在Anker等人的论文中，Chelomalpheus Kim，1998和Cavipelta Hayashi，1998被视为Stenalpheops Miya，1997的异名。(2001年)。因此，这些属的模式种(Cheromalpheus koreanus Kim，1998和Cavipelta yamashitai Hayashi，1998)被命名为尖吻海鞘S.anacantus Miya，1997。实际上，这些作者忽略了上述三个种的形态特征存在差异。例如，所有的模式标本都没有尾部的尾部；大的雄性标本有一个形状异常的脊状突起，这与另一个命名种的生长序列的中间阶段相对应，也就是尖吻鱼属。通过研究来自中国海的大量标本的机会确定了文冠鱼的模式标本实际上由两个种组成，并且同样的模式标本也被发现用于山猫尾鱼的模式标本，1998年；此外，朝鲜的Cheromalpheus koreanus Kim，1998被发现是一个有效种，并被转移到Stenalpheopps；和S.crangonus(Anker，Jeng&Chan，2001)在这里与文冠鱼同名，其名称优先，这一有效的种现在在这里重新描述。
The nominal genera Chelomalpheus Kim, 1998 and Cavipelta Hayashi, 1998 were treated as synonyms of Stenalpheops Miya, 1997 in the paper by Anker et al. (2001). Therefore, the type species of those genera (Chelomalpheus koreanus Kim, 1998 and Cavipelta yamashitai Hayashi, 1998, respectively) were synonymized with S. anacanthus Miya, 1997. Actually, those authors ignored that the morphological characters of the three species mentioned above show differences. For instance, all type specimens of Chelomalpheus koreanus Kim, 1998 are without a caudal appendix; the large male specimens of Cavipelta yamashitai Hayashi, 1998 have an abnormal shaped chela, which corresponds with the middle stage in a growth series of another nominal species, i.e., S. anacanthus. The opportunity to study abundant specimens from the China seas established that the type specimens of S. anacanthus Miya, 1997 are in fact composed of two species, and the same was found for the type specimens of Cavipelta yamashitai Hayashi, 1998; in addition, Chelomalpheus koreanus Kim, 1998 was found to be a valid species and is transferred to Stenalpheops; and S. crangonus (Anker, Jeng & Chan, 2001) is herein synonymized with S. anacanthus Miya, 1997, which name has priority, and this valid species is now re-described herein.
