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.

A specimen of the tilefsh, Hoplolatilus fourmanoiri Smith, 1964 was collected from off Amitori Bay, Iriomote Island, Yaeyama Islands of the Ryukyu Islands, Japan. It represents the northernmost record for the species and the first record of the species from Japan. Hoplolatilus fourmanoiri can be distinguished from its congeners by the following combination of characters: caudal fin not forked; pointed spines located at corner of the preopercle and the mid-posterior margin of the opercle; maxillary broad, its maximum depth almost equal to diameter of pupil; ctenii of scales prominent; a large dark blotch located at posterior tail to caudal fin; a yellow band running from head to shoulder. The present specimen has a slightly deeper head (69.7% of head length vs. 62–68%) and more scales below lateral line (42 vs. 34–41) than other specimens, but these differences are insignificant. The dark posterior blotch of the present specimen is paler and more yellowish than the previous report, however the body coloration of the Japanese specimen is paler, which we feel is due to the condition of the specimen. The shape of the caudal fin of H. fourmanoiri was formerly described as truncate with dorsal produced. We described it as shallow double truncate. A new standard Japanese name “Hotarubi-sango-amadai” is proposed for the species.

ZooBank is intended as the offcial registry of Zoological Nomenclature, according to the International Commission on Zoological Nomenclature. Since its launch in 2005, more than 73,000 records of Nomenclatural Acts, >29,000 Publications, and >11,000 Authors have been deposited in ZooBank as of this writing. An explanatory introduction for ZooBank and proposed three scenarios for mandatory registration of names governed by the International Code of Zoological Nomenclature is given in the Japanese language to popularize relevant issues in domestic taxonomic researchers

A specimen of Sargocentron rubrum (Forsskål, 1775) and two specimens of Scarus ovifrons Temminck and Schlegel, 1846, caught by local fishermen off the coast of Kyoto Prefecture, Japan in December 2021, represent the first and northernmost records in the Sea of Japan, respectively. Both species are likely to have been transported northwards by the Tsushima Warm Current. Because the two specimens of S. ovifrons were collected at almost the same time in adjacent areas, it is possible that they had been part of an aggregation of individuals. Because S. ovifrons contains a palytoxin-like toxin, great care should be taken to avoid its accidental sale at fish markets.

Around a hundred of brachylaimid trematodes were found from the small intestine of a carrion crow (Corvus corone) in Hokkaido, Japan. Based on the result of mitochondrial DNA barcoding, the parasites were identified as Brachylaima ezohelicis Nakao, Waki and Sasaki, 2017. This is the first record of a natural definitive host for B. ezohelicis. Although most of them were at the gravid adult stage, their body sizes varied widely. This species was described by using the specimens from experimentally infected mice. When compared with the original description, the crow-derived specimens were longer in total body length and has smaller testes and a wider uterine space, probably due to better development in the suitable host. The difference provides a cautionary tale about the plasticity of morphology in trematodes. Our finding strongly suggests that birds are more suitable than mammals in serving as definitive hosts for B. ezohelicis.

A single adult specimen (348.5 mm standard length) of Lethrinus reticulatus Valenciennes, 1830 (Teleostei: Perciformes: Lethrinidae), herein described in detail, was collected from Amami-oshima island, Amami Islands, Ryukyu Islands, Japan. In Japanese waters, this species has been known only from the Okinawa and Yaeyama islands, Ryukyu Islands, and is categorized as Near Threatened by Ministry of the Environment Government of Japan. The Amami specimen represents the first record of L. reticulatus from Kagoshima Prefecture and the northernmost record for the species.

佐渡を含む新潟県内の各地から採集したテツギョ44尾について,若干の外部ならびに内部の形態形質を調べ,さらにそのうち12尾については染色体を観察した。その結果,尾鰭の長さは,フナに似て短かいものから,体長の半分に達するものまであり,全長/体長の比は,1.38〜1.65の値を示した。得られたテツギョの大半は3倍体で,3n=153であり,これらの腸型はキンブナないしナガブナに固有のA型であった。一方,佐渡の2地点より得た2倍体のテツギョの腸型は判定不能であり,その複雑さより,キンギョとフナの雑種でないかと考えられた。2倍体のテツギョは両性よりなるが,3倍体はすべて雌であり,しかも2倍体や3倍体のフナと混生していた。また,地方差を比較するために,魚取沼蛮のテツギョ2尾の染色体を詞べたところ,染色体数約100の2倍体であった。

Treatments of species taxonomy for Japanese mammals in “Illustrated Checklist of the Mammals of the World” (CMW) published in 2020 and nine volumes of “Handbook of the Mammals of the World” (HMW) from 2009 to 2019 are compared with those in the second edition of “The Wild Mammals of Japan” (WMJ2) in 2015. Then, the updated taxonomy and current problems of Japanese mammals were discussed. Order Eulipotyphla in CMW and HMW combined orders Soricomorpha and Erinaceomorpha in WMJ2, and Order Cetartiodactyla in CMW joined orders Artiodactyla and Cetacea in HMW and WMJ2; both in reflecting the recent molecular phylogenetic studies. A comparative list of the species names of Japanese mammals between CMW and WMJ2 was made, also with reference to descriptions and literatures in HMW. In CMW, 160 species are found in Japan, and 21 species of them had species names different from WMJ2. Concerning about these species and about species necessary for special consideration in species taxonomy or geographic range, 34 comments were provided for discussion.

The labrid genus Suezichthys Smith, 1958 includes 11 valid species, four of which have been recorded from the Japanese waters. Three specimens (125.2–137.7 mm standard length) of the Northern Rainbow Wrasse Suezichthys notatus (Kamohara, 1958) were collected from Tosa Bay and the East China Sea. These specimens possess the following characters: dorsal-fin rays IX, 11; anal-fin rays III, 10; scale rows above lateral line 2 1/2; lateral-line scales 25, each with unbranched laterosensory canal tube; and dark brownish blotches on head and body above pectoral fin. Suezichthys notatus, distributed in scattered localities of the eastern Indian Ocean and the Pacific Ocean, has been recorded only from Okino-shima island, Kochi Prefecture, on the basis of a holotype in the Japanese waters. Therefore, the present specimens represent the second records of the species from Japan.

A questionnaire of the use of discriminatory Japanese animal names was conducted among the physically and/or mentally handicapped persons and their supporters. Of 178 respondents, only 35 (19.7%) had already known the problem of discriminatory Japanese animal names, but 44 (24.7%) found this form of discrimination problematic or hateful. Ninety-six (53.9%) of them agreed to renaming of the mekura-nezumi ("blind rat"=mole rat), one of the typical discriminatory Japanese animal names. Renaming of non-typical discriminatory Japanese names, such as ahoudori ("fool bird"=albatross) and namakemono ("idle person"=sloth), drew fewer positive responses. Quantification II was used to detect some relationships between the respondents and their personal traits. Quantification III was adopted to examine some relationships among the questions through the attitudes of the respondents.

Leeches (subclass Hirudinida) are very famous as blood-suckers. But taxonomic studies of leeches in Japan have been scarcely advanced after Dr. Asajiro Oka's death. In addition, Japanese morphological terms of leeches have been also confused for a long time. Therefore, this paper clarifies their Japanese morphological terms with briefly reviewing their morphology for the purpose of improving the taxonomic studies of leeches in Japan. Leeches possess two suckers and 34 somites with subdivided annuli. They have eyes and an anus on dorsal, and a male and female gonopore on ventral. Their internal morphology, such as digestive system or reproductive system, is as important as their external morphology for the taxonomy of leeches. Haematophagous species have crop and intestinal ceca for storing and digesting blood. In contrast, macrophagous taxa, like Erpobdelliformes, have simple tubular digestive system. They have the male and female reproductive system located ventral to the digestive system. Each Japanese term is connected with English equivalents and illustrations in this paper in order to prevent further confusion of the Japanese morphological terms.

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.

Two specimens (201.6–205.9 mm standard length) of Hippocampus spinosissimus Weber, 1913 (Gasterosteiformes: Syngnathidae), previously recorded from the Indo-West Pacific from India east to the Philippines, north to Taiwan, and south to northern Australia, were collected at a depth of 20 m off Tanega-shima Island, Osumi Islands, Kagoshima Prefecture, southern Japan. These specimens, described here in detail, represent the first records from Japan and the northernmost record for the species. A new standard Japanese name “Tamayori-tatsu” is proposed for the species.

Brachylaimoidea Joyeux and Foley, 1930 includes seven families, and most of them use terrestrial mollusks as intermediate hosts. Among them, trematodes of the genus Brachylaima Dujardin, 1843 (Brachylaimidae Joyeux and Foley, 1930) use terrestrial mollusks as both the first and second intermediate hosts. Nine species of Brachylaima have been reported in Japan, and five of them were recently described with their DNA barcodes based on the nuclear 28S ribosomal RNA and mitochondrial cytochrome c oxidase I gene. High specificity of each species to the first intermediate host suggests the diversity of trematodes of Brachylaima including undiscovered species. Panopistidae Yamaguti, 1958 is also a family of Brachylaimoidea, but its taxonomic position in the superfamily is uncertain, because the DNA barcodes of only one species were deposited. In addition, some genera such as Michajlovia Pojmańska, 1973, Urogonimus Monticelli, 1888, and Urotocus Looss, 1899 are treated as incertae sedis because of the lack of genetic data of related species. Additional sampling from the intermediate host snails and the final host and phylogenetic analyses are needed to solve the problems in the taxonomy of Brachylaimoidea.

More than 1,300 species of fishes have been reported from the Japanese side of the Sea of Japan. However, occurrence records for a great number of these species are not documented by voucher specimens, rendering estimates of the diversity of fishes from this region unclear as to their reliability. Given this situation, ichthyologists at the Maizuru Fisheries Research Station of Kyoto University are central to a research group aiming to provide a more reliable estimate of the diversity of the fish fauna of this region that is based on a reproducible data such as voucher specimens. Here we provide some biogeographic (24 species) and taxonomic (2 species) notes as a preliminary report towards this goal. As a result of new biogeographical findings, 10 species are confirmed from this region for the first time, and the distributional ranges of 14 other species are extended to the east. Most of these 24 species are not residents in the Sea of Japan, rather they are migratory species likely to have drifted from the southward via the Tsushima Warm Current. An unidentified congrid species, Ariosoma sp. and an undescribed cynoglossid species, Symphurus sp., were collected off Kyoto Prefecture. Exact identification of the former species, and a description and formal naming for the latter species, will be the subject of studies conducted in the near future.

The dicrocoeliid trematode Lutztrema attenuatum (Dujardin, 1845) has been reported from its definitive hosts, passerine birds worldwide, whereas its larvae have never been detected in natural fields. In this study, 41 adults of Lu. attenuatum were obtained from dead specimens of Turdus pallidus Gmelin, 1789 and T. eunomus Temminck, 1831, and the partial sequence of the mitochondrial COI gene and nuclear 28S rDNA were determined from one of the specimens as DNA barcodes. Furthermore, during a land snail survey in Tokyo, Japan on 11 August 2021, dicrocoeliid sporocysts and cercariae were detected from the achatinid Allopeas satsumense (Pilsbry, 1906). The partial COI sequence of the sporocysts showed a p-distance value of less than 1.4% to that of the adult Lu. attenuatum. The sporocyst was identified molecularly as Lu. attenuatum based on an empirical intraspecific genetic variation in dicrocoeliids, and thus A. satsumense found to be its first intermediate host. We also provided DNA barcodes to an adult specimen of Lyperosomum sp. (Dicrocoeliidae) detected from the same dead specimen of T. pallidus.

A single adult specimen (192.2 mm standard length) of the Malabar Trevally, Platycaranx malabaricus (Bloch and Schneider, 1801) (Teleostei: Carangidae), collected from Sagami Bay was observed in the fish collection of the Department of Zoology, The University Museum, The University of Tokyo. Because the northern limit of the distributional range of the species has been regarded as Mihama Town, Aichi Prefecture, the specimen described in this study represents the northernmost record and first record from Kanagawa Prefecture of P. malabaricus.

Four alien monogeneans, Unilatus unilatus Mizelle and Kritsky, 1967, U. brittani Mizelle, Kritsky, and Crane, 1968, Trinigyrus peregrinus n. sp., and Heteropriapulus heterotylus (Jogunoori, Kritsky, and Venkatanarasaiah, 2004), were collected from the gills of vermiculated sailfin catfish, Pterygoplichthys disjunctivus (Weber, 1991) (Siluriformes: Loricariidae), in inland waters of Okinawa-jima island, Okinawa Prefecture, Japan. Unilatus unilatus and U. brittani represent new country records for Japan. Trinigyrus peregrinus n. sp. is characterized by a coiled male copulatory organ that forms a circle and does not articulate with its accessory piece. Heteropriapulus heterotylus was newly collected from two rivers in south-central Okinawa-jima island. These monogeneans are all considered to be native to South America and to have been co-introduced with the host fish into the inland waters of the island by release of ornamental pet fish.
