A new species of , sp. nov., is described from Guizhou Province, China, based on morphological and molecular evidence. The new species can be distinguished from its congeners by the following combination of characters: the smooth shell, only three smaller cusps of lateral teeth on the inner side, outer marginal teeth with eight flattened and rounded denticles, an ovipositor pore in females, and BW/H ≥ 80%, B/H = 76.8-82.3%. Molecular analysis based on partial mitochondrial COI and 16S rDNA also supports the systematic position of the new taxon.
本文基于形态学和分子证据，描述了产自中国贵州省的皱疤坚螺属（Radix）一新种。新种与近似种的区别在于：光滑的壳，内齿仅有 3 个较小的侧齿，外边缘齿有 8 个扁平而圆钝的小齿，雌性具产卵孔，BW/H≥80%，B/H=76.8-82.3%。基于部分线粒体 COI 和 16S rDNA 的分子分析也支持了新分类单元的系统地位。
