This is the first record of Evandromyia (Aldamyia) sericea in southeastern Brazil and report the southernmost record ever of this species in the world. Specimens were collected in the Reserva Biológica de Duas Bocas, municipality of Cariacica, state of the Espírito Santo. Captures of the sand flies were carried out monthly from April to June 2008 during four consecutives nights using two automatic light traps (CDC model) and a modified Shannon trap for each night. The finding of this species corroborates the hypothesis of the phylogeographical proximity of the Amazon Rainforest and the Atlantic Forest.
