对来自台湾和日本的 Ilyophine 鳗鱼新种 Dysommina orientalis 进行了描述和说明。该物种长期以来被认为是西太平洋的 Dysommina rugosa，与 D. rugosa 的区别在于背前椎骨数量较少，总椎骨数量较多，头部长度较短，眼睛较小，犁骨齿列减少，下颌和上颌牙齿数量增加，以及 COI 和 16S 的 DNA 序列存在显着差异。
Dysommina orientalis, a new species of Ilyophine eel from off Taiwan and Japan is described and illustrated. The species had long been recognized as Dysommina rugosa in the western Pacific and is distinguished from D. rugosa by a lower number of predorsal vertebrae, a higher number of total vertebrae, shorter head length, smaller eye size, reduced vomerine dentition, and an increased number of both mandibular and maxillary teeth, as well as significant differences in DNA sequence in COI and 16S.
