Remarks

• Systematics: Anisococcus quercus has been confused with Pseudococcus agrifoliae Essig, Dactylopius crawii Coquillett and Pseudococcus quercicolus Ferris, in Ferris (1918b, 1919c). These species have been variously synonymized, but are currently all regarded as being recognizable, distinct species (Ferris, 1950a, 1953; McKenzie, 1967).
• Structure: See color photograph of the adult female in McKenzie (1967).
• Biology: Occurring on the small twigs or in cracks in the bark of the host plant.
• General Remarks: Good description and illustration of the adult female given by Ferris (1950b) and by McKenzie (1967).
