Nine new species of Amynthas (Clitellata: Megascolecidae) from Mt. Phouleoi, Lao PDR: Earthworm specimens were collected on the top of Mt. Phouleoi, Viengthong District, Houaphanh province, Lao PDR. The new species belonged to pheretimoid earthworms. They have spermathecal pores in 7/8 and 8/9, corresponding to the aeruginosus-group as characterized by Sims and Easton (1972). Their names are: Amynthas bouatongi sp. nov., Amynthas hoauykanangensis sp. nov., Amynthas phimpheti sp. nov., Amynthas nametensis sp. nov., Amynthas somechanae sp. nov., Amynthas wiggeri sp. nov., Amynthas fleischmani sp. nov., Amynthas antethecus sp. nov., and Amynthas elenabondae sp. nov. With the exception of A. nametensis sp. nov., all have the first dorsal pore in an unusually anterior location close to 5/6 and very large, often coiled, prostatic ducts. Several species have slight intraparietal invaginations of the primary male pores, but the similarity of other characters leads us to include them in Amynthas rather than in a polyphyletic Metaphire. Amynthas bouatongi sp. nov. has male pores 0.20-0.24 circumference apart on reniform male pads, pair genital papillae medial and lateral to male pores in XVIII. Amynthas hoauykanangensis sp. nov. has openings of copulatory pouches 0.19-0.25 circumference apart, and paired round genital papillae on postsetal XVII and presetal XIX in line with the male pores. Amynthas phimpheti sp. nov. has male pores 0.21-0.24 circumference apart, round thickened genital papillae paired on 17/18 and 18/19 in line with male pores. Amynthas nametensis sp. nov. has male pores superficial on thickened circular pads, 0.24-0.27 circumference apart. Amynthas somechanae sp. nov. has male pores 0.20-0.33 circumference apart, and paired equatorial papillae in XVIII. Amynthas wiggeri sp. nov. has male pores 0.22-0.30 circumference apart, paired genital papillae equatorial on XVIII medial to male pores and paired papillae equatorial in XVII and XIX. Amynthas fleischmani sp. nov. has openings of copulatory pouches 0.24 circumference apart, paired conical genital papillae equatorial on XVII and XIX; paired circular papillae in intersegmental furrows of 17/18 and 18/19. Amynthas antethecus sp. nov. has openings of copulatory pouches 0.31 circumference apart, paired circular papillae in intersegmental furrow of 17/18 and equatorial on XIX, slightly medial to secondary male pores. Amynthas elenabondae sp. nov. has openings of copulatory pouches 0.19 circumference apart, crescent, convex medially; primary male pore on tubercle on lateral wall of shallow parietal invagination.
老挝富勒伊山的9种环毛蚓新物种（寡毛纲：巨蚓科）：蚯蚓标本采自老挝华潘省维恩通县富勒伊山山顶。这些新物种属于类远盲蚓属蚯蚓。它们的受精囊孔位于7/8和8/9节，与西姆斯和伊斯顿（1972年）所描述的铜绿蚓类群特征相符。它们的名称分别是：布阿通环毛蚓新种、霍伊卡南环毛蚓新种、菲姆费蒂环毛蚓新种、纳梅滕环毛蚓新种、索梅查纳环毛蚓新种、维格里环毛蚓新种、弗莱施曼环毛蚓新种、前栖环毛蚓新种和埃莱娜邦德环毛蚓新种。除纳梅滕环毛蚓新种外，其他所有物种的第一背孔位置异常靠前，靠近5/6节，且前列腺管非常大，常呈盘绕状。几个物种的初级雄孔有轻微的体壁内陷，但其他特征的相似性使我们将它们归入环毛蚓属，而非多系的后孔蚓属。布阿通环毛蚓新种的雄孔在肾形雄垫上相距0.20 - 0.24节周，在第18节有位于雄孔内侧和外侧的成对生殖乳头。霍伊卡南环毛蚓新种的交配囊开口相距0.19 - 那么 0.25节周，在第17节后刚毛和第19节前刚毛处有与雄孔成排的成对圆形生殖乳头。菲姆费蒂环毛蚓新种的雄孔相距0.21 - 0.24节周，在17/18和18/19节有与雄孔成排的成对圆形加厚生殖乳头。纳梅滕环毛蚓新种的雄孔位于加厚圆形垫的表面，相距0.24 - 0.27节周。索梅查纳环毛蚓新种的雄孔相距0.20 - 0.33节周，在第18节有成对的赤道乳头。维格里环毛蚓新种的雄孔相距0.22 - 0.30节周，在第18节有位于雄孔内侧的成对赤道生殖乳头，在第17节和第19节有成对的赤道乳头。弗莱施曼环毛蚓新种的交配囊开口相距0.24节周，在第17节和第19节有成对的赤道锥形生殖乳头；在17/18和18/19节间沟有成对的圆形乳头。前栖环毛蚓新种的交配囊开口相距0.31节周，在17/18节间沟有成对的圆形乳头，在第19节有赤道乳头，略位于次级雄孔内侧。埃莱娜邦德环毛蚓新种的交配囊开口相距0.19节周，呈新月形，内侧凸起；初级雄孔位于浅体壁内陷侧壁的瘤上。
