Lavoipierre & Griffiths (1951) described the female, and Lavoipierre (1953) described the male, of Knemidokoptes pilae found on a budgerigar. Later, Oldham & Beresford (1954) and Evans & Browning (1955), respectively, added Psittacula nipalensis and Upupa epops to the host-list of this species. The present author (1956) has also mentioned the occurrence of Knemidokoptes pilae on a budgerigar and a parrakeet, Palaeornis torquatus, and an unknown species of the genus Ara may now be added to the list.
