New genera and species of gall midges (Diptera, Cecidomyiidae) associated with Guarea macrophylla (Meliaceae)

Abstract

Three distinct leaf galls are recorded on Guarea macrophylla (Meliaceae). The galling species were identified as Neolasioptera sp., Guareamyia purpura gen. nov. and sp. nov.; Sphaeramyia flava gen. nov. and sp.nov. The new genera and species are described and illustrated based on material collected at restinga areas in Bertioga (São Paulo, Brazil).
