Now Vidua wilsoni (Hartert, 1901) . See Hartert, 1919a: 143 ; Mayr et al., 1968: 394 ; Dickinson, 2003: 737 ; Fry and Keith, 2004: 439–440 ; and Payne 2010: 228 . HOLOTYPE : AMNH 452337 , adult male, collected at Yelwa , 10.48N , 04.42E (Times atlas), middle Niger River , Nigeria , on 2 August 1899 , by Malcolm Wilson. From the Rothschild Collection. COMMENTS: Hartert based his description on a single male specimen from Yelwa, but said that another specimen from Rabba on the Niger in BMNH probably belonged to the same taxon. Hartert used the spelling Hypochaera in his description of H. wilsoni as a full species, not as a subspecies of H. furnerea as in Fry and Keith (2004: 439) .
