Abstract Three new species of Asphondylia are described from Minas Gerais (Brazil): Asphondylia ingaiensis, A. rufae and A. zeyheriae. They induce galls on Moquiniastrum barrosoae (Asteraceae), Bauhinia rufa (Fabaceae), and Zeyheria montana (Bignoniaceae), respectively, all native to Brazil, being the last endemic. Illustrations of relevant morphological characters are provided. The new species are compared with congeneric Neotropical species. Types are deposited in the Museu Nacional, Entomological Collection.

Abstract Three new species, Bruggmanniella miconiae sp. nov., B. notatae sp. nov. and B. sideroxyli sp. nov., are described and illustrated. The new species are associated, respectively, with Miconia theaezans (Bonpl.) Cogn (Melastomataceae), Ocotea notata (Nees and Mart.) Mez (Lauraceae) and Sideroxylon obtusifolium (Roem. and Schult.) T. D. Penn. (Sapotaceae), respectively. The first one was collected in Dores do Indaiá city, Minas Gerais, Brazil; and the two others were collected in Mangaratiba city, Rio de Janeiro, Brazil. An illustrated key to the Bruggmanniella species is provided.

Abstract Lopesia indaiensis (Diptera, Cecidomyiidae), a new species of gall midge found causing galls on Andira fraxinifolia (Fabaceae), an endemic plant species in Brazil, is described based on larva, pupa, male and female. L. indaiensis galls were collected in Dores do Indaiá, State of Minas Gerais, Southeastern Brazil. Larvae were removed from the galls and pupae and adults were obtained by rearing. The specimens were mounted on slides and the most important morphological characters were illustrated. The new species was compared to the other species of Lopesia.
