polioptera / poliopterus
Gr. πολιος polios  grey; -πτερος -pteros  -winged  < πτερον pteron  wing (pace Clark & Davies 2018 (under Melierax), "The species name, poliopterus, is from the Greek polios for 'grey' and pleura for 'the side'").

Ad ♀ is duller and greyer on the head with chestnut primaries." (Stevenson & Fanshawe 2002); "La soi-disant Muscicapa lugubris, du baron de Muller, est peut-être une des nouvelles Melænornis de Sundeval; toutefois, s'il a voulu illustrer une espèce abyssinienne que nous conservons dans le Musée de Paris, nous lui trouvons un aspect Saxicolien qui nous la fait rapprocher des genres Gervaisia, Bp., et Thamnolæa, Cab.: nous en constituons le genre Poeoptera, Bp., et nous appellerons l'espèce lugubris, qu'elle soit ou non la lugubris, Mull., Nouv. Ois. d'Afrique, I, t. 2.  Atro-cyanea: remigibus interne subtusque latissime cinereo-chalybæis." (Bonaparte 1854); "Poeoptera Bonaparte, 1854, Compt. Rend., 38, p. 381.
