Lobothorax bharat sp. nov., is described based on specimens collected in 2023 from Trichiurus lepturus Linnaeus, 1758, at the Bahabalpur and Gopalpur fish landing centres of Odisha coast, India. Lobothorax bharat sp. nov. can be identified by the sub-truncate rostrum; the anterolateral processes of pereonite 1 which are 0.45 times the cephalon length, do not extend beyond the anterior margin of cephalon; a distinct depression in the middle of pereonite 1; article 3 of maxilliped palp with three recurved robust setae; the pereopod 2 is larger than the first and the pereopod 3 being the smallest; the third pereopod is about 0.94 times that of the second and 0.97 times that of the first pereopod. Lobothorax bharat sp. nov. is further differentiated from the congeneric species L. typus in the nucleotide composition of the mitochondrial cytochrome c oxidase I (mtCOI) gene by 2.5-2.6% Kimura-2-Parameter (K2P) distance (having a base pair difference of 16-17) and belongs to a separate cluster in the Maximum Likelihood tree analysis obtained through the best-fit model.
印度新叶胸虾（Lobothorax bharat sp. nov.）是根据2023年在印度奥里萨邦海岸的巴哈巴尔布尔和戈帕尔布尔鱼类上岸中心从带鱼（Trichiurus lepturus Linnaeus，1758）身上采集的标本描述的。印度新叶胸虾可通过以下特征识别：亚截形的吻部；第1胸节的前侧突长度为头部长的0.45倍，不超出头部前缘；第1胸节中部有明显凹陷；颚足触须第3节有三根弯曲的粗壮刚毛；第2步足比第1步足大，第3步足最小；第3步足约为第2步足的0.94倍，第1步足的0.97倍。印度新叶胸虾在细胞色素c氧化酶亚基I（mtCOI）基因的核苷酸组成上与同属的典型叶胸虾（L. typus）进一步区分，其Kimura-2-参数（K2P）距离为2.5-2.6%（碱基对差异为16-17），并在通过最佳拟合模型获得的最大似然树分析中属于一个单独的聚类。
