Zodariid spiders of the genera Asceua Thorell, 1887, Mallinella Strand, 1906, and Akyttara Jocque, 1987, obtained from Dambri in Lam Dong Province, southern Vietnam, are reported. Four new species are described under the names, Asceua piperata, Mallinella momoina, Mallinella dambrica and Akyttara odorocci. The holotype (female) of Asceua torquata (Simon, 1909) described from Hanoi, northern Vietnam, was re-examined and illustrated for a comparison with the new species. Both the Asceua species closely resemble each other in the shape of epigynum. Mallinella dambrica seems to be related to M. klossi (Hogg, 1922) known from Lang Biang, about 100km apart from Dambri in a northeastern direction, while M. momoina shows peculiar characters in the genus, especially those of the structure of female genitalia. The genus Akyttara was discovered in Asia for the first time.

Spider specimens of about 1,750 in all were obtained during faunal researches in the Imperial Palace of Japan, which covers an area of 1,150,000 square meters in the center of Tokyo, in the period of 2001-2005. The spiders were collected from the gardens and around moats by sweeping and beating vegetations and sifting soil litter as well as by collecting with hands. A hundred and seventeen species were determined based on this material, including twenty species newly recorded to the fauna of the Imperial Palace. At the present 165 species of spiders are known in the Palace. The number of species reveals that the gardens fill an important role in a green tract of urban area in the center of Tokyo. However, results of an analysis on the species composition show that most of the species found are tough under urban environments by nature and can move well and migrate by ballooning. The fauna in the green tract of Tokyo generally resembles those in coastal areas of Kanto District and in the volcanic islands of Izu-Shichito in the common-species rate more than 70%. Species of larger linyphiids, scare theridiids and araneids, thomisids and salticids living on low vegetation, large spiders as Argiope amoena which require restricted prey insects, and lower active species in ballooning as coelotine spiders and Sinopoda forcipata are lacking in the Palace gardens. A plan to make special biotope to revive a rich fauna and species diversity with those spiders is proposed for the future horticulture and gardening in the Imperial Palace Gardens.

北陸・山陰地域の自然史科学的総合研究の一環として, 1985年5月から6月にかけて, 能登半島および石川県南部の地域で, 葉上性クモ類の採集調査を行なった。採集地点はすべて標高900m 以下の平地あるいは低山地であり, 島嶼や高山帯は対象外とした。本調査で得られた約1,000個体のクモの標本のうち, フクログモ, ワシグモおよびカニグモ類の標本291個体を分類学的に研究した結果, フタホシテオノグモ Callilepis schuszteri, ハナナガトラフカニグモ Tmarus hanrasanensis, セマルトラフカニグモ T. rimosus, チクニエビスグモ Synaema chikunii, シナカニグモ Xysticus ephippiatus ならびにチシマカニグモ X. kurilensis の6種を同地域から初めて記録した。このうちとくに興味深いハナナガトラフカニグモとチシマカニグモについては若干の注釈を加え, 生殖器を図示した。また一新種ウエノフクログモ Clubiona uenoi を記載した。 以上の記録に先人の業績を整理して加えると, 同地域からフクログモ科13種, ワシグモ科5種, カニグモ科19種が知られることになる。しかし, 少なくともこの3科に関するかぎり, 同地域は本州中南部の低山地にみられる典型的なクモ相を呈し, 地域的特異性や地史との関連は見出せない。同地域のクモ相は北海道低地から九州まで広く分布するクモを中心に成り立っていて, 亜熱帯や寒帯, 高山性の分子を欠いている。 一般に葉上性のクモは広域分布を示すものが多く, その生息域はおもに気温や生物的環境に影響されるが, 本調査地点の緯度的および高度的条件を考慮すれば, 以上この内容はむしろ当然の結果というべきかも知れない。

A new spider of the genus Xysticus C. L. KOCH, 1835,is described from the mountainous areas of Taiwan 1,500-3,300m in elevation, under the name of Xysticus chui. At present, this is the only species of the genus recorded from the island. Though its male palp appears unique in bearing three, much developed tegular apophyses, it seems to belong to the species-group of Xysticus luctans.
