A new genus and species belonging to the subfamily Cypridopsinae, Neopotamocypris indivisa gen. nov. sp. nov., is described from Thailand. The new genus is the second one of the tribe Potamocypridini. Neopotamocypris gen. nov. is similar to Potamocypris but can be distinguished mainly by the undivided penultimate segment of the second thoracopod, the absence of the d1 seta on the third thoracopod and the morphology of the mandibular palp, maxillula and female genital hook. The discovery of the new genus suggests the morphological divergent evolution at generic level within the tribe and also perhaps constitutes an example of convergent evolution in the subfamily. The taxonomic characters of the tribe are briefly discussed.
从泰国描述了一个属于Cypridopsinae亚科的新属新种，即Neopotamocypris indivisa gen. nov. sp. nov.。新属是Potamocypridini族的第二个属。新属Neopotamocypris gen. nov.与Potamocypris相似，但主要可通过第二胸足倒数第二节未分开、第三胸足上没有d1刚毛以及下颌须、小颚和雌性生殖钩的形态来区分。新属的发现表明该族在属级水平上存在形态趋异进化，也可能构成亚科趋同进化的一个例子。简要讨论了该族的分类特征。
