Two new genera and one new assignment of eriophyoid mites (Acari: Eriophyoidea) from Thailand

Three eriophyoid mites (two new genera and three new combinations) from Thailand are redescribed herein. They are: Phutsona gen. nov., Ph. ervatamiae (Chandrapatya, 1991) comb. nov. on Gardenia jasminoides J. Ellis (Rubiaceae) [the original host plant, Ervatamia coronaria, was an error in identification]; Lipacarus gen. nov., L. eugeniae (Boczek, 1992) comb. nov. on Syzygium samarangense (Blume) Merr. and L.M. Perry (Myrtaceae); Pentacecidophyes litchi (Boczek, 1996) comb. nov. on Litchi chinensis Sonn. (Sapindaceae). Pentacecidophyes is reassigned to Eriophyidae, Phyllocoptinae, Phyllocoptini. Pentacecidophyes xinglongis Xue, Cheng and Hong, 2011 is considered as a junior synonym of Pe. litchi.
