A list of Japanese spiders (revised in 1977)

Abstract

1. This paper gives a revised, up to date list of the Japanese spiders; 914 species of 280 genera belonging to 48 families have been recorded in Japan.2. The classification follows the YAGINUMA's (1970) system with minor changes recently done.3. The followings are revised in this paper:(a) The Japanese names of three suborders.(b) Spiders of Cybaeinae are transferred from Argyronetidae to Agelenidae.(c) The genus Desis is put in an independent family Desidae.4. Compared with other family groups of spiders, Leptonetidae and Cybaeinae have been split in Japan too finely. Several genera are, therefore, combined into Leptoneta (s. lat.) and Cybaeus. Thus, Falcileptoneta, Masirana and Sarutana into Leptoneta (s. lat.), and Cybaeus (s. str.), Dolichocybaeus and Heterocybaeus into Cybaeus. And those split genera are treated as species groups.5. The many split genera of Araneus (s. lat.) shall be tentatively treated as groups until they are completely revised.
