A new species of oribatid mite from New Zealand, Atropacarus (Atropacarus) niedbalaisp. nov. (Phthiracaridae), shows extreme neotrichy of the prodorsum, notogaster, genitoaggenital and anoadanal plates. The combination of these features is unique and is reported for the first time for a species of oribatid mite. This new species is the most hairy known ptyctimous mite and maybe the most neotrichous case in Oribatida (109-115 pairs of notogastral setae). Meanwhile, this species is the second example of neotrichy on the prodorsum in ptyctimous mites, and the second example of neotrichy on the genitoaggenital plates in Phthiracaridae.http://zoobank.org/urn:lsid:zoobank.org:pub:509952FF-5722-4094-A343-F9B03658CDF3
