Four taxa of terebellines with problematic taxonomic histories are redescribed. One is a new species that has been misidentified for the last 37 years and one is allocated to a different genus from that to which it was previously assigned. Pista corrientis McIntosh, 1885 was described from Argentina and has been reported from several localities along the Brazilian coast. Examination of the holotype of P. corrientis revealed that the Brazilian specimens belong to a separate species, herein described as P. nonatoi sp. nov., and a redescription of the holotype of P. corrientis is provided. Pista sombreriana (McIntosh, 1885) was considered indeterminable due to the poor condition of the holotype. Our examination of the holotype showed that although it is poorly preserved most taxonomic characters are visible. The morphology of the lobes on anterior segments, especially those of segments 3–4, is closer to Lanicides than to Pista but considering that Lanicides is also poorly defined we redescribe P. sombreriana under its original designation. Finally, Eupolymnia turgidula (Ehlers, 1887) has been considered as a junior synonym of E. crassicornis (Schmarda, 1861) but a recent study resurrected it as a valid species of Terebella, which was the original generic designation. According to our examination of the holotype, E. turgidula does belong to Eupolymnia, but it is uncertain as to whether it is a valid species or a synonym of either E. crassicornis or E. magnifica (Webster, 1884).
