中国洞穴盲鳅一新种——红盲高原鳅Triplophysa erythraea sp.nov.(鲤形目:条鳅科)

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

  • 摘要: 基于形态特征比较和线粒体cyt b基因序列分析,该文记述了分布于湖南省花垣县大龙洞的典型洞穴鱼类一新种——红盲高原鳅 (Triplophysa erythraea sp. nov.)。该种有如下特征区别于同属的其他物种:眼晴完全退化;缺乏鳞片和色素,但因体表透明而使身体呈现血液的颜色(血红色);尾鳍17;口角须最长;鳍透明,胸鳍后伸至胸鳍至腹鳍起点的2/3处;背鳍和腹鳍起点相对;鳔后室发达,膨大呈游离膜质状。

     

    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.
