Abstract

Mainland Hokkaido (area 77,983.90 sq km) is the northernmost of the four main islands comprising Japan and is known to have a very different fauna than the other three main islands (e.g., Masuda 1999). Nine species of Polydesmida (Diplopoda) have been recorded from mainland Hokkaido: Epanerchodus acer Takakuwa, 1954, E. fontium Verhoeff, 1940, E. furculiger Verhoeff, 1937, E. gracilis Takakuwa, 1954, E. orientalis ( Attems, 1901), E. tremorum Verhoeff, 1940, Levizonus montanus (Takakuwa, 1941), L. takakuwai (Verhoeff, 1941), and Oxidus gracilis (C. L. Koch, 1847) (Takashima & Haga 1956, Miyosi 1959, Murakami 1972, Nishikawa & Murakami 1994). Here, we report new records of Parafontaria laminata (Attems, 1909) (Xystodesmidae) and Niponia nodulosa Verhoeff, 1931 (Cryptodesmidae) from Hokkaido, Japan, both representing northward extensions of the known distributions. Collected specimens were preserved in 70% ethanol. Identification was carried out using a stereomicroscope, and the whole body and gonopods were photographed using a mirrorless camera (E-M1, Olympus). Body length (BL), head width (HW), and metatergal width of the 10th segment (MTW) were measured. Voucher specimens are deposited in the Natural History Museum and Institute, Chiba (CBM), Japan.

日本北海道千足虫Parafontaria laminata的新记录（Attems，1909）（Polydesmida：Xystodesmidae）和Niponia nodulosa Verhoeff，1931（Polydeshida：Cryptodesmidae）

北海道大陆（面积77983.90平方公里）是日本四个主要岛屿中最北端的一个，已知其动物群与其他三个主要岛屿截然不同（例如，增田岛，1999年）。北海道大陆记录了9种多足目（双足目）：Epanerchodus acer Takakuwa，1954，E.fontium Verhoeff，1940，E.furculiger Verhoeff，1937，E.gracilis Takakuw，1954，E.orientalis（Attems，1901），E.tremrum Verhoeffs，1940，Levizonus montanus。Koch，1847年）（高岛和夏1956年，Miyosi 1959年，Murakami 1972年，Nishikawa和Murakami 1994年）。在这里，我们报道了来自日本北海道的Parafontaria laminata（Attems，1909）（Xystodesmidae）和Niponia nodulosa Verhoeff，1931（Cryptodesmidae）的新记录，这两个记录都代表了已知分布的向北延伸。采集的标本保存在70%乙醇中。使用立体显微镜进行鉴定，并使用无反光镜相机（E-M1，Olympus）拍摄全身和蜥脚类动物。测量第10节段的体长（BL）、头宽（HW）和中间节段宽度（MTW）。凭证标本存放于日本千叶自然历史博物馆和研究所。

期刊介绍： The Pan-Pacific Entomologist (ISSN 0031-0603) is published quarterly (January, April, July and October) by the Pacific Coast Entomological Society, in cooperation with the California Academy of Sciences. The journal serves as a refereed publication outlet and accepts manuscripts on all aspects of the biosystematics of insects and closely related arthropods, especially articles dealing with their taxonomy, biology, behavior, ecology, life history, biogeography and distribution. Membership in the Pacific Coast Entomological Society includes subscription to The Pan-Pacific Entomologist, and Society Proceedings typically appear in the October issue of each volume.
