Abstract

In this study, we describe two new species and one new subspecies from the Taihang Mountains and Yimeng Mountains: Cathaica heyuemingi Wang & Zhang, sp. nov., C. qiguo Wang, Huan & Zhang, sp. nov., and C. wangjiaxunae rubricliva Wang, Huan, Zhang & Chen, ssp. nov. These taxa are morphologically similar to C. fasciola (Draparnaud, 1801), and C. pyrrhozona (Philippi, 1847), but differ in several shell characters, genital structures, and ecological habits. Anatomical and phylogenetic analyses were conducted to clarify their taxonomic status, and the results support their distinctiveness. This study also expands the known species diversity of Cathaica in northern China.

Key words: Comparative morphology, anatomy, molecular phylogeny, taxonomy, northern China

摘 要

在本研究中，我们描述了太行山脉和沂蒙山脉的华蜗牛属的两个新物种和一个新亚种：何氏华蜗牛 Cathaica heyuemingi Wang & Zhang, sp. nov.，齐国华蜗牛 C. qiguo Wang, Huan & Zhang, sp. nov. 和王氏华蜗牛丹崖亚种 C. wangjiaxunae rubricliva Wang, Huan, Zhang & Chen, ssp. nov.。这些物种在形态上与条华蜗牛 C. fasciola (Draparnaud, 1801) 和微红带华蜗牛 C. pyrrhozona (Philippi, 1847) 略为相似，但在壳形细节，生殖器结构和生态习性上存在差异。为明确其分类地位，我们对它们进行了解剖学和系统发育学研究，研究结果支持了它们作为独立物种和新亚种的地位，并进一步丰富了华蜗牛属 Cathaica 在中国北方的物种多样性。
