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.
