Cymodoce waegelei sp. nov. is described from the subtidal zone of the Iranian coasts of the Persian Gulf using both morphological and molecular data. C. waegelei sp. nov. is most similar to C. tribullis Harrison & Holdich, 1984 from Australia, Vietnam and Singapore. Analysis of DNA barcodes and nuclear 28S rDNA: D8 expansion segments clearly support the existence of two distinct species. Cymodoce waegelei sp. nov morphologically differs from C. tribullis by lacking two continuous rows of tubercles on the pereonites 3 and 4. Moreover, the pleotelson has numerous scattered tubercles between two large prominent bosses, and small lateral tubercles rather than two prominent tubercles in C. tribullis. Based on our results we redescribe Cymodoce tribullis using specimens sampled from the type locality, Magnetic Island, Queensland. Cymodoce lirella Schotte & Kensley, 2005 from the Seychelles is placed in synonymy with C. tribullis Harrison & Holdich 1984. Furthermore we provide a key to the northern Indian Ocean species of this genus.
利用形态学和分子数据，对来自波斯湾伊朗海岸潮下带的新物种瓦氏瑟莫多蟹（Cymodoce waegelei sp. nov.）进行了描述。瓦氏瑟莫多蟹与来自澳大利亚、越南和新加坡的1984年发现的哈氏瑟莫多蟹（C. tribullis Harrison & Holdich）最为相似。对DNA条形码和核28S rDNA：D8扩展片段的分析明确支持存在两个不同的物种。瓦氏瑟莫多蟹在形态上与哈氏瑟莫多蟹的区别在于，其第3和第4胸节上没有两排连续的瘤。此外，其尾节在两个大的突出瘤之间有许多分散的瘤，以及小的侧瘤，而不是哈氏瑟莫多蟹中的两个突出瘤。基于我们的研究结果，我们使用从昆士兰磁岛模式产地采集的标本重新描述了哈氏瑟莫多蟹。来自塞舌尔的2005年发现的细纹瑟莫多蟹（Cymodoce lirella Schotte & Kensley）被置于哈氏瑟莫多蟹（C. tribullis Harrison & Holdich 1984）的同义名下。此外，我们提供了该属印度洋北部物种的检索表。
