摘　　要：本文用扫描电镜观察了马颈颚虱亚科的2种马颈颚虱和1种拟马颈颚虱的口管、口部附肢和附着器官。结合光镜观察,修正了以前对下唇构造的描述,并从形态结构对摄食功能进行了探讨。Tracheliastes and Pseudotracheliastes are two genera belonging to the subfamily Tracheliastinae of the family Lernaeopodidae. In China four species of Tracheliastes and one species of Pseudotracheliastes are involved. In present paper, Tracheliastes polycolpus, T. brevicorpus and Pseudotracheliastes soldatovi yangtzensis are selected as representatives of two genera, by using scanning electron microscopy (SEM) for the first time. The result of observation on the structure of labrum and labium is not the same in comparison with the result under the light microscope. The lateral side of labium is single in form and does not divide into two lobes. Consequently the authors revised this structure as above described. As others, no conspicuous difference is observed.
