Aphanurus stossichii (Monticelli, 1891) is redescribed from Boops boops (L.) from various localities in the NE Atlantic region (off Spain), the Mediterranean (off Spain and Turkey) and the Black Sea (off Bulgaria). The material from the Atlantic coast of Spain showed differences in egg-size and shape and a characteristic ornamentation of the anterior third of the hermaphroditic duct. A comparison with samples from B. boops collected off Antalya (Turkey) and off the Bulgarian Black Sea coast revealed a considerable size variation and confirmed the presence of tubercles in the terminal part of the hermaphroditic duct. A. virgula Looss, 1907, previously considered a synonym of A. stossichii, is redescribed on the basis of voucher material from Engraulis encrasicolus ponticus Alexandrov collected off the Bulgarian Black Sea coast and previously identified as A. stossichii. A. virgula can be distinguished from A. stossichii by its smaller size and substantially lower range limits for all metrical features, the more posterior position of the base of sinus-sac, and the eggs being less numerous and larger in relation to the size of the body and gonads.
基于在东北大西洋地区（西班牙沿海）、地中海（西班牙和土耳其沿海）以及黑海（保加利亚沿海）不同地点采集的博氏鲷（Boops boops (L.)）样本，对斯托氏无鳍线虫（Aphanurus stossichii (Monticelli, 1891)）进行了重新描述。来自西班牙大西洋沿岸的样本在卵的大小和形状以及雌雄同体管道前三分之一处具有特征性纹饰方面存在差异。与从土耳其安塔利亚和保加利亚黑海沿岸采集的博氏鲷样本进行比较，发现其大小存在相当大的差异，并证实了雌雄同体管道末端存在瘤状物。1907年的弗氏无鳍线虫（A. virgula Looss），此前被认为是斯托氏无鳍线虫的同义词，现根据从保加利亚黑海沿岸采集的 Pontic 沙丁鱼（Engraulis encrasicolus ponticus Alexandrov）的凭证材料进行重新描述，该样本此前被鉴定为斯托氏无鳍线虫。弗氏无鳍线虫与斯托氏无鳍线虫的区别在于其体型较小，所有测量特征的范围下限显著更低，窦囊基部位置更靠后，且相对于身体和性腺大小而言，卵的数量更少且更大。
