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.

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.

Recent taxonomic and phylogeographic studies of various terrestrial organisms in the Chugoku Mountains, western Honshu, Japan, have revealed a number of remarkable geographic differentiations among populations in the mountainous regions. Interestingly, geographical boundaries of those differentiations tend to occur intensively in three areas: 1) Sendai River (eastern part of Tottori Prefecture), 2) Asahi River (Okayama Pref.) and Hino River (western part of Tottori Pref.), 3) Ota River (western part of Hiroshima Pref.) and Takatsu River (western part of Shimane Pref.). Each of these river systems has worked as a geographical barrier that facilitates genetic differentiation among the populations or as a barrier to block dispersal of populations that had already differentiated elsewhere. The current paper reviews various examples of geographic differentiations of terrestrial animals, especially harvestmen and other arthropods, in the Chugoku Mountains and discusses possible factors inducing these population differentiations.

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.

A single specimen (166.0 mm standard length) of Peristedion riversandersoni (Alcock, 1894) (Teleostei: Peristediidae), previously recorded in Japanese waters from off Toyama Prefecture in the Sea of Japan, the Pacific coast from Ibaraki to Miyazaki prefectures, and the East China Sea, was recently collected from off Iwate Prefecture, northern Japan. This specimen representing the northernmost record for P. riversandersoni is described herein. In addition, coloration of fresh and preserved specimens of P. riversandersoni are emphasized as newly recognized diagnostic characters for this species based on a comparative examination of 29 specimens of P. riversandersoni, including the Iwate specimen, with 70 specimens of Peristedion orientale Temminck and Schlegel, 1843.

Chaetonotids (Gastrotricha) are small 60-400μm in length, inhabit both the freshwater and marine environments. Their bodies are tenpin- or bottle- like shaped; flattened ventrally and arched dorsally. The sensory organs, brain, and pharynx are located in the anterior head. Posteriorly, a "furca" bears the adhesive organ. The locomotory cilia are restricted to the ventral surface, forming a pair of ciliary bands. The body wall is usually composed of the external cuticle of a flexible proteinous layer. In some gastrotrichs, the basal layer is locally thickened and specialized to form scales, spines, and hooks. The cuticular scales vary in arrangement and shape, depending on the species. The most common species are freshwater chaetonotid species that inhabit ponds, swamp, streams, and lakes. In these species male is entirely absent, thus the most chaetotonids reproduce by parthenogenesis. About 700 species of chaetonotids have been reported so far around the world. In Japan, 34 species were recorded from lakes, ponds, and swamps. Recently, 44 species have been found in the rice paddies. In this paper the natural history and diversity of chaetonotids are reviewed.

Collembola, also called springtails, are wingless microarthropods that are widespread in terrestrial habitats and mainly inhabit soil. Applications of collembolan DNA barcoding are expected in taxonomy, ecology, and environmental sciences to unveil cryptic diversity, to provide a rapid and easy method for community measurements, and to provide an accurate identification method for ecotoxicological test species for non-taxonomists. Collembolan DNA barcoding was initiated in 2004 with Canadian specimens and is now ongoing in several countries. A rapid method for non-destructive DNA extraction from individual specimens has been developed to preserve voucher specimens. A quantitative protocol for Collembola DNA metabarcoding has also been developed. Collembolan DNA barcode data are gradually accumulating, although data on type specimens and topotypes are still scarce. Because several cryptic lineages have been found through DNA barcoding, taxonomists who can classify cryptic lineages and describe cryptic species are needed.

Taxonomy is recognized as an important infrastructure of biodiversity research and nature conservation. However, taxonomy itself has been declining in terms of number of taxonomists and expertise covering various taxonomic groups. The animal taxonomy in Japan is not an exception. How can animal taxonomists improve this situation? This paper provides several suggestions including basic assessments on animal taxonomy in Japan (e.g., number of taxonomists and number of specialists on various animal taxa), making a nation-wide list of animals in Japan, research projects by groups of different specialists covering different animal taxa, and using biodiversity databases to implement new researches on distribution and phylogeography.

The taxonomy of Japanese moles, genus Mogera, has been confused since the early 1990s, because of the poorly defined type locality of M. wogura and morphological variability within the genus. Genetic research in recent decades has clarified the taxonomic problems of Japanese moles. This paper uses Japanese moles to discuss the importance of karyological study in mammal species recognition. Chromosomal rearrangements are considered likely to have an important role in species diversification of Japanese moles, resulting from postmating isolation mechanisms induced by abnormal meiosis in heterozygotic hybrids. It is well known that recombination leads to gametes with an unbalanced complement of chromosomal segments in inversion or reciprocal translocation heterozygotes. In the case of Japanese moles, four species of Japanese moles, M. etigo, M. imaizumii, M. tokudae and M. wogura, each have a distinct karyotype and/or morphological traits, and are thus considered to be full species endemic to Honshu, Shikoku and Kyushu.
