Three new species of false moray eels belonging to the genus Chlopsis, family Chlopsidae, are described and illustrated. Chlopsis sagmacollaris, from Western Australia, is characterized by its distinct color pattern with a unique dark saddle on the nape and paler body pigmentation than all other congeners. Chlopsis nanhaiensis, from Taiwan, has a bicolored body with its dorsal-fin origin behind a vertical through posterior margin of gill opening. These characters are shared with C. apterus, C. bicolor, C. bidentatus and C. orientalis sp. nov., but C. nanhaiensis has fewer total vertebrae than other bicolored species (ca. 120 in C. nanhaiensis vs. 125-140 in other four species). Chlopsis orientalis, from Vietnam, is distinguished from all other congeners except C. bicolor by its simple bicolored body, head length (ca. 10% of total length), position of dorsal-fin origin (distinctly behind a vertical through posterior margin of gill opening), and counts of preanal and total vertebrae (35 and 135). Although C. orientalis resembles C. bicolor in meristics and morphometrics, it differs in its pigmentation and possession of stouter intermuscular bones. These new species represent the first records of the genus Chlopsis from the northwestern Pacific Ocean and the eastern Indian Ocean.
描述并图示了裸胸鳝科裸胸鳝属的三种新的拟海鳝。来自西澳大利亚的细纹裸胸鳝的特征在于其独特的颜色模式，颈部有独特的深色鞍状斑，且身体色素沉着比所有其他同属物种更浅。来自台湾的南海裸胸鳝身体分为两色，其背鳍起点位于鳃孔后缘的垂直线之后。这些特征与无鳍裸胸鳝、双色裸胸鳝、双齿裸胸鳝和东方裸胸鳝新种共有，但南海裸胸鳝的总椎骨数比其他两色物种少（南海裸胸鳝约120枚，其他四种为125 - 140枚）。来自越南的东方裸胸鳝与除双色裸胸鳝外的所有其他同属物种不同，其身体简单分为两色，头长（约占全长的10%），背鳍起点位置（明显在鳃孔后缘的垂直线之后），以及肛前椎骨和总椎骨数量（分别为35枚和135枚）。尽管东方裸胸鳝在可数性状和形态测量方面与双色裸胸鳝相似，但其色素沉着和拥有更粗壮的肌间骨不同。这些新物种代表了裸胸鳝属在西北太平洋和东印度洋的首次记录。
