TL;DR: The purpose of this application, under Article 81 of the Code, is to conserve the accustomed usage of the name Thamnophilus schistaceus d'Orbigny, 1838, for an antshrike confusingly treated in the works that dealt with the findings of d'Obrigny during his travels in southern South America almost 200 years ago.
Abstract: The purpose of this application, under Article 81 of the Code, is to conserve the accustomed usage of the name Thamnophilus schistaceus d'Orbigny, 1838, for an antshrike confusingly treated in the works that dealt with the findings of d'Orbigny during his travels in southern South America almost 200 years ago The name has been almost wholly consistently used since its introduction, but is now potentially threatened by evidence revealed during bibliographic research
