Common name: Cryptic or citriculus mealybug

Field Characters: Body oval; slightly rounded in lateral view; pale yellow or greenish yellow; body contents crushed are greenish yellow; mealy wax covering body, usually thick enough to hide body color except on intersegmental lines; without longitudinal lines on dorsum; ovisac ventral only; with 17 lateral wax filaments, becoming progressively longer posteriorly, anterior pair about 1/4 width of body, straight or slightly curved distally, thick, posterior pair longest, varying from 3/4 to 1 time length of body.

Validation characters: Dorsal oral rims greatly reduced in number, varying from none to as many as 8; dorsal setae long, almost as long as ventral setae; translucent pores on hind coxa, femur, and tibia; dorsal oral-collar tubular ducts nearly always present near cerarii, sometimes scattered elsewhere; ventral oral-collar tubular ducts few, forming narrow band on thorax and head; without discoidal near eye.

Comparison: Pseudococcus cryptus is an unusual member of the genus Pseudococcus by possessing such a small number of dorsal oral-rim tubular ducts; in some cases dorsal oral rims are entirely absent or there may be up to 8 on the entire surface. This species is very similar to P. aurantiacus, but differs by having more than 1 vental oral rim near each spiracle, a few ventral oral rims on the anterior abdominal segments, and a narrow band of oral collars on the margin of the thorax. P. aurantiacus has 1 ventral oral rim near each spiracle, no ventral oral rims on the anterior abdominal segments, and a broad band of oral collars on the margin of the thorax.
