The Yellow-throated Antwren is endemic to far northwestern Amazonia, where it is confined to extreme southwest Venezuela, far-eastern Colombia, and northwest Brazil, and is found in a variety of forest types, all of them growing on white-sand soils. It primarily occurs in the true lowlands, below 500 m, but locally the species ascends to approximately 1100 m on some tepuis. This antwren’s plumage broadly recalls that of the congeneric Sclater’s Antwren (Myrmotherula sclateri), which is found only south of the Amazon, where it appears to be the present species’ ecological counterpart. Very little has been published concerning the Yellow-throated Antwren’s behavior, although it seems to be a constant member of mixed-species foraging flocks in the canopy and subcanopy throughout its range, and these bands frequently also contain Pygmy Antwren (Myrmotherula brachyura).
