Until recently was considered conspecific with M. momota (also M. aequatorialis), but proposed for species rank#R on basis of “forehead green” (in fact dull pale brown-green vs metallic turquoise) (2) and “crown blue” vs blue with broad black centre) (3), to which can be added no bright turquoise flush on chin and throat (1), paler, more uniformly green underparts with less rufous contrast on breast (ns[1]) and markedly larger black breast streaks (effect size for exposed length vs combined three races of M. lessonii 2.02, score 2).

Distribution:

NE Mexico (E Nuevo León, S Tamaulipas).
