New Quercus-Infesting Bariella and Glyptacus Species and Redescription of Aceria cerrigemmarum (Nalepa) from Hungary (Acari: Prostigmata: Eriophyoidea)

摘要

Bariella bakonyense n. sp. and Glyptacus matrensis n. sp. were collected, described and illustrated from Quercus cerris and Quercus petraea, respectively. Both eriophyid mite species are leaf vagrant. Aceria cerrigemmarum was collected, redescribed and illustrated from Quercus cerris. This gall mite species causes bud proliferation and death of buds in several Hungarian forests. Two other eriophyid mite records are presented.
