The faunistica lstudy of spiders in Hokkaido, the northernrnost main island of Japan, has
been poorly accomplished in comparison with that in Honshu and Kyushu. Two hundred
sixty-five species ofspiders were liste dby YAGINuMA (1977 )flr'o mHokkaido, but these may only
be about one-third ofthe estimated number ofthe species really occurring there. Besides ,most
records were rnade on the basi sof specimens collected in the central and southern parts of the
island.
With the recent progress ofthe researches made by Russian arachnologists, spiders ofvarious
familie sfrom the neighboring regions ef Hokkaido, namely Siberia .Sakhalin, Kamchatka and
the Kurile Islands ,have been studied on a reliable basis (EsKov ,1980-, TANAsEviTcH, 1987-,
MARu･slK. 1986-,OvTsHARENKo & MARuslK, 1988,ZyuzlN & MARus]K, 1989,WEsot:owsKA &

1990-, LoGuNov & MARusiK, 1990, and many others). Lying in the northeastern edge of
Eurasia, Hokkaido possesses a great significance frem the viewpoint of faunistic sand zoogeogra-
phy of spiders.
In the course of the Syntheti cResearche son the Natural Histor yof the Japanese Islands
made by the National Scienc eMuseum, Tokyo, the presen tauthors carried out a research trip to
the northernmost part of Hokkaido in July 1990 in order to collect materials for the faunistical
and zoogeographical studies ofspiders in Hokkaido. During the research, about 2,4oo individ-
uals of spiders weTe collected in various places selected. Though zoogeographical analysis has
not been sufflciently performed with these materials, some importan ttaxonomical results, includ-
ing discovery of some new species, were obtained. This puper reports these results as well as the

Materials and Methods
All the specimens used in this paper with the exception of those for comparison were
collected by the presen tauthors from 10th to 18th July 1990 in the selected areas of the
northernmost parr of Hokkaido, The collecting sites plotted on Fig. 1 are presented in the

The spiders were collected from trees ,shrubs, low herbs and leafllit tbeyr ssxN'eeping, beating
and sifting methods as well as by hand sorring. About 2,400 individuals ot' spiders were
obtained. They were preserved in 75 % ethyl alcohol and identifi eidnto the specific teve las far
However, juvenile but
as possible . not only many unidentified specimens also some adult ones
were lef tfor further taxonomical studies. CHIKuNI's publication (19g9 )was very usefu1 for

Discussion
From the present research areas (Fig .1), 91 species of spiders have hitherto been recorded
(S.SAiTo, 1933;YAGiNuMA, 19S7, 1979, 1987; AKIyAMA, 1961; YAaNuMA & OHNe, 1967;

KuMADA, 1979; HAyAsHi, 1987). Ofthese ,S9 were rediscovered (spec inaemes with asterisks in
Table 1) ,while the fo11owin g33 species were not found during the present research: Octonoba

As sho-'n in Table l ,168 species (ofthe s7e7 are new to the spider fauna ofthe northernmost
part of Hokkaido) were recognized as the results of the present research. These are the
northernmost records of distributio nof those species in Japan. Though the nurnber of the
species know'n from this area reaches a total of 200, the materials may not be sufTlcient for a
zoogeographical analysis. Ho-'ever, some noteworthy species of the families Theridiidae,
