Two new species of feather mites from the superfamily Analgoidea are described from the grey-headed woodpecker, Picus canus, in Korea: Neopteronyssus koreanussp. nov. (Pteronyssidae) and Proterothrix picinussp. nov. (Proctophyllodidae: Pterodectinae). Feather mites of the genera NeopteronyssusMironov, 2002 and ProterothrixGaud, 1968 are described for the first time in Korea. Morphological descriptions of both new species are complemented with partial sequences of their mitochondrial cytochrome c oxidase subunit I (COI) gene as DNA barcodes.
