Cryptococcus fagisuga Lindinger, 1936 (Cryptococcidae: Cryptococcus)

Nomenclatural History

Coccus fagi Baerensprung 1849: 174. Type data: GERMANY: Berlin. Syntypes, female, junior homonym (discovered by Lindin1936b, 444). Replacement name for Coccus fagi Sulzer 1776 Notes: Type material has probably been lost (Williams, 1985h).
Coccus fagi Walker 1852: 1086. Type data: ENGLAND. Lectotype, female, by subsequent designation (Willia1985h,353-356). synonym and homonym (discovered by Lindin1936, 444). Notes: Coccus fagi Walker is a junior homonym of Coccus fagi Sulzer 1776 and Coccus fagi Baerensprung 1849.
Pseudococcus fagi (Baerensprung, 1849); Douglas 1886c: 152. change of combination
Cryptococcus fagi (Baerensprung, 1849); Douglas 1890a: 155. change of combination
Eriococcus fagi (Baerensprung, 1849); Perrier 1926: 122. change of combination
Cryptococcus fagisuga Lindinger 1936b: 444. replacement name Replacement name for Coccus fagi Baerensprung 1849
Kermes fagi (Baerensprung, 1849); Lindinger 1957: 549. change of combination Notes: Lindinger (1957) meant to reiterate the placement of fagi in Cryptococcus and he cites Guérin (1818) as the creator of the Kermes fagi combination. The date of this is probably wrong, and no publication by Guérin mentioning the combination can be found. Therefore, at least for the time being, this combination will be listed as by Lindinger (1957) even though it is not what he intended.

Remarks

Systematics: This species was first described as Coccus fagi Baerensprung (1849). The next description was as Coccus fagi Walker (1852). C. fagi Baerensprung is the junior primary homonym of C. fagi Sulzer (1776). C. fagi Walker is a synonym of C. fagi Baerensprung and a junior primary homonym of C. fagi Sulzer. The next three names Pseudococcus fagi Douglas (1886c), Cryptococcus fagi Douglas (1890) and Eriococcus fagi Perrier (1926) are change of combinations. The last and final change is to Cryptococcus fagisuga Lindinger (1936) who realized the homonymy of the species (Miller & Miller, 1993). C. fagisuga is part of a clade that includes one other Palearctic species (P. fraxini), one Nearctic species (C. williamsi), and two species endemic to New Zealand (C. nudatus and M. totarae). Since this clade is nested within a larger "Gondwanan" clade consisting of species from Australia and New Zealand, it appears to have originated in New Zealand and to have somehow spread to the North Temperate Zone at an ancient date. (Gwiazdowski et al., 2006)
Structure: Adult female body is nearly hemispherical, bright yellow and covered with a filamentous white sac (Miller & Miller, 1993). Slide-mounted adult female with: antennae 1- to 3-segmented; anal ring with 4 setae; 6 or 8 setae surrounding anal ring (Kosztarab & Kozár, 1988; Miller & Miller, 1993); anal ring with small pores; multiloculars absent from dorsum; macrotubular ducts of 2 sizes (Miller & Miller, 1993).
Biology: The general pattern of life cycle is as follows. Yellow eggs are laid in the spring or early summer within the ovisac. Eggs hatch in late summer and early fall. Crawlers are quite mobile and may move some distance before settling on the bark. The first instar is usually the overwintering stage. During the winter, yellow first instar nymphs change in body form from oval to rotund. Molting occurs during the spring and the short lived apodous second instar is produced. Adult females occur throughout the spring and summer. Males have never been collected (Miller & Miller, 1993). In adult females of C. fagisuga having restricted access of oxygen to apiracles the spiracles are located in deep cavities of scleotised walls which probably contain airr reserves. (Podsiadlo, 2006)
Economic Importance: This scale, together with a fungus, can cause extensive damage to the native beech trees in the northeastern United States (Miller & Miller, 1993). Van Driesche & Japoshvili (2012) found that scale densities were 45.4-fold higher per unit area of bark in Massachusetts on F. grandifolia than in their native range in the country of Georgia on F. orientalis. Also, F. orientalis trees at sample sites in Georgia were 2.9-fold larger in DBH and much healthier that were F. grandifolia trees in Massachusetts. The good condition of beech that were observed during a natural enemy surveys in Georgia might reflect high tree resistance to beech scale in invaded areas. Silvicultural preservation and expansion of the fraction of the American beech population possessing natural resistance to beech bark disease seems to be a more promising tool for restoration of American beech in forest stands than biological control. (Japoshvili, et al., 2015)
General Remarks: Detailed description and illustration by Miller & Miller (1993). Description of first and second instars and adult female by Williams (1985h). Discussion of population dynamics relating to physiological defense reactions of attacked trees by Gora et al. (1996). Detailed description and illustration of first-instar nymph and second-instar female in Miller & Stocks, 2022.
Although Sinclair et al. (1987) state that Cryptococcus fagisuga was found in Ohio, they give no reference and the species has not been recorded in Ohio by any other author known to us. We suspect that the Ohio record is erroneous.
