Eight specimens of a scolopendromorph centipede collected in Tokashiki Island and Minamidaito Island (both in the Ryukyu Islands, Japan) represent the first record of Cryptops (Cryptops) navis Chamberlin, 1930 from the islands of the Far East (i.e., Japanese Archipelago, Ryukyu Islands and Taiwan). This material also provides new details of the morphological variability of C. (C.) navis and the first data on natural habitats of C. (C.) navis, which previously was known only from soil samples from Singapore and China.

The Japanese Archipelago

The epigean spiders of the genus Cybaeus L. Koch, 1868 are known to have diversified in western North America and the Japanese Archipelago. To date, ~80 species of Cybaeus are known from Japan, but they have not previously been recorded from the Ryukyu Islands that harbour a diversity of endemic species. Here we describe eight new species of Cybaeus from the Ryukyu Islands, extending the range of Cybaeus southward to the central Ryukyus. Both sexes of each of the new species are described, and their phylogenetic relationships are estimated using nuclear and mitochondrial gene markers. Although Cybaeus okumurai, sp. nov. and C. kumadori, sp. nov. possess genital features that are common in the other Japanese congeners, the other six species (C. yakushimensis, sp. nov., C. kodama, sp. nov., C. amamiensis, sp. nov., C. aikana, sp. nov., C. tokunoshimensis, sp. nov., and C. hikidai, sp. nov.) are characterised by an elongated embolus and tubular spermathecae. These unique genital characteristics and the phylogeny recovered here suggest that these features evolved independently among the Japanese and Ryukyu Cybaeus species. Phylogenetic analyses highlight an unusual biogeographical pattern in which C. yakushimensis and C. kodama endemic to Yakushima Island in the northern Ryukyus are related to species distributed in the central Ryukyus. In contrast, our phylogeny suggests that C. okumurai from Tanegashima Island in the northern Ryukyus is sister to C. ashikitaensis (Komatsu, 1968), distributed in Kyushu of the Japanese Archipelago. The retreat constructs and sympatric distribution of Cybaeus found among the Ryukyus are also briefly discussed. ZooBank: urn:lsid:zoobank.org:pub:640D15AA-17F4-48EE-88B4-485CFF8FCD60

A new mitten crab species of the genus Eriocheir De Haan, 1835, E. ogasawaraensis n. sp., is described from the Ogasawara Islands, Japan. It is morphologically most similar to E. japonica (De Haan, 1835), found on the Japanese mainland, the Ryukyu Islands, Taiwan, the Russian Far East, Korea and China, but diagnostic is the proportionately broader and dorsally flattened carapace which usually lacks the fourth anterolateral tooth, the ornamentation of the epistome, the male first gonopod and its the coloration. The biology of the new species and the different interpretations concerning the systematics of Eriocheir are briefly discussed.

Two New Species

Three species of nematodes were collected from some Malayan frogs and toads. Two of these are bursate nematodes, one of which belongs to a new genus for which the nameBatrachostrongylusgen. nov. is proposed. The genusBatrachostrongylushas structural features of both the families Strongylidae and Trichostrongylidae. The other bursate nematode, namelyOswaldocruzia hoeppliiHsu is widely distributed in the Far East and this is the first record from the Malaysian region. This species shows considerable variation throughout its range. Another new species,Abbreviata bufonissp. nov. is from Bufo asper Boulenger. Although the larval form ofAbbreviata ranae(Walton), the only representative of the genus in Amphibia has been recorded from U.S.A., this is the first record of an adultAbbreviataparasitic in Amphibia.

Two species of anophthalmous, unpigmentedasellids have been found in springs and groundwaters of S.E. Siberia (Primorye region). Asellus (Asellus) primoryensis n. sp. is closelyrelated to the epigean species A. (A.) hilgendorfii Bovallius, 1886, as is the case for all stygobiont Asellus (Asellus) species previously known from the Japanese archipelago. Sibirasellus parpurae n. g., n. sp. is closely related to the microphthalmous species Asellus dentifer Birstein & Levanidov, 1952 from the Ussuri Basin (Khor region), now type-species of the new genus Sibirasellus. These two species show several original characters: body covered by numerous cuticular squamulae, mandibular palp reduced (glabrous and 2-segmented), and coxopodites of pereopods reduced and coalescent with their sternites, pointing to certain affinities with the stygobiont Japanese genus Nipponasellus Matsumoto, 1962 and probably to the epigean species of the “latifrons” group of the genus Asellus, presently restricted to arctic Siberia and western Alaska. The different asellid lines living in the Far East and Pacific North America are much more related with each other than with all other lines of the family.All these forms possess a copulatory system built on the “Asellus pattern”: Endopodite of 2nd male pleopod with a spur-shaped basal apophysis or “processus calcariformis”, an afferent spermaticopening with a labial spur or “processus cylindriformis”, and 2nd exopodite segment with a tergal or “catch lobe”. This phyletic system includes the genus Asellus Geoffroy, 1762 (the present status of which is discussed herein), its subgenera Asellus Dudich, 1925, Mesoasellus Birstein, 1951, and Phreatoasellus Matsumoto, 1962, and its related genera Calasellus Bowman, 1981, Nipponasellus Matsumoto, 1962, Uenasellus Matsumoto, 1962, and Sibirasellus n. g.

In this study, molluscan shells housed at the University Museum, the University of Tokyo, provided a new set of region-specific correction values (ΔR) for the western Pacific, in particular for the central part of the main islands in the Japanese Archipelago and the southwest islands of Japan. The values of 40 total samples were calculated from 11 regions. North of the main islands and in the Ryukyu Islands, the mean ΔR values showed comparatively small values, 5–40 14C yr; in the central part of the main islands, these values were 60–90 14C yr.

AbstractThe Ryukyu (Okinawa) Islands are situated in sub-tropical zone between the Japanese Archipelago and Taiwan. Although Okinawan people have a rich tradition of star lore, few studies have been undertaken on its relevance to subsistence, religion and the socio-political system. This paper is a first attempt to explore a systematic relationship between star lore (e.g. relating to the Pleiades) with agriculture, fishing, navigation and religious practice. This paper also considers the possibility of interpreting the nature of prehistoric and historical stone structures from the viewpoint of archaeoastronomy. This kind of analysis is likely to be fruitful, since the kingship of the Ryukyu Islands was strongly associated with sun worship.

This work analyzes the seasonal development of some representatives of the genus Acer L. growing inthe arboretum of the Botanical Garden of Moscow State University. M. V. Lomonosov. Of the 23 taxa studied, therepresentatives of the genus are distinguished by the greatest adaptability to the temperate continental climate of CentralRussia, having negative indicators of the atypicality coefficient with values from – 1,14 to – 0,15. Plants of this groupmainly have natural habitats in the temperate regions of the Far East, Central Asia, Europe, and North America. The leastadapted species have FA indices from 1,08 to 1,11, growing in the Eastern Transcaucasia , Iran, Japan.
