We performed a comparative study of the specimens from the Naineris setosa complex from the Pacific and the Atlantic Oceans and re-described the syntype of N. setosa, including the selection of the lectotype. Molecular phylogenetic and species delimitation analyses based on two mitochondrial (COI and 16S) and one nuclear (28S) marker revealed the presence of three species. One clade with wide Amphi-Atlantic distribution was attributed as Naineris setosa s. str. The second Atlantic clade restricted to Southern and Southeastern Brazil was described as a new species, Naineris lanai sp. n. The third clade, reported from the Northwestern Pacific, was identified as a new species but was not formally described due to the presence of only juvenile-sized worms in the studied material. Detailed morphological descriptions of several diagnostic characters in the Naineris setosa complex are provided
