On Cerodontha (Diptera: Agromyzidae) from Brazil: new species and new records

ABSTRACT There are few literature publications on the species of Cerodontha Rondani, 1861 that occur in Brazil. This contrasts with the situation in the Nearctic region and Europe, where the genus is well-studied. We analyzed specimens of Cerodontha from two important collections in Brazil: Instituto Nacional de Pesquisas da Amazônia and Museu Nacional, Universidade Federal do Rio de Janeiro. As a result, we found and describe two new species: Cerodontha (Poemyza) teresopoliensis sp. nov. and Cerodontha (Poemyza) rafaelii sp. nov., that both can be recognized for some specific character, as the darker body coloration and form of the male genitalia. We also provide new records and additional characters to diagnosis for the Cerodontha (Butomomyza) orcina Spencer, 1973 and Cerodontha (Butomomyza) obscurata Martinez, 1992. The descriptions are illustrated with images of the external morphology of the adult and male genitalia. A key to the Brazilian species of the subgenera Butomomyza and Poemyza are also provided.
