A New Species of the Genus Trimeresurus from Southwest China(Squamata:Viperidae)

Species from the Trimeresurus popeiorum complex(Subgenus: Popeia) is a very complex group. T. popeiorum is the only Popeia species known from China. During the past two years, five adult Popeia specimens(4 males, 1 female) were collected from Yingjiang County, Southern Yunnan, China. Molecular, morphological and ecological data show distinct differences from known species, herein we describe these specimens as a new species Trimeresurus yingjiangensis sp. nov Chen, Ding, Shi and Zhang, 2018. Morphologically, the new species distinct from other Popeia species by a combination of following characters:(1) dorsal body olive drab,without cross bands on the scales;(2) a conspicuous bicolor ventrolateral stripe present on each side of males, first row of dorsal scales firebrick with a white ellipse dot on posterior upper part in male, these strips absent in females;(3) eyes firebrick in both gender;(4) suboculars separated from 3rd upper labial by one scale on each side;(5) ventrals 164–168(n = 5);(6) MSR 21.     

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).     

A New Species of Japalura(Squamata,Agamidae) from the Nu River Valley in Southern Hengduan Mountains,Yunnan, China

A population of Japalura from Yunnan Province, China, previously assigned to Japalura splendida, is described as a new species. The new species has been recorded between 1 138–2 500 m in the Nu River drainage between the towns of Liuku and Binzhongluo, and on the lower western slopes of the Nushan and eastern slopes of the Goaligongshan. The new species can be distinguished from other species of Japalura, except J. dymondi, by the following combination of characters: exposed tympani, prominent dorso-lateral stripes, and small gular scales. It is very similar with but differs from J. dymondi by having smooth or feebly keeled dorsal head scales, three relatively enlarged spines on either side of the post-occiput area, strongly keeled and mucronate scales on occiput area and within the lateral stripes, back of arm and leg green, higher number of dorsal-ridge scales(DS) and fourth toe subdigital scales(T4S). A principal component analysis of body measurements of adult male specimens of the new species and J. dymondi showed principal component 1 loading highest for upper arm length, fourth toe length and snout to eye length and principal component 2 loading highest for head width, head length and fourth toe length.     

Late Pliocene diversity and distribution of Drynaria(Polypodiaceae) in western Yunnan explained by forest vegetation and humid climates

The palaeodiversity of flowering plants in Yunnan has been extensively interpreted from both a molecular and fossil perspective. However, for cryptogamic plants such as ferns, the palaeodiversity remains poorly known. In this study, we describe a new ferny fossil taxon, Drynaria lanpingensis sp. nov. Huang,Su et Zhou(Polypodiaceae), from the late Pliocene of northwestern Yunnan based on fragmentary frond and pinna with in situ spores. The frond is pinnatifid and the pinnae are entirely margined. The sori are arranged in one row on each side of the primary vein. The spores have a semicircular to bean-shaped equatorial view and a tuberculate surface. Taken together with previously described fossils, there are now representatives of three known fossil taxa of Drynaria from the late Pliocene of western Yunnan.These finds suggest that Drynaria diversity was considerable in the region at that time. As Drynaria is a shade-tolerant plant, growing preferably in wet conditions in the understory of forests, its extensive existence may indicate forest vegetation and humid climates in western Yunnan during the late Pliocene.This is in line with results from floristic investigations and palaeoclimatic reconstructions based on fossil floras.     

A NEW SPECIES OF THE GENUS EUCHORTHIPPUS TARB.FROM CHINA(ORTHOPTERA:ACRIDIDAE)

A new species Euchorthippus fusigeniculatus, collected from Changbai Mountains, Jilin Province has been described and illustrated. This new species is allied to Eu. cheui Hsia, but differs from the latter in: 1) lateral carinae of the pronotum weakly incurved in the prozona, 2) the hind femora with dark knees, 3) the sides of supra-anal plate in the male with brown carinae.

圣海伦斯火山和高山植被

 Mt. St. Helens is an active volcano on the western flank of the Cascade: range in the southwestern Washington State, USA. It is located at lat. 46˚00′—46˚30′N, long 121˚52′—122˚40′W.We had investigated the alpine vegetation at Pine Creek, Butte Camp on Mt. St. Helens for three times, totaling ten days during August and eptember of 1983.The volcano had erupted sending out much pyroclastic, pumice and lava, which devdstated the vegetation around the crater. They not only mechanically destroyed plants tissue, but also buried entirely or partly of the plants.The radiant heat from the volcanic eruption caused the melting of ice and snow, creating huge mudflows, which estroyed and buried vegetation. The high temperture from direct radiant heat incinerated and scorched all the plants. On the other hand, the higher the elevation is, the stronger the wind and the lower the temperture; also snow was present on the alpine range, and this provided a lee for plants, and consequently some plants survived, and new ones row out of the ground. The alpine vegetation on Mt. St. Helens bears both the characteristic of alpine plants and the brand of volcanic activities: vegetation is sparse, species composition of plants limited, structure of community simple, production low and vegetation propagation being the main type of vegetative reproduction.The different types of lpine vegetation grow in different habitats: The community of Luekea pectinata grow in places covered by ice and snow; the community of Polygonum newberryi, Eriogonum pyroleafolium in localities covered by mudflow; the community of Phyllodace empetriformis on slopes of steep rocks and the community of grasses and sedges on low hills and plains. Hese are the four main communities on Mt. St. Helens. The recovery and succession of the alpine vegetation has been discussed. There are two types of succession, the primary and the secodary, with the secondary being the main one.Finally, the paper has analysed the reason why no forest occurs, on Mt. St. Helens. We think that it is a result of the ctive period of the volcano and that the climate conditions are favouable for forest. Also, we have suggested that some herbaceous plants be sown as soon as possible for they can accelerate the recovery of vegetation, and prevent the runoff of soil and water.     

A New Subspecies of Garrulax canorus——Garrulax canorus mengliensis

In our recent studies, a new subspecies of Garrulax canorus has been found in the southwestern and western part of Yunnan Province. Garrulax canorus mengliensis, subsp. nov. Holotype Adult male(Field number 620672); type locality: Menglian, Yunnan, alt. 940 m., Dec. 11, 1962. Allotype Adult female (Field number 587); type locality: Mengla, Xishuangbanna, Yunnan, alt. 900 m., Jan. 17, 1960.

A NEW GENUS OF HIODONTIDAE FROM LUOZIGOU BASIN, EAST JILIN

<正> Manchurichthys (Saito, 1936) has been, for a long time, the only representative of fossil vertebrate known from the Oil-bearing member of Dalazi Formation, Luozigou Basin, East Jilin. Since 1978, some new materials have been collected there by the Regional Geological Brigade of Jilin Province and the present author. Two more forms of fossil fishes are not known to occur in the rocks of this section. One is Sinarnia luozigouensis (Li, 1984) which is referred to Amiiformes; the other, Yanbiania (gen. nov.), is described in this paper and included in the osteoglossomorphan family Hiodontidae.     

A new species of sisorid catfish of the genus Exostoma from the Salween drainage,Yunnan, China

A new species of the sisorid catfish genus Exostoma Blyth,1860 was collected from two hill-stream tributaries of the Nujiang (Salween River) drainage in Gaoligong Mountain,south-western Yunnan Province,China from 2003 to 2006 and from two tributaries of the Salween River in Cangyuan County,Lingcang Prefecture,Yunnan Province,China (in 2007) and in Yongde County,Lingcang Prefecture,Yunnan Province,China (in 2015).Exostoma gaoligongense sp.nov.is the 10th species of the genus and is most similar to E.vinciguerrae in morphology but can be distinguished by pelvic fin reaching anus vs.not reaching;maxillary barbels just reaching or slightly surpassing pectoral-fin origin vs.surpassing pectoral-fin origin or even reaching posterior end of gill membrane;abdominal vertebrae 23-25 vs.25-27;length of dorsal fin/dorsal to adipose distance 90.3％-287.0％ vs.59.2-85.7.A key to Exostoma spp.is provided.

巨蟹蛛一种畸形雄性触肢器记述

During examination of spider material in the Institute of Zoology,Chinese Academy of Sciences (IZCAS),one male specimen came to our attention,which showed a unique anomaly in its palp.The morphology of this specimen is documented and suggestions for further investigations are given.Material. 2 males,Zhangjiajie National Park (29 08°N,110.29°E)[reared to adult,leg.LI Shu Qiang];deposited in the Institute of Zoology,Chinese Academy of Sciences,Beijing:Araneae,Sparassidae#89.One of the males has both palps intact and belongs to a Sinopoda species,which has yet to be determined.In the other specimen only the left palp is present in a deformed state.From size and color of both specimens,it could be possible that both are conspecific.Morphology. The anomalous morphology is limited to the palpal tarsus and to the retrolateral tibial apophysis (RTA).All remaining parts of the palp show a normal expression of morphological characters(e.g.spination,size,shape).The RTA is deformed in a way as recorded for e.g.Erigone atra (Jaeger, 1995),i.e.its size is reduced and its shape is different in comparison with the intact specimen.The main anomaly refers to the bulb,on the ventral side of the male tarsus.Usually,the bulb of sparassids composed of two sclerotized parts,tegulum and subtegulum,both separated by membranous parts,the haematodochae(cf.Yin et al.,1983).The basal haematodocha connects the subtegulum to the cymbium,the dorsal part of the tarsus.The cymbium bears hairs and contains nerves,whereas the bulb does not.In Sinopoda spp.embolus and conductor arise from the tegulum (Jaeger, 1999).A sperm duct extends from a distal opening on the embolus to the inner part of tegulum and subtegulum.     

Molecular Phylogeny Supports the Validity of Polypedates impresus Yang 2008

The taxonomy of the Asian tree frogs of the Polypedates leucomystax complex, a group of widespread and morphologically similar species, is very controversial. To ascertain the taxonomic status of these species, we investi- gated the historical relationships among representative samples based on ～ 2 kb of nucleotide sequences from the mitochondrial 12S rRNA, tRNAvaline, and 16S rRNA genes. Our phylogeny resolved five well supported lineages(A, B, C, D and E) in the P. leucomystax complex. Polypedates impresus from Yunnan, China, Polypedates cf. mutus and Polypedates cf. megacephalus from Guangxi and Yunnan, China, and Laos constructed Clade C, which is monophyletic. In order to recognize the unique position of this clade, we considered P. impresus in Clade C as a valid species. Following our phylogeny, Chinese Polypedates, corresponding to the other four clades, should include four species: P. mutus(Clade A); P. braueri(Clade B); P. impresus(Clade C) and P. megacephalus(Clade D). P. leucomystax(Clade E) is mainly distributed in the Malaysia, Indonesia and Philippines.     

Cloning,Characterization and Primary Function Study of a Novel Gene,Cymg1,Related to Family 2 Cystatins

Cystatins are cysteine proteinase inhibitors,We found two expression sequence tags (ESTs),CA463109 and AV042522,from a mouse testis library using Digital differential display (DDD).By electricalhybridization,a novel gene,Cymgl(GenBank accession No.AY600990),which has a full length of 0.78 kb,and contains four exons and three introns,was cloned from a mouse testis eDNA library.The gene is locatedin the 2G3 area of chromosome 2.The full eDNA encompasses the entire open reading frame,encoding 141amino acid residues.The protein has a cysteine protease inhibitor domain that is related to the family 2cystatins but lacks critical consensus sites important for cysteine protease inhibition.These characteristicsare seen in the CRES subfamily,which are related to the family 2 cystatins and are expressed specifically inthe male reproductive tract.CYMG1 has a 44%(48/108)identity with mouse CRES and 30%(42/140)identity with mouse cystatin C.Northern blot analysis showed that the Cymgl is specifically expressed inadult mouse testes.Cell location studies showed that the GFP-tagged CYMG 1 protein was localized in thecytoplasm of HeLa cells,lmmunohistochemistry revealed that the CYMG1 protein was expressed in mousetestes spermatogonium,spermatocytes,round spermatids,elongating spermatids and spermatozoa.RT-PCRresults also showed that Cymgl was expressed in mouse testes and spermatogonium.The Cymgl expressionlevel varied in different developmental stages:it was low 1 week postpartum,steadily increased 2 to 5 weekspostpartum,and was highest 7 weeks postpartum.The expression level at 5 weeks postpartum was main-tained during 13 to 57 weeks postpartum.The Cymgl expression level in the testes over different develop-mental stages correlates with the mouse spermatogenesis and sexual maturation process.All these indicatethat Cymgl might play an important role in mouse spermatogenesis and sexual maturation.

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
