The identity of the widely distributed mangrove and riverine sesarmid crab (H. Milne Edwards, 1837) is clarified. The species has been reported from Madagascar to the South Pacific, but its taxonomy was previously confused. On the basis of morphological characters and available molecular evidence (using 16S rDNA and cytochrome oxidase subunit I), is restricted to the western Indian Ocean and A. Milne-Edwards, 1869 is confirmed to be its junior synonym. (Hess, 1865), long synonymised under , is here recognised as a separate species and a neotype from Samoa is designated. The identity of the poorly known (Hess, 1865), which has often been confused with , is also clarified, and a neotype is selected from Fiji. Specimens from the eastern Indian Ocean and western Pacific are here identified as two new species, sp. nov. and sp. nov.
广泛分布的红树林和河川相相手蟹(H. Milne Edwards,1837年)的身份得以厘清。该物种已在从马达加斯加至南太平洋的地区被报道,但它之前的分类学存在混淆。基于形态特征和现有分子证据(使用16S rDNA和细胞色素氧化酶亚基I),其范围限定于西印度洋,并且确认A. Milne-Edwards,1869年是其次异名。(Hess,1865年),长期以来被视为的同物异名,在此被认定为一个独立物种,并指定来自萨摩亚的一个新模标本。鲜为人知的(Hess,1865年)的身份也得以厘清,它常与混淆,并且从斐济选择了一个新模标本。来自东印度洋和西太平洋的标本在此被鉴定为两个新物种,新物种1和新物种2。
