中国鲃亚科金线鲃属鱼类一新种——黄田金线鲃 (鲤形目:鲤科)

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

  • 摘要: 该文记述了采自广西贺州市贺江水系—— 洞穴的鲤科鲃亚科金线鲃属鱼类一新种, 命名为黄田金线鲃(Sinocyclocheilus huangtianensis Zhu, Zhu et Lan sp. nov.)。新种眼睛正常, 背鳍末根不分枝鳍条柔软, 后缘无锯齿, 与属内同分布在贺江水系的已知种季氏金线鲃及邻近漓江水系的桂林金线鲃相似, 但新种侧线鳞为52~59枚, 侧线上鳞17~23, 侧线下鳞16~17, 围尾柄鳞40~46, 鳃耙9~10, 眼径为体长的4.3%~5.4%, 眼间距为体长的9.2%~9.6%, 口宽为体长的6.0%~7.3%, 与季氏金线鲃和桂林金线鲃有明显区别。

     

    Abstract: 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. jii, distributed in Hejiang and S. guilinensis distributed in Lijiang by having a soft dorsal spine without serration and normal eyes. The combination of the following characteristics makes this new species different to S. jii and S. guilinensis: (1) the lateral line scales 52–59, up lateral line scales 17–23, the down lateral line cales 16–17, the circumpeduncular scales 40–46; (2) gill raker 9–10; (3) eye diameter/SL 4.3–5.4%; (4) interorbital width/SL 9.2–9.6%; and (5) mouth width/SL 6.0–7.3%.
