Hitherto treated as conspecific with P. euophrys, but differs from geographically and morphologically closest race P. e. atriceps by its greyer crown, nape, superciliary, throat and lower underparts (2); light brown vs rufous-brown upperparts (1); larger size (although based on very small sample#R) (allow 1); and distinctive song, involving an asynchronous duet with a lower maximum frequency (2), different note shapes (ns[1]) and asynchronous delivery (reflected by pace, score 3)#R. Monotypic.
