四川省国家级自然保护区的3个蚯蚓新物种
|
Abstract:
龙溪–虹口国家级自然保护区和栗子坪国家级自然保护区分别位于四川省西部和南部，属中亚热带湿润季风气候区，该区域物种多样性丰富，目前国内针对该区域内蚯蚓的物种多样性研究相对较少。通过形态分类学方法和DNA条形码技术，本文报道了采集于龙溪–虹口国家级自然保护区的龙门远盲蚓(Amynthas longmenmontis Dong & Jiang sp. nov.)，栗子坪国家级自然保护区的暗色远盲蚓(Amynthas impolitus Dong & Qiu sp. nov.)和黄褐远盲蚓(Amynthas fulvidus Dong & Sun sp. nov.)蚯蚓新物种。它们的共同特征是受精囊孔4对，位于5/6~8/9节间，属于A. corticis物种群。
The Longxi-Hongkou National Nature Reserve and the Liziping National Nature Reserve are situated in the western and southern regions of Sichuan Province, belonging to the mid-subtropical humid monsoon climate zone. This region is characterized by its abundant diversity of species. However, domestic studies focusing on the species diversity of earthworms in this area are relatively scarce at present. By means of morphological taxonomy methods and DNA barcode technology, three new earthworm species belonging to genus Amynthas were found: A. longmenmontis Dong & Jiang, sp. nov., A. impolitus Dong & Qiu, sp. nov., A. fulvidus Dong & Sun, sp. nov. All of them have four pairs of spermatheca pores located in 5/6~8/9 belonging to the A. corticis-group.
