Abstract

Paludomidae Stoliczka, 1868 are a group of freshwater snails widely distributed in Africa, South Asia, and Southeast Asia. In China, this family has only been recorded from southern Zangnan, Xizang Autonomous Region. Here we report the first reliable record of Paludomidae from the Irrawaddy River Basin in Yingjiang County of Yunnan Province, China. Based on an integrative study that integrates morphology, anatomy and molecular phylogenetic analyses of COI markers and partial mitochondrial genomes, a new species of Paludomus, Paludomus jingpo Zhang sp. nov., is described and compared with related Paludomus species from Myanmar, especially Paludomus regulata.

Key words: Freshwater snail, Irrawaddy River Basin, molecular phylogeny, Paludomus, taxonomy

摘 要

沼蜷科（Paludomidae）是一类广泛分布于非洲、南亚和东南亚淡水螺，在中国该科此前仅在西藏的藏南南部有记录。本文报道了云南省首次可靠记录的沼蜷科物种，发现于盈江县的伊洛瓦底江流域。基于形态学、解剖学以及 COI 分子标记和部分线粒体基因组的系统发育分析的综合研究，本文描述了一沼蜷科沼蜷属新物种——景颇沼蜷 Paludomus jingpo Zhang sp. nov.，并将其与缅甸的相关种类，特别是齐纹沼蜷 Paludomus regulata，进行了比较。
