Distribution.

China (Hubei, Chongqing, Sichuan, Yunnan, Xizang); Thailand, Myanmar (Fig. 25).

Remarks.

Although the female adult was described in Orhant (2000), the female genitalia are described herein for the first time. In contrast to another known female of the genus, S. monosa, two distinctive features of this species can be recognised: the apophysis anterioris is highly modified, tongue-shaped; and the corpus bursae only with a single signum. However, in the female genitalia of S. monosa (Fig. 24), the apophysis anterioris is slender and the corpus bursae has a pair of signa.
