中文摘要：

记述了广西短脉纹石蛾属3个新种,即刺尾短脉纹石蛾（Cheumatopsyche acanthus,n.sp.）、微凹短脉纹石蛾（C.concav-iuscula,n.sp.）和平尾短脉纹石蛾（C.orthocercata,n.sp.）。刺尾短脉纹石蛾与产于越南的金短脉纹石蛾（C.kimOláh＆Jo-hanson）较为接近,但其第10节侧面观上下缘近平行,中叶呈尖刺状,侧叶明显宽于中叶;内茎鞘突长卵圆形;下附肢第2节细而直;可与后者区别。微凹短脉纹石蛾与产于福建的挂墩短脉纹石蛾（C.guadunicaLi）相似,但其第10节侧面观较长,约为其高的2倍;阳具腹面观由基部向端部逐渐变细,并在其最端部略加粗;阳具内茎鞘突侧面观近三角形;下附肢第2节侧面观基部2/3粗大,端部1/3细窄,并略向上弯曲,上缘具一细微凹切;可与后者区别。平尾短脉纹石蛾与产于越南的伊氏短脉纹石蛾（C.ecsediiOláh＆Johanson）相似,但第10节侧面观略呈四边形;阳具侧面观内茎鞘突略呈四边形,且其下缘略向上切入;下附肢第2节明显窄于第1节端部;可与后者区别。模式标本保存于南京农业大学昆虫标本馆。

英文摘要：

Three new species of Cheumatopsyche from Guangxi Zhuang Autonomous Region are described and illustrated：C.acanthus,n.sp.,C.concaviuscula,n.sp.and C.orthocercata,n.sp..Species C.acanthus,n.sp.is similar to C.kim Oláh Johanson from Vietnam,but it can be distinguished from the latter by the parallel upper and lower margins of segment Ⅹ in lateral view;endothecal process in lateral view is elongated oval;and the second joint of each inferior appendage is slender and straight.C.concaviuscula,n.sp.is close to C.guadunica Li from Fujian,China,but it can be distinguished from the latter by the length of segment Ⅹ about twice its height in lateral view;phallic apparatus is tapering from base to distal end;endotheca process in lateral view is somewhat triangular;the second joint of each inferior appendage is narrowed suddenly at distal 1/3.C.orthocercata,n.sp.is close to C.ecsedii Oláh Johanson from Vietnam,but differs from it in that segment Ⅹ and endotheca process in lateral view are quadrilateral;the latter bears with a shallow excision at its lower margin;the second joint of each inferior appendage is obvious narrower than the distal end of the first joint.The type specimens are deposited in Insect Museum of Nanjing Agricultural University.
