Compressalges nipponiae Dubinin, 1950

Japanese crested ibis parasitic mite



Taxonomy & Nomenclature



Conservation Status


An extensive recent study of living Japanese crested ibises (Nipponia nippon) (the only known host) has failed to find any living Compressalges nipponiae (Waki & Shimano, 2020).




Compressalges nipponiae has only ever been recorded from Japanese crested ibis (Nipponia nippon) of Japanese origin. A recent study did not find any living C. nipponiae on birds introduced from the rediscovered Chinese population of Japanese crested ibis (Nipponia nippon), and they wrote: "we recommend a revision of the status of C. nipponiae to “EX” in near future" (Waki & Shimano, 2020).
