A new pseudocryptic species of fiddler crab, , is described from the northern Indian Ocean. The new species was previously identified with (H. Milne Edwards, 1852), but can be distinguished by the structures of the anterolateral angle of the carapace and male first gonopod. The molecular data of the mitochondrial cytochrome oxidase subunit I gene shows that both are sister taxa and the divergence time is estimated at 2.2 million years ago, around the beginning of the Pleistocene. While the new species is widely distributed in the northern part of Indian Ocean, occurring from the Red Sea to India and the Andaman Sea; sensu stricto has a more restricted range, and is known only from southeastern Africa.
一种新的隐螯蟹属招潮蟹物种被描述于印度洋北部。该新物种之前被鉴定为（H. 米尔恩·爱德华兹，1852年），但可通过头胸甲前侧角和雄性第一生殖肢的结构加以区分。线粒体细胞色素氧化酶亚基I基因的分子数据表明二者是姐妹分类群，分歧时间估计在220万年前，大约是更新世开始之时。新物种广泛分布于印度洋北部，从红海至印度及安达曼海；严格意义上的（某种蟹）分布范围更窄，仅见于非洲东南部。
