Remarks. The female of G. yasumatsui is very similar to that of G. horvathi Kieffer in Kieffer & Marshall, 1906, from the Palaearctic. The males should solve the problem of a possible synonymy, but the male of G. yasumatsui is unknown. This problem is mainly important in Japan, where the geographic distributions of the above two species seem overlapped.
