ABSTRACT

The present paper provides information on juvenile stages of seven intertidal oribatid mite species from the East Asian region. Larva and nymphs of the fortuyniid species Fortuynia churaumi, F. shibai, F. rotunda and Alismobates reticulatus are described and details about juvenile morphology of the selenoribatid species, Arotrobates granulatus, Indopacifica taiyo and I. tyida are given. Juveniles of the genus Arotrobates are reported for the first time and strong ventral femoral carinae are supposed to be diagnostic characters. Basically, the conservative morphology of immature stages could be confirmed in every studied taxon and its importance for phylogenetic considerations is emphasized.

 抽象的

本文提供了东亚地区七种潮间带螨类幼虫阶段的信息。描述了 Fortuyniid 物种Fortuynia churaumi、F. shibai、F. rotunda和Alismobates reticulatus的幼虫和若虫，并详细介绍了 selenoribatid 物种、 Arotrobates 管理的幼虫、Indopacifica taiyo和I. tyida 的幼虫形态。首次报道了Arotrobates属的幼体，强烈的腹侧股骨隆突被认为是诊断特征。基本上，未成熟阶段的保守形态可以在每个研究的分类单元中得到证实，并且强调了其对系统发育考虑的重要性。
