Abstract
Parlatoria tsujii sp. nov. (Hemiptera: Diaspididae) is described and illustrated from 10 adult female specimens collected in Okinawa Island. It resembles P. camelliae and P. mytilaspiformis, differing from P. camelliae in the pygidial plates between the lobes having 2 or 3 tines and from P. mytilaspiformis in having submedian dorsal microducts.
