The biology of Nymphonella tapetis Ohshima, 1927, a pycnogonid endoparasitic on some bivalves, is reviewed. After the first discovery of this species from Hakata Bay, Fukuoka in 1926, there were scattered records of N. tapetis from several places in Japan before 2007, but they were on a small scale. In April 2007, N. tapetis appeared suddenly in the commercial bivalve, Ruditapes philippinarum and several other bivalves on the Banzu Tidal Flat in Tokyo Bay. The spread of the parasite was explosive, and caused a mass mortality of the bivalves in the area. Adults of the pycnogonid live freely on or just under the surface of sandy bottoms, and show nocturnal activity. The hatching larva is a typical protonymphon larva. The larva enters the host bivalve, attaches to various soft parts, and feeds on the body fluid of the host. The number of parasites in one host ranges from one to over 60. At least eight different developmental stages can be distinguished in the parasitic larvae and juveniles. Adults leave the host probably just after the maturation molt. The adult male receives one egg-mass onto his ovigers after each mating, and one male can bear up to seven egg-masses. Several experiments were undertaken to attempt to eradicate or reduce the number of N. tapetis, but no effective method has yet been found. Three species of the genus Nymphonella have been described from Japan, the Mediterranean, and southern Africa. They are very similar in morphology, which leads to potential taxonomic confusion.

Specimens of scyllarine species (Decapoda: Scyllaridae: Scyllarinae) were collected using commercial bottom trawl nets from several sites with 50-100 m depths in the shelf water region of the Enshu-nada sea and Tosa Bay along the Pacific coast of Honshu, central Japan. Of these, Bathyarctus chani Hoithuis, 2002 and B. formosasus (Chan and Yu, 1992) are recorded for the first time from Japan while Eduarctus martensii (Preffer, 1881) and Galearctus timidus (Hoithuis, 1960) are poorly known from Japanese waters previously.

Echinoderes ohtsukai sp. nov. is described from an intertidal flat in the Seto Inland Sea, Japan, based on observations with light and scanning electron microscopy. Echinoderes ohtsukai is characterized by 1) a short middorsal spine on segment 4; 2) lateroventral tubules on segments 5 and 8; 3) short laterodorsal tubules on segment 10; 4) a trunk 315-395μm long; 5) a lack of lateral terminal accessory spines in both sexes; and 6) lateral terminal spines of about 50% trunk length. The species has modified type-II glandular cell outlets, which have previously been reported among congeners only in E. rex Lundbye, Rho and Sorensen, 2011 from the Korea Strait.

Misaki Marine Biological Station School of Science, The University of Tokyo which is located on the tip of southwestern Miura Peninsula, Kanagawa Pref. have been actively used as a base for research on Zoology for many years in broad fields, such as development biology, cell biology, molecular biology and systematic zoology. Although technical staffs have greatly supported many scientists, their contribution to the research activity almost remains unknown. In this paper, I describe variety of works that technical staffs of MMBS engage, and a part of research work we are performing.

本研究は日本大学学術助成による総合研究(代表者、鈴木實)の一環としてなされ、鈴木教授に同行した寺内により採集された材料を大久保が固定したものである。約50のサンプル瓶のうち,1/3に介形類が見られた.新種2種をふくむ11種を同定した.淡水産介形類の大部分を占める匍匐型の種はこのサンプルには種数・個体数ともに少なく,遊泳型の種は個体数が多かった.これが南西諸島の介形類ファウナの特異性によるのか,採集法の違いによるのかは,今後の研究に待たねばならない.新種Ilyocypris haterumensisおよびPotamocypris sudzukiiは,沖縄本島や奄美諸島の淡水産介形類を調査し20種を採集したBROODBAKKER(1987)の報告にも載っていないので,南西諸島の中でも南の方に生息する種と考えられる.

日本産間隙員形虫類の分類学的研究の第一報として,北海道東部太平洋岸の釧路付近の砂浜潮間帯より得られた間隙貝形虫1種を新種Microloxoconcha kushiroensisとして報告した.この属の種類の報告は,日本からは初めてであり,同時に亜寒帯からも初めてである.本種は左右に偏平で,雄の体長は約0.2mmで,雌(約0.18mm)よりもやや大きい.この種は主に付属肢の形態で同属の他の種と識別出来るが,ハワイ産のM.subterranea GOTTWALD,1983と殼及び付属肢両者の全般的な形態において非常に似ているのが特徴である.雌雄の生殖器官の形態においても両種は互いによく似ている.

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.

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 Parapodisma setouchiensis group (Catantopidae) is revised based on geographic variation in external morphology. This group appears to constitute a single polytypic species, P. setouchiensis Inoue, consisting of four geographic forms (Basic, Mt. Hyonosen, Tanba, and Yamato). Four taxa, Parapodisma tanba, P. yamato, P. hyonosenensis hyonosenensis, and P. hyonosenensis kibi, are treated as junior synonyms of P. setouchiensis. The polarity of character states in the P. setouchiensis group was inferred from the distribution pattern of the geographic forms. All pairs of adjacent forms intergrade through relatively narrow zones that may have originated from secondary contact. In two genital characters (triangular marking and cercus morphology), there are clines with different ranges across the boundary between the Tanba and Mt. Hyonosen forms.

A new genus, Idatenopsocus, represented by Idatenopsocus orientalis (Vishnyakova, 1986), comb, nov., is described and the species is redescribed. Within the family Mesopsocidae, this new genus is considered as the sister group of a monophyletic group composed of the genera Mesopsocus, Microtrichipsocus, Metapsocus, Cyrtopsochus, Hexacyrtoma, and Rhinopsocus.
