, a new species of blind loach from the Xijiang River, China (Teleostei, Nemacheilidae).

A new cave-dwelling fish, , is described here based on specimens collected from a karst cave in Guangxi Zhuang Autonomous Region, China, interconnected with the Hongshui River system, a tributary of the Xijiang River in the Pearl River (Zhu Jiang) Drainage. The species can be distinguished from its congeners by a combination of morphological characters. A key to the cave-dwelling species of in the Xijiang River is provided.

A new blind loach species, Triplophysa huanjiangensis (Teleostei: Balitoridae), from Guangxi, China.

A new blind loach of the genus Triplophysa was collected in 2007 from a cave in Leyi village, located near Chuanshan Town, Huangjiang County in the Guangxi Zhuang Autonomous Region of southern China. The new species, Triplophysa huangjiangensis sp. nov, can be distinguished from its congeners by eyes and scales absent; caudal-fin forked; adipose keel present; lips with furrows; distal margin of dorsal-fin truncate, dorsal fin origin much closer to caudal-fin base than snout tip; 8-9 branched dorsal-fin rays; 6-7 branched pelvic-fin rays; 6 branched anal-fin rays; 10-11 branched pectoral-fin rays; 13-14 branched caudal-fin rays; pectoral-fin length 52.

[Morphologic differentiation analysis for rounded caudal fin group of Oreonectes (Balitoridae) from China].

Morphological characteristics were compared between three recorded species of rounded caudal fin Oreonectes and specimens collected from Guan'an of Guangxi. The results showed the Oreonectes sp. from Guan'an was distinguished from O.

[Description of a new species of Barbinae, Sinocyclocheilus huangtianensis from China (Teleostei: Cypinidae)].

A new species, Sinocyclocheilus huangtianensis, is found from a cave of Hejiang River, Hezhou, Guangxi, China. This river is a tributary of the Pearl River. It is similar to S.

[A fish-based biotic integrity index selection for rivers in Hechi Prefecture, Guangxi and their environmental quality assessment].

This study aims to develop a multi-metric, fish-based Index of Biological Integrity (IBI) for assessing the environmental quality of rivers in Hechi Prefecture, Guangxi Province, South China. Data on fish assemblage were collected via electrofishing We screened 21 candidate metrics representing attributes of fish assemblage. Among these, six metrics were finally selected for the IBI.
