Sometimes treated as conspecific with M. barbatus#R, but appears to have a distinctive, very short, high main call, “spik!”, which, if present in M. barbatus, is evidently not a main call#R; further research needed. Race aureatus thought by some perhaps to be a separate species, but call identical to that of nominate. Two subspecies recognized.

Subspecies and Distribution
  • M. s. sulphureipygius (P. L. Sclater, 1857) – SE Mexico (from S Veracruz and N Oaxaca) S on Caribbean slope to NW Honduras.
  • M. s. aureatus Bangs, 1908 – NE Honduras S on Caribbean slope, and locally on Pacific slope in Costa Rica and Panama, to Pacific lowlands of W Colombia and W Ecuador (W Loja); recently recorded in NW Peru (Tumbes)#R.
