This article is based on the nine specimens of milk sole, Aseraggodes kobensis (Steindachner 1896), collected from the Andaman waters. The present work happens to be the first geographical record of A. kobensis in the northeastern Indian Ocean. This record from off the Andaman coast bridges an apparent gap in the geographical distribution of milk sole in the Indo-Pacific biogeographic region. Phenotypic characters were enumerated and compared with the voucher specimens from the original description, Arabian Sea, and Malaysia hence proving the morphological identification. The key distinguishing characteristics of A. kobensis from congeners were the smaller head length and slender tendrils at the anterior tip of the snout and chin. A short standardized Mitochondrial Cytochrome c oxidase subunit 1 (COI) gene was targeted to generate the sequence for molecular taxonomy. A 629 bp long sequence was obtained and submitted to GeneBank as the first barcode from Indian waters (GeneBank accession number: OR568995). Maximum likelihood phylogenetic tree showed a distinct clade of Andaman isolate of A. kobensis with other species of the family Soleidae. A redescription of A. kobensis based on the morphological and molecular analysis has been presented in this article.

本文基于从安达曼水域采集的九个乳鳎鱼Aseraggodes kobensis (Steindachner 1896) 样本。目前的工作恰好是印度洋东北部A. kobensis的第一份地理记录。来自安达曼海岸的这一记录弥补了印度-太平洋生物地理区域乳鳎目地理分布的明显差距。列举了表型性状，并与原始描述、阿拉伯海和马来西亚的凭证标本进行了比较，从而证明了形态学鉴定。科本猴与同类的主要区别特征是头部较短，口鼻部和下巴前端的卷须较细长。以一个短的标准化线粒体细胞色素 c 氧化酶亚基 1 (COI) 基因为目标，生成分子分类学序列。获得了 629 bp 长的序列并提交给 GeneBank，作为印度水域的第一个条形码（GeneBank 登录号：OR568995）。最大似然系统发育树显示，A. kobensis的安达曼分离株与 Soleidae 科的其他物种具有明显的进化枝。本文基于形态学和分子分析对A. kobensis进行了重新描述。
