Abstract

Five new species of the spider genus Cybaeus are described from the Chugoku district, western Honshu, Japan, under the names C. hiroshimaensis, gonokawa, tsurusakii, nojimai, and okayamaensis. These species are relatively small (2.5-3.5mm in body length) and resemble each other in the general appearances, although each of them can be clearly distinguished from the other by their structures of male palp and female genitalia. Their distributions are allopatric or parapatric with each other. They can be considered as members of a single super-species or a closely related species-group.
