Abstract

A new genus and species of ophichthid eel, Sympenchelys taiwanensis is described. The genus is distinguishable from all other myrophine genera by having neural and haemal spines with well-developed paddle-like tips, and from two closely similar genera, Mureaenichthys Bleeker 1853 and Skythrenchelys Castle & McCosker 1999, by the following combination of characters: an unconstricted gill opening; a minute flap just posterior to the gill opening; a slender cleithrum; three preopercular pores; a slender and distinctly tapered maxilla; an undeveloped supraoccipital crest; and large and recurved teeth on jaws and vomer. Sympenchelys taiwanensis is described from five specimens collected from Taiwan, the northwestern Pacific Ocean.

摘要

描述了一种新的蛇鳗属和物种——台湾合鳃鳗（Sympenchelys taiwanensis）。该属与所有其他蛇鳗属的区别在于其神经棘和血棘具有发育良好的桨状尖端，与两个非常相似的属，即1853年的缪氏蛇鳗属（Mureaenichthys Bleeker）和1999年的斯氏蛇鳗属（Skythrenchelys Castle & McCosker）的区别在于以下特征组合：鳃孔无缢缩；鳃孔后方有一个微小的皮瓣；鳃盖骨细长；有三个前鳃盖孔；上颌细长且明显渐细；上枕嵴不发达；颌骨和犁骨上有大的弯曲牙齿。台湾合鳃鳗是根据从西北太平洋台湾采集的五个标本描述的。
