Emersoniella paraboliceps ( Piaget, 1880) , new combination

Nirmus paraboliceps Piaget, 1880: 135 .

Brueelia pataboliceps ( Piaget), 1880 ; Hopkins & Clay 1952: 60.

Type host. Probosciger aeterrimus (Gmelin, 1788) — palm cockatoo.

Remarks. The single male (the holotype) in the Piaget collection at NHML belongs to Emersoniella . This genus is normally found on kingfishers ( Alcedinidae ), and the occurrence on a parrot is most likely the result of an incorrect host association due to a misidentification of the host, a contamination, or a straggling event. Using the key of Gustafsson & Bush (2014), it keys out to E. crassicarina , but differs from this species in the male genitalia, head shape and abdominal chaetotaxy. Therefore, we believe it is likely another species from an unknown host.
