摘要:

䶄亚科田鼠族(Microtini)是一个分布广、物种多、在分类学上存在争议也较多的类群。通常认为该族在全世界有10属81种,中国有7属24种。近年来,通过广泛采集标本,开展分类与系统发育研究,基本厘清了我国䶄亚科田鼠族分类与系统发育问题。确认田鼠族在全世界仅8属,分别是东方田鼠属(Alexandromys)、雪田鼠属(Chionomys)、毛足田鼠属(Lasiopodomys)、艾草田鼠属(Lemmiscus)、田鼠属(Microtus)、松田鼠属(Neodon)、沟牙田鼠属(Proedromys)和川西田鼠属(Volemys)。帕米尔田鼠属(Blanfordimys)被证明是田鼠属的亚属,白尾松田鼠属(Phaiomys)是松田鼠属
的同物异名,水䶄属(Arvicola)被证明不属于田鼠族。而东方田鼠属是从田鼠属的亚属提升为属。中国田鼠族包括6属26种。青海毛足田鼠(Lasiopodomys fuscus)、白尾松田鼠(Phaiomys leucurus)和克氏田鼠(Microtus clarkei)均是松田鼠属成员。凉山沟牙田鼠(Proedromys liangshanensis)、林芝松田鼠(Neodon linzhiensis)、聂拉木松田鼠(Neodon nyalamensis)和墨脱松田鼠
Neodon medogensis)是近年来命名的新种。

Abstract:

The speciose tribe Microtini has a very wide distribution. Much controversy exists on the taxonomy and phylogenetic relationships. Historically, ten genera and 81 species have been assigned to Microtini, among which 7 genera and 24 species were reported from China. Through extensive field collection and systematic studies, we revise the phylogeny of this tribe and its taxonomy of this taxon in China by integrating molecular and morphological data. Results confirm 8 genera in Microtini worldwide: Alexandromys, Chionomys, Lasiopodomys, Lemmiscus, Microtus, Neodon, Proedromys and Volemys. Blanfordimys was confirmed as a subgenus of Microtus, and Phaiomys as a junior synonym of Neodon and Alexandromys was elevated as full genus rank. Arvicola was excluded from Microtini. Thus, China has 6 genera and 26 species of Microtini. Lasiopodomys fuscus, Phaiomys leucurus and Microtus clarkei were reassigned to Neodon, and recent studies nominated recognition of Proedromys liangshanensis, Neodon linzhiensis, Neodon medogensis and Neodon nyalamensis.
