摘　　要：由于楔形潜吉丁Trachys cuneiferus Kurosawa,1959的原始描述过于简单,且缺少鉴别特征图,本文根据2018年在广西猫儿山国家级自然保护区采集的楔形潜吉丁标本。对其进行了形态重描述,并给出了详细的鉴别特征图和标本整体图。此外,对楔形潜吉丁及近似种(莎氏潜吉丁T.saundersi Lewis,1893、杂灌潜吉丁T.auricollis Saunders,1873和托里诺潜吉丁T.toringoi Kurosawa,1951)进行形态比较。结果表明,尽管纹饰高度相似,仍可根据头部和前胸背板的光泽、上唇长宽比、前胸腹板的形状、鞘翅侧缘、阳茎等特征将楔形潜吉丁与近似种区分。The original description of Trachys cuneiferus Kurosawa,1959 is simple and lack of key features as well as drawings.In this study,4 Trachys specimens(3 males and 1 female)were collected from the Maoershan National Nature Reserve(Guangxi Zhuang Autonomous Region)in 2018,and the specimens were identified as Trachys cuneiferus Kurosawa,1959.The morphological characteristics of T.cuneiferus were redescribed and compared to the similar species(T.saundersi Lewis,1893,T.auricollis Saunders,1873 and T.toringoi Kurosawa,1951).Moreover,the detailed feature pictures and the photographs of the species were provided.The results showed that although the villi among the Trachys species were highly similar,T.cuneiferus could be discriminated by the luster of head and pronotum,the length to width ratio of clypeus,the shape of prosternum,the lateral margin of elytron,and aedeagus.
