A new species Macrobrachium ramae is described from Rupnarayana river, West Bengal, India along with its molecular characterization and Scanning electron microscopy. The species shares certain characters with M.gurudeve, M.jayasreei, M.kunjuramani and M.saengphani but differs remarkably from these species in the structure and shape of rostrum, telson, appendix masculina and in the size of the proximal segment of the antennular peduncle. Molecular characterization and phylogenetic analysis of M.ramae with mitochondrial COI and 16S rRNA genes reinforce the morphological conclusion and supports the view that it is a new species.
一种新物种——拉马沼虾（Macrobrachium ramae）在印度西孟加拉邦的鲁德纳拉亚纳河被发现，并对其进行了分子特征分析和扫描电子显微镜观察。该物种与古鲁德韦沼虾（M.gurudeve）、贾亚斯里沼虾（M.jayasreei）、昆朱拉马尼沼虾（M.kunjuramani）和森法尼沼虾（M.saengphani）具有某些共同特征，但在额剑、尾节、雄性附肢的结构和形状以及触角柄近端节的大小方面与这些物种有显著差异。利用线粒体COI和16S rRNA基因对拉马沼虾进行分子特征分析和系统发育分析，强化了形态学结论，支持了它是一个新物种的观点。
