Bemerkungen zu einigenStipagrostis-Arten (Gramineae) aus Afrika und Arabien

Summary A new species from Egypt (Sinai) and Arabia is described asStipagrostis multinerva H.Scholz. Stipagrostis arabiaefelicis Bor 1967 is a synonym ofSt. drarii (V.Täckholm)de Winter 1963 (Aristida drarii V.Täckholm 1941). The taxonomic status ofStipagrostis foexiana (Maire etWilczek)de Winter (Aristida obtusa subsp.pubescens Andreánszky) in North and South Africa is discussed. Furthermore some new data on taxonomy and distribution of the following species are recorded:Stipagrostis acutiflora subsp.algeriensis (Henrard) comb, nov. et stat. nov.,St. ciliata (Desf.)de Winter,St. lanata (Forsk.)de Winter,St. libyca (H.Scholz) comb, nov.,St. papposa (Trin. etRupr.)de Winter,St. raddiana (Savi)de Winter,St. shawii (H.Soholz) comb, nov., andSt. sokotrana (Vierhapper)de Winter.      

Taxonomic studies on new or critical fungi of non-pathogenic Onygenales 4

Three noteworthy taxa of soil-borne onygenalean fungi are described and illustrated:Kraurogymnocarpa trochleospora, comb. nov.,Kuehniella aurea, comb. nov., andNannizziopsis albicans. In addition,Aphanoascus boninensis, which was previously described as a new species, is considered to be a synonym ofUncinocarpus orissi.     

Microfungi on Cercocarpus

Camarosporellum cercocarpi sp. nov. is described from lesions onCercocarpus ledifolius and the genus is compared withCamarosporium andNeohendersonia. Neohendersonia kickxii (Westend.) comb. nov., type species of the genus is redescribed and illustrated. The genusSeptogloeum is reviewed and compared withPhloeospora, andPhloeospora cercocarpi (Bonar) comb. nov. (Septogloeum cercocarpi Bonar) is redescribed. Conidial ontogeny is stressed as a valuable taxonomic character to be used in distinguishing between genera.     

DNA relatedness among saturn-spored yeasts assigned to the generaWilliopsis andPichia

Saturn-spored species assigned to the generaWilliopsis andPichia were compared from extent of nuclear DNA complementarity. Of thePichia spp., four were recognized as distinct taxa:P. dispora, P. saitoi, P. zaruensis andPichia sp. nov. AmongWilliopsis spp., the following were accepted:W. californica, W. mucosa comb. nov.,W. pratensis, W. saturnus var.saturnus, W. saturnus var.mrakii comb. nov.,W. saturnus var.sargentensis comb. nov.,W. saturnus var.subsufficiens comb. nov. andWilliopsis sp. nov. The newPichia andWilliopsis species are described elsewhere. Moderate (36–68%) DNA relatedness was detected between the formerPichia sargentensis and varieties ofW. saturnus again demonstrating that nitrate assimilation is not a reliable criterion for separating yeast species.     

Two new species of Patellaria from India

Summary The paper deals with two new species ofPatellaria i.e.,Patellaria lantanae sp. nov. onLantana camara L. andPatellaria ipomoeae sp. nov. onIpomoea sp.Phoenix sylvestris Roxb. andAcacia arabica Willd. constitute new host records for the above species.     

Paleobotanical studies inFagaceae of the European Tertiary

A systematic reassessment of megafossil records ofFagaceae in Central Europe has been undertaken on the basis of leaf cuticular characters. The oldest representatives date back to the Eocene:Quercus subhercynica spec. nova,Dryophyllum furcinerve (Rossm.)Schmalh.,Trigonobalanopsis rhamnoides (Rossm.) gen. & comb. nov. In the Oligocene other members of extant genera appear:Quercus rhenana (Weyl. & Kilpp.)Knobloch & Kvaek,Fagus attenuata Goepp.,Lithocarpus saxonicus spec. nova. In the Neogene these ancient taxa (except inFagus lineage), are gradually replaced by deciduous species ofQuercus andCastanea. Trigonobalanus andCastanopsis are recorded by fruits (or wood) only.     

A revision of European taxa ofHyacinthoides sectionSomera (Hyacinthaceae) on the basis of multivariate analysis

Cluster analysis and principal components analysis were used to investigate patterns of morphological variation among specimens of European species of sect.Somera of the genusHyacinthoides (Hyacinthaceae). The results are clearly consistent with the existence of four species (H. italica, H. paivae, H. reverchonii andH. mauritanica). It is proposed that the latter be considered to comprise two subspecies,H. mauritanica subsp.mauritanica andH. mauritanica subsp.vincentina (comb. nov.). A key is presented, together with distribution maps for the five taxa.     

Synonymy of Etiennea Matile-Ferrero with Hemilecanium Newstead (Hemiptera: Coccidae), based on morphology of adult females, adult males and first-instar nymphs, and description of a new potential pest species from the Ryukyu Archipelago, Japan

The genus Etiennea Matile‐Ferrero is synonymized with Hemilecanium Newstead (Hemiptera: Coccidae). We base this decision on a morphological comparative study of adult females, adult males and first‐instar nymphs (crawlers), including a phylogenetic analysis. We recovered a sister group relationship between the type species of the two genera, Etiennea villiersi Matile‐Ferrero and Hemilecanium theobromae Newstead; that is, each was more closely related to the other than either was to other species in their respective genera. All species hitherto included in Etiennea are transferred to Hemilecanium: H. bursera (Hodgson & Kondo) comb. nov., H. cacao (Hodgson) comb. nov., H. candelabra (Hodgson) comb. nov., H. capensis (Hodgson) comb. nov., H. carpenteri (Newstead) comb. nov., H. cephalomeatus (Hodgson) comb. nov., H. combreti (Hodgson) comb. nov., H. ferina (De Lotto) comb. nov., H. ferox (Newstead) comb. nov., H. gouligouli (Hodgson) comb. nov., H. halli (Hodgson) comb. nov., H. kellyi (Brain) comb. nov., H. madagascariensis (Hodgson) comb. nov., H. montrichardiae (Newstead) comb. nov., H. multituberculum (Hodgson) comb. nov., H. petasus (Hodgson) comb. nov., H. sinetuberculum (Hodgson) comb. nov., H. tafoensis (Hodgson) comb. nov., H. ulcusculum (Hodgson) comb. nov., and H. villiersi (Matile‐Ferrero) comb. nov. Keys to the adult females of all 26 species and known adult males and first‐instar nymphs are provided. The adult males and first‐instar nymphs of H. theobromae Newstead and E. villiersi Matile‐Ferrero are for the first time fully described and illustrated. One new potential pest species of Hemilecanium, H. uesatoi Kondo & Hardy sp. nov., which was collected on three islands of the Ryukyu Archipelago, Japan, is described and illustrated based on the adult female, adult male and first‐instar nymph. We discuss evidence that H. uesatoi is a new introduction to the Ryukyu Archipelago. The first‐instar nymphs of Hemilecanium can be divided into two distinct morphological groups, the petasus group and the theobromae group.     

Relationships between species ofLeymus,Psathyrostachys, andHordeum (Poaceae,Triticeae) inferred from Southern hybridization of genomic and cloned DNA probes

We have used total genomic DNA as a probe to size-fractionated restriction enzyme digests of genomic DNA from a range ofTriticeae species from the generaLeymus Hochst.,Psathyrostachys Nevski, andHordeum L., and hybrids betweenHordeum andLeymus to investigate their taxonomic relationships. Genomic Southern hybridization was found to be an effective and simple way to assess the distribution and diversity of essentially species-specific and common, repetitive DNA sequences, and is hence especially useful in evolutionary studies. The DNA sequences ofH. vulgare seem to diverge substantially from those ofH. brachyantherum, H. lechleri, H. procerum, andH. depressum. The genome ofThinopyron bessarabicum shows little homology to those of theLeymus species investigated, confirming thatT. bessarabicum is not an ancestral genome inLeymus. Although the genomes ofLeymus andPsathyrostachys share substantial proportions of DNA sequences, they include divergent repeated sequences as well. Hybridization with a ribosomal DNA probe (pTa 71) showed that the coding regions containing structural genes encoding the 18 S, 5.8 S, and 26 S ribosomal RNA were conserved among the species investigated, whereas the intergenic spacer region was more variable, presenting different sizes of restriction fragments and enabling a classification of the species. The rye heterochromatin probe pSc 119.2 hybridized to DNA fromH. lechleri andT. bessarabicum, but not to DNA from the other species investigated.     

Taxonomic review of the genus Pseudostegania Butler, 1881, with description of four new species and comments on its tribal placement in the Larentiinae (Lepidoptera: Geometridae)

The genus Pseudostegania Butler is revised. In addition to the two species known, four species are described as new: P. lijiangensis sp. nov. from Yunnan Province, P. qinlingensis sp. nov. from Gansu and Shaanxi Provinces, P. zhoui sp. nov. from Sichuan Province (China) and P. burmaensis sp. nov. from Burma (Myanmar); two species are newly combined with Pseudostegania: P. distinctaria (Leech, 1897), comb. nov. and P. yargongaria (Oberthür, 1916), comb. nov. All the known species are redescribed and lectotypes are designated for P. defectata (Christoph, 1881), P. distinctaria and P. yargongaria. The generic characters, based on all species, are summarized. The tribal placement of Pseudostegania is discussed. Illustrations of moths and genitalia are presented.     

Some helicosporae from Hyderabad-II

Summary In this communication four species each ofHelicomyces Linder andHelicosporium Nees are reported.Helicomyces hyderabadense, Helicosporium indicum andH. nizamabadense are reported as new species.Helicomyces fuscopes Linder,H. lilliputeus Moore andHelicosporium Neesii Moore are first records to India.     

Taxonomic status of the species of the green algal genusNeochloris

Komárek has recently reviewed the various species assigned to the green algal genusNeochloris Starr (Chlorococcales, Chlorococcaceae) and removed those with uninucleate vegetative cells to a new genus,Ettlia. Watanabe & Floyd, unaware ofKomárek's work, also reviewed the species ofNeochloris and distributed them among three genera—Neochloris, Chlorococcopsis gen. nov., andParietochloris gen. nov.—on the basis of details of the covering of the zoospore and the arrangement of the basal bodies of the flagellar apparatus. This paper reconciles these two treatments and makes additional recommendations at the ranks of genus, family, order, and class.     

Taxonomy of Haplosporangium parvum

Summary A strain ofHaplosporangium parvum has been isolated from Italian soil. It has been comparatively studied with six North American and a Korean strain. Two American and the Italian strains are thermophilic (opt. about 35° C) while the other four grow better at temperatures around 20° C.The assimilation of nitrogen sources has been comparatively studied. In addition to peptoneH. parvum metabolizes urea and most aminoacids, whileH. bisporale assimilates peptone, leucine, alanine, glutamic acid and proline only. On the basis of N assimilation and thermophily, a key of the studied strain is established.A comparison ofH. bisporale withH. parvum, confirmed that the former species is a Phycomycete, while the latter is a Moniliaceous, aleuriosporic fungus. All the strains are feebly pathogenic, but the virulence of the Italian soil isolate is equal to that of the most virulent strains isolated from animal lungs (Alberta, Canada).The taxonomy ofH. parvum has been studied in relation to the more or less allied generaAleurisma, Glenosporella, Geomyces andStaphylotrichum.It is concluded thatH. parvum may be better classified as a new genus, and the monotypic genusEmmonsia withE. parva (Emm. etAshb.) n. comb. is proposed, although the entire group of aleuriosporaceous fungi needs revision.     

Heterostyly in species ofNarcissus (Amaryllidaceae) andHugonia (Linaceae) and other disputed cases

The hypothesis ofHenriques andFernandes that several Iberian species ofNarcissus (Amaryllidaceae) are tristylous is reconsidered. Contrary to the opinion ofBateman and most subsequent authors, we believe that the available evidence indicates that some populations ofN. triandrus andN. fernandesii, at least, are tristylous; other populations ofN. triandrus are distylous.Hugonia cf.penicillanthemum (Linaceae) from new Caledonia is distylous, but it remains possible that other species ofHugonia are tristylous. The disputed occurrence of heterostyly in S. African species ofBauhinia (Leguminosae),Cleome (Capparaceae) andAneilema (Commelinaceae), and inAgelaea (Connaraceae) is discussed.     

SULCOPYRENULA,A NEW PYRENOCARPOUS LICHEN GENUS (PYRENULACEAE,LICHENIZED ASCOMYCOTA)

Sulcopyrenula H. Harada gen. nov. is described. It differs from other genera ofPyrenulaceae by having longitudinally sulcate spores. The genus is represented by two species: S. canellae-albae (Fée) H. Harada comb. nov. and S. staurospora (Tuck.) H. Harada comb. nov. Both species have been previously reported from N. and S. America, and the latter species is now reported from Asia.     

Taxonomic review of Hemistola Warren, 1893 from China,with descriptions of seven new species (Lepidoptera: Geometridae,Geometrinae)

The genus Hemistola Warren from China is reviewed, and seven new species are described: H. viridimargo, sp. nov., H. glauca sp. nov., H. asymmetra sp. nov., H. arcilinea sp. nov., H. flavifimbria sp. nov., H. orbiculosoides sp. nov. and H. stueningi sp. nov. Two species, acyra and christinaria, are transferred from Hemistola to Maxates and Comostola, respectively: Maxates acyra comb. nov. and Comostola christinaria comb. nov. Including the 25 species previously known from China, a total of 32 species is now recorded. All Chinese species are redescribed. Generic characters based on all species are summarized. Illustrations of adults and genitalia are presented.     

Taxonomy,distribution, and status of gibbons (Hylobates) in Southern China and adjacent areas

Gibbons are small and arboreal apes restricted to southeastern tropical and southern subtropical regions in Asia. They are distributed from Assam in the northwest, eastward to south China and Vietnam, south through the Malay Peninsula to Sumatra, Borneo, Java, and the Mentawai Islands. Twenty-two genetically distinct populations of gibbons are generally recognized. Gibbons were once widely distributed in China; however, they are now primarily restricted to southern and southwestern Yunnan and Hainan Island. Their widest distribution and greatest species diversity is in Yunnan Province. Gibbons are rare in China and are now listed as a first class endangered species. Four gibbon species inhabit Yunnan Province in southern China. They areH. hoolock, H. lar, H. leucogenys, andH. concolor. There are three subspecies ofH. leucogenys: H. l. leucogenys, H. l. siki, andH. l. gabriellae. OnlyH. l. leucogenys inhabits China. Four subspecies ofH. concolor inhabit China. These areH. c. concolor, H. c. jingdongensis, H. c. furvogaster, andH. c. hainanus. The first three subspecies inhabit Yunnan andH. c. hainanus is found only on Hainan Island.H. lar yunnanensis is the subspecies ofH. lar in southern China.H. hoolock leucogenys is the subspecies ofH. hoolock in southern China.H. concolor jingdongensis, H. concolor furvogaster, andH. lar yunnanensis are all newly proposed subspecies byMa andWang (1986). The data on southern China gibbons presented here is based on an analysis of the skeletons and skins of 49 specimens held at the Kunming Institute of Zoology, Kunming, Yunnan.     

The genusBrachydesmiella from submerged wood in the tropics, including a new species and a new combination

During studies of fungi occurring on wood submerged in freshwater streams in the tropics, five species ofBrachydesmiella, namely,B. anthostomelloidea, B. biseptata, B. caudata, B. orientalis comb. nov., andB. verrucosa sp. nov., were collected. There are described and illustrated from natural substrata, wooden test blocks, and from pure culture, based mainly on collections made in Thailand.Brachydesmiella verrucosa differs from the other four species in having 3-celled, coarsely verrucose, ampoule-shaped conidia, with a long, thin, cylindrical, verruculose apical cell. A key toBrachydesmiella species is provided.     

Muribasidiospora — A new genus of the exobasidiaceae

Summary A new genus under the Exobasidiaceae namelyMuribasidiospora gen. nov.Kamat, M. N. &Rajendren, R. B. has been established to accommodate such species ofExobasidium producing muriform basidiospores in their life cycle. Accordingly the two species viz.Exobasidium hesperidium Maire andE. celtidis Ramakrishnan, T. S. & K. are proposed to be transferred to the new genus under new combinations.     

Zur taxonomischen Stellung und Nomenklatur vonMicropus longifolius (Compositae-Inuleae)

Zusammenfassung Die unter den NamenMicropus longifolius Boiss. etReut. bzw.Cymbolaena longifolia (Boiss. etReut.)Smoljan. gut bekannte Art wurde zuerst alsStylocline griffithii A.Gray beschrieben. Ihre taxonomische Stellung in bezug auf die GattungenMicropus undStylocline wird diskutiert. Es erscheint am richtigsten, die Art in eine eigene monotypische Gattung zu stellen, ihr korrekter Name ist dannCymbolaena griffithii (A.Gray)Wagenitz, comb. nov.

---

Summary The species usually known asMicropus longifolius Boiss. etReut. orCymbolaena longifolia (Boiss. etReut.)Smoljan. was described for the first time in 1873 asStylocline griffithii A.Gray. The taxonomic position in relation to the generaMicropus andStylocline is discussed. It seems most appropriate to regard this species as belonging to a monotypic genus. In this case its correct name isCymbolaena griffithii (A.Gray)Wagenitz, comb. nov.
