Three new species of Lopesia Rübsaamen (Insecta, Diptera, Cecidomyiidae) from Brazil

Authorship SCIMAGO INSTITUTIONS RANKINGS

Lopesia rondoniensis Proença & Maia sp.nov., Lopesia tonteleae Proença & Maia sp.nov., and Lopesia matogrossensis Proença & Maia sp.nov., three new species of Cecidomyiidae (Insecta: Diptera) that induce fusiform galls on leaves of Swartzia sp. (Fabaceae), conical galls on leaves of Tontelea sp. (Celastraceae), and lenticular galls on Protium sp. (Burseraceae), respectively, are described and illustrated based on material from Rondônia and Mato Grosso states, Brazil.

Keywords:
Galling insect; gall midge; Amazonian rainforest; Cerrado; taxonomy
