ABSTRACT The Ameronothridae are recorded for the first time from Japanese coasts with the new species Ameronothrus yoichi sp. n. from Hokkaido. The report of this species represents the most southern occurrence of an Ameronothrus species in the Asian Pacific region. Ameronothrus yoichi sp. n. can be easily distinguished from its congeners by the conspicuously pusticulate body surface and the loss of dorsal companion setae d on all genua in the adult stage. Based on adult and juvenile morphology, a close relation to Ameronothrus maculatus and A. schneideri is suggested. Ameronothrus yoichi sp. n. is classified as a lichenivorous inhabitant of sediment-free rocky coastal substrates. Due to a lack of genetic sequence data of nearly all ameronothrid species a molecular genetic comparison is yet unfeasible, but a Bayesian inference tree based on the 18S rRNA gene shows a paraphyletic clustering of the ameronothrid A. yoichi sp. n. and Paraquanothrus grahami. http://www.zoobank.org/urn:lsid:zoobank.org:pub:5B772E2C-7D5E-4C86-9955-AB84A84C50DA Graphical abstract

来自日本的 Ameronothridae (Acari, Oribatida) 的首次记录——新种、幼鱼形态、生态学和生物地理学评论

摘要 Ameronothridae 首次从日本海岸被记录到新物种 Ameronothrus yoichi sp。n. 来自北海道。该物种的报告代表了亚太地区最南端的 Ameronothrus 物种。Ameronothrus yoichi sp. n. 可以很容易地通过显着的脓疱体表面和成年阶段所有膝上的背侧伴刚毛的丧失而与其同类区分开来。根据成虫和幼虫的形态，建议与 Ameronothrus maculatus 和 A. schneideri 有密切关系。Ameronothrus yoichi sp. n. 被归类为无沉积岩石海岸基质的苔藓植物。由于缺乏几乎所有菊科物种的基因序列数据，分子遗传比较尚不可行，但是基于 18S rRNA 基因的贝叶斯推理树显示了 ameronothrid A. yoichi sp. 的并系聚类。n. 和 Paraquanothrus grahami。http://www.zoobank.org/urn:lsid:zoobank.org:pub:5B772E2C-7D5E-4C86-9955-AB84A84C50DA 图形摘要
