#R, Montevideo and Buenos Aires; error = probably São Paulo, Brazil.
Sister-species to L. squamatus; formerly regarded as conspecific, but the two populations on opposite sides of R Paraíba do Sul, in N São Paulo, differ significantly in three plumage characters (crown pattern, and coloration of back and of tail) and measurements; the depression associated with this river represents a boundary for several other well-marked taxa. Monotypic.
S Brazil from NE São Paulo (S bank of R Paraíba do Sul) S to S Rio Grande do Sul, also adjacent SE Paraguay (Alto Paraná), NE Argentina (Misiones, NE Corrientes) and extreme NE Uruguay.
