Two new species of dark-body snake eels are described based on specimens collected from Taiwan. has a long tail; dorsal-fin origin above posterior third of pectoral fin; tip of lower jaw anterior to anterior-nostril tube; two simple, pointed protrusions along upper lip; preoperculomandibular pores 6 or 7 + 3; teeth on jaws and vomer mostly uniserial, except for biserial on posterior portion of maxilla and anterior portion of symphysis of dentary; vertebral formula 12-55-153 and median fins with narrow dark margins, except the pale fin origins. has a dorsal-fin origin well behind gill opening; mainly 4 rows of teeth on jaws; no protrusions along upper lip; a smaller head; mean vertebral formula 24-64-163 and pale median fins. Based on some recent papers and our result, a revised key to species is herein provided.
基于从台湾采集的标本，描述了两种新的深色蛇鳗物种。[物种一]尾巴长；背鳍起点在胸鳍后三分之一上方；下颌尖端位于前鼻孔管前方；上唇有两个简单的尖状突起；鳃盖前下颌孔6或7 + 3；颌骨和犁骨上的牙齿大多为单列，除了上颌后部和齿骨联合前部为双列；脊椎公式为12 - 55 - 153，除了浅色的鳍起点外，中鳍有狭窄的深色边缘。[物种二]背鳍起点在鳃孔后方很远；颌骨上主要有4排牙齿；上唇没有突起；头部较小；平均脊椎公式为24 - 64 - 163，中鳍浅色。基于最近的一些论文和我们的结果，本文提供了一个修订后的物种检索表。
