A new mite species, Riccardoella (Proriccardoella) tokyoensis n. sp., is described from the lungs of the terrestrial gastropod Tauphaedusa tau (Boettger, 1877) (Clausliidae) collected in a forest city park of Tokyo, Japan. The new species is distinguished from other Riccardoella species by the following morphological characters: tibia II bears 2 setae (vs. 3 setae in other species); femur I bears 5 setae (vs. 4 or 6 setae in other species); seta of trochanter I is absent (vs. 1 seta in other species). Our phylogenetic tree based on amino acid sequences of the mitochondrial cytochrome c oxidase subunit 1 (COX1) confirmed that another member of the family Ereynetidae, "Ereynetidae sp.", is the closest relative with 85% sequence identity.
从日本东京一个森林城市公园采集的陆地腹足纲动物陶法蜗牛（Tauphaedusa tau，Boettger，1877）（Clausliidae科）的肺中，描述了一种新的螨类物种——东京里卡螨（Riccardoella (Proriccardoella) tokyoensis）。该新物种与其他里卡螨物种的区别在于以下形态特征：第二对胫节有2根刚毛（其他物种为3根刚毛）；第一对股骨有5根刚毛（其他物种为4根或6根刚毛）；第一对转节无刚毛（其他物种有1根刚毛）。基于线粒体细胞色素c氧化酶亚基1（COX1）氨基酸序列构建的系统发育树证实，埃雷螨科的另一个成员“埃雷螨科物种”是其最亲近的亲属，序列同一性为85%。
