One of several taxa recently split from R. rufiventris#R (see that species). Differs from all other taxa in that complex by various characters in unique combination: throat boldly white-streaked like breast; buffy-white belly to vent; large white tail tips; song#R. Differs in particular from geographically closest representative of complex, R. rufiventris, in its white-streaked grey vs all-white throat (3); white-streaked grey vs diffuse white-on-grey breast (3); much paler belly to vent (2); and notably divergent song (4). From morphologically closest representative, R. cinerea, differs in its white-streaked grey vs all-white throat (3); buffy-white vs white belly to vent (1); large vs at best vestigial white tail tips (3). Monotypic.
Roti (off SW Timor), in Lesser Sundas.
