Earthworm specimens collected from Yunnan Province, China were found to represent three new species of Megascolecidae: Amynthas demptus sp. nov., Amynthas lacustris sp. nov. and Metaphire reclusa sp. nov. A. demptus belongs to Amynthas hawayanus-group and has three pairs of spermathecal pores in 5/6-7/8. A. lacustris belongs to Amynthas morrisi-group and has two pairs of spermathecal pores in 5/6-6/7. M. reclusa has no spermathecal pores. A. demptus has no male pores. The male pores of A. lacustris are about 1/3 body circumference ventrally apart, with a presetal and a postsetal papilla medial to each pore, surrounded with two circular folds. The male pores of M. reclusa are in copulatory chambers at XVIII, with openings of copulatory chambers about 1/3 body circumference ventrally apart. In this paper, the morphological characters of the three new species are described. We also sequenced COI and 12S gene fragments of the holotypes and selected paratype specimens to provide molecular data.
隐匿远盲蚓新种（Amynthas demptus sp. nov.）、湖泊远盲蚓新种（Amynthas lacustris sp. nov.）和隐居后平蚓新种（Metaphire reclusa sp. nov.）。隐匿远盲蚓属于哈氏远盲蚓组，在5/6 - 7/8节有三对受精囊孔。湖泊远盲蚓属于莫里氏远盲蚓组，在5/6 - 6/7节有两对受精囊孔。隐居后平蚓没有受精囊孔。隐匿远盲蚓没有雄孔。湖泊远盲蚓的雄孔腹侧相距约1/3体周，每个雄孔内侧有一个前刚毛乳头和一个后刚毛乳头，周围有两个环形褶。隐居后平蚓的雄孔位于第XVIII节的交配腔内，交配腔开口腹侧相距约1/3体周。本文描述了这三个新物种的形态特征。我们还对模式标本和选定的副模式标本的COI和12S基因片段进行了测序，以提供分子数据。
