首次用电子扫描显微镜对甘肃、宁夏和内蒙地区的甘肃麻虻Ｈ．ｋａｎｓｕｅｎｓｉｓ、等额麻虻Ｈ．ｈｅｄｉｎｉ、土麻虻Ｈ．ｔｕｒｋｅｓｔａｎｉｃａ、低额麻虻Ｈ．ｕｓｔｕｌａｔａ的触角、尾器外部形态作了初步观察，并对尾器亚生殖板所含微量元素作了测析．结果表明，４种麻虻的触角、尾器形态及亚生殖板所含微量元素在种间有一定差别．但这种差别在同种内的稳定程度、异种间的变异幅度尚需重复比较观察．结果启示在麻虻分类中，其触角、尾器的超微结构及所含微量元素具有参考意义
The first time using scanning electron microscopy on Gansu, Ningxia and Inner Mongolia Mudgee H Kansuensis, equal to Mochi H hedini, soil mound H turkestanica, lower mochi The tentacles of ustulata and the external appearance of the caudal device were preliminarily observed, and the trace elements contained in the caudal subgenus were analyzed. The results showed that there were some differences among the four species of tentacles, the shape of tail organ and the content of trace elements in subgenus. However, this difference in the same species within the stability, the magnitude of variation between the need to repeat the comparative observation. The results suggest that in the classification of Mochi, its antennae, the end of the ultrastructure and contains trace elements with reference value
