  • Taxonomic Revision of the Longiscapus-Group of Arcuphantes
    Acta arachnol., 44 (2) : 129-152, December 30, 1995 Taxonomic Revision of the longiscapus-group of Arcuphantes (Araneae: Linyphiidae) in Western Japan, with a Note on the Concurrent Diversification of Copulatory Organs between Males and Females Yoh IHARA 1 井 原 庸1):西 日本 の ナ ガ エヤ ミサ ラグモ種 群 の分類 学的 改訂 お よび雌雄 の交尾 器 官の協 同的 多様 化 Abstract The longiscapus group in the genus Arcuphantes (Linyphiidae) is revised based on genital morphology and geographic distributional pattern. This group should be treated as a closely related species group or a single superspecies by their morphology and distribution. Three known species, A, longiscapus, A. hibanus and A. iharai, and five new species, A. saitoi, A. setouchi, A. tsurusakii, A. nojimai and A. okiensis are described. These eight species are only distributed in western Honshu, northeastern Shikoku and some adjacent islands, Japan. It gives para- patric pattern to the distribution except for some cases of narrow overlap. Mor- phological correspondence between male palp and epigynum was found as a species- specific character. Twenty species of the genus Arcuphantes (Linyphiidae) have been described from various areas of Japan. However, their taxonomy is still far from complete, and there are many undescribed species even in the main islands of Japan. What makes the taxonomy more complicated is the remarkable geographic differentiation in their copulatory organs exhibited by the species of the genus. In this paper, I deal with eight species of the genus Arcuphantes (longiscapus, hibanus, iharai and five new species), which are closely related to each other, from western Honshu, Shikoku and some adjacent islands, Japan.

  • Miocene Shallow Marine Molluscs from the Hokutan Group in the Tajima Area, Hyôgo Prefecture, Southwest Japan
    Bulletin of the Mizunami Fossil Museum, no. 37, p. 51–113, 9 pls., 2 fi gs., 1 table. © 2011, Mizunami Fossil Museum Miocene shallow marine molluscs from the Hokutan Group in the Tajima area, Hyôgo Prefecture, southwest Japan Takashi Matsubara Division of Natural History, Museum of Nature and Human Activities, Hyogo, 6 Yayoigaoka, Sanda 669-1546, Japan <[email protected]> Abstract A taxonomical study of molluscs from the Miocene Hokutan Group was carried out and their paleobiogeographic implication was discussed. A total of 100 species, including 45 species of Gastropoda, 54 species of Bivalvia, and one species of Scaphopoda, were discriminated. The fauna is referred to the Kadonosawa Fauna s.s. on the basis of the occurrences of the intertidal “Arcid-Potamid Fauna” and the upper sublittoral Dosinia-Anadara Assemblage. The upper sublittoral assemblages include Turritella (Turritella) kiiensis Yokoyama, Turritella (Hataiella) yoshidai Kotaka, T. (Kurosioia) neiensis Ida, Ostrea sunakozakaensis (Ogasawara), Cucullaea (Cucullaea) toyamaensis Tsuda, Siphonalia osawanoensis Tsuda, and Varicospira toyamaensis (Tsuda). These species are distributed as far north as the southernmost part of northeast Honshû at that time, and their geographic distributions are identical with the Miocene mangrove swamp element. The occurrences of these species strongly support the previous paleoclimatic reconstruction of the Japanese Islands during the latest Early–earliest Middle Miocene age on the basis of the intertidal molluscan assemblages, and show that central and southwest Honshû was under the warmer marine climate than in northeast Honshû and northwards. All the species including a new cardiid, Parvicardium? mikii sp. nov., are described and/or discussed taxonomically.

Calciborite occurs as milky white aggregates up to 1 mm in diame- ter with shimazakiite, fluorite, bornite and calcite. An electron microprobe analysis of calciborite gave an em- pirical formula (Ca0.999Mn0.001Co0.001)Σ1.001B1.999O4 based on O = 4. The unit cell parameters are a = 8.373(2), b = 13.811(8), c = 5.012(4) Å. The mineral is optically biaxial (−), α = 1.594(2), β = 1.654(2), γ = 1.672(2) and −2 2Vcalc. = 56°. The Vickers microhardness is 177 kg mm (50 g load), and the Mohs hardness number is 3.5. The measured and calculated densities are 2.88(2) and 2.881 g cm−3, respectively. The calciborite from the Fuka mine was probably formed by a reaction of boron-bearing fluids with limestone at a temperature between 250 and 300 °C.

Firewood was used for cooking, charcoal was used for casting iron, and timber was necessary for building houses. Japanese people have skillfully used trees since early times. But in recent years, due to cheap imported wood and the change in the life of Japanese people, firewood and charcoal used as fuels were replaced with fossil fuels. Unlike the forests in the world, Japanese forests are not facing the danger of excessive use of wood but facing the danger of devastation due to not using wood.

In this study, we ex- amined the characteristics of agricultural production in Okayama prefecture from the viewpoint of grain, beans and po- tatoes excluding rice, wheat and barley in the long term. These are undoubtedly supposed to have a certain role in comple- menting the function as the staple food of rice and wheat, etc. Also, according to our literature investigations, researchers have not focused on this context for Okayama Prefecture by not spending enough attention in the past. Therefore, we fo- cus on these subjects in this paper by examining a historical significance. It is observed that some planting area and yield of crops have drastically reduced in Okayama prefecture.

Systematic dating of around 400 granitoids in the Japanese Islands have been made on the basis of total UO2, ThO2 and PbO contents of uraninite and anhydrous thorite using an electron microprobe analyzer (EPMA) at the National Museum of Nature and Science, Tokyo. The ages range from ca. 5 Ma to 300 Ma. From the granitoid ages, the Japanese Islands were divided into many terranes. In northern Japan, granitoids with ages of approximately 110–120 Ma occur in the Kitakami Mountains, southwest Hokkaido and eastern Abukuma Mountains, and granitoids with ages of approximately 100–110 Ma occur at the western Abukuma Mountains and its northern extension. The granitoids that are around 90–100 Ma old occur sporadically in the Japanese Islands: mainly in the Asahi Mountains, the Nikko area, northern Shikoku and northern Kyushu. In central and northern Japan, the younger Cretaceous granitoids, partly Paleogene, with an age of around 65 Ma occur along the western part of the Asahi Mountains and Tsukuba–Nikkou area.
