The present study is a part of long term ongoing study on brachyuran crab diversity of India. The specimens were collected from intertidal zone as well as from the fisheries by-catch captured using commercial trawler. The specimens were identified up to species level using standard literature. From the collection, four species of brachyuran crabs, Schizophrys pakistanensis Tirmizi & Kazmi, 1995 (Majidae), Macromedaeus voeltzkowi (Lenz, 1905) (Xanthidae), Pseudosesarma brehieri Ng, 2018 (Sesarmidae) and Ilyograpsus paludicola (Rathbun, 1909) (Macrophthalmidae) are first time reported from India. The present study records significant expansion in the distribution range of these species. The diagnostic characteristics and remarks on the taxonomy and distribution of each species are given in this paper.

目前的研究是对印度短臂蟹多样性的长期研究的一部分。从潮间带以及使用商业拖网渔船捕获的渔业副渔获物采集标本。使用标准文献将标本鉴定到物种水平。从该物种的集合中，发现了四种短壳蟹，分别是Schizophrys pakistanensis Tirmizi＆Kazmi，1995（Majidae），Macromedaeus voeltzkowi（Lenz，1905）（Xanthidae），Pseudosesarma brehieri Ng，2018（Sesarmidae）和Ilyograpsus paludicola（Rathbun，1909）（Macrophthalmidae）是印度首次报道。本研究记录了这些物种分布范围的显着扩大。给出了每种物种的分类和分布的诊断特征和说明。
