Distribution. Japan; Korea and widespread in China.

Remarks. This species was described from several specimens ( syntypes) from Japan. These types have not been examined and the identity of the species is based on the figures of Kwon & Lee (1979) and Lee (1979). This species is similar to S. grandis (Matsumura) , but it can be distinguished by the following combination of characters: smaller size; apophysis of style long, strongly laterally curved; aedeagal shaft slender, far away aedeagal base.
