Systematics: P. celtis is close to P. cockerelli, but differs by the presence of gland tubercles on the mesothorax and by the fewer dorsal macroducts (there are 4 pairs in P. celtis and 5 pairs in P. cockerelli) in the 2nd stage female (Tang, 1986).
Structure: Female scale elongate, straight or curved, convex, white in color. 1st exuviae pale yellow with orange yellow caudal end; 2nd exuviae golden yellow, thinly covered with a white waxy secretion. Ventral scale partly developed, 1.5 mm long, 0.9 mm wide. Male scale small, elongate tricarinate; exuviae pale, 0.9 mm long (Kuwana, 1928). Adult female body widest across 1st abdominal segment. Median lobes comparatively very large, with a pair of setae between them, the basal zygosis not protruding anteriorly. 2nd lobes very small, the outer lobule at times almost obsolete. 3rd lobes represented by low processes (Takagi, 1961).
