A new species of Conger eel is described from a single specimen (569 mm total length) collected off Kanyakumari, Southwest coast of India, Arabian Sea. The following characters distinguish the new species from other congeners: dorsal-fin origin behind the pectoral-fin tip; head larger, 18.5% TL; longer predorsal length 24.0% TL; relatively shorter trunk, uniserial teeth at the posterior end of vomerine patch; body blackish to dark brown; pectoral fin completely darker; cephalic pores rim whitish; SO pores 3; IO pores 6; pectoral rays 19; total vertebrae 141+. Genetic analysis of the mitochondrial COI gene revealed that the new species is closely related to Conger verreauxi Kaup, 1856 and Conger macrocephalus Kanazawa, 1958, with a genetic divergence of 5.7% and 5.9% respectively.
一种新的海鳗种类是根据在印度西南海岸卡尼亚库马里附近阿拉伯海采集的一个标本（全长569毫米）描述的。以下特征将该新物种与其他同属物种区分开来：背鳍起点在胸鳍尖端之后；头部较大，占全长的18.5%；背鳍前长度较长，占全长的24.0%；躯干相对较短，犁骨齿斑后端为单列齿；身体呈黑色至深褐色；胸鳍完全较暗；头部小孔边缘呈白色；眶下小孔3个；眶上小孔6个；胸鳍条19根；总椎骨141个以上。线粒体COI基因的遗传分析表明，该新物种与1856年考普描述的康吉海鳗（Conger verreauxi）和1958年金泽描述的大头海鳗（Conger macrocephalus）密切相关，遗传差异分别为5.7%和5.9%。
