A new cave-dwelling blind loach, Triplophysa erythraea sp. nov. (Cypriniformes: Nemacheilidae), from Hunan Province, China.

ABSTRACT: A new blind loach species, Triplophysa erythraea sp. nov., from a karst cave in Hunan Province, central south China, is described based on morphology and cyt b gene sequencing. It can be distinguished from other species of Triplophysa by the following combination of characters: eyes absent; body scaleless and colorless; caudal-fin 17; maxillary barbel longest; fins transparent, compressed pectoral-fin reaching 2/3 distance between pectoral-fin and pelvic-fin origins; pelvic-fin and dorsal-fin origins relative; posterior chamber of airbladder well developed, long, oval, and dissociative.

The complete mitochondrial genome of a cave-dwelling loach Triplophysa baotianensis (Teleostei: Nemacheilidae).

Project description:Triplophysa baotianensis belong to the genus Triplophysa (Teleostei, Nemacheilidae), endemic to Guizhou Province, Southwestern China. In this study, the complete mitochondrial genome of T. baotianensis was sequenced and reported for the first time. The circular mitogenome was 16,576 bp in length and consisted of 13 protein-coding genes, 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and 1 non-coding control region. The overall base composition was 30.79% A, 27.62% T, 25.46% C, and 16.13% G with 41.59% GC content. Phylogenetic analysis using mitochondrial genomes of 40 species showed that all Triplophysa species clustered as one monophyletic clade, and T. baotianensis was the closest to (T. nasobarbatula + (T. rosa + T. xiangxiensis)).

Triplophysa wulongensis, a new species of cave-dwelling loach (Teleostei, Nemacheilidae) from Chongqing, Southwest China.

Project description:We describe a new species of cave-dwelling loach, Triplophysa wulongensis sp. nov., based on specimens collected in a subterranean pool in a cave in Wulong County, Chongqing, Southwest China. The pool is connected to the Wujiang River drainage. Triplophysa wulongensis differs from its congeners by the following combination of characters: eyes present, caudal fin with 18 branched rays; posterior chamber of the air bladder degenerate; stomach U-shaped; intestine without bends or loops immediately posterior to stomach; body smooth and scaleless, and lateral line complete. The mitochondrial cytochrome b sequence differs from those of other published sequences of species of Triplophysa by 14.9-24.9% in K2P distance. Phylogenetic analysis based on cytochrome b gene sequences recovered T. wulongensis as sister taxon to all other cave-dwelling species of Triplophysa.

The complete mitochondrial genome of Triplophysa erythraea (Huang et al. 2019) (Cypriniformes, Nemacheilidae).

Project description:In this study, the complete mitochondrial genome of Triplophysa erythraea was determined for the first time. Results showed the mitogenome was 16 565 bp, including 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes and 2 non-coding regions. The overall base composition of its mitochondrial genome was 28.9% A, 25.2% T, 28.7% C and 17.2% G. Phylogenetic tree revealed that Triplophysa erythraea had the closest relationship with Triplophysa xiangxiensis, which was also found in Xiangxi Tujia and Miao Nationality Autonomous Prefecture, Hunan province. In general, this study provided valuable information for conservation genetics analyses of Triplophysa erythraea and further displayed the evolution of species within the genus Triplophysa.

A new species of Triplophysa (Cypriniformes, Nemacheilidae) from Weihe River in Gansu Province, China.

Project description:A new species of Tibetan loach, Triplophysa weiheensis sp. nov., is described from the Weihe River in Gansu Province, China, based on morphological and molecular analyses. The new species can be distinguished from all known congeners by a unique combination of the following characters: scaleless; snout abruptly sloping downward, anterior to anterior nostril; lower jaw crescentic, not sharp; body without obvious mottling; lateral line interrupted on posterior trunk at pelvic-fin distal extremity; caudal-peduncle length 2.0-2.7 times its depth; branched rays of pectoral fin 10-11; branched rays of pelvic fin 5-6; inner gill rakers on 1 st gill arch 14-16; vertebrae 4+34-36; intestine with 6-7 loops, length ca. 1.8 times SL ( n=3); bony capsule of air bladder small and thin; posterior chamber of air bladder absent.

Homatula guanheensis sp. nov. (Teleostei: Nemacheilidae), a new species of loach from Henan Province, China.

Project description:BackgroundThe genus Homatula belongs to the order Cypriniformes and family Nemacheilidae. Nichols (1925) set up the genus as a subgenus of Barbatula by the type species of Nemacheilus potanini. Currently, it is recognised as a valid genus. Nineteen valid species have been already reported in the drainage of the Yellow, Yangtze, Pearl, Lancang, Red and Nujiang Rivers. H. variegata, H. longidorsalis, H. berezowskii and H. potanini are distributed in the Yangtze River drainage in China. H. laxiclathra is mainly distributed in the Weihe River, a tributary of the Yellow River. The remaining species are mainly distributed in the rivers of Yunnan Province.New informationHomatula guanheensis sp. nov., a new species, is described from the Guanhe River of the HanJiang River drainage (a tributary of the Yangtze River), Xixia County, Henan Province, China. It can be distinguished from its congeners by a combination of the following characters: the vertical brown bars on the body are wider than their interspaces, numbering 19-22; predorsal body partially scaled; the lateral line complete; adipose crest on caudal peduncle not reaching forward; the position of the anal-fin origin and the intestinal form. The new species displays distinct molecular divergence in the Cytochrome oxidase I (COI) and Cytochrome b (Cyt b) genes.

The complete mitochondrial genome of Triplophysa nanpanjiangensis Zhu and Cao 1988 (Cypriniformes: Nemacheilidae).

Project description:The genus Triplophysa is an ideal taxon for understanding geological evolution. In this study, for the first time, we report the complete mitochondrial genome of T. nanpanjiangensis Zhu and Cao 1988 using the Nanopore sequencing. It is a circular genome with a length of 16558 bp, comprising 22 tRNAs, 13 protein-coding genes (PCGs), two rRNAs, and one non-coding control region. The phylogenetic tree demonstrates that T. nanpanjiangensis is sister to Triplophysa zhenfengensis and placed within the genus Triplophysa. Our mitogenomic studies provide a new pathway for understanding the molecular phylogeny of the genus Triplophysa.

Four new hypogean species of the genus Triplophysa (Osteichthyes, Cypriniformes, Nemacheilidae) from Guizhou Province, Southwest China, based on molecular and morphological data.

Project description:Recently described cave species of the genus Triplophysa have been discovered in southwestern China, suggesting that the diversity of the genus is severely underestimated and that there may be many undescribed species. In this work, four new species of the genus Triplophysa are described from southwestern Guizhou Province, China, namely Triplophysacehengensis Luo, Mao, Zhao, Xiao & Zhou, sp. nov. and Triplophysarongduensis Mao, Zhao, Yu, Xiao & Zhou, sp. nov. from Rongdu Town, Ceheng County, Guizhou, Triplophysapanzhouensis Yu, Luo, Lan, Xiao & Zhou, sp. nov. from Hongguo Town, Panzhou City, Guizhou, and Triplophysaanlongensis Song, Luo, Lan, Zhao, Xiao & Zhou, sp. nov. from Xinglong Town, Anlong County, Guizhou. These four new species can be distinguished from all recognized congeners by a combination of morphological characteristics and significant genetic divergences. The discovery of these species increases the number of known cave species within the genus Triplophysa to 39, making the genus the second most diverse group of cave fishes in China after the golden-line fish genus Sinocyclocheilus. Based on the non-monophyletic relationships of the different watershed systems in the phylogenetic tree, this study also discusses the use of cave species of the genus Triplophysa to determine the possible historical connectivity of river systems.
