摘要台湾灰鼩（Crocidura tanakae）与亚洲灰鼩（C. attenuata）在大小和形态上非常相似，以至于台湾灰鼩的分类地位自被描述以来发生了多次变化；田中花也被认为是台湾岛的特有种。近年来，通过分子鉴定在中国大陆发现了多篇田中的报道。本研究基于2000年至2018年在中国大陆采集的100多个标本，确定了中国大陆两种植物的地理分布，并对其分布进行了实质性的修正。在110个个体中，经Cytb基因和形态鉴定，分别有33个衰减和77个tanakae。结果表明，(1)中国大陆的衰减C.和田中C.具有明显的对称分布特征；(2)与文献报道相反，在中国大陆，淡叶卷叶蝉的分布范围有限，远小于田中卷叶蝉；(3)海南岛与台湾岛一样，仅根据现有资料，存在田中种。
Abstract The Taiwanese gray shrew (Crocidura tanakae) and Asian gray shrew (C. attenuata) are so similar in size and morphology that the taxonomic status of the former has changed several times since its description; C. tanakae has also been regarded as an endemic species of Taiwan Island. In recent years, molecular identification has led to several reports of C. tanakae being distributed in the mainland of China. In this study, we determine the geographical distribution of C. attenuata and C. tanakae based on more than one hundred specimens collected during 2000 to 2018 over a wide area covering the traditional ranges of the two species in the mainland of China, and show a substantial revision of their distributions. Among 110 individuals, 33 C. attenuata and 77 C. tanakae were identified by Cytb gene and morphologies. Our results show, (1) C. attenuata and C. tanakae are distributed sympatrically in the mainland of China; (2) contrary to the previous reports, the distribution range of C. attenuata is restricted and much smaller than that of C. tanakae in the mainland of China; (3) Hainan Island, like Taiwan Island, is inhabited by C. tanakae only according to the present data.
