The Spot-backed Antwren occupies a relatively wide range in northwest Amazonia, where it is found from southern Venezuela and eastern Colombia south and east as far as the north bank of the Amazon in northwest Pará, Brazil. Given the typical views that most observers will achieve of this species, the white edges to the back feathers, from which this species acquires its vernacular name, will probably be invisible! However, over the majority of this species’ range it is the only Herpsilochmus antwren, making identification reasonably straightforward, even when observing this canopy inhabitant from ground level. Only in southwest Venezuela is there any potential overlap with another congeneric, the larger-bodied Roraiman Antwren (Herpsilochmus roraimae), but the two species are probably almost completely segregated altitudinally, with Spot-backed Antwren in the lowlands, and their songs are rather different.
