墨蚜蝇(双翅目,食蚜蝇科,食蚜蝇亚科)八种雄性外生殖器比较

作者对墨蚜蝇族中3属8种昆虫:东方墨蚜蝇Melanostoma orientale,方斑墨蚜蝇M.mellinum,梯斑墨蚜蝇M.scalare,天台墨蚜蝇M.tiantaiensis,黑腹宽跗蚜蝇Platycheirus albimanus,叉尾宽跗蚜蝇P.bidentatus,斜斑宽跗蚜蝇P.scutatus,圆斑宽扁蚜蝇Xanthandrus comtus进行了雄性外生殖器的比较研究,并分别予以绘图和描述。结果表明,雄性外生殖器在属内种间形态结构很相似,仅在尾器颜色、阳茎基部形状等方面有微小的区别;而在属间主要是背针突和上叶的形态和结构存在较大的不同。

COMPARATIVE STUDIES ON THE MALE GENITALIA OF EIGHT MELANOSTOMINI SPECIES (DIPTERA, SYRPHIDAE, SYRPHINAE)

Comparative study on the male external genitalia of eight species in three genera of Melanostomini, Melanostoma orientale, M. mellinum, M. scalare, M. tiantaiensis, Platycheirus albimanus, P. bidentatus, P. scutatus, Xanthandrus comtus(Diptera, Syrphidae, Syrphinae), are male. The results show that structures of the male external genitalia of different species in the same genus are similar, but there are still a few among differences in the colour of the genitalia and the shap of aedeagus base. The structures of the male external genitalia are variable distinctly to different genera, especially the shap of the styles and superior lobe.
