A new-record species of genus Saurogobio in Henan Province-Saurogobio gymnocheilus

摘要：

自2012年至2021年,河南省鱼类资源调查队对省内鱼类资源进行了全面系统调查.在整理标本期间,发现在黄河与淮河采集的多尾蛇鮈属鱼类与此前河南已有记录的蛇鮈(Saurogobio dabryi)和长蛇鮈(Saurogobio dumerili)形态明显不同.运用形态学和分子系统学的方法对其进行分类鉴定,发现其唇薄简单,不发达,上下唇均无明显乳突,其他可量和可数性状也完全符合光唇蛇鮈(Saurogobio gymnocheilus)的鉴别特征.此外,基于Cyt b序列的分子系统学分析也显示其与长江流域的光唇蛇鮈具有最近亲缘关系,遗传距离仅为0.9%,应为同种,支持形态学鉴定结果.基于此,确定本次采集到的蛇鮈属鱼类为光唇蛇鮈,是河南省新纪录种,同时也是其在黄河流域和淮河流域分布的首次记录(此前记录仅在长江中上游分布).

From2012 to 2021,the fish resources survey team of Henan Province conducted a comprehensive and systematic survey of fish resources in our province.During the preparation of the specimens,it was found that the some specimens of genus Saurogobio collected in the Yellow River and Huaihe River were significantly different in morphology from Saurogobio dabryi and Saurogobio dumerili previously recorded in Henan,and should be different species.In this study,the morphological and molecular systematic methods were used to identify them.It was found that the lip of Saurogobio species need to be identified in Henan Province was thin,simple and underdeveloped,and there were no obvious papillae on the upper and lower lips.Other measurable and countable characters were also completely consistent with the Saurogobio gymnocheilus.In addition,the molecular phylogenetic analysis based on the Cyt b gene also showed the closest relationship between the specimen and Saurogobio gymnocheilus in the Yangtze River,with a genetic distance of only 0.9%,which supports the morphological identification result.Therefore,it is determined that the specimen is Saurogobio gymnocheilus,which is a new-record species in Henan Province and the first record of its distribution in the Yellow River and Huaihe River(the previous record was only distributed in the middle and upper reaches of the Yangtze River).
