Summary: Ants are considered an important group of invertebrates in terrestrial ecosystems, where they participate in important ecological processes between animals and plants, and they are considered good indicators of environmental impacts as well. Although the diversity of ants in the Amazon biome is already relatively well known, the ant fauna in the state of Acre, Brazil is still poorly known. The aim of this study was to carry out a survey of ants in a forest remnant located in the municipality of Plácido de Castro, Acre, using pitfall traps. Thirty-six species of ants were collected from six subfamilies and 18 genera. From the species confirmed, 11 (Cephalotes serraticeps, Gnamptogenys moelleri, Gnamptogenys triangularis, Neoponera apicalis, Neoponera commutata, Neoponera verenae, Mayaponera constricta, Megalomyrmex emeryi, Pachycondyla impressa, Pheidole araneoides and Odontomachus caelatus) are first records for Acre state, increasing our knowledge of the epigaeic ants that occur in this region of the Amazon. As formigas são consideradas um significante grupo de invertebrados nos ecossistemas terrestres, participando de importantes processos ecológicos entre animais e plantas, além de serem consideradas como bons indicadores de impactos ambientais. Apesar de a diversidade de formigas no bioma Amazônico já ser relativamente bem conhecida, a fauna de formigas do estado do Acre ainda é incipientemente estudada. O objetivo deste estudo foi realizar um levantamento de formigas em um remanescente florestal localizado no município de Plácido de Castro - Acre, utilizando armadilhas do tipo "pitfall trap". Foram coletadas 36 espécies de formigas, pertencentes a seis subfamílias e 18 gêneros. Das espécies confirmadas, 11 (Cephalotes serraticeps, Gnamptogenys moelleri, Gnamptogenys triangularis, Neoponera apicalis, Neoponera commutata, Neoponera verenae, Mayaponera constricta, Megalomyrmex emeryi, Pachycondyla impressa, Pheidole araneoides e Odontomachus caelatus) representam primeiros registros para o estado do Acre, aumentando o conhecimento acerca das formigas epigeias que ocorrem nesta região da Amazônia.
