The first stygobitic species of atyid freshwater shrimps from Vietnam is described from Cuc Phuong National Park, Northern Vietnam. Caridina thachlam sp. nov. can be distinguished from its congeners by a suite of morphological characters such as strongly reduced eyes without eyestalk, short and almost unarmed rostrum and slender pereiopods. 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 species that we have examined.
描述了来自越南北部古庞国家公园的越南北部第一种穴居淡水虾的螯虾。Caridina thachlam 新种可通过一系列形态特征与同属物种区分开来，例如眼睛极度退化没有眼柄，短而几乎无武装的额角和细长的步足。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种与我们所研究的所有其他种的独特性。
