Complete mitochondrial genome of and its phylogenetic status within the family Cobitidae (Cypriniformes).

In this study, the complete mitochondrial genome of was first determined by the primer walking sequence method. The complete mitochondrial genome was 16,574 bp in length, including 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a control region (D-loop). The gene arrangement pattern was identical to that of other teleosts.

, a new species of spiny eel (Pisces, Mastacembelidae) from the Zhu-Jiang Basin, with a note on the type locality of (Bleeker, 1870).

Background: The spiny eel genus belongs to the family Mastacembelidae of the order Synbranchiformes. Kottelat and Lim (1994) utilised as the type species to propose the genus. Currently, it contains a single species widespread in eastern and southern China and northern Vietnam.

A new species of genus (Bacillariophyta) from Tibet, China.

During the investigation of the freshwater diatoms from Tibet, a monoraphid species was observed from a hot spring near Anduo County, located on a plateau in the central portion of Tibet. This species shares the diagnostic features of , such as the valve bent along the transapical axis, striae uniseriate to biseriate from centre to the apices and areolae with special structures located at the end of each stria. We compared the morphological characters of this new species with the others in this genus and show it to be new; it is named This species has small valves with slightly protracted ends with nearly capitate apices, lanceolate axial area, central area unilaterally expanded to the margin, striae uniseriate to biseriate, but, in some valves, the striae are only uniseriate.

Diversity and distribution of fish in the Qilian Mountain Basin.

The Qilian Mountain Basin, on the north-eastern edge of the Qinghai-Tibet Plateau (QTP), supports a high diversity of native and endemic fish. However, the detailed species inventory and distribution patterns concerning fish in the whole Basin remain unknown, which hinders the conservation of biodiversity and assessment of ecological health. We compiled a comprehensive species richness and distribution database of freshwater fish in the Qilian Mountain Basin, based on field investigations and exhaustive data collection from 50 rivers or lakes.

Updated species checklist of fishes from Lake Dongting in Hunan Province, South China: Species diversity and conservation.

A lack of an updated checklist of freshwater fish species from Lake Dongting is a great hindrance to further biodiversity analysis. A seasonal survey of fishes in the lake was conducted from October 2017 to January 2019. Based on the data obtained during the field survey and coupled with known literature and the latest taxonomic development of relevant taxa, the species checklist of fishes from Lake Dongting was updated.

A new freshwater species (Bacillariophyta, Achnanthidiaceae) from Sichuan Province, China.

A new freshwater diatom species, Yu, You & Wang, from Sichuan Province, China, is described. The morphology of this species was analyzed with scanning electron microscopy (SEM) and light microscopy (LM). belongs to the -like subgroup, which has external distal raphe ends curved in opposite directions of the valve.

Taxonomic study of a novel terrestrial alga, sp. nov. (Protosiphonaceae, Chlorophyta), from the Qinghai-Tibet Plateau.

There is only one species of in the literature currently. It was found in gray soil in Russia for the first time. According to molecular data analysis results, the isolated algal strain is most closely related to .

Two new freshwater species of the genus (Bacillariophyta, Achnanthidiaceae) from Qingxi River, China.

We describe two new species, and , from Qingxi River, Anhui Province, China, based on light and scanning electron microscopy. Both species belong to the " complex" of the genus, based on their possession of transapically-elongated areolae and deflected external distal raphe fissures. has a slightly irregular linear-lanceolate valve with rounded or weakly protracted apices and a transapically rectangular or bow tie central area on the raphe valve.

, a new species of loach (Teleostei: Gastromyzontidae) from the middle Chang-Jiang Basin in Guizhou Province, south China.

Background: The gastromyzontid genus was established by Hora in 1932, based on the type species . The genus is a loach group adapted to running waters of streams from southern China, northern Vietnam and Laos. Currently, 19 valid species of the genus have been recognised.

Re-description of the loach species (Teleostei, Botiidae), with the description of from southern Zhejiang Province, China.

(Nichols, 1925), a loach species, originally described from Dongting Lake, was recently rehabilitated, based on the examination of the holotype and non-topotypical specimens. Several field surveys conducted from 2016 to 2019 in Zhejiang, Jiangxi and Hunan Provinces, P.R.

Description of sp. nov. (Annelida, Clitellata, Enchytraeidae) from central China, with comments on species records of from China.

is described from hardwood forest soil in Wuhan, China. This moderately sized enchytraeid species of 6-9 mm body length is characterized by: (1) an oesophageal appendage with tertiary branches, (2) three pairs of secondary pharyngeal gland lobes in V, VI, VII, (3) five pairs preclitellar nephridia, from 5/6 to 9/10, (4) dorsal vessel originating in clitellar segments, (5) a girdle-shaped clitellum, (6) a relatively small male reproductive apparatus without seminal vesicle, and (7) spermathecae that extend to VI-VII. DNA barcodes of paratype specimens of the new species are provided.

Characterization of the complete mitochondrial genome of Yu & Wu, 1989 (Acanthocephala, Illiosentidae).

The mitogenome of is 13,864 bp in length and has the circular structure typical of metazoans. It contains 36 genes: 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs) and 12 protein-encoding genes (PCGs). All genes are transcribed from the same strand.

Characterization of the complete mitochondrial genome of Xi et al., 2018 (Cestoda, Caryophyllidea).

is a recently described caryophyllidean monozoic tapeworm from schizothoracine fish on the Tibetan Plateau. In the present study, the complete mitochondrial genome of is determined for the first time. The mitogenome is 15,034 bp in length with an A+T content of 59.

Phylogenomic analysis of Balantidium ctenopharyngodoni (Ciliophora, Litostomatea) based on single-cell transcriptome sequencing.

In this paper, we present transcriptome data for Balantidium ctenopharyngodoni Chen, 1955 collected from the hindgut of grass carp (Ctenopharyngodon idella). We evaluated sequence quality and de novo assembled a preliminary transcriptome, including 43.3 megabits and 119,141 transcripts.
