A revision of the genus Trixa Meigen （Diptera： Tachinidae）

The genus Trixa Meigen, 1824 is revised. Dexiotrix Villeneuve, 1936 and Trixella Mesnil, 1980, each of which was sometimes treated as a distinct genus, are treated as junior synonyms of Trixa Meigen. Two species from Sichuan and Yunnan, China, are described as new to science, viz. Trixa chinensis sp. nov. and T. chaoi sp. nov. T. alpina Meigen is treated as a junior synonym of T. caerulescens Meigen. T. nox (Shima) and T.pubiseta (Mesnil) are newly recorded from China. Males of T. pubiseta (Mesnil) and T.longipensis (Villeneuve) are described for the first time. Diagnoses, figures and a key to twelve species in Trixa are given.

During a recent re-examination of some Macromitrium specime ns from this region. A taxon closely related to species of the M. ferriei Card &; Ther. was found to be different from any known species of Macromitrium and is described here as a new species.......     

我国首次记录的微型硅藻——具刺原龙骨藻和伊岛棒杆藻及对其分类地位的讨论

Protokeelia is described as a new and rare pennate diatom genus in China. Its valve includes two parts： ventral valve and dorsal valve. The ventral valve is more or less convex or concave. The raphe runs in a distinct elevated and thickened siliceous ridge. In the internal valve, beneath the raphe are fibulae or fibulae clusters which connect the ventral and dorsal valves. One species, P. spinifera Round ＆ Basson, is observed in the water samples from a mangrove forest in Sai Kung, Hong Kong, China. Its main morphological features are described in this paper along with electron microscope （EM） photos. Morphological comparisons are also made among several allied species. In addition, a newly recorded species for China, Rhopalodia iriomotensis Kobayasi, Nagumo ＆ Tanaka, is discussed here. Because several key features observed in this species resemble those of some Protokeelia species, we suggest that it may actually represent a Protokeelia species.     

Autecology and conservation status of Magnolia sargentiana Rehder ＆ Wilson （Magnoliaceae） in the Dafengding region,southern Sichuan Province,China

This paper reports the first population ecology study of the endangered Magnolia sargentiana Rehder ＆ Wilson （Magnoliaceae）. Magnolia sargentiana is a protected species in China, but little is known about its present status in the field. In 2007 and 2008, we surveyed the population and conservation status ofM. sargentiana in the Provincial Mamize Nature Reserve and the National Meigu Dafengding Nature Reserve, Sichuan Province, southwestern China. Natural regeneration is poor because of unfavorable environmental conditions and anthropogenic disturbances. Flower buds and bark ofM. sargentiana are used in traditional Chinese medicine and their collection by local people over the period 1983-1994 has led to marked population declines. The collection of flower buds and bark is now banned, but hewing branches for firewood and grazing continues to have a negative impact on the recovery of M. sargentiana populations. To protect the species, we require a ban on hewing branches, closure of primary forests to reduce the impact of humans and ungulates, better education of local people, and increased awareness of wildlife conservation.

Contribution to the Cladonia mycota of Greece, including Cladonia graeca sp. nov.

From mid-elevation pine forest on the Aegean Sea island of Thasos 8 additional Cladonia species for the lichen mycota of Greece are reported.Most have a wide distribution in Europe and reach their southern limit in Greece.From schistose rock in the same area and on Evvia a new species is described,Cladonia graeca,which is probably related to C.macrophylla and C.decorticata but contains fumarprotocetraric acid instead of psoromic or perlatolic acid.     

A revision of Clematis sect. Atragene （Ranunculaceae）

Clematis sect. Atragene is revised in this paper based on the examination of a large number of herbarium specimens, extensive field observations, and morphometric analyses. Brief taxonomic history and geographical distribution of the section are given, the relationships among the species are discussed, and the evolutionary trends of some characters in the section are evaluated. The staminodes of the plants in this section may have evolved from the outer stamens with petaloid filaments and gradually disappearing anthers. Subsequently, they may have evolved in two different ways. One possibility is that the staminodes elongate and become lanceolate, as long as sepals, and their apices turn into attenuate. The other is that the staminodes are spathulate, but not elongating, as long as stamens, and their apices turn into retuse from obtuse and rounded. The evolutionary trend of sepals may be from thin to thick in texture, and the veins from non-prominent to prominent. As a result, five new series are established and nine species, two subspecies and nine varieties （including three new ranks） are recognized in this section. An identification key is provided, and each taxon is described and illustrated. Clematis sibirica and Clematis ochotensis are treated as subspecies of Clematis alpina due to their subtle differences and lack of, or few, overlapping distributions. Clematis fusijamana and Clematisfauriei are recognized as varieties of C. alpina ssp. ochotensis for the continuous variation of the velutinous strips on the sepal margins. Clematis iliensis is treated as variety of C. alpina ssp. sibirica for the continuous variation of leaf division types. Extensive variations in sepal color and basal caruncle size support degrading Clematis chiisanensis as a variety of Clematis koreana. The North American ser. Occientales may be primitive, whereas ser. Macropetalae may be the most advanced taxon in this section. Ser. Alpinae and ser. Koreanae are closely related to each other. However, the systematic position of ser.     

Musa chunii Hakkinen,a new species （Musaceae） from Yunnan,China and taxonomic identity of Musa rubra

Phylogenetic Analysis of Brine Shrimp （Artemia） in China Using DNA Barcodinge

DNA barcoding is a powerful approach for characterizing species of organisms, especially those with almost identical morphological features, thereby helping to to establish phylogenetic relationships and reveal evolutionary histories. In this study, we chose a 648-bp segment of the mitochondrial gene, cytochrome c oxidase subunit 1 （COI）, as a standard barcode region to establish phylogenetic relationships among brine shrimp （Artemia） species from major habitats around the world and further focused on the biodiversity of Artemia species in China, especially in the Tibetan Plateau. Samples from five major salt lakes of the Tibetan Plateau located at altitudes over 4,000 m showed clear differences from other Artemia populations in China. We also observed two consistent amino acid changes, 153A/V and 183L/F, in the COI gene between the high and low altitude species in China. Moreover, indels in the COI sequence were identified in cyst and adult samples unique to the Co Qen population from the Tibetan Plateau, demonstrating the need for additional investigations of the mitochondrial genome among Tibetan Artemia populations.     

A New Species of Trimeresurus Lacépède, 1804(Squamata: Viperidae) from Southwestern China,Vietnam, Thailand and Myanmar

The pit vipers of the genus Trimeresurus Lacépède, 1804 is one of the largest groups of Asian snakes, distributed from India to China and Indonesia. Recent surveys in Jiangcheng and Simao, Yunnan Province, China resulted in a new species previously allocated to T. albolabris. Combining morphological and molecular data, we describe it as Trimeresurus guoi sp. nov. The new species morphologically differs from T. albolabris in the yellow green ventral color; an indistinct ventrolateral line; the a bsence of a postocular stripe; the firebrickred iris; a dark red stripe on dorsal tail; hemipenes with relatively weak sparse papillae, reaching 23 rd subcaudal when unextruded. Molecularly, the new species forms a clearly divergent lineage(BPP 1.00/UFB 100). Uncorrected pairwise distances of mitochondrial gene Cyt b between the new species and other known species of the subgenus Trimeresurus range from 0.052(T. albolabris) to 0.071(T. insularis).     

中国-喜玛拉雅特有属——蓝钟花属的分类修订

Cyananthus Wallich ex Bentham, the only genus of Campanulaceae with superior ovary, is revised to clarify infrageneric relationships and phylogeny of the genus. Evidence obtained from the comparative gross morphology, anatomy, palynology, and karyomorpho-logy recommends a new infrageneric classification of the genus, recognizing 23 species, belonging to two subgenera, four sections and four subsections. One subgenus(Subgen. Mi-cranthus), one section(Sect. Suffruticulosi) and two subsections(Subsect. Flavi and Sub-sect. Lichiangenses)are described as new taxa. New combinations at sectional (Sect. Annui) and subsectional(Subsect. Stenolobi) ranks are also proposed. The genus Cyananthus is strictly distributed in the high mountains of China(Xizang, Yunnan and Sichuan), extending to Bhutan, Nepal and India (Kumaon-Garhwal, Assam and Sikkim), with altitudinal ranges from 2500 ~ 5300 m. It is observed that 13 species are endemic to SW China and only three species are endemic to the Himalayas( two species in Ne     

我国蝮属蛇类和尖吻蝮英文名称的建议

“Vipers“ is the English common name for more than 200 species of the family Viperidae. The so called “pit vipers“ is also the English common name for more than 150 species of the subfamily Crotalinae which have a “faclal pit“, an organ on each side of head which functions as a heat receptor. Of course, in countries where the people use English as the mother language there are English names for most snakes found in their own country. For example, the pit-viper species Agkistrodon contortrix is called “copperhead“, and Agkistrodon piscivorus is called “cottonmouth“ or “water moccasin“ in the USA. Also, another pit-viper, Agkistrodon bilineatus, is called “cantil“ by the people in Mexico and South America. In Japan, there has only one species belonging to the genus Glo3dius, i.e., Gloydius blornhoffii. According to its Japanese pronunciation, it has an English name by spelling of English alphabets as “mamushi“. Up to date, there are more than ten species recognized in the genus Gloydius. Among them , most are found in China. But there is no English common name especially for those species. After my detail studying, I certainly believe that there a Chinese word, “腹“ (according to Chinese pronunciation, it may be spelled by English alphabets as “Fu“) especially for the pit-viper species since 500 to 300 years B.C. During the following 2500 years, the snake name “Fu“ appeared in many ancient Chinese boaks dealing about dictionary (the “Ya“ course), drug boaks (Ben Cao), and even literature boaks or papers. So, the author of this paper used “腹“ as Chinese name for all the Gloydius species as well as for Deinagkistrodon acutus, because the latter was never included in the same genus. In this paper the author would suggest to use the English alphabet spelling “Fu“ plus “s“ (Fus) as an English name for the genus Gloydius, and “Fu “ as the English name of all the Gloydius species found in China and other places (excluding Gloydius blomhoffii found only in Japan, which still would keep its Japanese name “mamushi“). Besides, using “Sharp-snouted Fu“ as an English name of the genus Deinagkistrodon as well as species name of Deinagkistrodon acutus.
