The Perinereis nuntia species group is revised on the basis of material from worldwide localities. Twenty available names are reduced to 12 recognised species, including two new species: Perinereis akuna (from southern Australia) and P. namibia (from southern Africa). Specimens from Indonesia and from Juan Fernandez Islands cannot be identified and may represent two additional undescribed species. Perinereis broomensis Hartmann-Schroder, 1979 is synonymised with P. nuntia (Savigny, 1818) for the first time. A key to species is provided.
