Based on a combination of morphology and molecular data of ribosomal DNA genes,a new diatom genus Lineaperpetua gen.nov.Yu,You,Kociolek&Wang is described.The features that help define Lineaperpetua at the level of genus include:a tangentially undulated valve face;continuous cribra areolae on the valve interior consisting of pores arranged as strips;single rimoportula located inside the ring of marginal fultoportulae.Additionally,phylogenetic analysis based on nuclear small subunit(SSU)rDNA sequences and nuclear large subunit(LSU)rDNA gene placed the three strains of L.lacustris in a single,monophyletic clade at a considerable sequence distance from the other genera(Thalassiosira,Conticribra,Planktoniella,Shinodiscus,and other genera)belonging to Thalassiosirales.Despite the similarities with some species of Thalassiosira,Conticribra,and Spicaticribra,the suite of features found in Lineaperpetua differentiate it from these other genera.These molecular data and morphological characters suggest an affinity of the new genus to the Thalassiosiraceae. 展开更多

During our investigation of diatom biodiversity in Xizang,two species exhibited unique morphological features discriminative from all previously known genera.Herein we describe these two species and describe as new the genus,Spargeria gen.nov.The new genus features narrow to wide rectangular valves,narrow valve mantles,filiform raphe branches that occur on the valve face only,terminal raphe fissures straight or slightly deflected to same side,bow-tie shaped central areas,chambered striae present on the valve face only,being absent from the mantle,wider striae near the axial area and very narrow near the margin,multiseriate striae with small and round areolae that are occluded externally.Comparatively,Spargeria zhuii sp.nov.has larger and robust valves,radiate striae,with one divergent stria near the apices,while Spargeria chenia sp.nov.is smaller,with narrow valves,striae slightly radiate in the middle,becoming convergent or parallel near apices.This new genus belongs to the family Pinnulariaceae,and it was compared and contrasted with other genera of this family.Our work suggests the need for continued studies to document the biodiversity of diatoms in Xizang. 展开更多

Chinese medicine has a long history in the United States, dating back to its colonial period and extending up to the present. This essay focuses on the earliest generation of practitioners of traditional Chinese medicine in the United States. Although acupuncture is the modality most commonly associated with Chinese medicine in today's medical marketplace, up until the 1970s, Chinese healers in the United States typically specialized in herbalism. Well before mass emigration from China to the United States began, Chinese material medica crossed the oceans, in both directions: Chinese medicinal teas and herbs came west while Appalachian ginseng went east. Beginning in the 1850s, Chinese immigrants came to the United States and transplanted their health practices, sometimes quite literally by propagating medicinal plants in their adopted home. Over time, Chinese doctors learned how to sell their services to non-Chinese patients by presenting herbalism as “nature's remedies.” 展开更多

An interesting group of cymbelloid diatoms was collected from lakes in Yunnan Province,China,and observations on their valve morphology made using light and scanning electron microscopy.These cymbelloid species all have apical pore fields,slit-like areolae,and areolar occlusions,and they all lack of stigmata.In this paper we propose the new genus Qinia gen.nov.for these taxa and describe them as new:Q.lashii sp.nov.,Q.aequalis sp.nov.,and Q.daliensis sp.nov.The genus Qinia gen.nov.has lanceolate valves asymmetrical about their apical axes,raphe located in the middle of valve,distal raphe ends bent to the dorsal margin that bisects the apical pore fields(APFs),no stigmata,areolae with slit-like external openings and projections occluding the areolar openings internally.This genus resembles the genus Cymbella in the presence of APFs,but differs from Cymbella by a lack of stigmata,and by having external distal raphe ends that bisect the apical pore fields.Like Reimeria,the external distal raphe ends bisect the lobes of the APF,but Qinia species differ from Reimeria in that they have no stigmata and the distal raphe ends are deflected dorsally,not ventrally.Comparisons were made between Qinia and other cymbelloid genera whose members possess apical pore fields.Features that distinguish each species of the new genus are also discussed. 展开更多

Despite continuous studies on the cryptic diversity of the Diploderma flaviceps complex in Southwest China for the pastdecade, little attention has been given to other widespreadcongeners in China. Combining both morphological and phylogenetic data, we describe a new species of Diplodermafrom populations identified previously as D. dymondi in thelower Yalong River Basin in southern Sichuan Province. Thenew species is morphologically most similar to D. dymondiand D. varcoae, but it can be differentiated by a considerablegenetic divergence and a suite of morphological characters,including having taller nuchal crest scales, smaller tympana,and a distinct oral coloration. Additionally, we discuss otherputative species complexes within the genus Diploderma inChina. 展开更多

A new species of the agamid genus Japalura is described based on 15 specimens from the upper Lancang(Mekong) Valley of eastern Tibet, PR China. Populations of the new species, Japalura vela sp. nov., were previously recognized as J. flaviceps. The new species is morphologically most similar to J. batangensis, J. micangshanensis, J. variegata, and J. zhaoermii, but is distinguished from the four species and all remaining congeners by the following combination of morphological characters: 1) small adult size(SVL 56–69 mm in males, 59–66 mm in females); 2) ratio of tail TAL/SVL 1.85–2.06; 3) ratio of hind limb HLL/SVL 0.72–0.81; 4) T4 S 24 or 25; 5) concealed tympanum; 6) transverse gular fold present; 7) gular pouch present; 8) axillary fold present; 9) a pronounced, continuous, sail-like vertebral crest along length of body in males; 10) ground dorsal coloration black in males; 11) distinct gray transverse streaks on dorsal surface of head; 12) black radiated streaks around eyes; 13) distinct, black vermiculate stripes on ventral surface of head in both sexes; 14) a strongly jagged dorsolateral stripe from neck to base of tail on each side of vertebral crest in males; and 15) absence of gular spots in both sexes. General distribution patterns of the genus in the Hengduan Mountains region are also discussed. 展开更多

While considerable progress has been made in the taxonomic studies of the genus Lycodon in Asia,questions remain to be clarified regarding the taxonomy of certain groups,particularly those containing species in China.Not only do many regions in China remain overlooked by herpetologists,resulting in the possibility of undiscovered new species,but the surveyed areas also have suspicious records of recognized congeners that require taxonomic confirmations.Combining both morphological and genetic data,we tackle these outstanding issues in the taxonomy of Lycodon in China.In particular,we discover two new species of Lycodon:one from the previously neglected hot-dry valley in the northern Hengduan Mountain Region close to Tibet,and another recluse and cryptic species from the L.fasciatus complex in the downtown park of a major city in southern Sichuan Province.Additionally,we clarify the distribution of L.septentrionalis in China and resurrect and elevate its junior synonym subspecies,Dinodon septentrionale chapaense,as a full,valid species,and we synonymize the recently described L.namdongensis to the resurrected L.chapaensis comb.nov..Lycodon chapaensis comb.nov.thus represents a new national record of reptilian fauna of China.Lastly,based on literature review,we also correct some of the erroneous records of L.fasciatus and L.ruhstrati in China,point out remaining taxonomic issues of the genus for future research,and update the dichotomous key and distribution of the 20 species of Lycodon currently recorded from China. 展开更多

A new species of natricine snake of the Southeast Asian genus Opisthotropis GUnther, 1872 is described from western Hunan Province of China based on both mitochondrial DNA and morphological data. The new species is morphologically most similar and genetically most closely related to O. cheni Zhao, 1999 and O. latouchfi (Boulenger, 1899), but possesses considerable genetic divergence (p- distance 5.1%-16.7%) and can be differentiated from all other congeners by a combination of the following morphological characters: (1) body size large (total length 514-586 mm) and strongly built; (2) dorsal scale rows 17 throughout, feebly keeled anteriorly and moderately keeled posteriorly; (3) ventral scales 147-152, subcaudal scales 54-62; (4) preocular absent, Ioreal elongated and touching orbit; (5) supralabials 8-9, fifth and sixth entering obit; (6) anterior temporals short, length 1.74-2.04 times longer than width; (7) maxillary teeth subequal, 28-30; (8) dorsal surface of head with distinct irregular yellow stripes and markings edged with ochre; (9) body with clear black and yellow longitudinal streaks, partly fused to several lighter patches or thicker stripes anteriorly; and (10) venter pale yellow, with asymmetric blackish speckles along outer margin.

Due to a paucity of surveys in northern Indochina and lack of international collaborations among neighboring countries, recognized distributional ranges for many amphibian and reptile species end at the political borders for some countries, despite seemingly continuous suitable habitat spanning the region. Combining both morphological and genetic data, we report the first discovery of Japalura chapaensis, a rare agamid lizard believed previously to be endemic to northern Vietnam only, along the border region of southeastern Yunnan Province, China. To facilitate future research on the genus Japalura sensu lato in Indochina, we provide detailed descriptions of additional specimens of this rare species, including the first description of coloration in life and an expanded diagnosis, and discuss the species boundary of J. chapaensis with respect to its congeners. 展开更多

Although landscape features such as mountains and rivers are recognized often as limiting factors to amphibian dispersal and gene flow, a limited number of studies have investigated such patterns across Southeast Asia. A perfect example of this is Thailand, located in one of the world's biodiversity hotspot regions. Thailand represents the corridor between mainland Asia and the Sunda Shelf, a famous and widely recognized biogeographic region, and yet there are few studies on the genetic structure among populations of amphibian species distributed across Thailand. The Southeast Asian tree frog, Chiromantis hansenae has been reported to possess a geographic range that is restricted to Thailand and, presumably, Cambodia~ Here, we investigate phylogenetic relationships among C. hansenae populations using partial sequences of the mitochondrial 16S rRNA gene and nuclear POMC gene. Our results reveal two distinct evolutionary lineages within C. hansenae populations in Thailand. The genetic divergence among populations between these two clades is considerable, and results support inter-population divergence, and high genetic differentiation (pairwise FsT = 0.97), between two localities sampled in western Thailand (TK1 and TK2), separated from each other by 40 kilometers only. The results suggest that landscape features across Thailand may have a profound impact on patterns of diversification in the country, underscoring the urgent need for fine-scale investigations of genetic structure of endemic and "widespread" species. 展开更多

A new species of the genus Liurana Dubois, 1986 is described from Medog County, Tibet, China, based on morphological and molecular data. The new species can be differentiated from all other congeners by the following combination of characters:(1) head wider than long;(2) tympanum distinct and large;(3) hindlimb long, tibiotarsal articulation beyond tip of snout when adpressed;(4) belly with flat tubercles, cloacal region with small tubercles;(5) transverse bands distinctly on dorsal limbs, four bands on thigh and three on tibia;and,(6) dark brown marbled patterns or speckles on white bel y. Here, we also discuss the distribution pattern of Liurana in the East Himalaya region, the role of the Yarlung Tsangpo River in the speciation and genetic isolation of congeners, the direct developmental mode of reproduction, and the two different ecotypes of the genus.Lastly, we provide conservation recommendations for the genus in southeastern Tibet. 展开更多

Poorly preserved tracks have limited ichnotaxonomic or biotaxon utility,but may reveal useful information about the paleoenvironment,behavior and track taphonomy.Eight mostly parallel to sub parallel trackway segments(T1–T8)were registered on a truncation surface in the Lower Cretaceous Luohe Formation of Shaanxi Province.These attest to the passage of several bipeds,probably all theropods,in a paleo-contour-parallel,south-north direction in an arid setting.Quality of preservation in these trackways is poor,but notably superior in two additional trackways(T9–T10)on a foreset surface.Trackway T9 indicates a didactyl trackmaker,probably a deinonychosaurian,heading north to south.This is the 13th report of deinonychosaurian tracks from the Lower Cretaceous of China.If any or all the eight south-north oriented trackway segments represent continuations of other segments in the same trackways,the total number of individual trackmakers heading in this direction may have been as lowas three.Although the trackway pattern and sedimentological evidence could indicate a physically controlled pathway influencing the direction taken by these trackmakers,the possibility that the trackways also represented small social or gregarious group cannot be ruled out. 展开更多
