Remarks
- Systematics: Lepidosaphes esakii is close to L. duponti, but the median lobes of the latter are wider and closer together than in the former. The inner lobule of the second lobes of L. duponti is much wider than that of L. esakii (Beardsley, 1966).
- Structure: Adult female 1.75 mm long, tending to be broadly oval, widest at mesothorax; lateral lobes of abdominal segments only moderately developed; head and pygidium rounded (Williams & Watson, 1988).
- General Remarks: Detailed descriptions and illustrations by Takahashi (1939b), Beardsley (1966) and Williams & Watson (1988).
