Previously placed in Seicercus; see Phylloscopidae. Hitherto treated as conspecific with P. grammiceps, but differs in its plain grey upperparts, without olive wash (1); darkish-grey vs white rump (3); and, although song very similar, call a short single nasal note vs a short high rattle or a buzzy high overslur (for length and pitch differences, total 4)#R. Monotypic.
