摘　　要：作者系统整理了中国管螺属Ｐｈａｅｄｕｓａ的标本和有关资料，已知我国管螺属计有２２种，其中发现有３新种，即峨嵋管螺Ｐｈａｅｄｕｓａｅｍｅｉｅｎｓｉｓｓｐ．ｎｏｖ．、丹巴管螺Ｐｈａｅｄｕｓａｄａｎｂａｅｎｓｉｓｓｐ．ｎｏｖ．和三门管螺Ｐｈａｅｄｕｓａｓａｎｍｅｎｅｎｓｉｓｓｐ．ｎｏｖ．。本文对旧有的种进行了整理和甄别，对新种的形态特征作了详细的描述，并与近似种进行了比较。Phaedusa H. & A. Adams 1855 is a genus of the Oriental Realm. Most species of the genus are recorded from East and East Southern Asia and Southern China. The present paper reports the result of studies on the genus from China. It comprises 22 species, including 3 new species. All type specimens are deposited in the Institute of Zoology, the Chinese Academy of Sciences, Beijing, China.1 Phaedusa emeiensis sp. nov. \ (Fig.1) Holotype (SI64088) length 15.1mm, breadth 3.9mm; length of aperture 3.9mm, breadth of aperture 3.9mm; Emei County (29°45′ N, 103°17′ E), Sichuan Province, China; August 8, 1964. Paratypes 29 specimens, length 14.7 15.3 mm, breadth 4 4.3 mm; lenght of aperture 3.6 3.9 mm, breadth of aperture 3.0 3.2 mm; Emei County (29°45′N, 103°17′E), Sichuan Province, China; August 8, 1964. Shell small, thick, conocidal, whorls 912, well convex. The surface dark brown, with deep suture, short fusiform. Apex acuminate. Body whorl contracted. Aperture small, pyriform, peristome white, thick, expanded and reflected. Superior lamella visible in aperture, and reaches the peristome. The principal plica and lunella plica long, with 4 plicae palatales at the last whorls and from the right parielal wall in lateral view. The clausilium slender tongue shaped, pedicle long. This new species differs from the closely related species Phaedusa pseudobensoni (Schmacker & Boettger, 1894) in the shape of suture, superior plica, lunella plica and clausilium.2 Phaedusa danbaensis sp. nov. (Fig.2) Holotype (SI640712) length 15.0mm, breadth 4.1mm; length of aperture 4.0mm, breadth of aperture 3.1mm., Zhanggu Town, Danba County (30°58′N, 101°35′E), July 12, 1964. Paratypes 37 specimens, length 14.1 15.0 mm, breadth 3.9 4.2 mm; length of aperture 3.9 4.2 mm breadth of aperture 2.8 3.3 mm, Zhanggu Town, Danba County (30°58′N, 101°35′E), July 12, 1964. Shell small, thick, solid, short fusiform conoidal, whorls 912, well conve
