Sumario:A new shallow-water species of the alpheid shrimp genus Alpheus Fabricius, 1798 is described based on five specimens from Maceió, Alagoas, northeastern Brazil. Alpheus schubarti sp. nov., belongs to the A. paracrinitus Miers, 1881 species complex and is most closely related to the eastern Pacific A. rostratus Kim & Abele, 1988, from which it can be separated by several morphological differences and the colour pattern of the major and minor chelae.
