Olive-striped Flycatcher is split into two species, based vocal differences (Boesman 2016e) and genetic evidence that the current arrangement of Olive-striped Flycatcher is paraphyletic (Harvey et al. 2020). As a result, the monotypic group Olive-striped Flycatcher (Olive-streaked) Mionectes olivaceus olivaceus becomes Olive-streaked Flycatcher Mionectes olivaceus; and the polytypic group Olive-striped Flycatcher (Olive-striped) Mionectes olivaceus [galbinus Group] becomes Olive-striped Flycatcher Mionectes galbinus, with subspecies hederaceus, galbinus, venezuelensis, and fasciaticollis.
