摘　　要：用扫描电镜对毛囊蠕形螨一些微细结构进行了补充观察,首次描述了闭锁的雌、雄性生殖孔及尾部嵴状皮纹等结构。同时描述了毛囊蠕形螨的背基刺为铆钉形,触须跗节上的腹侧爪向腹侧弯曲。还观察了背足体毛、爪距(新命名)和股距等结构,并推测后者具有防止虫体受外力作用被动离开毛囊的功能。本文报道了一类外形与皮脂蠕形螨相似的毛囊蠕形螨,并提出了两者之间的鉴别方法。文中还讨论了口下板的结构,以及颚体长度的变化问题。Additional observations on some fine structures of Demodex folliculomm under SEM were presented in this paper, including supracoxal spines, hypostome, palpal claws, male and female podosomal setae, leg claw-basal spur, femoral spur, etc. The supracoxal spines were rivet-shaped and the hypostome was pearshaped. The claws on the tarsal coxa of the pulpus meander to the ventral side instead of meandering to the dorsal side. Based on these structural characteristics, it was inferred that podosomal seta may be a sensilla and claw-basal spur as well as femoral spur can protect mites against being expelled from follicules (Figs.A-M).
