Once considered a race of M. nigrocristata. Hitherto treated as conspecific with M. luteoviridis and M. striaticeps, but differs from former in same characters as M. striaticeps (which see), and from latter in its bolder, longer supercilium (1); black vs olive-grey lores and frons to mid-crown (3); shorter wing (allow 1); much higher-pitched notes in song (only down to c. 3.5–4 vs 2.5 kHz; score 2), with pace slightly faster and song phrases shorter, and a repetitive pattern in duet twittering (1)#R. Monotypic.
