【摘要】 <正> 皮鳞鱼属(Rugogymnocypris)系岳佐和、黄宏金于1964年以采自西藏羊卓雍湖的皮鳞鱼Rugogymnocypris tibetanus为模式而建立的。所依据的主要特征是“全身被着排列不整齐、分布不均匀、较大、埋于皮下的鳞片”,并以其极相似于裸鲤属(Gymnocypris)而定的属名。 1962、1963和1965年我们在青海湖渔场先后收集到四尾具有类似皮鳞鱼鳞片的青海湖裸鲤标本(图1);1974年,在西藏班公湖采到一尾类似的高原裸裂尻鱼标本(图2)。访问当地渔工和群众,一致认为“皮鳞鱼”标本是极为罕见的。不由使人怀疑,“皮鳞鱼”所更多还原

【Abstract】 The genus Rugogymnocypris and the species R.tibetanus are described by Yueh and Hwang (1964),based upon two specimens "covered with large,scattered and embedded scales" collected from Yarzhoyum-Co.After a detailed study,we found that this species agrees in all the other characters with Gymnocypris waddellii Regan found in the same water-body (table 1).Furthermore,five specimens with such pattern of squamations were collected during the years 1962-1974 from Qinghai-Hu (four specimens) and Bangong-Co (one specimen) by the authors.They agree with the species found in the respective water-bodies,i.e.Oymnocypris p.przewalskii (Kessler) and Schizopygopsis stoliczkae.Steind.in all characters (table 1).Those rare specimens covered with irregular and sparse scales as stated above present,in our opinion,a phenomenon of reversion and an evidence that the progenitors of Gymnocypris and Schizopygopsis were the scaled members of the Schizothoracinae.We,therefore,consider that Rugogymnocypris tibetanus Yueh et Hwang is a synonym of Gymnocypris waddellii Regan,while the genus Rugogymno-cypris should be abandoned.更多还原
