of white-rotting lignicolous basidiomycetes. It has undergone considerable expansion and contraction over a period of two and three quarter centuries. Current generic circumscription of Polyporus has kept the genus non-monophyletic. Species of Polyporus infrageneric group Polyporellus are closely related to some species of Lentinus. We introduce data for ITS2 spacer rRNA secondary structure evolution by quasi-independent comparison with large subunit rRNA phylogeny, and suggest a fraction of primary nuclear rDNA ITS sequence data as novel taxonomic character. A major taxonomic shift is suggested, supported by molecular and morphological characters, and allowing inclusion of species with gilled hymenophores in Polyporus. Two new names are proposed: Polyporus phyllostipes D.Krüger, nom. nov. and Polyporus gerdai D.Krüger, nom. nov. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) Die Gattung Polyporus (Basidiomycetes) , eine Emendation auf der Basis von Phylogenie und mutmaßlicher sekundärer Struktur der ribosomalen RNA-Moleküle Die Pilzgattung Polyporus, eine Gruppe Weißfäule erregender holzbewohnender Basidiomyceten, wurde über nahezu drei Jahrhunderte vielfach expandiert und verkleinert. Bei der derzeitigen Gattungsumschreibung von Polyporus gilt die Gattung als nicht-monophyletisch. Arten der Polyporus -Gruppe Polyporellus sind eng verwandt zu einigen Lentinus- Arten. Anhand quasi-unabhängigem Vergleich mit der Phylogenie der rRNA der großen Untereinheit (LSU) stellen wir Daten zur Evolution der ITS2 Spacer rRNA vor, und schlagen ein ITS Kern-rDNA-Fragment als taxonomisches Merkmal vor. Unterstützt mit molekularen und morphologischen Daten wird eine grundlegende taxonomische Verschiebung vorgeschlagen, welche Arten mit Lamellen-Hymenophoren in Polyporus erlaubt. Zwei neue Namen werden vorgeschlagen: Polyporus phyllostipes D.Krüger, nom. nov. und Polyporus gerdai D.Krüger, nom. nov. [source]

    Entre ValerianapotopensisBriq., descripta para Bolivia, y Valeriana humahuacensisBorsini, descripta para Jujuy, la provincia contigua de la Argentina, no se han encontrado características morfológicas para distinguir ambas especies, por eso éstas estarían unidas bajo del nombre ValerianapotopensisBriq. Por otra parte Valeriana bolivianaBritton y Valeriana bangianaGraebn., serían según Graebner (1906) dos especies distintas, pero no dió caracteres seguros para diferen-ciarlas. En este trabajo se observa que la forma de los frutos de los materiales tomados como tipo y paratipos es diferente, frutos ovados, como descripto para V. boliviana, se observan en unos paratipos, también se ven frutos ancho-ovados con un margen grueso, pero los del lectotipo V. boliviana (Rusby 871 NY) tienen un contorno casi circular como una lenteja, con un margen tenue, casi membranoso como los del lectotipo de V. bangiana (Bang 2415 G). Ni los caracteres vegetativos ni los caracteres de los frutos serían suficientes para poder distinguir V. bangianaGraebn. 1906 de V. bolivianaBritton 1891 como especies separadas. Se observa también que Valeriana variabilisGraebn. sería una forma de Valeriana warburgiiGraebn. La primera especie solo se distinguiría por caracteres poco manifiestos como el indumento de los frutos y los pelos frecuentemente se pierden durante de la maduración de los mismos, estos caracteres no serían suficientes para separar las dos especies. Por lo tanto se considera una nueva combinación, Valeriana warburgiiGraebn. subsp. variabilis(Graebn.) Weberling stat. nov. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) ValerianapotopensisBriq., described from Bolivia, and Valeriana humahuacensisBorsini, described from Jujuy, the neighbouring province of Argentina, cannot be distinguished by reliable distinctive characters. This applies especially to the indument of the fruits, since the fruits of Valeriana often become increasingly glabrescent in advanced stages of development, with the mature fruits being completely bald. Therefore both species should be united under the older name ValerianapotopensisBriq. According to Graebner (1906) Valeriana bangianaGraebn., is to be regarded as separate species, differing from Valeriana bolivianaBritton by its vigorous densely foliated stem, a character cer-tainly insufficient for a reliable identification. The fruits of V. boliviana are described as "ovatis", which is confirmed by the para-type material of the Mandon collections. In the paratypes the fruits were found to be lanceolate-ovate (Rusby872) or broadly ovate with prominent nerves and a thickened solid margin (Rusby875). However, the fruits of the holotype Rusby 871 (Fig. 12a, b) present a different shape: compressed fruits of nearly circular outline, with a broad flattened some-what membraneous marginal ring. The same form of fruits, although considerably larger, was found in the type material of Valeriana bangiana. Because of the overlapping of the vegetative characters as well as the forms of the fruits V. bangianaGraebn. 1906 cannot be clearly separated from V. bolivianaBritton 1891, and is included into this species. Valeriana warburgiiGraebn. and V. variabilisGraebn. too cannot be separated at species level because of over-lapping characters. Again the indumentum of the fruits is apparently according to several authors the best key character, but is not at all reliable. However, the outline of the fruits shows some differences. Therefore V. variabilis is included into V. warburgii as follows: V. warburgiiGraebn. subsp. variabilis(Graebn.) Weberling stat. nov. [source]

    A new look at Kedarnatha P.K.Mukh.

    FEDDES REPERTORIUM, Issue 3-4 2004
    & Constance (Umbelliferae)
    A field investigation of Kedarnatha sanctuarii P.K.Mukh. & Constance in its locus classicus and subsequent carpological analysis show the identity of the species and Trachydium garhwalicum H.Wolff, described from the same region of Tehri Garhwal (Uttaranchal, India). As this species differs in some essential characters from Trachydium, Trachyspermum, Chamaesium, Chamaesciadium, Schulzia, the genus Kedarnatha must be retained, and IndoschulziaPimenov & Kljuykov is to be considered as its latter synonym. A new nomenclatural combination, K. garhwalica (H.Wolff) Pimenov & Kljuykov comb. nov. have been proposed to name the type species. Cortia oreomyrrhiformisFarille & Malla and Trachydium hamelianumFarille & Malla are transferred to Kedarnatha [K. oreomyrrhiformis (Farille & Malla) Pimenov & Kljuykov comb. nov. and K. hameliana (Farille & Malla) Pimenov & Kljuykov comb. nov.]. Two new additional species, K. meifoliaPimenov & Kljuykov sp. nova from India and K. vaginataPimenov & Kljuykov sp. nova from Burma, are described. As a result, the genus contains five species, distributed from Himachal Pradesh (India) to Burma. (© 2004 WILEY-VCH Verlag GmbH & Co.

Da diese Art sich in einigen wesentlichen Merkmalen von Trachydium, Trachyspermum, Chamaesium, Chamaesciadium und Schulzia unterscheidet, muss die Gattung Kedarantha beibehalten werden. Die Gattung IndoschulziaPimenov & Kljuykov ist somit ein späteres Synonym. Die neue nomenklatorische Kombination, K. garhwalica(H.Wolff) Pimenov & Kljuykov comb. nov. wird als Typusart vorgeschlagen. Cortia oreomyrrhiformisFarille & Malla und Trachydium hamelianumFarille & Malla werden in die Gattung Kedarnatha überführt [K. oreomyrrhiformis (Farille & Malla) Pimenov & Kljuykov comb. nov. und K. hameliana(Farille & Malla) Pimenov & Kljuykov comb. nov.]. Zwei weitere Arten werden neu beschrieben: K. meifoliaPimenov & Kljuykov sp. nova aus Indien und K. vaginataPimenov & Kljuykov sp. nova aus Burma.

E.Ludwig comb. nov. and Hygrocybe roseascens sp. nova, a tiny related species from the subspecies Cuphophyllus (Agaricales, Hygrophoraceae, Tricholomataceae) The literature on Hygrophorus rigelliaeVelen. is studied and the species is transferred to Hygrocybe. A related tiny wax gill, Hygrocybe roseascens, likewise belonging to subgenus Cuphophyllus is described as a new one. It is characterised by partly squamulose pileus with conspicuously pinkish hues when dry, 1,4-spored basidia and small, (sub)globose spores. The differences between the new species and similar taxa are discussed. A plate with drawings of its habit and microscopic features is given. A coloured plate will be published in Vol. III of my "Pilzkompendium" but is already available at ("Pilzbilder"). [source]

    Revision of the subgenus Wichuraea (M.Roemer) Baker of BomareaMirbel (Alstroemeriaceae)

    FEDDES REPERTORIUM, Issue 3-4 2003
    A. Hofreiter
    The subgenus Wichuraea of Bomarea (Alstroemeriaceae) was last revised by Baker (1888) as part of his revision of the genus Bomarea. Since then the number of validly published names has increased from seven to recently 50, indicating an urgent need for further revision. Extensive field studies in Peru (A. Hofreiter) and depth investigation of herbarium material have led to new insights into the subgenus. As a result a number of Bomarea species formerly placed under Wichuraea are relocated to another subgenus, a large number of names are placed into synonymy and one species, Bomarea vargasiiHofreiter sp. nova, and one subspecies, Bomareaandimarcana subsp. andimarcanaHofreiter comb. nov. und B. andimarcana subsp. densifoliaHofreiter comb. nov., are newly described. A key to the 16 species is given. Field studies revealed that even taxonomically valuable characters can be remarkably variable, even within a single population. This has demonstrably resulted in a high degree of taxa instability in the group. The typical habit and its variability, preferred habitats and the geographical distribution of each species is presented. Revision der Untergattung Wichuraea (M.Roemer) Baker der Gattung BomareaMirbel (Alstroemeriaceae) Die Untergattung Wichuraea wurde zuletzt von Baker (1888) als Teil der Revision von Bomarea (Alstroemeriaceae) revidiert. Seit dieser Zeit hat die Zahl gültig veröffentlichter Namen von sieben auf 50 zugenommen. Eine Revision erscheint deshalb dringend erforderlich. Die Grundlage für diese Arbeit wurde bei ausführlichen Feldstudien in Peru (A. Hofreiter) und umfangreichen Analysen von Herbarmaterial gelegt. Durch die vorliegende Revision wird die Anzahl der Arten auf 16 reduziert. Ein Teil der bisher zu Wichuraea gestellten Arten gehört zu einer anderen Untergattung, ein weiterer Teil der Namen muss in die Synonymie verwiesen werden. Eine Art, Bomarea vargasiiHofreiter sp. nova, und eine Unterart, Bomarea andimarcana subsp. andimarcanaHofreiter comb. nov. und B. andimarcana subsp. densifoliaHofreiter comb. nov., werden neu beschrieben. Feldstudien ergaben eine hohe Variabilität der Merkmale, selbst innerhalb einer Population. Dies hat z. B. allein bei Bomarea dulcis zu 14 Synonymen geführt. Für jede Art werden die typische Wuchsform und deren Variabilität, die bevorzugten Standorte und die geographische Verbreitung dargestellt. [source]

    Burkholderia anthina sp. nov. and Burkholderia pyrrocinia, two additional Burkholderia cepacia complex bacteria, may confound results of new molecular diagnostic tools

    Peter Vandamme
    Abstract Nineteen Burkholderia cepacia -like isolates of human and environmental origin could not be assigned to one of the seven currently established genomovars using recently developed molecular diagnostic tools for B. cepacia complex bacteria. Various genotypic and phenotypic characteristics were examined. The results of this polyphasic study allowed classification of the 19 isolates as an eighth B. cepacia complex genomovar (Burkholderia anthina sp. nov.) and to design tools for its identification in the diagnostic laboratory. In addition, new and published data for Burkholderia pyrrocinia indicated that this soil bacterium is also a member of the B. cepacia complex. This highlights another potential source for diagnostic problems with B. cepacia -like bacteria. [source]

    Mucilaginibacter dorajii sp. nov., isolated from the rhizosphere of Platycodon grandiflorum

    Byung-Chun Kim
    Abstract A Gram-negative, nonmotile and rod-shaped bacterial strain was isolated from the rhizosphere of Platycodon grandiflorum in a study of bacterial diversity, and its taxonomic position was investigated by a genotypic and phenotypic analysis. This isolate, designated as DR-f4, grew at 4,30 °C (optimally at 20,25 °C) and in the presence of 0,1% (w/v) NaCl. It contained MK-7 as the predominant menaquinone. The isolate had activities of catalase, oxidase and ,-galactosidase and hydrolyzed aesculin, casein, carboxymethyl-cellulose, starch and l -tyrosine. The major cellular fatty acids were summed feature 3 (C16:1,7c and/or iso-C15:0 2OH) and iso-C15:0. The DNA G+C content was 42.6 mol%. This isolate belonged to the genus Mucilaginibacter based on phylogenetic analysis using 16S rRNA gene sequences. The nearest phylogenetic neighbors of strain DR-f4T were Mucilaginibacter lappiensis ANJL12T and Mucilaginibacter rigui WPCB133T, with 16S rRNA gene sequence similarity levels of 96.9% and 96.4%, respectively. The genotypic and phenotypic evidence suggests that strain DR-f4T should be classified as a novel species, for which the name Mucilaginibacter dorajii sp. nov. is proposed. The type strain for the novel species is DR-f4T (=KACC 14556T=JCM 16601T). [source]

    Vibrio owensii sp. nov., isolated from cultured crustaceans in Australia

    Ana Cano-Gómez
    Abstract Two bacterial strains (DY05T and 47666-1) were isolated in Queensland, Australia, from diseased cultured crustaceans Panulirus ornatus and Penaeus monodon, respectively. On the basis of 16S rRNA gene sequence identity, the strains were shown to belong to the Harveyi clade of the genus Vibrio. Multilocus sequence analysis using five housekeeping genes (rpoA, pyrH, topA, ftsZ and mreB) showed that the strains form a monophyletic group with 94.4% concatenated sequence identity to the closest species. DNA,DNA hybridization experiments showed that strains DY05T and 47666-1 had 76% DNA similarity to each other, but <70% to their closest neighbours Vibrio harveyi LMG 4044T (,55%), Vibrio campbellii LMG 11216T (,52%) and Vibrio rotiferianus LMG 21460T (,46%). Strains DY05T and 47666-1 could be differentiated from their relatives on the basis of several phenotypic characteristics. The major fatty acids were C15:0 iso 2-OH and/or C16:1,7, C16:0, C18:1,7 and C14:0. Based on the polyphasic evidence presented here, it can be concluded that strains DY05T and 47666-1 belong to the same novel species of the genus Vibrio, for which the name Vibrio owensii sp. nov. is proposed. The type strain is DY05T (=JCM 16517T=ACM 5300T). [source]

    Spathaspora arborariae sp. nov., a d -xylose-fermenting yeast species isolated from rotting wood in Brazil

    FEMS YEAST RESEARCH, Issue 8 2009
    Raquel M. Cadete
    Abstract Four strains of a new yeast species were isolated from rotting wood from two sites in an Atlantic Rain Forest and a Cerrado ecosystem in Brazil. The analysis of the sequences of the D1/D2 domains of the large-subunit rRNA gene showed that this species belongs to the Spathaspora clade. The new species ferments d -xylose efficiently and is related to Candida jeffriesii and Spathaspora passalidarum, both of which also ferment d -xylose. Similar to S. passalidarum, the new species produces unconjugated asci with a single greatly elongated ascospore with curved ends. The type strain of Spathaspora arborariae sp. nov. is UFMG-HM19.1AT (=CBS11463T=NRRL Y-48658T). [source]
