| 摘 要： | 对脊虎天牛属Xylotrechus的雄性外生殖器进行了比较解剖研究，描述了该属7个种的雄性外生殖器特征。结果表明，脊虎天牛属雄性外生殖器的结构特征具有重要的分类学价值，其交配孔腹缘形态在属内是稳定的，具有属级分类学意义；阳基侧突、中茎的结构及内囊骨化物的特化具有高度的稳定性，是重要的分种性状。

| Abstract: | A comparative anatomic study on the male genitalia of the genus Xylotrechus Chevrolat was performed,and the characteristics of the male genitalia of 7 species were described. The results showed that the characteristics of male genitalia were confirmed to be valuable for the classification of Xylotrechus. The shape of the ventral margin of median orifice was stable within the genus and possessed generic taxonomic significance. Besides the structures of the median lobe and the lateral lobes, the difference in the shape of the armature of the internal sac which showed a high degree of stability was proved to be a valuable character in classifying species. |
