A record of the Plain Tiger,Danaus chrysippus,in Turkey

Summary

In this publication, a subdivision of the genus Annenica O. Boettger, 1877 sensu Auct. is proposed. One result of our study is the recognition of the genus Sprattia O. Boettger, 1883 for most of the South Anatolian species of the former genus Armenica. The genus Astrogena Szekeres, 1970, which was synonymised by H. NORDSIECK (1975: 98) with Armenica is redefined and used as a subgenus of Armenica for some species. Extensive recent collections contain new species and subspecies of this genus, which are described here.     

Filibryum (Hypnaceae), a new moss genus with a new species from East Asia

Filibryum, a new genus of the family Hypnaceae, is described to include three species from East Asia. Filibryum ogatae and F. yakoushimae are transferred to it from the genus Glossadelphus, while F. deguchianum is a newly described species. The genus is distinguished by the absence of a central strand in the stem, prorate leaf cells, and heteroblastic and deciduous stem leaves. Molecular data suggest that the genus is closely related to Taxiphyllum and the phylogenetic position of the new genus in the Hypnaceae is supported by an approximately unbiased (AU) test.     

Molecular phylogeny of Alnus (Betulaceae), inferred from nuclear ribosomal DNA ITS sequences

The nuclear ITS region of 19 species of Alnus was amplified and sequenced. The inferred molecular phylogeny shows that all species of the genus Alnus form a monophyletic group close to Betula and that the fundamental dichotomy within the genus lies between the subgenera Alnaster and Gymnothyrsus, sensu Murai (1964). The subgenus Alnaster appears to be basal in the genus, based on archaism of morphological features, and branching close to the root of the trees due to low ITS divergence from genus Betula. The monophyly of the section Clethropsis is not supported by the present data: Alnus nepalensis is positioned in the subgenus Gymnothyrsus, away from A. nitida and A. maritima. Surprisingly, A. formosana sect. Japonicae is closely tied to A. maritima sect. Clethropsis, with which it shares few morphological traits, and is separate from A. japonica sect. Japonicae with which it shares many traits. An increase in substitution rate is noted in the group comprising A. formosana, A. maritima and A. nitida relative to the rest of the genus, which appears to have had, on the average, a very slow mutation rate. Alnus glutinosa, the designated type for the genus, appears to be representative of the genus both for morphological characters and evolutionary rate. North-East Asia is comforted in its position of origin of the genus since not only does it have the highest number of species and representatives in all deep branching lineages, there are also fewer transcontinental migrations when a North-East Asian ancestor is postulated than when a North American ancestor is postulated.     

On the Paleozoic bryozoans of the genus <Emphasis Type="Italic">Ascopora</Emphasis> Trautschold

Based on the study of the neotype and the astogeny of the type specimens of the species Ascopora nodosa (Fischer von Waldheim, 1837), the diagnosis and species composition of the genus Ascopora Trautschold, 1876 are emended. The genus Ascopora and three species out of the five included in this genus—A. nodosa (Fischer von Waldheim, 1837); A. sokolovae Schulga-Nesterenko, 1955; and A. latiaxis Schulga-Nesterenko, 1955—are described. A new genus, Tetrasella gen. nov., with the type species T. blanda sp. nov. is described. This genus comprises five species, transferred from the composition of the genus Ascopora. An emended diagnosis of the genus Ascoporella Krutchinina, 1986, is provided. This genus comprises nine species, of which two, A. lecta sp. nov. and A. mera sp. nov., are described as new species.     

Oriental bamboo leafhoppers: A new genus and two new species of Mukariinae (Hemiptera: Cicadellidae) from Southwest China and notes on related group

A new genus, Tiaobeinia n. gen., and two new species, T. bisubula n. sp. and T. emeiensis n. sp., breeding on bamboo in Southwest China, are described and illustrated. Based on the nature of the face, the apical veins of forewing and hindwing, the hind femur macrosetal formula, the valve, the subgenital plate, and the style, this genus should belong to the subfamily Mukariinae. The related genus Ratfronta Chen & Li 1997, placed previously in subfamily Nirvaninae, is noted in the present paper. A new combination, F. grandis (Ishihara 1961) n. comb., transferred from the genus Mohunia Distant, is proposed. Keys to the species of the new genus Tiaobeinia and the genus Flatfronta are provided. The importance of those groups as pests on bamboo is briefly discussed.     

Nervostroma, gen. nov. in the Sclerotiniaceae, the teleomorph of Cristulariella, and Hinomyces anam. gen. nov. to accommodate the anamorph of Grovesinia: reassessment of the genus Cristulariella

Taxonomy of the genus Cristulariella is revised, retaining Cristulariella (Crist.) depraedans as the type. Two new species, Crist. cercidiphylli and Crist. corni, are additionally described under the genus. The new anamorphic genus Hinomyces is erected to accommodate Botrytis (Cristulariella) moricola and Cristulariella pruni. A new genus and species, Nervostroma depraedans, is erected in the Sclerotiniaceae to accommodate the teleomorph of Crist. depraedans, with an additional species, Nervostroma cercidiphylli.     

Patellaria: A new genus in the Chenopodiaceae

Comparative taxonomic studies within the genus Beta have shown that the section Patellares is distinct and should be regarded as a new genus, Patellaria, with the type Patellaria webbiana. The transference of Beta patellaris to this genus requires a new specific name, P. cordata.     

Actinodontum,a new genus of Desmidiaceae (Streptophyta,Viridiplantae) from tropical Africa

A new desmid genus, Actinodontum Alfinito et Coesel, is described from mountain areas of tropical Africa. The newly described genus differs from the allied genus Actinotaenium by the presence of marked teeth at the base of each semicell that alternate with those on the other semicell. Morphology of the type species, Actinodontum lomaense (Alfinito et Mazzoni) Alfinito et Coesel, is dealt with in much detail. Cosmarium basituberculoides Bourrelly et Couté and Cosmarium elgonense Kusel-Fetzmann are transferred to the new genus. The geographical distribution of the genus Actinodontum is discussed.     

A new genus of broad-winged moths of the family Cryptolechiidae (Acryptolechia,Lepidoptera, Gelechioidea) from southeastern Asia

The new genus, Acryptolechia (Lepidoptera, Cryptolechiidae), with the type species Cryptolechia malacobyrsa Meyrick, 1921 is described. The differences between this species and the type species of the genus Cryptolechia, Zeller 1852 (C. straminella Zeller, 1852) are shown. The genus Meleonoma Meyrick, 1914 is the closest to the new one. In addition to the type species, the new genus includes Acryptolechia facunda (Meyrick, 1910) comb. n. from India and A. torophanes (Meyrick, 1935) comb. n. from China.     

Molecular phylogenetic relationships of China Seas groupers based on cytochrome <Emphasis Type="Italic">b</Emphasis> gene fragment sequences

The classification and evolutionary relationships are important issues in the study of the groupers. Cytochrome b gene fragment of twenty-eight grouper species within six genera of subfamily Epinephelinae was amplified using PCR techniques and the sequences were analyzed to derive the phylogenetic relationships of the groupers from the China Seas. Genetic information indexes, including Kimura-2 parameter genetic distance and T _S/T _V ratios, were generated by using a variety of biology softwares. With Niphon spinosus, Pagrus major and Pagrus auriga as the designated outgroups, phylogenetic trees, which invoke additional homologous sequences of other Epinephelus fishes from GenBank, were constructed based on the neighbor-joining (NJ), maximum-parsimony (MP), maximum-likelihood (ML) and minimum-evolution (ME) methods. Several conclusions were drawn from the DNA sequences analysis: (1) genus Plectropomus, which was early diverged, is the most primitive group in the subfamily Epinephelinae; (2) genus Variola is more closely related to genus Cephalopolis than the other four genera; (3) genus Cephalopolis is a monophyletic group and more primitive than genus Epinephelus; (4) Promicrops lanceolatus and Cromileptes altivelis should be included in genus Epinephelus; (5) there exist two sister groups in genus Epinephelus.     

A STUDY ON MINDARUS KOCH IN CHINA WITH DESCRIPTIONS OF NEW SPECIES AND NEW SUBSPECIES (HOMOPTERA: MIN-DARIDAE)*

Abstract This paper deals with the genus Mindam Koch from China. The phylogeny of the genus is discussed. M. keteleerifoliae is regarded as the most advanced species, M. obliquus and M. piceasuc-tus are more advanced than M. abietinus, M. japonicus and M. victoria. The origin centre of the genus may be in Europe and the differentiation centre of the genus may be in Hengduan Mountains Region of China. Geological distribution of the genus shows island-shaped pattern. Five species from China was described in this paper, including one new species, M. piceasuctus Zhang and Qiao, one new subspecies, M. abietinus triprimesensori Zhang and Qiao and one newly recorded species, M. abietinus abietinus Koch 1856. A key to the Chinese species of Mindarus is given. The specimens of five species from China are deposited in the Institute of Zoology, Academia Sinica.     

Evaluation of Lespedeza germplasm genetic diversity and its phylogenetic relationship with the genus Kummerowia

The genetic diversity of the genus Lespedeza is not well known and the phylogenetic relationship of Lespedeza with the genus Kummerowia is unclear. We report the first study in which polymorphic expressed sequence tag-simple sequence repeat (EST-SSR) markers derived from Medicago, cowpea and soybean were used to assess the genetic diversity of the USDA Lespedeza germplasm collection and clarify its phylogenetic relationship with the genus Kummerowia. Phylogenetic analysis partitioned 44 Lespedeza accessions into three main groups some of which were species-specific and eight subgroups. This data set revealed some misidentified accessions, and indicated that the two species in the genus Kummerowia are closely related to the genus Lespedeza. Morphological reexamination was used to correct the misidentified accessions within the genus Lespedeza. Our results demonstrated that phylogenetic analysis with morphological reexamination provides a more complete approach to classify accessions in plant germplasm collection and conservation.     

A new genus of Entiminae from North Africa,supported by a phylogenetic analysis (Coleoptera: Curculionidae: Entiminae)

The genus Holcophloeus gen. nov. is here proposed to include Trachyphloeus cruciatus Seidlitz, 1868, and two new species native to North Africa, based on a phylogenetic analysis and an evaluation of the diagnostic characters. The taxonomic position of Holcophloeus in relation to the tribes Trachyphloeini Lacordaire, 1863, and Holcorhinini Desbrochers, 1898, is discussed, and the new genus is attributed to the Holcorhinini. Holcophloeus laurae sp. nov. from south‐eastern Morocco and Holcophloeus weilli sp. nov. from northern Libya are described and illustrated and a key to the species of the new genus is given. The lectotype of Trachyphloeus cruciatus Seidlitz, 1868, is designated. The genus Massimiellus Borovec, 2009, is transferred from Trachyphloeini to Holcorhinini. © 2013 The Linnean Society of London     

A new species of Clausia (Copepoda, Poecilostomatoida, Clausiidae) associated with the polychaete Arenicola brasilliensis Nonata in Korea

A new species of the genus Clausia associated with the polychaete Arenicola brasilliensis Nonata is described from intertidal sands in Korea. The new species, as a primitive member of the genus, has a large, non-transformed body and fully segmented rami on legs 1–4. This is the second record of Clausiidae in the Far Eastern seas. The genus Doviella Rocha, originally placed in the Clausidiidae, is synonymized with the genus Clausia in the Clausiidae.     

Beiträge zur Kenntnis der Sippenstruktur des Genus Parabarium Pierre ex Spire (Apocynaceae)

The genus Parabarium is clearly separated from the other genera of the subtribe Urceolinae by different characters. The inflorescences of their taxa are heterocladical pleiothyrses, trunk synflorescences, or pleiochasiums. Further morphological and anatomical investigations deals with flower buds, leaves, pollen grains, fruits, seed, and other parts of the plants. Basing on the character analysis resulting from this the genus Parabarium is divided into two subgenera with two sections and two subsections enclosing 16 species. Two of the latter are described as news, further two varieties are set up as new ones. Two species are transferred from the genus Ecdysanthera into the genus Parabarium. Further three Parabarium species are inserted, and some more taxonomical corrections are made. — The possible relations within the genus Parabarium are made. Based on these results P. micranthum and therefor the subsection Parabarium (subgenus Parabarium) have to be regarded as the more original ones in face of P. quintaretii and the subgenus Pleiochasium. The section Burmanicum of the subgenus Parabarium has an exceptional position within the genus     

On the Taxonomy of Mrazekidae: Resurrection of the Genus Bacillidium Janda, 192812

ABSTRACT. This paper reviews the taxonomy of the microsporidia of the family Mrazekidae Léger & Hesse, 1922, based on reexamination of slides in the collection of Prof. O. Jirovec, Prague, and discusses the available type material of Mrazekia argoisi and Bacillidium criodrili. Mrazekia argoisi differs prominently from the other species, and the genus Mrazekia is restricted to this species. The aberrant cytology and development exclude the species from the phylum Microspora. The genus Bacillidium is resurrected for the type species B. criodrili and for four other species. The genus Jirovecia is retained, and five species are transferred to this genus. A new family is erected for Bacillidium and Jirovecia. As B. criodrili does not exhibit octosporoblastic, pansporoblastic sporogony, the recent taxonomic treatment of the genus Bacillidium by Issi is rejected. Mrazekia jiroveci Sprague, 1977, the new name for B. limnodrili Jirovec, 1936, is rejected.
