Genera included. The subfamily includes 11 genera: Calamincola Casto, 1978 , Columbiphilus Kivganov and Sharafat, 1995 , Charadriineopicobia Skoracki et al ., 2014 , Gunabopicobia Skoracki and Hromada, 2013 , Lawrencipicobia Skoracki and Hromada, 2013 , Neopicobia Skoracki, 2011 , Phipicobia Glowska and Schmidt, 2014 , Picobia Haller, 1878 , Pipicobia Glowska and Schmidt, 2014 , Pseudopicobia Skoracki et al ., 2012 , and Rafapicobia Skoracki, 2011 . Distribution and host range. Members of this subfamily are known from all zoogeographical regions, except for Antarctica , and occupy wide spectrum of avian host: Charadriiformes , Columbiformes , Coraciiformes , Cuculiformes , Galbuliformes , Galliformes , Gruiformes , Passeriformes , Piciformes , Psittaciformes , and Pteroclidiformes . Habitat. All species of this subfamily inhabit quills of contour feathers of the head, neck, breast, abdomen, and back regions, except representative of the monotypic genus Calamincola , i.e. C. lobatus Casto, 1977 inhabiting quills of flight feathers.
