Type material examined. Two female paratypes from nest of Columba livia Gmelin (Columbiformes: Columbidae), AFGHANISTAN: Kabul, 10–20 September 1991, coll. G. S. Sharafat, all material in OCU.
Additional material. Two females (NPF) from Gallus gallus domesticus (Linnaeus) (Galliformes: Phasianidae), BELGIUM: 14 September 1960, coll. A. Fain, all material in RBINS; 1 female (NPF), 1 female (PF) and 4 males from Coturnix coturnix (Linnaeus) (Phasianidae), JAPAN: Hokkaido, 20 September 1906, coll. unknown, all material in AMU; 1 female (PF) from Francolinus clappertoni Children and Vigors (Phasianidae), CENTRAL AFRICA: no other data, specimen in AMU; 1 female (NPF) from Acryllium vulturinum (Hardwicke) (Galliformes: Numididae), bird imported to ZOO-garden in France from the EASTERN AFRICA, specimen in AMU; 1 female (NPF) from Numida meleagris mitratus (Pallas) (Numididae), SOUTH AFRICA: Transvaal, 1959, coll. unknown, specimen in RMCA.
Host range and distribution. Metastenoxenous species associated with galliform birds (Galliformes). Phasianidae: Coturnix coturnix (Linnaeus) [new host] from Japan, Francolinus clappertoni Children and Vigors [new host] from Central Africa (present paper), Gallus gallus domesticus (Linnaeus) from Afghanistan (Kivganov & Sharafat 1995), Belgium (present paper), Germany (Skoracki & Sikora 2011), Poland (Skoracki et al. 2001), USA (Skoracki et al. 2014a), and G. sonneratti Temminck from India (Skoracki & Sikora, 2011).
Numididae: Acryllium vulturinum (Hardwicke) [new host] from Eastern Africa and Numida meleagris mitratus (Pallas) [new host] from South Africa (present paper).
Remarks. This species was described from females originally collected from the nest of Columba livia Gmelin, and for long time this bird species has been taken as a natural host for Columbiphilus khushalkhani (Kivganov & Sharafat 1995; Bochkov & Mironov 1998; Skoracki 2011). In a recent paper, Skoracki and Sikora (2011) questioned C. livia as a natural host for C. khushalkhani based on the composition of the quill mite fauna from other species of pigeons, which are exclusively inhabited by representatives of the genus Gunabopicobia (see Table 1). They also suggested an accidental transfer of C. khushalkhani from a domestic hen to nearby nesting doves. Recently, we received information that the type material of C. khushalkhani has been indeed collected from a pigeon-nest located in the henhouse (Dr. D. Kivganov, personal comm., 2015). Additionally, the examination of the type material of C. khushalkhani allows the synonimization of C. polonica (Skoracki, Magowski and Dabert, 2001) syn. nov., previously known as parasite of domestic hen. This means that members of the genus Columbiphilus are associated only with birds of the order Galliformes and unfortunately the generic name Columbiphilus does not suggest the real association of these quill mites with galliform hosts and not columbiform hosts.
