Hitherto treated as conspecific with N. squamipila (which see), along with N. hypogramma and N. forbesi. It is distinct from N. forbesi by virtue of its having underparts reddish-brown with vestigial (pale rufous and cinnamon) barring vs plain reddish-brown breast with strong equal rufous and white barring on belly (3); tarsi sparsely feathered vs densely feathered to toes (3); darker rufous upperparts (1); less white spotting on wing-coverts (ns[1]); slightly longer tail (effect size 1.65, score 1); and different voice, reportedly being similar to that of N. squamipila (which see) vs “monotonic, double-noted ku-kuk...; also a single frog-like gurr”#R (3). For differences from N. hypogramma and N. squamipila, see those species. Monotypic.
