A new revision of the higher taxonomic classification of eukaryotes was published in 2019 in the journal of the International Society of Protistologists, Journal of Eukaryotic Microbiology. In the seven years since the last revision made in 2012, the large-scale multigene phylogenetic analyses in the background of the recent advancement of sequencing technology have revealed the affiliation of many “orphan” lineages and taxa. The major changes in this revision are the following four points: i) Excavata is not adopted to be a clade, ii) CRuMs as an assembly of Collodictyonida, Rigifilida, and Mantamonas is adopted to be a clade as the relatives of Amorphea, iii) Haptista consisted of Haptophyta and Centrohelida is adopted as a new clade, and iv) Crypista is also adopted as a new clade.

The International Society of Protistologists (ISOP) published a new classification of eukaryotes using ‘supergroups’ in 2005, which was subsequently revised in 2012. The revised classification now reflects the knowledge of protist evolution, reintroduces some formality with group names and their authority, and provides a point of reference for protist systematics. In the present review, the ISOP's revised classification with five supergroups is compared with a hierarchical classification of the Catalogue of Life (CoL)'s database and then the significance of the following three main points are explained: (i) the Chromalveolata hypothesis was rejected and the supergroup SAR was accepted, (ii) Amorphea (including mainly Amoebozoa and Opisthokonta) was proposed, and (iii) Diaphoretickes (including mainly SAR, Archaeplastida, and a group once called “Hacrobia”) with the exception of Excavata was also proposed.

The taxon-group of Acari has most number of valid species (almost 55,000) in Arachnida, however Acari was disappeared in textbooks of invertebrate nowadays. Acariformes and Parasitiformes sensu lato are used as separated taxon-groups instead of Acari. Although two-name system, tick (sucking blood) and mite (others) were common for meaning Acari in some countries, Japanese use one word “dani” for Acari. French use three categories, tick, mite and ciron (ceron). The “ciron” means cheese mites (and some small bugs) and was used as the symbol of minimums in some French literature (e.g. Fables by Jean de la Fontaine in 1668, Pensées by Blaise Pascal in 1670). Acarine species are recorded almost 2,000 in Japan, and 1% (almost 20 species) of them are harmful as common sucking blood ticks. Acari have diverse eating habits, while other members of Arachnida are only predators. The diversity of Acarine eating habits may have maintained species diversity of them. Oribatida as a decomposer has various physical appearance. The much morphological diversity is a strategy to defend against predators. The oribatid mite have not only morphological defense but also chemical defense as chemical secretion from opisthonotal glands and physical defense as jumping. These various defense strategies are also helpful in maintaining diverse species.

We report parasitic mites from six species of land snails, which are listed in Prefectural Red Lists and/or Red Data Books authorized by Ministry of the Environment Government of Japan and Prefectural Governments in Japan; Riccardoella reaumuri Fain and van Goethem, 1986 were found from Euhadra brandtii sapporo Ijima, 1891 in Hokkaido, Oxyloma hirasei Pilsbry, 1901 in Ibaraki, and Phaeohelix submandarina Pilsbry, 1890 in Kagoshima. Riccardoella tokyoensis Waki and Shimano, 2018 were sampled from Tauphaedusa tau Boettger, 1877 in Ibaraki, Megalophaedusa surugensis Kuroda, 1936 in Kanagawa, and Megalophaedusa yagurai Kuroda, 1936 in Tokyo. Extinction risks of the two mites should be low because they are found in land snails which are currently common and do not appear in any categories of Red List and Red Data Book.

Several of the recent higher classification systems of “Acari” were reviewed. The taxon group as “Acari” finally disappeared in recent systems. A correspondence table between the recent higher systems reached a consensus based on phylogenetic papers and the old system with 7 suborders (general in Japanese text books) were provided with some Japanese name of taxon groups appropriately modified in the present paper. Japanese name of Poecilophysidea (Acariformes + Solifugae) was also proposed.

新潟県からSymbioribates属の1新種を採集し,Symbioribates yukiguni sp. nov.(ユキグニフタカタダニ)と命名し記載した.本属はこれまで,熱帯地域及び亜熱帯地域から記録されたが,本種は温帯域から発見された.ユキグニフタカタダニは,Symbioribates papuensis Aoki, 1966及びSymbioribates aokii Karasawa & Behan-Pelletier, 2007に似ているものの,雌雄ともに体長・体幅が両種よりも大きいこと,また,雄は背孔A_3が近接しているが,融合しておらずh_1は背孔の外に位置していること,雌は胴感毛が後体部前縁には完全には覆われておらず,背孔Aa,A_1が他の種に比べて大きく,さらに吻毛(ro)と桁毛(le)が長いことから容易に区別される.
