<Emphasis Type="Italic">Kretzschmaria varians</Emphasis> sp. nov., <Emphasis Type="Italic">Xylaria coremiifera</Emphasis> sp. nov. and <Emphasis Type="Italic">Xylaria umbonata</Emphasis> sp. nov. from Costa Rica

Kretzschmaria varians, a species apparently related to K. micropus, is described as new. It is distinguished primarily by having asci with 2 to 8 ascospores with inconstant germination slit length and remains of synnemata on stromata and surrounding substrate. Xylaria coremiifera, described here as new, bears small fragile coremia on pulvinate stromata and the surrounding substrate. Asci often have fewer than 8 ascospores, most frequently 4. Xylaria umbonata, described here as new, produces perithecia around a central umbo that appears to be the remains of a synnema. Ascospores have long spiralling germination slits.     

<Emphasis Type="Italic">Ogataea phyllophila</Emphasis> sp. nov., <Emphasis Type="Italic">Candida chumphonensis</Emphasis> sp. nov. and <Emphasis Type="Italic">Candida mattranensis</Emphasis> sp. nov., three methylotrophic yeast species from phylloplane in Thailand

Five strains (LN12, LN14^T, LN15^T, LN16 and LN17^T) representing three novel methylotrophic yeast species were isolated from the external surface of plant leaves by three-consecutive enrichments. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, the sequence analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene and the phylogenetic analysis, the five strains were assigned to be one novel Ogataea species and two novel Candida species. Three strains (LN12, LN14^T and LN16) represent a single novel species of the genus Ogataea, for which the name Ogataea phyllophila sp. nov. is proposed. The type strain is LN14^T (= BCC 42666^T = NBRC 107780^T = CBS 12095^T). Strain LN15^T was assigned to be Candida chumphonensis sp. nov. (type strain LN15^T = BCC 42667^T = NBRC 107781^T = CBS 12096^T). Strain LN17^T represented another novel species of Candida that was named Candida mattranensis sp. nov. (type strain LN17^T = BCC 42668^T = NBRC 107782^T = CBS 12097^T).     

<Emphasis Type="Italic">Funastrum rupicola</Emphasis> (<Emphasis Type="Italic">Apocynaceae:</Emphasis><Emphasis Type="Italic">Asclepiadoideae</Emphasis>), a new species from Bolivia

Summary   Funastrum rupicola Goyder, a new species of Apocynaceae: Asclepiadoideae from Bolivia, is described and illustrated. The conservation status of this species is assessed.     

<Emphasis Type="Italic">Candida kashinagacola</Emphasis> sp. nov., <Emphasis Type="Italic">C. pseudovanderkliftii</Emphasis> sp. nov. and <Emphasis Type="Italic">C. vanderkliftii</Emphasis> sp. nov., three new yeasts from ambrosia beetle-associated sources

Three new yeast species, Candida kashinagacola (JCM 15019(T) = CBS 10903(T)), C. pseudovanderkliftii (JCM 15025(T) = CBS 10904(T)), and C. vanderkliftii (JCM 15029(T) = CBS 10905(T)) are described on the basis of comparison of nucleotide sequences of large subunit ribosomal DNA D1/D2 region (LSU rDNA D1/D2). The nearest assigned species of the three new species was Candida llanquihuensis. Candida kashinagacola and C. pseudovanderkliftii differed from C. llanquihuensis by 3.8% nucleotide substitution of the region, while C. vanderkliftii did by 4.4%. Three new species differed in a number of physiological and growth characteristics from any previously assigned species and from one another. A phylogenetic tree based on the sequences of LSU rDNA D1/D2 showed that these new species together with Candida sp. ST-246, Candida sp. JW01-7-11-1-4-y2, Candida sp. BG02-7-20-001A-2-1 and C. llanquihuensis form a clade near Ambrosiozyma species. The new species did not assimilate methanol as a sole source of carbon, which supported the monophyly of these non methanol-assimilating species which are closely related to the methylotrophic yeasts. Candida kashinagacola was frequently isolated from the beetle galleries of Platypus quercivorus in three different host trees (Quercus serrata, Q. laurifolia and Castanopsis cuspidata) located in the sourthern part of Kyoto, Japan, thus indicating that this species may be a primary ambrosia fungus of P. quercivorus. On the other hand, C. pseudovanderkliftii and C. vanderkliftii were isolated only from beetle galleries in Q. laurifolia. Candida vanderkliftii was isolated from beetle gallery of Platypus lewisi as well as those of P. quercivorus. Candida pseudovanderkliftii and C. vanderkliftii are assumed to be auxiliary ambrosia fungi of P. quercivorus.     

<Emphasis Type="Italic">Cambessedesia tiradentensis</Emphasis> (<Emphasis Type="Italic">Melastomataceae</Emphasis>), a new species from Brazil

Summary  A new and probably endemic species of Cambessedesia DC. is described from campo rupestre vegetation, as part of a floristic survey of Melastomataceae from the S?o José mountain range, Tiradentes District, Minas Gerais State, Brazil. Miscellaneous  Accepted for publication April 2008.     

<Emphasis Type="Italic">Flavobacterium koreense</Emphasis> sp. nov., <Emphasis Type="Italic">Flavobacterium chungnamense</Emphasis> sp. nov., and <Emphasis Type="Italic">Flavobacterium cheonanense</Emphasis> sp. nov., isolated from a freshwater reservoir

Taxonomic studies were performed on three strains isolated from Cheonho reservoir in Cheonan, Korea. The isolates were Gram-negative, aerobic, rod-shaped, non-motile, catalase-positive, and oxidase-positive. Colonies on solid media were cream-yellow, smooth, shiny, and circular. Phylogenetic analysis of the 16S rRNA gene sequences revealed that these strains belong to the genus Flavobacterium. The strains shared 98.6–99.4% sequence similarity with each other and showed less than 97% similarity with members of the genus Flavobacterium with validly published names. The DNA-DNA hybridization results confirmed the separate genomic status of strains ARSA-42^T, ARSA-103^T, and ARSA-108^T. The isolates contained menaqui-none-6 as the predominant menaquinone and iso-C_15:0, iso-C_15:0 3-OH, iso-Ci_15:1 G, and iso-C_16:0 3-OH as the major fatty acids. The genomic DNA G+C content of the isolates were 31.4–33.2 mol%. According to the phenotypic and genotypic data, these organisms are classified as representative of three novel species in the genus Flavobacterium, and the name Flavobacterium koreense sp. nov. (strain ARSA-42^T =KCTC 23182^T =JCM 17066^T =KACC 14969^T), Flavobacterium chungnamense sp. nov. (strain ARSA-103^T =KCTC 23183^T =JCM 17068^T =KACC 14971^T), and Flavobacterium cheonanense sp. nov. (strain ARSA-108^T =KCTC 23184^T =JCM 17069^T =KACC 14972) are proposed.     

<Emphasis Type="Italic">Elaphoglossum mickeliorum</Emphasis> (Dryopteridaceae), a new species of <Emphasis Type="Italic">Elaphoglossum</Emphasis> sect. <Emphasis Type="Italic">Polytrichia</Emphasis> from Peru

Elaphoglossum mickeliorum, a new species from the eastern slopes of the Peruvian Andes, is here described and illustrated. It belongs to E. sect. Polytrichia, which is characterized by the presence of subulate scales and absence of hydathodes on the sterile leaves of adult sporophytes. Herbarium specimens of this new species were first collected by Alwyn H. Gentry ca. 40 years ago, but these got readily confused with E. erinaceum and went undescribed since then. The new species differs from members of the E. erinaceum complex by having a nearly continuous band of planar, nonsubulate scales along the laminar margins of sterile leaves. Based on this character, E. mickeliorum resembles species such as E. glaziovii, E. ornatum, and E. scolopendrifolium. It differs from these by the presence of minute glandular hairs on petioles and costae. A distribution map and a figure with line drawings are also provided. For comparative purposes, the line drawing includes E. blepharoglottis, which is here illustrated for the first time.     

<Emphasis Type="Italic">Linaria khalkhalensis</Emphasis> (<Emphasis Type="Italic">Linaria</Emphasis> sect. <Emphasis Type="Italic">Linaria</Emphasis>, Scrophulariaceae), a new species from Iran

Summary   Linaria khalkhalensis Hamdi & Assadi is described as a new species from Azerbaijan and Guilan provinces (northern Iran), belonging to Linaria sect. Linaria. It is close to Linaria lineolata Boiss. and L. elymaitica (Boiss.) Kuprian., which it resembles in habit and vegetative features. However, floral and seed characters together with a distinctive geographical distribution, warrant recognition at the species rank. An illustration of the new species, a distribution map, scanning electron micrographs of seed and capsule surfaces, and an identification key are also included.     

<Emphasis Type="Italic">Bulbophyllum fendlerianum</Emphasis> (<Emphasis Type="Italic">Orchidaceae</Emphasis>), a new species from Venezuela

Summary   Bulbophyllum fendlerianum is newly described based on a collection of August Fendler in Venezuela, deposited at the Royal Botanic Gardens, Kew. It was previously confused with B. manarae, but differs significantly from the latter species in its petal and lip shape, particularly the callus.     

<Emphasis Type="Italic">Typhonium stigmatilobatum</Emphasis> (<Emphasis Type="Italic">Araceae</Emphasis> tribe <Emphasis Type="Italic">Areae</Emphasis>), a new species from Vietnam

<Emphasis Type="Italic">Fusarium matuoi</Emphasis> sp. nov. and its teleomorph <Emphasis Type="Italic">Cosmospora matuoi</Emphasis> sp. nov.

A group of Fusarium isolates from slime flux similar to F. aquaeductuum produced unique, strongly curved, aseptate, C-shaped conidia. They were found to be identical to F. splendens nom. nud. Dried specimens from which F. splendens was originally isolated were reexamined and characterized as a new species of Cosmospora. Cosmospora matuoi sp. nov. is proposed for the teleomorph, and Fusarium matuoi sp. nov. is proposed for its anamorph.     

<Emphasis Type="Italic">Trichomonascus petasosporus</Emphasis> sp. nov. and <Emphasis Type="Italic">Sympodiomyces indianaensis</Emphasis> sp. nov., two new members of the Saccharomycetales

Two new yeasts are described that were recognized as novel from nucleotide divergence in domains D1/D2 of 26S rDNA. The new species and their type strains are the following: Trichomonascus petasosporus NRRL YB-2092T (CBS 9602T), mating type a, NRRL YB-2093 (CBS 9603), mating type alpha, and Sympodiomyces indianaensis NRRL YB-1950T (CBS 9600T). Phylogenetic analysis placed the two new taxa, which are sister species, in the Sympodiomyces clade near Blastobotrys/Stephanoascus farinosus. Placement of Trichomonascus in the Saccharomycetales resolves the earlier uncertainties surrounding the classification of this morphologically unusual genus.     

<Emphasis Type="Italic">Paenibacillus bryophyllum</Emphasis> sp. nov., a nitrogen-fixing species isolated from <Emphasis Type="Italic">Bryophyllum pinnatum</Emphasis>

A nitrogen-fixing, endospore-forming bacterium, designated strain L201^T was isolated from the leaves of Bryophyllum pinnatum growing in South China Agricultural University. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain L201^T is affiliated with the genus Paenibacillus, and closely related to Paenibacillus albidus Q4-3^T (97.4%), Paenibacillus odorifer DSM 15391^T (97.3%) and Paenibacillus borealis DSM 13188^T (97.2%). The main fatty acids components was anteiso-C_15:0 (48.1%). The predominant isoprenoid quinone was MK-7. The major polar lipids were found to be diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol. The G+C content of strain L201^T was 43.9%. DNA–DNA relatedness between L201^T and the reference strain was 29.8%. Biological and biochemical tests, protein patterns, genomic DNA fingerprinting and comparison of cellular fatty acids distinguished strain L201^T from the closely related Paenibacillus species. Based on these data, the novel species Paenibacillus bryophyllum sp. nov. is proposed, with the type strain L201^T(=?KCTC 33951 ^T?=?GDMCC 1.1251 ^T).     

Specificity of <Emphasis Type="Italic">Anagyrus</Emphasis> sp. nov. nr. <Emphasis Type="Italic">sinope</Emphasis> and <Emphasis Type="Italic">Leptomastix dactylopii</Emphasis> for six mealybug species

In order to understand better non-target effect and potential uses, the host specificity of two parasitoid species (Anagyrus sp. nov. nr. sinope Noyes & Menezes and Leptomastix dactylopii Howard) (both Hymenoptera: Encyrtidae) for six mealybug species [Ferrisia virgata (Cockerell), Phenacoccus madeirensis Green, Phenacoccus solani Ferris, Planococcus citri (Risso),Pseudococcus longispinus (Targioni-Tozzetti) and Pseudococcus viburni (Signoret)] (all Hemiptera: Pseudococcidae) was studied through behavioral observations and laboratory rearing. The selected mealybug species represent major subfamilies and tribes of Pseudococcidae. Except for F. virgata, all mealybug species induced examinations by Anagyrus sp. nov. nr. sinope and L. dactylopii. Anagyrus sp. nov. nr. sinope was specific to P. madeirensis, which was the only mealybug species selected for oviposition and suitable for complete development of the parasitoid. No encapsulation of Anagyrus sp. nov. nr. sinope in P. madeirensis was observed. Leptomastix dactylopii accepted multiple species for oviposition, with the ranking of species preference as P. citri > P. viburni > P. longispinus > P. solani > P. madeirensis. Only P. citri, P. longispinus and P. viburni supported the development of L. dactylopii. Parasitoids developing in P. longispinus and P. viburni suffered from high encapsulation rates, while no encapsulation was observed when developing in P. citri. The results of this study suggest that Anagyrus sp. nov. nr. sinope is highly host specific. Leptomastix dactylopii, on the other hand, has a wider host range. The use of Anagyrus sp. nov. nr. sinope in a mealybug biological control program is limited to P. madeirensis and L. dactylopii to P. citri. The results presented in this study also lead us to question the accuracy of the reported host range of L. dactylopii, which include all six mealybug species tested.     

<Emphasis Type="Italic">Metschnikowia viticola</Emphasis> sp. nov., a new yeast species from grape

Two yeast strains, producing needle-shaped ascospores under suitable conditions, were isolated from grapes grown in Hungary. Based on these two strains, Metschnikowia viticola (type strain NCAIM Y.01705, CBS 9950, JCM 12561) is proposed as a new yeast species. Considering its phenotypic features, the restriction fragment patterns of 18S rDNA and the sequence of the D1/D2 domain of 26S rDNA, the proposed new species is closely related to Candida kofuensis.

<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.     

A new species of the genus <Emphasis Type="Italic">Triplophysa</Emphasis> (Nemacheilinae: Balitoridae), <Emphasis Type="Italic">Triplophysa jianchuanensis</Emphasis> sp. nov,from Yunnan,China

A new loach species, named Triplophysa jianchuanensis, has been recognized in collections from Jianchuan in Dali Prefecture, Yunnan, China. Triplophysa jianchuanensis can be distinguished from the other Triplophysa species by the following combination of characteristics: smooth skin, scaleless; lateral line complete; head long (26.7–29.8% of SL); eyes large (25.9–31.0% of dorsal head length); snout shorter than postorbital length (26.9–30.1% of HL); middle of lower lip interrupted and forming a pair of furrows; lower jaw spoon-like with obtuse edge; posterior chamber of air bladder completely degenerated; intestines short, bending in zigzag-shape behind stomach; pelvic-fin tip not reaching anus; caudal fin emarginate; branched rays of dorsal fin 7; branched rays of caudal fin 16. A key to the known species of Triplophysa from the Lancangjiang River is provided.
