Poliohierax [sic] semitorquatus deckeni Zedlitz, 1914: 675 .

Now: Polihierax semitorquatus A. Smith, 1836 . See White (1965: 60); but see also Peters (1931: 282).

Syntype: ZMB 24395 (B 15727, Fischer no. 376), skin, former mount, female, adult, collected at “Massa” (Tana River), 02.11.[1878] .

Syntype: ZMB 2002.225 (B 591, Berger no. 50), skin, male, adult, collected by A. Berger at the “Baringo See” (Lake Baringo), 19.10.[1908] .

Syntype: SMF-11064 (Erlanger/Hilgert no. 11064), skin, collected by C. von Erlanger/C. Hilgert at “Kismaju” (Somaliland), 13.07.1901.

Syntype: SMF-11061 (Erlanger/Hilgert no. 11061), skin, collected by C. von Erlanger/C. Hilgert at “Gardolia-Djira”, 10.05.1901.

Syntype: SMF-11062 (Erlanger/Hilgert no. 11062), skin, collected by C. von Erlanger/C. Hilgert at “Gardolia-Djira”, 10.05.1901.

Syntype: NRM 569842 (Müller no. 113), skin, male, collected by C. Müller at Afgoi, 19.02.[19]11] (Zedlitz collection) .

Syntype: NRM 569843 (Müller no. 115), skin, female, collected by C. Müller at Afgoi, 04.03.[19]11 (Zedlitz collection) .

Type locality: “ Süd-Somali und Brit. O-Afrika bis zum Baringo-See” [Southern Somalia and Kenya to Lake Baringo], from the original description and localities of the syntypes.

Remarks: Zedlitz described the new subspecies based on specimens from his own collection (collected by his taxidermist and collector C. Müller) and from the collections of Carlo von Erlanger and the ZMB. He gave the collector and the locality as well as numbers. Thus the two specimens of the ZMB collection, three of the Erlanger collection (now in SMF) and the two of the Zedlitz collection (now in NRM) are syntypes. Zedlitz mentioned eight specimens from his collection, largely acquired by the NRM (Wikipedia, 02.12.2020), but six specimens are missing. This species name honors the German ornithologist Karl Klaus von der Decken (1833–1865).
