Five families, eleven genera and fifteen species of spiders collected from the Maritime Province, Russia are listed, and their distribution is presented. Of these, one family, five genera and ten species new to the Russian fauna and fourteen species are newly recorded from this Province. The lycosid genus Triccosta Roewer 1960 is revalidated, diagnostic figures are given for Larinioides chabarovi (Bakhvalov 1981), and the taxonomy of the family Leptonetidae and of the linyphiid genus Arcuphantes Chamberlin & Ivie 1943 in Far East Asia is discussed.
A poorly known species, Xysticus kulczynskii Wierzbicki 1902, is redescribed on the basis of material newly collected from Azerbaijan and Iran. The male is described for the first time. A diagnosis distinguishing the species from the European X. ferrugineus Menge 1876 is provided.
Although two species of the spider genus Zygiella, Z. dispar (Kulczynski 1885) and Z. montata (C. L. Koch 1834) have been recorded from Japan, I recognized only one species of the genus after the examination of many spider specimens from Japan. Judging from the figures made by Levi (1974) and the specimens from Canada, I determined the Japanese specimens as Zygiella dispar.
The genus Pseudopoda is recorded for the first time from Japan. Pseudopoda kasariana sp. nov. (_??_, _??_) and Pseudopoda spirembolus sp. nov. (_??_, _??_) are described from Amami-ôshima Island and Okinawajima Island respectively. Four new Sinopoda species are described: Sinopoda albofasciata (_??_), Sinopoda derivata (_??_, _??_), Sinopoda ogatai (_??_, _??_) and Sinopoda stellatops (_??_, _??_). Sinopoda koreana (Paik 1968) is recorded for the first time from Japan. New records of Sinopoda okinawana Jäger & Ono 2000 and S. tanikawai Jäger & Ono 2000 are presented. Within the genus Sinopoda Jäger 1999 the okinawana species-group is newly diagnosed, which is represented by S. albofasciata sp. nov. (Japan), S. derivata sp. nov. (Japan), S. fasciculata Jäger, Gao & Fei 2002 (China), S. hamata (Fox 1937) (China), S. koreana (Paik 1968) (Korea, Japan), S. okinawana Jäger & Ono 2000 (Japan), S. tanikawai Jäger & Ono 2000 (Japan), S. wangi Song & Zhu 1999 (China). Sinopoda stellata (Schenkel 1963) is deleted from the list of Japanese spiders and considered endemic to central China.
Twelve species of the mite family Phytoseiidae are reported from West Sumatra, Indonesia. Amblyseius (Amblyseius) sumatrensis sp. nov. is described and illustrated. Eleven named species are recorded for the first time in Sumatra. The male of Amblyseius (Neoseiulus) circellatus Wu & Li 1983, previously unknown, is described.
Three species of the genus Robertus are recorded from Chugoku District, Honshu, Japan. One of them, R. nojimai, is described as a new species. The other two species, R. sibiricus Eskov 1987 and R. saitoi Yoshida 1995, are newly recorded from Okayama and Tottori Prefectures.
Camisia solhoeyi Colloff is first recorded from Japan. This species can easily be distinguished from its Japanese congeners by setae h1, which are shortest of the notogastral setae. A well known species C. lapponica (Trägårdh) is very similar to C. solhoeyi, and so previous records of the former should be re-examined.
