Previously treated as conspecific with M. inquieta, and recent molecular evidence tends to support this option#R#R; however, application of Tobias criteria to differences registered in the literature suggest species status may yet be appropriate (and therefore provisionally retained here), involving considerably smaller size (effect size for male wing using largest samples in published data#R –6.78, score 3); “much darker upperparts” in male#R (1); bill width not proportionately reduced (on published data#R), thus appearing broader-based#R (allow 1); rictal bristles proportionately longer (two-thirds vs less than half the length of bill) and thicker#R (allow 1); and a much more frequently delivered “tuuiii” call, with a second call contextually more restricted#R (allow 1); all these characters (even the wing mensural data, which may not reflect the situation where the taxa most closely approach each other) are tentatively scored and require validation. Monotypic.
