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 genus Riccardoella Berlese, 1923 (Ereynetidae Oudemans, 1931) consists of eight species, and six of the eight species were reported and described from the lungs of terrestrial mollusks, and the remaining two were from soils. In Japan, three of the eight species have widely been reported from terrestrial mollusks. In this manuscript, we introduce species identification based on morphology, distribution, and hosts of these three Japanese mite species. Sampling methods, preparations of slide specimens and virulence of these mites were also added.

My studies of zoological taxonomy were initiated using oribatid mites as study objects. I also had the idea of looking into the biology of these mites and eventually, we were the first to discover a pheromone (geranial) produced by oribatid mites. Next, we discovered that one of the substances of the external secretion from oribatid mites serving as a defense against enemies, contains a poisonous component also used by their predator, the poison frog with bioconcentration. Geranial and neral are chemical isomers which are produced and secreted by oribatid mites. The astigmatid mites derived from the oribatid mites share the same substance (neral) as a secretion material. The traditional method of ripening a few kinds of European cheese with astigmatid mites seems to partly impart the lemon flavor of the neral to the cheese.I have switched my research to the ecology and agricultural use of soil protists in the past, to obtain a position in the research institute of the Ministry of Agriculture, Forestry, and Fisheries. Eventually, however, I focused my research towards zoological taxonomy again, but now for protists and finally, I was also involved in the revision of the eukaryotic classification.During the study of endangered species, we redescribed the testate amoeba species, Difflugia biwae Kawamura, 1918, in the ancient Lake Biwa in Japan. We also discovered that the feather mite Compressalges nipponiae Dubinin, 1950, which was known to dwell in the wings of the Japanese Crested Ibis, had become extinct along with the Japanese lineage, and re­described the species.Scolopendra alcyona Tsukamoto & Shimano, 2021, described from the Ryukyu Islands in cooperation with local citizens, is the third semi-aquatic species of the genus Scolopendra Linnaeus, 1758 in the world, and the first species of the genus described in 143 years. Moreover, it is the first centipede species described by Japanese researchers in this giant centipede genus.Ameronothrus twitter Pfingstl and Shimano, 2021, oribatid mite, was voted by the World Register of Marine Species (WoRMS) as one of the “Ten remarkable new marine species from 2021” as “the Japanese Twitter mite” was described with the help of Twitter, a popular social networking service. It will be essential to incorporate citizen science into zoological systematics and work with the public in scientific endeavors in the future.

From 2012 to 2021, bird surveys were carried out from Kyushu to Hokkaido, Japan, including a zoo, to find feather mites (Analgoidea Trouessart & Mégnin, 1884 and Pterolichoidea Gaud & Atyeo, 1978) from raptors including owls. In this study, we detected eight feather mite species as following: Glaucalges tytonis Dabert, Ehrnsberger & Dabert, 2008, Hieracolichus nisi (Canestrini, 1878), Kramerella bubonis (Lönnfors, 1937), Kramerella aprotuberantia Dubinin, 1953, Dermonoton longiventer (Mégnin & Trouessart, 1884), Petitota aluconis (Buchholz, 1869), Pseudalloptinus aquilinus (Trouessart, 1884) and Pseudalloptinus milvulinus (Trouessart, 1884).Two of the mite species, G. tytonis and Ps. aquilinus, were only sampled from bird hosts born in the zoo of Japan but they probably originated from oversea. The five of the eight species, Hi. nisi, K. bubonis, K. aprotuberantia, D. longiventer and Pe. aluconis were first reported in Japan. Among them, Hi. nisi was detected only from endangered bird host species Aquila chrysaetos (Linnaeus, 1758)(EN: Endangered). For the mite species, it is important to examine the status of their populations to consider the extinction risk in Japan, because they may be threatened with extinction simultaneously with the decline of the host populations in the future. Three species of mites, G. tytonis, D. longiventer, Hi. nisi were first reported from the hosts Bubo bubo (Linnaeus, 1758), Strix uralensis Pallas, 1771, Haliaeetus albicilla (Linnaeus, 1758), respectively. The Ps. milvulinus was also the first reported from the hosts Buteo japonicus Temminck & Schlegel, 1844 and A. chrysaetos.

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.

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.

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.

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.

During the 3-year period (2020–2022), 49 cases of tick bites were presented to the Japanese Red Cross Ashikaga Hospital in Tochigi Prefecture, Japan. More than 60% of all tick bites between March and September occurred within two months (May and June). Amblyomma testudinarium was responsible for 40 cases among all the tick bite cases. Specifically, 41 individuals of this species (39 nymphs/2 adult females) were linked (The point estimate was 0.79 with a 95% confidence interval of 0.67–1.00). There were 38 cases of tick bites in Ashikaga City, and 23 of which occurred in the vicinity of the patients’ houses (gardens and fields). Suspected cases of Tick-associated rash illness (TARI) were first recorded in the Japanese Red Cross Ashikaga Hospital in May 2020, in a total of five cases ( i.e., the patients were aged 50 years or older). TARI is indicative of repeated tick bites, which points to the permanent settlement of the A. testudinarium in and around Ashikaga City. Therefore, we believe that greater efforts should be implemented towards the detection of tick-associated infections in this area, including Severe fever with thrombocytopenia syndrome virus for which A. testudinarium is considered as a major vector.
