During a field expedition in 2020, we recorded specimens of an invasive platy fish, Xiphophorus maculatus, in the state of Maranhão, Brazil. This new occurrence, in the Municipality of São Luis, is only the second time that this non-native species has been found in northeastern Brazil. We provide an updated list of all invasive species recorded from the island of São Luís, highlighting the negative impacts they may confer for the native biodiversity.
