Taxonomy
The white-bearded antshrike was
described by the French ornithologist
Frédéric de Lafresnaye in 1850 and given the
binomial name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, bot ...
''Anabates nigro-pectus''.
The genus was erected by the German ornithologists
Jean Cabanis and
