The Raspy-voiced gray antbird was described as a new species in 2026. The male type specimen is dark grey overall with a white interscapular patch, and its loudsong is distinctive.
The male type specimen is dark grey overall, with a white patch between the shoulders. Its plumage is darker than C. cinerascens, though the description notes some overlap.
Its loudsong consists of disyllabic phrases made only of raspy notes. The authors report this vocal pattern as a practical feature distinguishing its song from those of close relatives.
