Validation characters: Without dorsal oral-rim tubular duct near frontal cerarius; oral-rim tubular ducts scattered over dorsum; dorsal setae about same length or shorter than conical cerarian setae (except on segment VIII where long); translucent pores on hind femur and tibia; without discoidals near eye; without clusters of ventral oral-collar tubular ducts laterad of front or middle legs.

Comparison: Pseudococcus calceolariae can be distinguished from other species in the genus by lacking an oral-rim tubular duct near the frontal cerarius and by having short dorsal setae.
