A. B. Meyer, 1874,
Kordo, Biak Island.
One of several taxa recently split from R. rufiventris#R (which see). Differs from all other taxa in that complex by various characters in unique combination: white throat; plain black breastband; white belly to vent; blackish upperparts; and rather short, notably graduated tail. Differs in particular from geographically closest representative of rufiventris complex, R. isura race gularis, in its black vs grey breastband (3); white vs pale tan belly to vent (2); darker upperparts (1); much shorter tail (at least 2); and rather divergent song (2)#R. Differs from its morphologically closest representative, R. obiensis, in characters given under that species. Monotypic.
