But now I am a little bit confused about the authorship. Will be Theodor von Heuglin or Gustav Hartlaub be considered as author of the name? I ask as the title of the article is Beiträge zur der Ornithologie von Th. v. Heugelin while at the end of the article we Dr. G. Hartlaub.
As well I ask myself (if Avibase is correct) why Apus affinis galilejensis (Antinori, 1855) and not Apus affinis abessynicus (Streubel, 1848)? abessynicus pre-occupied by?
But Thesaurus ornithologiae shows it as synonym to Apus affinis affinis.
Streubel indicated here Ethiopia as country where Friedrich Wilhelm Hemprich and Christian Gottfried Ehrenberg collected the specimen(s).
I am honest I can't follow this logic here of plenary powers.
