摘　　要：本文记述了发现于贵州的腔蚓属蚯蚓一新种和一新亚种,即叠管腔蚓Metaphire ptychosiphona sp.nov.和秉前腔蚓江口新亚种Metaphirepraepinguis jiangkouensis subsp.nov.。新种及新亚种的模式标本分别采于绥阳宽阔水和江口梵净山。The present paper reports one new species and one new subspecies of the genus Metaphire found in Guizhou Province, China. Type speci- mens are deposited ih Institute of Biology, Guizhou Academy of Sci- ences. Metaphire ptychosiphona sp. nov. (figs. 1) Length 196-295mm, diameter 6.0-9.0mm, segments 80-151. The first dorsal pore in 11/12. prostomium 1/2 epilobous. Clitellum in ⅩⅣ-ⅩⅥ, with some setae on its ventral side. Setae fine and close, evenly distributed. Setae numbers: 57-61/Ⅲ, 64-72/Ⅴ, 64-79/Ⅷ, 87-117/ⅩⅩ, 85-124/ⅩⅩⅤ; 27-31 (Ⅶ), 28-34(Ⅷ) betw- een spermathecal pores and 15-27(ⅩⅧ) between male pores. Male pore one pair, each situated in a rather shallow copulatory chamber on the ventro-lateral side of ⅩⅧ, about 1/3 of circumference ventrally apart. No papilla in or out of the copulatory chamber. Spermathecal pore three pairs in 6/7-8/9,each borded anteriorly and posteriorly by glandular lips, nearly 2/5 of circumference ventrally apart. No papilla in this region. Septa 8/9 membraneous, 9/10 absent. Caeca simple. Testis sacs two pairs, rather small, separated widely. Seminal vesicles in Ⅺ and Ⅻ, meeting dorsally. Diverticulum shorter than the main part, ental 3/5 twisted in close zigzag fashion. Holotype: GZ-Z00001 B_1, 196mm long, 9.0mm wide, 80 segments. setae numbers: 61/Ⅲ, 72/Ⅴ, 79/Ⅷ, 117/ⅩⅩ, 124/ⅩⅩⅤ; 31(Ⅶ), 34(Ⅷ) between spermathecal pores and 27(ⅩⅧ) between male pores, was col- lected from Kuan Kou Shui Forest Region (28°14′N, 107°09′E, Alt. 146m), Suiyang County, Guizhou Province on August 14, 1984. Para- type: GZ-Z00001B_2, GZ-Z00042D(4), five specimens, were collected at the same place as holotype on August 13-14, 1984. The present species is similar to Metaphire grahami (Gates 1935), but differs from the latter by the present of septa 8/9, the widely sepa- rated small testis sacs, the shallow and small copulatory chamber in or out of which no papilla and no papilla in spermathecal pore region. Metaphire praepinguis jiangkouen
