Distribution.

China (Gansu, Guizhou, Henan, Hunan, Jilin, Shaanxi), Japan. New for Gansu.

Notes.

One of the most common species in China; large specimens tend to have the head less narrowed, less shiny and more sculptured in dorsal view (Figs 204 and 207 ). The length of the white or ivory apical part of the ovipositor sheath is highly variable in this species; two females from Shangluo have it up to 3.3 × as long as the hind basitarsus. The propleuron of G. oshimense is rather robust and 0.8-1.0 × as long as mesoscutum in front of tegula.
