Abstract

The large- and medium-sized species of the genus Cybaeus are reported based on the specimens collected from the Tohoku district, northern Honshu, Japan. Four new species, Cybaeus urabandai, C. yoshida, C. sasakii and C. miyagiensis, and three known species, C. nipponicus (Uyemura 1938), C. magnus Yaginuma 1958, and C. aquilonalis Yaginuma 1958, are described. Males of C. magnus and females of C. aquilonalis are described for the first time. Four new species occur only in the Tohoku district. Cybaeus magnus and C. aquilonalis are also distributed in Hokkaido. Cybaeus nipponicus is distributed over a wide range, not only Honshu but also Shikoku and Kyushu.
