Remarks

• Systematics: Because Chionaspis theae Maskell 1891a (=Pinnaspis theae) was considered synonymous with Chionaspis prunicola theae Maskell 1896b (=Pseudaulacaspis prunicola theae according to Borchsenius (1966), citations of either name could be incorrect and refer to the other species.
• Structure: Female scale normally brown, but at times white. Adult female with median pygidial lobes very small, at times shorter than the 2nd lobes, slightly separated, their outer margins variously notched; basal sclerosis small, but distinct. 2nd lobes unusually strongly developed, the mesal lobe expanding toward the apex and apically somewhat hatchet-shaped, the outer lobule but slightly smaller, apically rounded. 3rd lobe also well developed (Ferris & Rao, 1947).
• Biology: Male scales tend to arrange themselves in great number on host leaves, close together and all pointing in the same direction (Ferris & Rao, 1937).
• Economic Importance: Miller & Davidson (1990) list this insect as a pest.
• General Remarks: Detailed description and illustration by Ferris & Rao (1947).
