Antennae stub-like, each 1‒3 segmented. Pro- and mesothoracic legs absent; each hind leg reduced to an oval cluster pore plate. Anal ring bearing 4 setae and small pores and surrounded by 6 or 8 large setae.  Dorsum.Setae conical, scattered. Macrotubular ducts of 1 size, and microtubular ducts present throughout. Multilocular disc-pores absent.  Venter.Setae hair-like. Spiracles heavily sclerotized, each with 3–6 associated quinquelocular disc-pores. Quinquelocular pores present as group in area of anal ring; others present mostly in marginal areas of venter. Macrotubular ducts of 1 size present throughout, and microtubular ducts present along margin. Cruciform pores absent.   Distribution:  Cryptococcus fagisugais a species of Palaearctic origin, now known from 40 countries in the Nearctic and Palaearctic regions ( García Morales et al. 2016). In Iran, it has been recorded from Gilanand Mazandaranprovinces ( Moghaddam 2009).   Host-plants:The scale is oligophagous, having been recorded on host-plants in two genera belonging to the families Fagaceae(  Fagusspp.), and possibly Pinaceae(  Pinus sylvestris) ( García Morales et al. 2016); however, Kosztarab & Kozar (1988)regarded the latter as a very doubtful record. In Iran, it has been found on  Fagus orientalis( Fagaceae) ( Moghaddam 2009).   Economic importance:In association with canker fungi,  Neonectriaspp.(Ascomycota, Nectriaceae);  C. fagisugacauses extensive damage to native beech trees in the northeastern United States( Miller & Miller, 1993a), whereas in its natural range the beech trees are tolerant of the fungi. The scale is of no economic importance in Iran.  Natural enemies:None recorded in Iran.
