Abstract: Species of Cathaica are widespread in the temperate montane regions of China, exhibiting high diversity and a broad spectrum of shell morphologies that reflect adaptation to heterogeneous environments. Here we describe three new Cathaica species from the Taihang Mountains of Henan and Hebei, China: Cathaica sculptilis Wang, Chen, He & Zhang, sp. nov., C. zhangcunxiangi Wang, Chen, He & Zhang, sp. nov., and C. wangjiaxuni Wang, Chen, He & Zhang, sp. nov. Two of these, C. sculptilis sp. nov. and C. wangjiaxuni sp. nov., share shell features with C. multicostata G. Zhang, 2023. Integrative morphological and molecular analyses support recognition of all three new species. The genital anatomical information of C. mengi is also provided for the first time.
摘 要：华蜗牛属 Cathaica Möllendorff, 1884 的物种广泛分布于中国温带山地地区，它们表现出高度的多样性，并演化出多种形态以适应不同的环境。其中一些物种具有特化的外壳形态以适应特殊的环境，并且在其分布区及周边区域未发现形态相似的物种。例如，多肋华蜗牛 C. multicostata Zhang, 2023 和孟氏华蜗牛 C. mengi Yen, 1939，具有粗壮的肋和明显突出的龙骨。在本研究中，我们基于采自太行山区的标本，描述了华蜗牛属的三个新物种：雕刻华蜗牛 C. sculptilis Wang, Chen, He & Zhang, sp. nov.、张氏华蜗牛 C. zhangcunxiangi Wang, Chen, He & Zhang, sp. nov. 和王氏华蜗牛 C. wangjiaxuni Wang, Chen, He & Zhang, sp. nov.。这些新种在外壳上相似，都具有比较低矮的螺塔和突出的龙骨，但生殖器解剖与分子系统学的分析均支持这些新物种的独立性。同时为了更好地理解这些形态相似的物种之间的亲缘关系，我们还采集了周边地区的华蜗牛标本，对它们进行了形态学和分子系统学的研究，并对孟氏华蜗牛 C. mengi 进行了形态重新描述和生殖器补充描述。
