The four subspecies of what is now the olive-striped flycatcher (Mionnectes galbinus) were previously treated as subspecies of what is now the olive-streaked flycatcher. (Confusingly, the original unsplit species was called the olive-striped flycatcher but bore the present olive-streaked flycatcher's binomial Mionectes olivaceus.) Based primarily on vocal differences the species were separated by taxonomic systems beginning in 2016, leaving the olive-streaked flycatcher as a monotypic species. However, as of late 2024, the North American and South American Classification Committees of the American Ornithological Society have not agreed to the split. They retain the olive-striped flycatcher/Mionectes olivaceus names.
