摘　　要：本文报道了发现于贵州的远盲属和腔蚓属蚯蚓三个新种,即雅致远盲蚓Amyntas eleganus sp.nov,大突远盲蚓Amynthas megapapillatus sp.nov.和贵州腔蚓Metaphire guizhouense sp.nov.前两个新种的模式标本采于贵州省梵净山,后一个新种的模式标本采于贵州省雷公山。1. Amynthas eleganus sp. nov. (figs. 1-3) Length 75-123mm, diameter 3.5-4.0mm, segments 81-107 (holotype: 123mm long, 4.0mm wide, 101 segs.) Prostomium 1/3 epilobous. Clitellum red-brown, with setae on ventral side. Setae fine , their numbers: 22-34/Ⅲ, 33-42/Ⅴ, 32-46/ⅤⅢ, 42-48/ⅩⅩ, 42-50/ⅩⅩⅤ; 16-19(Ⅷ) between spermathecal pores and 7-10(ⅩⅧ) between male pores [holotype: 22/Ⅲ, 33/Ⅴ, 32/Ⅷ, 45/ⅩⅩ, 49/ⅩⅩⅤ; 16(Ⅷ); 8 (ⅤⅧ)]. Male pores on ventro-lateral sides of ⅩⅧ, each on a small round papilla, other three genital papillae close to porophore. Spermathecal pores one pair in 7/8, about 4/9 of circumference ventrally apart. There are two pairs of papillae on ventral side of Ⅹ and Ⅺ or four pairs on Ⅸ-Ⅻ. Septa 8/9 and 9/10 lacking, rather thin. Caeca compound, with 5-9 long finger-shaped pounches on ventral side, in ⅩⅩⅦ-ⅩⅦ. Testis sacs two pairs in Ⅹ and Ⅺ, communicated. Seminal vesicles in Ⅺ and Ⅻ, well developed. Prostate glands large in ⅩⅦ-ⅩⅩ. There are a group of small accessory glands in this region, each with a small stalk. Spermathecae in Ⅷ, ampulla heart-shaped. Diverticullum longer than the main part, terminal half part twisted. Having accessory glands in this region. Holotype and 5 paratypes were collected from Mt. Fanjin (27°49'N, 108°46'E), Guizhou, China in June 1, 1985 and May 28-31, 1985. The new species is similar to Amynthas palmosa (Chen 1946), but differs from the latter by the following characters: (1) Male pore on a smll papilla with other three papillae close to it; (2) Caeca compound, but not in palmate; (3) Diverticullum longer than the main part, terminal half part in weak or closed zigzag fashion; (4) Accessory glands well developed, each with a small stalk. 2. Amynthas megapapillatus sp. nov. (figs. Ⅰ-4-8) Length 84-167mm, diameter 3.5-4.0mm, segments 76-103 (holotype: 167mm long, 4.0mm wide, 103 segs.). Prostomium 1/3 epilobous. First dorsal pore in 12/13. Clitellum in ⅩⅣ-ⅩⅥ, without setae o
