摘　　要：A new species of the genus Protocobitis, was discovered in an underground water source （110m depth） located about 5km away from the county town of Wuming, Guangxi, China, in May 2006. The new species, Protocobitis polylepis sp. nov., is distinguished from the single congener by the following characteristics：1） light black pigmentation present vs. no pigmentation; 2） entire body covered with scales except for its head and abdomen vs. rudimentary scales present only along the midline of the body; 3） head length 24.1%-24.8% of SL vs. 19.8%-22.1% of SL; 4） body depth 16.2%-16.3% of SL vs. 11.5%-13.0% of SL; 5） Inner rostral barbel length 19.8%-21.0% of head length vs. 9.4%-11.8% of head length; outer rostral barbel length 28.6%-30.2 % of head length vs. 15.3%-21.8% of head length; maxillary barbell length 44.6%-46.0% of head length vs. 22.4%-31.8% of head length.2006年5月从广西武鸣县城5km的地下龙潭中发现了原花鳅属的一个新种。该新种被命名为多鳞原花鳅(Protocobitis polylepis),与该属唯一已知种无眼原花鳅(Protocobitis typhlops)的鉴别特征如下:1)体背和体侧具淡的色素vs.色素完全退化;2)除头和腹部外身体其余部分被稀疏鳞片vs.稀疏鳞片仅见于体侧中线;头长为体长24.1%-24.8%vs.19.8%-22.1%;体高为体长16.2%-16.3%vs.11.5%-13.0%;内侧吻须长为头长19.8%-21.0%vs.9.4%-11.8%;外侧吻须长为头长28.6%-30.2%vs.15.3%-21.8%;颌须长为头长44.6%-46.0%vs.22.4%-31.8%。
