This study presents the freshwater and estuarine shrimp species that occur in the state of Amapá, in the eastern region of the Brazilian Amazon. The data were obtained through information contained in the Brazilian crustacean collections of the Institute of Scientific and Technological Research of the State of Amapá (IEPA) and the National Institute for Research in the Amazon (INPA) and the detailed examination of the listed specimens. All information contained in the log book and specimen labels were noted for the identification and mapping of occurrence areas in the region. A survey in the literature of the species previously recorded for Amapá was carried out. The diversity of freshwater and estuarine shrimp was composed of 21 species distributed in the following families: Alpheidae (Alpheus nuttingi), Euryrhynchidae (Euryrhynchus amazoniensis, Euryrhynchus burchelli, Euryrhynchus tomasi and Euryrhynchus wrzesniowskii), Lysmatidae (Exhippolysmata oplophoroides), Palaemonidae (Macrobrachium acanthurus, Macrobrachium amazonicum, Macrobrachium brasiliense, Macrobrachium carcinus, Macrobrachium jelskii, Macrobrachium inpa, Macrobrachium olfersii, Macrobrachium surinamicum, Nematopalemon schmitti, Palaemon carteri, Pseudopalaemon amazoniensis, Pseudopalaemon chryseus, Leander tenuicornis), Penaeidae (Xiphopenaeus kroyeri and Sergestidae) (Acetes marinus and Acetes paraguayensis). Alpheus nuttingi and L. tenuicornis were new records for the state of Amapá. This study contributes to the knowledge of the diversity and geographic distribution of decapod crustaceans in Amapá and highlights areas where there are gaps in collection, thus contributing to a better understanding of these invertebrates in the region.
