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.

At least ten families of the molluscan class Gastropoda contain parasitic species. Parasitic gastropods exhibit an extraordinarily large number of species and wide varieties of morphologies and host-exploitation strategies. Here, I introduce our evolutionary studies based on molecular phylogenetic analysis for two lineages of parasitic gastropods: Caledoniella (Caledoniellidae) and Eulimidae. Species of Caledoniella parasitize stomatopods (mantis shrimps) and have close phylogenetic kinship to burrow commensals of marine benthic invertebrates. Interestingly, Sigaretornus sp. from mantis shrimp burrows was found to be sister to Caledoniella, suggesting the following evolutionary scenario from free-living organisms to parasites: (1) colonization into benthic invertebrates’ burrows, (2) specialization to mantis shrimps, and (3) habitat-shift to the host body surface with the acquisition of the parasitic nature. Members of the other group Eulimidae show the widest range of parasitic strategies (i.e., temporary, ecto- and endoparasitism) on their echinoderm hosts. Molecular phylogenies of the family have revealed the polyphyly of endoparasitic taxa and repeated evolutionary changes from slender to globose shells. Recurrent specializations to the parasitic mode of life probably have an important role in the diversification of eulimid gastropods.

An amendment to the International Code of Zoological Nomenclature was passed on 4th Sept 2012 that formally establishes ZooBank as the online version of the Official Register of Zoological Nomenclature, and allows valid publication of new nomenclatural acts in electronic-only journals as well as electronic-first works. The amendment requires electronic-only, and electronic-first works to be registered in ZooBank, and to include the registration number ('ZooBank LSID') in the publication. Although registration of the names and nomenclatural acts themselves is not yet required for their availability, the amendment encourages authors to register all new names and nomenclatural acts, whether they are introduced in e-only publications or in standard paper publications as well as publications, names and acts that have been previously published. This paper provides a practical instruction manual in Japanese to assist taxonomists to register their work in ZooBank based on its new version 3.1.

The class Monogenea (Platyhelminthes) is commonly parasitic on or in aquatic or amphibious vertebrates, mainly fishes, but rarely on aquatic invertebrates. In Japan, a total of 240 nominal species of monogeneans has so far been reported. Freshwater fishes are mainly parasitized by monopisthocotyleans. Based on the number of monogenean species collected by me from Japanese freshwater fishes, 600 to 900 species of freshwater monogeneans may be found on approximately 500 species of freshwater fishes. However, only about 80 monogenean species have been reported to date. And, in total, 15 alien monopisthocotylean species have been reported from alien freshwater fishes in Japan. Monogeneans can establish more readily together with their hosts than other groups of parasites because of their simple life cycle, and some of monogeneans, especially alien species, are known to cause negative impacts on wild and farmed fish stocks. The fauna of alien monogeneans in Japan should be urgently clarified. Only 12 species of monogeneans have been reported from six of the 90 endangered freshwater fish species. It is highly desirable to clarify the monogenean fauna of the freshwater fishes on the verge of co-extinction and to conserve biological diversity of monogenean species.

Dactylogyrus oryziasi n. sp. (Monogenea: Dactylogyridae) is described from the gills of the southern medaka Oryzias latipes (Temminck and Schlegel, 1846) (Beloniformes: Adrianichthyidae) collected from an irrigation canal, Tokushima city, Tokushima Prefecture, Shikoku, Japan. This new species resembles Dactylogyrus rysavyi Ergens, 1970 in having a coiled penis passing through a tube of an accessory piece associated with a sigmoid rod, and shapes of haptoral parts, but these species differ from each other by turns of the penis and a connection point between the rod and tube of the accessory piece. This is the first record of Dactylogyrus from beloniform fish.

Value of specimens as research materials is secured by their collection information. This research attempted to restore collection information of a mammal skeletal specimen stored in the National Museum of Nature and Science with insufficient collection data by clarifying its collection history. The specimen was presented to the Tokyo Imperial Museum in 1906 from the Australian Museum, where we found the information for the specimen including the collection locality, cataloging date, collector’s name, and the catalog number of the Australian Museum. The restoration of collection information improved the value of the specimen. And the continuation of the restoration effort like this study contributes to the improvement of the global biodiversity information.

Personal computers (PCs) are now indispensable to any field of study, and it is important to master efficient ways to compose documents, analyze data, and manage literature. This is especially true of illustrations, which take much time and repeated editing prior to use in publications, posters, presentations, and so on. Although some reports exist on techniques for making digital illustrations there has been rapid progress in the development of new PC hardware and software, so that some types of previously intractable digital graphical processing methods are now feasible and even routine. In this report, we introduce an easy and efficient way to make digital illustrations based on recent progress in software development. Using as an example small arthropods, our main study subject, we demonstrate a digital illustration method implemented in Adobe^[○!R] Illustrator CS3^[○!R], and describe the use of CombineZ, a focus stacking software.

This paper reviews major results of taxonomical studies on Japanese species of harvestmen made by me over the past 40 years. The first attempt as a postgraduate student was to provide precise species identification of all-female populations of the curvipalpe-group of Leiobunum (Eupnoi: Sclerosomatidae) in Hokkaido. It was confirmed that they were Leiobunum manubriatum and L. globosum and they were facultative thelytokes showing typical patterns of geographic parthenogenesis. Leibunum manubriatum consisted of diploid populations with 2n=24 and tetraploid populations with 2n=ca. 48, while L. globosum was a tetraploid species with 2n=ca. 48. Population genomics analyses recently made revealed that L. globosum originated from tetraploid populations of L. manubriatum, thus L. manubriatum is paraphyletic. Most of the Japanese species of Opiliones having wide distributional ranges are polytypic and consist of many geographic races that intergrade one another by making hybrid zones where they meet. Some topics for those species revealed by cytogenetical analyses are briefly reviewed. They include chromosomal hybrid zones in several species, two cases of circular overlap in Gagrellula ferruginea, and B–chromosomes in Psathyropus tenuipes.
