Three new cecidogenous species of Palaeomystella Fletcher (Lepidoptera, Momphidae) from the Brazilian Atlantic Rain Forest.

Three new cecidogenous species of Palaeomystella Fletcher (Lepidoptera, Momphidae) from the Brazilian Atlantic Rain Forest are described. Larvae of P. fernandesi Moreira & Becker, sp. n., P. rosaemariae Moreira & Becker, sp. n. and P. tavaresi Becker & Moreira, sp. n. induce galls, respectively, on Tibouchina sellowiana (Cham.) Cogn., T. asperior (Cham.) Cogn. and T. fissinervia (Schrank & Mart. ex DC.) Cogn. (Melastomataceae). Adults, immature stages and galls are illustrated, and data on life history and a preliminary analysis of mitochondrial DNA sequences, including related species, are also provided.
