Abstract

Tritodynamia bengalensis n. sp. is described on the basis of a male specimen dredged from the shallow coastal waters of West Bengal state, India. The new species is morphologically similar to T. bidentata Yang Tang, 2005 and T. serratipes Anker Ng, 2014, but can be distinguished by the carapace shape, dentition of the pollex, relative length of the dactylus of the third maxilliped, proportions of the propodus of the third pereopod, and structure of the male left gonopod. This is the first record of the genus Tritodynamia from India.

摘要

孟加拉三力蟹新种（Tritodynamia bengalensis n. sp.）是根据从印度西孟加拉邦浅海沿海水域 dredged 出的一只雄性标本描述的。该新种在形态上与2005年的双齿三力蟹（T. bidentata Yang Tang）和2014年的锯齿足三力蟹（T. serratipes Anker Ng）相似，但可通过头胸甲形状、拇指齿列、第三颚足指节的相对长度、第三步足腕节的比例以及雄性左生殖肢的结构来区分。这是印度三力蟹属的首次记录。
