• Systematics: Fletcher (1919) considered Chionaspis manni (=Pseudaulacaspis manni) to be synonymous with Chionaspis prunicola var. theae (=P. prunicola theae).
• Structure: Female scale irregular, broadly dilated posteriorly, usually curved. Exuviae at anterior extremity projecting beyond margin of scale, larval exuviae fulvous; nymphal exuviae castaneous, more or less concealed beneath a thin coating of greyish secretion, pygidial margin with prominent median lobes, 2.3-2.8 mm long, 1.10-2.15 mm wide. Adult female narrowest in front, broadest across abdominal area. In the early adult female, the pygidium occupies fully one third of the whole area, later, the thoracic segments increase in size. Pygidium rounded or obtusely pointed. Median lobes large, prominent, their bases confluent, the apices rounded, divergent, occupying a shallow median cleft, projecting far beyond the margin. 2nd lobes duplex, prominent, narrow (Green & Mann, 1907).
