Systematics: P. papayae is close to P. brideliae, but different in the larger median lobes, which are wider than the lobules of the 2nd lobes. Related to P. dilatata (=P. cockerelli), but the scale and body being much narrower. P. papayae can be differentiated from Chionaspis sozanica by the median lobes being further apart, with a pair of setae between them (Takahashi, 1942b).
Structure: Female scale elongate, slightly widened posteriorly, white, with pale yellowish brown exuviae, about 2.7 mm long. Adult female body narrow. Pygidium tapering with anus nearer to the base than the apex. Median lobes rather large, stout, much longer than wide, rounded apically, distinctly serrate, slightly diverging, inner lobules rounded, a little longer than wide, not notched, much narrower than the median lobes (Takahashi, 1942b). There may be two forms of this species as to the shape of the median lobes: in one form the median lobes are somewhat produced, their apices scarcely or very slightly exceeding the 2nd lobes, while in the other, the median lobes are more or less retracted into the pygidium and are distinctly exceeded by the 2nd lobes (Takagi, 1960a).
General Remarks: Detailed descriptions and illustrations by Takahashi (1942b) and Takagi (1960a).
