Lesson

, 1829,

Santa Catarina, Brazil

.

Previously treated as a race of O. vetula or of an expanded O. motmot or, more recently, of O. guttata. Differs from O. guttata in much less chestnut-rufous undertail with more grey-black at base of feathers (3); more rufous-toned rump (2); and brown-shaded vs blackish crown (2); also some vocal differences. Differs from O. araucuan in its dull brown crown, almost continuous with rest of upperparts vs dull rufous crown and rear head-sides (2); absence of arrowhead-shaped, pale-tipped feathers on rear crown, neck-sides and upper throat (3); buffy-brown vs white to whitish belly (3); chestnut vs ochraceous vent (ns[2]). Birds of SE Mato Grosso have been ascribed race remota, but apparently very similar or identical to those in rest of range. Monotypic.

Distribution:

SE Brazil (SE Mato Grosso do Sul and S São Paulo to Rio Grande do Sul); perhaps SE Paraguay.
