The objective of this study is to report seven decapod crustacean species for the first time from Sergipe state, northeastern Brazil. The specimens were sampled from January 2012 to June 2015, on continental shelf and estuaries. Alpheus buckupi, Synalpheus ul, Lysmata bahia, L. cf. intermedia, Paguristes tortugae, Macrocoeloma laevigatum and Pilumnoides coelhoi are reported. This study records fill gaps in the geographical distribution of these decapods that have previous records for adjacent areas.
