A new species of atyid freshwater shrimp is described from two caves of Bac Kan Province, Northeast Vietnam, namely Caridina namdat sp. nov. This species can be distinguished from its congeners by a suite of morphological characters such as reduced eyes with short eyestalk, very short and unarmed rostrum, slender second pereiopod, elongated endopod of male first pleopod, and long appendix interna of the male second pleopod. Molecular phylogenetic data from the mitochondrial cytochrome oxidase subunit I (COI) and 16S ribosomal RNA genes also support the distinctiveness of the new species from all other examined species.
描述了来自越南北部东北部 Bac Kan 省的两个洞穴的一个新的淡水虾物种，即 Namdat 沼虾。该物种可以通过一系列形态特征与同属物种区分开来，例如眼睛缩小，眼柄短，短而无武装的额角，第二对步足细长，雄性第一对腹肢的内肢延长，以及雄性第二对腹肢的长内附肢。来自线粒体细胞色素氧化酶亚基 I (COI) 和 16S 核糖体 RNA 基因的分子系统发育数据也支持该新物种与所有其他检查物种的独特性。
