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.

The spider genera Cybaeus (Cybaeidae) and Arcuphantes (Linyphiidae) comprise numerous species endemic to Japan. They are considered to have diverged as the result of geographic isolations, probably enhanced by their low dispersal abilities. The current paper analyses the species composition and geographic differentiation in the genera Cybaeus and Arcuphantes in western Honshu and adjacent areas. The genus Cybaeus contains species with a wide range body lengths (from ca. 3 to 15mm), with local species assemblages usually consisting of representatives of different size classes. Local species assemblages often constitute a group of closely related species, together with other similar-sized species that are allopatrically or parapatrically distributed with one another. Diversity in genital morphology and geographic differentiation patterns are discussed for species-groups of Cybaeus (C. nipponicus, C. kuramotoi-group, C. miyosii-group and C. hiroshimaensis-group) in western Japan. The kuramotoi-group, which contains species of medium size (approximately 5 to 7mm in body length), has the most diverse genital morphology and is characterized by the presence of a mating plug. The Arcuphantes longiscapus-group is composed of closely related but distinct species based on their morphology and geographical distribution. The group contains eight species that are distributed in western Honshu, northeastern Shikoku and some adjacent islands, Japan, but the distribution patterns are parapatric except for a few cases of narrow overlap. Among these species, morphology of the male palp and female epigynum was strictly speciesspecific. They operate like a lock-and-key system, so that mating is only possible between individuals of the same species.

The current financial crisis at the International Trust for Zoological Nomenclature (ITZN) is reported here in the hope of inspiring widespread participation in an urgent, earnest, and ultimately successful fund-raising effort to save it. The organization, purpose, and history of ITZN are recounted here in brief, and evidently for the first time in Japanese, to foster a wider and better understanding of its significance. ITZN financially supports the entire operation of the International Commission on Zoological Nomenclature (ICZN) and its Secretariat, whose activities are indispensable for stability in the scientific names of animals. The Commission is responding innovatively to new technical opportunities by developing tools to make nomenclature more accessible and reliable, as shown by the 2012 amendment to the Code to allow valid electric publication and the relaunch of ZooBank, the Official Registry for Zoological Nomenclature, in a new architecture and better interface, both giving rise to an impressive increase in registrations. Establishing ZooBank as a gold-standard archive of scientific names is as important a task as the related endeavors of keeping archives of type specimens (the core role of Natural History Collections) and archives of published information (the core role of libraries and online data archives). ITZN's financial underpinnings must be restored quickly, with an assurance of steady and adequate future income. The risk is such that it could fail and be dissolved as soon as 2013. If ITZN founders, ICZN's ability to function will be severely compromised. A new "subscription" campaign to encourage annual pledges of funds to ITZN from stakeholder institutions and organizations around the world (museums, learned societies, businesses, etc.), including in Japan, is outlined.
