Swertia hongquanii, a new species of Gentianaceae from Mt. Wuling, southern China.

ABSTRACT: Swertia hongquanii Jia X. Li, a new species of Gentianaceae, is described and illustrated from Mt. Wuling, southern China. It grows on the tops of steep limestone mountains surrounded by cliffs above an altitude of ca. 1400 m. This species resembles Swertia bimaculata, but differs from the latter by the stem leaf blades 2.0-4.5 × 1.0-2.5 cm, ovate to ovate-cordate, base cordate and subamplexicaul, the seeds irregularly polyhedral and the seed coats minutely thorny and reticulate. Based on morphological traits, i.e. the inflorescence structure and the number and structure of the nectaries, the new species may be a member of series Maculatae. A key to the species of series of section MaculataeOphelia is provided.

Complete chloroplast genome sequence of Swertia mileensis (Gentianaceae): a medicinal species endemic to China.

Project description:Swertia mileensis is an important medicinal plant endemic to South-east Yunnan, China, which has been widely used to treat icteric hepatitis. The complete chloroplast genome sequence of S. mileensis is presented in this study, the total size is 153,015 bp in length with a typical quadripartite structure including a pair of inverted repeat (IRs, 25,786 bp) regions separated by a large single copy (LSC, 83,048 bp) region and a small single copy (SSC, 18,395 bp) region. The overall GC content of it is 38.2%. The cp genome has 134 annotated genes, including 85 protein-coding genes, 37 tRNA genes and 8 rRNA genes. Among these genes, nine genes have one intron and two genes contain two introns. The phylogenetic tree based on 16 complete plastomes of support close relationships among two species of Swertia with 100% bootstrap value.

Gentianamopanshanensis (Gentianaceae), a new species from Yunnan, southwest China.

Project description:Gentianamopanshanensis, a new species of the family Gentianaceae is here described and illustrated. This species is presently known only from the Mopanshan Mountain, Yunnan Province, southwest China. Phylogenetic analysis based on ITS sequence data has shown that this new species is a member of the series Fimbriatae of the section Chondrophyllae. Morphologically, it mostly resembles G.mairei and G.panthaica, but differs clearly from the latter two species in the shape and size of the leaves, and the characters of the corolla throat and plicae.

Description of a new species of Music frogs (Anura, Ranidae, Nidirana) from Mt Dayao, southern China.

Project description:A new species of Music frogs, Nidiranayaoica sp. nov. is described based on a series of adult male specimens collected from Mt Dayao, Guangxi, southern China, providing valuable new information on the phylogeny, bioacoustics, and biogeography of related species within the genus Nidirana. The new species forms the sister taxon to N.daunchina from western China and together the sister taxon to N.chapaensis from northern Vietnam. Nidiranayaoica sp. nov. can be distinguished from all known congeners by a significant genetic divergence in the mitochondrial 16S and CO1 genes, the advertisement call containing 1-3 rapidly repeated regular notes, and the combination of morphological characteristics including a medium-sized body with SVL 40.4-45.9 mm in adult males; lateroventral grooves on every digit, not meeting at the tip of disk; tibio-tarsal articulation reaching the nostril; the presence of a pair of subgular vocal sacs in males; and one single developed nuptial pad on dorsal surface of first finger in males.

Comparative and phylogenetic analyses of Swertia L. (Gentianaceae) medicinal plants (from Qinghai, China) based on complete chloroplast genomes.

Project description:Swertia L. is a large genus in Swertiinae (Gentianaceae). In China, many Swertia species are used as traditional Tibetan medicines, known as "Zangyinchen" or "Dida". However, the phylogenetic relationships among Swertia medicinal plants and their wild relatives have remained unclear. In this study, we sequenced and assembled 16 complete chloroplast (cp) genomes of 10 Swertia species, mainly distributed in Qinghai Province, China. The results showed that these species have typical structures and characteristics of plant cp genomes. The sizes of Swertia cp genomes are ranging from 149,488 bp to 154,097 bp. Most Swertia cp genomes presented 134 genes, including 85 protein coding genes, eight rRNA genes, 37 tRNA genes, and four pseudogenes. Furthermore, the GC contents and boundaries of cp genomes are similar among Swertia species. The phylogenetic analyses indicated that Swertia is a complex polyphyletic group. In addition, positive selection was found in psaI and petL genes, indicating the possible adaptation of Qinghai Swertia species to the light environment of the Qinghai-Tibet plateau. These new cp genome data could be further investigated to develop DNA barcodes for Swertia medicinal plants and for additional systematic studies of Swertia and Swertiinae species.

The complete chloroplast genome sequence of Swertia diluta (Gentianaceae).

Project description:Swertia diluta, a traditional Chinese medicine, is widely used to treat jaundice hepatitis, dysentery, dyspepsia, etc. The plastome is 153,691 bp in length, with one large single copy region of 83,860 bp, one small single copy region of 18,301 bp, and two inverted repeat (IR) regions of 25,765 bp. It contains 134 genes, including 84 protein-coding genes, 8 ribosomal RNA, and 37 transfer RNA. Phylogenetic tree shows that S. diluta is a sister species to S. mussotii. The complete chloroplast genome could provide genetic information of this species would contribute to the formulation of protection strategy.

Two new genera and three new species of cavernicolous trechines from the western Wuling Mountains, China (Coleoptera, Carabidae, Trechinae).

Project description:Two new genera and three new species of cave-adapted ground beetles belonging to the tribe Trechini are established and described: Wulongiusqilinger gen. nov. and sp. nov. from limestone cave Qiankou Dong (Chongqing: Wulong), Qianotrechuscongcongae sp. nov. from cave Shigao Dong (Chongqing: Nanchuan), and Qianlongiuszhoui gen. nov. and sp. nov. from cave Qianlong Dong (Guizhou: Songtao). Wulongiusqilinger sp. nov. is a small aphaenopsian beetle with a thin and elongated body, while Qianlongiuszhoui sp. nov. is a semi-aphaenopsian with a stout body. Both new genera are not closely related to any genus of Trechini occurring in the South China Karst, and so their systematic positions remain unclear.
