Review of Andricus species (Hymenoptera, Cynipidae) producing woody tuberous oak galls in México and bordering areas of United States of America

Abstract

A revision of tuberous oak galls induced by Andricus species from Mexico is given. Andricus guanajuatensis Pujade-Villar n. sp., A. santafe Pujade-Villar n. sp. and A. carrilloi Pujade-Villar n. sp. (Hymenoptera: Cynipidae: Cynipini) are described from Mexico. Diagnosis, biology and distribution data of all Andricus species are given. Some morphological characters are discussed, illustrated and compared between related species. A key for all Mexican species and two North American species collected next to Mexico (Andricus wheeleri and A. lebaue Pujade-Villar n. sp.) is included. The gall and host of Andricus dugesi Beutenmüller is described for the first time.
