The knowledge status of the gall-former cynipids in the Mexican oaks is commented herein. For each of the 157 cited species from 33 oak species, the most important biological and ecological information is included. Andricus championi (Cameron), a species described only from the gall, is considered as 'incertae sedis'. Andricus tumeralis Pujade-Villar nom. nov. is proposed to denominate the species Andricus ashmeadi Dalla Torre & Kieffer for being a homonymy of Andricus ashmeadi Basset. Atrusca dugesi (Mayr) n. comb. (formery in Cynips) and Antron sagata (Kinsey) n. comb. (formery in Sphaeroteras) are proposed. The reasons of these changes are commented as well as the need for further studies on Mexican cynipids.
