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.

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.

The order Tetraodontiformes is regarded as one of the most highly derived groups among teleostean fishes and contains 435 species among 104 genera of 10 families. They have been studied in various academic disciplines such as phylogeny, anatomy, toxicology, fisheries, and genome biology. In this review, I present a series of studies on the phylogeny and taxonomy of tetraodontiform fishes of various taxonomic levels led by me. The studies involved various aspects such as the phylogenetic position and sister group of the order, familial relationships, relationships between balistids and monacanthids and evolution of pelvic elements, phylogeny and timescale of fugu of the genus Takifugu, relationships between tetraodontid fishes and their adaptation process to freshwater, and taxonomy of molids of the genus Mola. The results of these studies proposed evolutionary hypotheses that are largely incongruent with the conventional ones and revealed many problems regarding their taxonomy and classification.

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.

Reproductive isolation and evolution of copulatory organ in eleven interstitial species of the genus Parapolycope (Ostracoda, Myodocopida) were discussed. The shapes of male ejaculatory duct are divided into the three types i.e., a helical tube type (Type H), a curved short tube type (Type S), and tapering long tube type (Type L). And the correlation between the shapes of copulatory organs in both sexes is recognized as, what we call, the "lock and key". After copulation, the female genital openings of Parapolycope sp. 2 are often blocked by a rod-shape structure. The rod-shaped structure is thought as a part of the male copulatory duct. The phylogenetic relationships of several Parapolycope species were estimated by the mitochondrial COT gene sequences. According to this, the extremely long type of copulatory duct must have evolved gradually from the short curved tube type. As a hypothesis to explain the development of the extremely long type of ejaculatory duct, the concept of an "evolutionary arms race" would be applicable.

Larval cestodes of Anthobothrium sp. (Cestoda: “Tetraphyllidea”) were collected from the gills of the bigfin reef squid, “shiroika” Sepioteuthis lessoniana Férussac in Lesson, 1832 (Cephalopoda: Loliginidae) collected off Shirahama in Wakayama Prefecture, Japan. These specimens were morphologically described with DNA information (28S rDNA and cox1) and reported as a new host record. In addition, records of Anthobothrium species in Japan were compiled, and a list of parasites and symbionts of S. lessoniana was provided.

In recent years, the classification system of Unionoida (Margaritiferidae, Unionidae) has undergone major changes from conventional methods by shell morphology, due to breakthroughs in approaches based on molecular phylogenetic analysis. We compared the classification system trends of the Margaritiferidae and Unionidae distributed in Japan, and pointed out that there is a time lag to the classification determinations of the latter. Although the scientific names have been changed, the existence, distribution, and ecological information (ex. host fish for glochidia) of two Japanese margaritiferids have been established, and conservation measures and regulations based on the Red List and laws can be expected. On the other hand, the Unionidae consisted of 3 subfamilies, 11 genera and 15 species has increased to 2 subfamilies, 13 genera and 26 species (excluding alien species) by the new classification system reported in 2020. Therefore, information on the distribution and ecology of many new species must be elucidated. A new classification system will be assumed the further revision, especially for the genus Sinanodonta, and the risk of some local populations extinction increase before clarifying the actual situation of species. We are now proceeding to clarify the early life stage of some Unionoida mussels (ex. parasitic stage, salinity tolerance), but insufficient knowledge of the life cycle of Unionoida has prevented the establishment of complete ex-situ conservation methods. Conversion project of numerous reservoirs are that the most important habitats for Unionidae species pressing forward in Japan. In light of this situation, it is hoped that the new classification system that can serve as a basis for on-site conservation will spread throughout as soon as possible to realize comprehensive conservation.
