Cirrhilabrus apterygia.是一条鱼类多年来的鱼类的新名称，但它是如此奇怪的是，其中一个常见的名字是突变名称。首先描述为Conniella Apterygia.1983年，澳大利亚西北罗德利浅滩的这种特殊濑鱼几乎与帕劳的仙女濑鱼相同，整体外观保存一个离散但深刻的差异。
出于未知这种罕见的糖果条纹仙女濑鱼已经失去了盆腔鳍，所有相关的整数都是如此剧烈的物理差异Conniella.为原始物种描述竖立了属。这是一个非常合理的事情，因为骨盆鳍片的存在是许多鱼群的定义特征，但进一步检查突变的濑鱼和它的孤独的属于它Cirrhilabrus.仙女伴侣属。
There are no good explanations as to why the mutant wrasse lost its pelvic fins, but since many wrasses propel themselves mostly with their pectoral fins, perhaps this trait first appeared as a congenital defect which wasn’t detrimental to their survival and became passed down through the small population of this limited range species. The new generic placement ofCirrhilabrus apterygia.不是一个新的物种，而是一个新组合这带来了描述的童话总数Cirrhilabrus.与64属，有一个值得进一步调查的少数更多。[Zootaxa.]
