Relationships uncertain; on basis of molecular data, earlier thought perhaps to be ancestral to a morphologically variable clade that included X. susurrans, X. guttatus, X. flavigaster and X. lachrymosus, and possibly also X. erythropygius and X. triangularis. Assessment of race notatus complicated by marked individual variation in coloration, and intergradation over seemingly wide area with both nominate and palliatus; birds from R Purus drainage (possibly also R Madeira), in W Brazil, sometimes recognized as race multiguttatus, but intermediate between nominate and palliatus. Race caicarae poorly differentiated (relative to nominate) and with biogeographically unlikely range; doubtfully valid. Original description of race palliatus in issue dated 1855, but not published till 1856#R. Four subspecies recognized.

Subspecies and Distribution
  • X. o. notatus (Eyton, 1852) – drainages of R Apure, upper R Orinoco, lower R Caura and upper R Negro in E Colombia (Arauca, Vichada), W & S Venezuela and adjacent NW Brazil; birds from lower R Negro intermediate with nominate.
  • X. o. caicarae J. T. Zimmer & Phelps, Sr, 1955 – middle Orinoco Valley in C Venezuela (NW Bolívar).
  • X. o. palliatus (Des Murs, 1856) – W Amazonia, both N & S of Amazon, in SE Colombia (Meta, Caquetá), E Ecuador, E Peru, W Amazonian Brazil (E to R Negro and to R Juruá) and N Bolivia (S to N La Paz and NW Beni); birds from R Purus intermediate with nominate.
  • X. o. obsoletus (M. H. C. Lichtenstein, 1820) – E Amazonia in E Venezuela (Delta Amacuro), the Guianas and N Brazil (lower R Negro E to Amapá and, S of Amazon, from R Madeira E to R Tocantins and S to W & N Mato Grosso); populations in NE Bolivia (NE Santa Cruz) and NE Venezuela (E Monagas) likely represent this race.
