G. R. Gray, 1870,
Vanua Lava, Banks Islands.
Hitherto treated as conspecific with R. verreauxi, R. layardi and R. rufilateralis, but differs from first in its lack of wingbars (2); buffy-whitish vs smoky-ochreish belly and vent (2); less densely patterned breast with untidier line separating it from white throat (2); longer and broader-looking bill and longer wing (effect size for male bill 3.11, score 2), although tail generally shorter (ns); and faster song, with more but shorter notes (2+2=4). Differs from R. layardi in faster song (4) and in characters shared with R. verreauxi, namely blade-shaped scalloping vs long streaks on breast (2); pattern on undertail vague (shading mid-brown to whitish edges and tips) vs darker, more extensive brown with sharply defined white tips (3); and fuller and longer white lores and supercilium (2); plus much less rufous upperparts than R. l. erythronota (ns). See also R. rufilateralis. Monotypic.
