| 摘 要： | 该文就狭胸天牛类3属6种雄性外生殖器的形态结构，比较研究其系统发育及其归属，并记录太谷芫天牛Mantitheus tazguensts sp. nov.一新种和重新描述细点音天牛的雄性外生殖器。狭胸天牛类属较原始的类群，祖征为中茎突中央加厚，边缘极薄；阳基侧突基部还保留着一条横裂。狭胸天牛属与音天牛属和芫天牛属关系较密切，应为姊妹群，狭胸天牛属较始，其衍征为中茎突较长的分开，内囊具基骨片、骨化细长管和大小较一致骨化微刺。音天牛属和芫天牛属为姊妹群，芫天牛较原始，音天牛较进化，其衍征为阳基侧突背面因基部裂缝消失而完全合并，骨化细长管较细；外部形态表现为触角较短，较圆；中胸发音器中央无缝；而芫天牛内囊基骨片明显易见。

| Abstract: | A comparative anatomical study of male genitalia of species of philid beeles was performed. The characteristics of male genitalia were confirmed to be valuable for the classification of philid beeles. Besidesthe structure of the median lobe and the lateral lobe, the difference in the shape of the armature of the internal sac which shows a high degree of stability was proved to be a valuable character in separating generaand species. The characteristics of male genitalia of 3 genera, 6 species including a new species, Philusantennatus (Gyllenhal), Philus pallescens Bates, Mantitheus pekinensis Fairmaire, Mantitheus gracilis Pic, Mantitheus taiguensis sp. Nov. and Heterophilus punctulatus Chiang, Chen et Zhang were described. According to the characters of the male genitalia, a phylogenetic tree of these genera is advanced. |
