The scale-backed antbird (''Willisornis poecilinotus'')〔(ENGLISH NAME UPDATES - IOC Version 2.9 (July 10, 2011) ), IOC World Bird List〕 is a species of bird in the family Thamnophilidae, the antbirds. It has often been included in the genus ''Hylophylax'', but is now known to be part of a different clade, leading to its placement in the genus ''Willisornis''. It was briefly placed in ''Dichropogon'', but this name is preoccupied by a genus of asilid flies (''Dichropogon'' Bezzi, 1910).〔(Revive the genus Dichropogon ) - South American Classification Committee (2007)〕〔(Reassign ''Dichropogon'' to ''Willisornis'' ) - South American Classification Committee (2008)〕 It formerly included the Xingu antbird as a subspecies.〔Isler & Whitney (2011). ''Species limits in antbirds (Thamnophilidae): The Scale-backed Antbird (Willisornis poecilinotus) complex.'' Wilson Journal of Ornithology 123(1): 1-14〕 It is found in the Amazon of Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitat is tropical moist lowland forests. As many other species of antbirds, it regularly follows swarms of army ants. In addition to being sexually dimorphic, the plumages of the subspecies are highly variable, leading to speculations that the scale-backed antbird as presently defined may include more than a single species. Males of all subspecies, and females of some (but not all) subspecies have white bars on the back, leading to its common name scale-backed antbird. ==References== * BirdLife International 2004.
