| 中文摘要 | 该文记述了采集自云南省文山州西畴县兴街镇干海子(红河水系)一洞穴的鲤科鲃亚科金线鲃属鱼类一新种,命名为西畴金线鲃(Sinocyclocheilus xichouensis Pan,Li,Yang et Chen sp.nov.)。该新种眼睛正常,背鳍末根不分枝,鳍条变粗变硬,后缘3/5具锯齿,与属内分布在邻近南盘江水系的已知种大眼金线鲃(S.macrophthalmus)、圭山金线鲃(S.guishanensis)、狭孔金线鲃(S.angustiporus)、侧条金线鲃(S.lateristritus)、丘北金线鲃(S.qiubeiensis)、滇池金线鲃(S.grahami)、曲靖金线鲃(S.qujingensis)、麻花金线鲃(S.maculatus)、紫色金线鲃(S.purpureus)及疑似红河水系易门金线鲃(S.yimenensis)相似。籍第一鳃弓外侧鳃耙9以下的特征,可与大眼金线鲃相区别;眼间距为体长的8.1%～9.9%,吻须后伸超过眼后缘,口角须后伸超过前鳃盖骨后缘,可与圭山金线鲃相区别;背鳍起点与腹鳍起点相对,体侧沿侧线无黑色横带,可与侧条金线鲃相区别;侧线鳞74～88,侧线上鳞20,侧线下鳞16,可与滇池金线鲃相区别;侧线弯曲,侧线鳞74～88,围尾柄鳞48,可与曲靖金线鲃相区别;背鳍前距为体长的47.1%～53.7%,背鳍基长为体长的12.8%～15.8%,臀鳍前距为体长的66.0%～71.0%,臀鳍长为体长的13.7%～17.1%,胸鳍前距为体长的26.0%～29.5%,尾柄长为体长的19.3%～24.7%,下颌长为体长的4.7%～7.0%,明显区别于易门金线鲃;全身被鳞,具侧线鳞,可与其分布邻近的麻花金线鲃和紫色金线鲃相区别;背鳍前鳞35～39,鳃耙6,眼间距为体长的8.1%～9.9%,可与狭孔金线鲃及丘北金线鲃相区别。 |
| 英文摘要 | In the present study, a new species of the genus Sinocyclocheilus Fang 1936, Sinocyclocheilus xichouensis, was described from the Ganhaizi tributary of Chouyang River, Red River drainage, located in southeast Yunnan, China. This species has normal eyes and a strong dorsal spine with serrations on the lower 3/5 part. In general, this species is similar in morphology to S. macrophthalmus, S. guishanensis, S. angustiporus, S. lateristritus, S. qiubeiensis, S. grahami, S. qujingensis, S. maculatus and S. purpureus distributed in the Nanpanjiang River, and S. qiubeiensis distributed in the Red River. It is distinguished from S. macrophthalmus by possessing fewer than 9 gill rakers. However, S. xichouensis can be distinguished from S. guishanensis by its interorbital width/SL of 8.1~9.9%, rostral barbels extended to posterior margin of eye and maxillary barbels extended to posterior preopercular. It is distinct from S. lateristritus by dorsal-fin origin opposite of pelvic fin origin, with no a black stripe along the lateral line. It is distinguished from S. grahami by 74~88 lateral-line scales, 20 scale rows above the lateral line, and 16 scale rows below the lateral line. It is distinguished from S. qujingensis by a curved lateral line, 74-88 lateral-line scales, 48 circumpeduncular scales. It can be distinguished from S. yimenensis by the ratio of predorsal length, dorsal-fin base length, preanal length, anal fin length, prepectoral length, caudal-peduncle length and lower jaw length to SL, 47.1%-53.7%, 12.8%-15.8%, 66.0%-71.0%, 13.7%-17.1%, 26.0%-29.5%, 19.3%-24.7%, 4.7%-7.0%, respectively. It is distinguished from S. maculatus and S. purpureus by possession of lateral line and scaled body and distinguished from S. angustiporus and S. qiubeiensis by 35~39 predorsal scales, 6 gill rakers, and interorbital width/SL of 8.1%-9.9%. |
