WILLISORNIS
(Thamnophilidae; Ϯ Common Scale-backed Antbird W. poecilinotus) Dr Edwin O’Neill Willis (1935-2015) US ornithologist resident in Brazil; Gr. ορνις ornis, ορνιθος ornithos  bird; "Charles Chubb (1918) established the monotypic genus Dichropogon for the Scale-backed Antbird, originally described as Hypocnemis poecilonota Cabanis, 1847.  ...  However, this name is preoccupied by Dichropogon Bezzi, 1910, for a genus of Palaearctic asilid flies  ...  In lacking an available and potentially valid synonym, we propose to replace Dichropogon Chubb, 1918, by the name:  WILLISORNIS NOM. NOV.  ...  This genus is named after Edwin O'Neill Willis in recognition of his substantial contributions to the knowledge on the Thamnophilidae made during the past four decades" (Agne & Pacheco 2007).
