Three new earthworms of the Amynthas corticis-group (Clitellata: Megascolecidae) from Phouleoi Mountain, Lao PDR. Earthworm specimens were collected from Mt. Phouleoi, Viengthong District, Houaphanh Province, Lao PDR. The species belong to the pheretimoid earthworms. All three holandric species key out to the A. corticis-group in Sims & Easton (1972), having spermathecal pores in 5/68/9. The new species are: Amynthas ammalinei sp. nov., Amynthas xayi sp. nov., and Amynthas piyakarnae sp. nov. Amynthas ammalinei sp. nov. has male pores superficial on small round porophores, 0.160.31 circumference apart. Amynthas xayi sp. nov. has male pores superficial in XVIII at centers of round porophores, 0.170.29 circumference apart. Amynthas piyakarnae sp. nov. has male pores superficial on transverse elevated elongate oval pads equatorial on XVIII, pads surrounded by 34 small outer rings, 0.250.31 circumference apart.
来自老挝普莱奥山的 Amynthas corticis 组（Clitellata：Megascolecidae）三种新蚯蚓。蚯蚓标本采自老挝华潘省丰通县普莱奥山。这些物种属于pheretimoid 蚯蚓。所有三种两性异形物种都与 Sims 和 Easton（1972）中的 A. corticis 组相匹配，具有 5/68/9 的精囊孔。新物种是：Amynthas ammalinei sp. nov.，Amynthas xayi sp. nov. 和 Amynthas piyakarnae sp. nov. Amynthas ammalinei sp. nov. 的雄性孔位于小圆形 porophores 的表面，间隔 0.160.31 周长。Amynthas xayi sp. nov. 的雄性孔位于 XVIII 中心的圆形 porophores 的表面，间隔 0.170.29 周长。Amynthas piyakarnae sp. nov. 的雄性孔位于 XVIII 赤道处的横向隆起的长椭圆形垫上，垫被 34 个小外环包围，间隔 0.250.31 周长。
