DIAGNOSIS. Adult female oval to broadly oval, membranous. Anal lobes moderately developed. Antennae 7 or 8 segmented. Legs well developed, slender. Translucent pores present in moderate numbers on hind coxa, femur and tibia. Cerarii numbering 17 pairs. Anal lobe cerarii each with 2 enlarged conical setae, plus about 4 or 5 auxiliary setae and a group of trilocular pores, all situated on a sclerotized area, a little larger than anal ring. Anterior cerarii each with 2 conical setae, except each anterior mesothoracic pair with 3, and those on head with 3 or 4. Circulus well developed, notched at each side and divided by an intersegmental line. Ostioles well developed, prominent. Dorsal surface with long slender setae, accompanied by some short setae; ventral surface with normal slender setae. Ventral multilocular disc pores present around vulva and medially in more or less single rows on posterior edges of abdominal segments IV–VII; also usually in single rows on anterior edges of abdominal segments VI and VII; a few also scattered medially on thorax. Dorsal and ventral trilocular pores evenly dispersed. Dorsal and ventral discoidal pores minute, sparsely dispersed and absent from next to eyes. Dorsal oral rim ducts, when present, few, usually with a pair located behind each frontal cerarius and a submedial pair situated on metathorax. Ventral oral rim ducts, often with a discoidal pore next to rim, present on margins of thorax, often extending to spiracles, and on abdominal segments I and II. Dorsal oral collar ducts, often with an obscure rim and with 1 or 2 discoidal pores next to orifice, usually present on margins of head and abdominal segment VII; ventral oral collar ducts normally of 3 sizes: large type, each often with a discoidal pore next to orifice and sometimes with a narrow obscure rim, distributed in marginal groups on abdominal segments and sparingly around margins of thorax and head, usually in a single marginal row at most; a small duct, each narrower than a trilocular pore, usually present medially on abdominal segments, and a minute duct present across middle of abdominal segments plus a few scattered on medial area of thorax.

DISTRIBUTION. Afrotropical, Australasian, Neotropical, Oriental, Palaearctic: Afghanistan, China, Iran, Israel, Japan and Spain. This mealybug is known from 41 plant families (Ben-Dov et al., 2012).

COMMENTS. P. c r yp t us was listed in the checklist of Kozár et al. (1996), but it has not been observed by the author in nature and there are no specimens in HMIM.
