Abstract: 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).
