Subspecies
Closely related to Streak-necked Flycatcher (Mionectes striaticollis). Populations vary along two north-south clines, one from Costa Rica south to western Ecuador and the other following eastern base of mountains from north-eastern Venezuela and Trinidad south to Bolivia. Described subspecies improvisus (northern Cauca Valley) merged with hederaceus, as intermediate within western cline; pallidus (eastern Andes of Colombia in Magdalena and northern Meta) and meridae (north-western Venezuela and adjacent north-eastern Colombia) are indistinct, intermediate forms within eastern cline, both treated as synonyms of venezuelensis.
