Composetia Hartmann-Schröder, 1985 (Nereididae de Blainville, 1818), to which 51 species with broadly heterogeneous characteristics were previously assigned, is reviewed based upon the examination of the type material of the type species, C. costae (Grube, 1840), and seven other species. According to our designation of the lectotype of C. costae, a generic definition of Composetia is established, and taxonomic issues about C. costae are addressed. The current taxonomic status of several species similar to or previously synonymised with C. costae is re-evaluated. Based on the redefinition of Composetia, the taxonomic status of all species previously regarded as Composetia is reassessed. Consequently, three species are moved to two newly established genera based on their type material: Parasetia gen. nov., comprising the single species P. irritabilis (Webster, 1879) comb. nov.; and Potamonereis gen. nov., embracing P. kumensis (Sato, 2020) comb. nov. and P. tokashikiensis (Sato, 2020) comb. nov. Additionally, one species is redescribed and transferred to Leonnates, L. microcephala (Grube, 1878) comb. nov. Ten species currently remain in Composetia, and two of them, C. brasiliensis (McIntosh, 1885) and C. versipedata (Ehlers, 1887), are redescribed. Nereis articulata Ehlers, 1887, previously considered a member of Composetia, has a doubtful identity requiring further investigation. Although the generic placement of many of the remaining species is uncertain, we present our tentative re-evaluations for each of them. Keys are included for identifying all genera similar to Composetia, and for identifying all species within Composetia and Potamonereis gen. nov.
