Six localities of São Tomé das Letras (MG, Brazil) were investigated from September, 2011 to June, 2012. The local vegetation was examined in search of insect galls. A total of 152 morphotypes of insect galls were found on 94 plant species (74 genera and 37 families). Fabaceae, Melastomataceae, Myrtaceae, and Asteraceae were the plant families with the greatest richness of galls, with 20, 18, 17, and 12 gall morphotypes, respectively. The super host genera were Copaifera L. (Fabaceae), Myrcia DC. ex. Guill. (Myrtaceae), and Miconia Ruiz & Pav. (Melastomataceae), with 10, 10 and 09 gall morphotypes, respectively. The super host species was Copaifera cf.langsdorfii Desf. (Fabaceae), with 10 gall morphotypes. Galls were found on leaves, stems, buds, and aerial roots. Leaves were the most galled plant organ, followed by stems, and buds. The inducers belong to Diptera, Lepidoptera, Hemiptera, Thysanoptera, Coleoptera, and Hymenoptera, being Cecidomyiidae (Diptera) the most frequent and diversified gallers. The associated fauna included parasitoids (Hymenoptera), inquilines (Lepidoptera and Thysanoptera), successors (Formicidae, Hymenoptera), and predators (pseudoscorpion), obtained from 18, 02, 02, and 01 gall morphotype, respectively. Ten galling species are recorded for the first time in São Tomé das Letras (MG). The present study indicates São Tomé das Letras (MG) as an area of great richness of insect galls.
