| 2008年5月及2010年8月在广东省增城市及河源市采得一批鱼类标本，其中20尾经鉴定为珠江水系鱼类新纪录——带刺光唇鱼（Acrossocheilus spinifer Yuan，Wu & Zhang，2006）。该种主要鉴别特征包括：（1）体侧具有5 ~ 6条垂直的黑色条纹，每条约占2列鳞片宽，向下延伸至侧线以下2行鳞片，呈对称或不对称分布；（2）第2条垂直条纹位于背鳍末根不分枝鳍条的下方；（3）背鳍末根不分枝鳍条为粗壮的硬刺，后缘具细小的锯齿；（4）背鳍鳍间膜外缘2/3黑色。标本现保存于华南师范大学生命科学学院鱼类标本室。 |
| 英文摘要: |
| Among the collection from the Dongjiang River, one tributary of the Pearl River in Zengcheng city and Heyuan city, Guangdong province，20 specimens of Acrossocheilus spinifer were identified as a new distribution record in the Pearl River. It could be distinguished by a combination of morphological characters: (1) 5-6 dark vertical bars on the flanks, with each bar 2 scales in width and all bars extending vertically to second scale row below lateral line, and the bars are symmetric or asymmetric; (2) the second bar positioned under the base of last simple dorsal-fin ray; (3) the last simple dorsal-fin ray strong , with small serration along posterior edge; (4) outer 2/3 part of membranes between dorsal fin rays dark. A. spinifer is diagnosed from A. beijiangensis in having 5-6 symmetric or asymmetric vertical dark bars on dorsum and flanks, each bar 1-2 scales in width (vs. in A. beijiangensis 5 symmetric vertical dark bars on flanks and each being 2-4 scales in width).The specimens were deposited in fish specimen room, School of life science, South China Normal University. |
