Pucheran and Lafresnaye, 1850,
Pebas, north bank of Amazon, Loreto, Peru#R.
Until recently considered conspecific with X. ocellatus from S of R Amazon, but recent study#R found deep level of genetic divergence; moreover, on basis of cited evidence#R, there is a marked difference in voice between birds N and S of Amazon. Name beauperthuysii replaces previously used weddellii, as latter is junior, has very vague type locality, and may even refer instead to X. ocellatus#R. Range of lineatocapilla uncertain; known only from type, reported to be from Ciudad Bolívar (C Venezuela), but that appears erroneous. Two subspecies recognized.
