Female genitalia (Fig. 23 ). Papillae anales flattened, foot-shaped, covered with dense hairs on surface. Postvaginal plate flattened, strongly sclerotised. Apophysis anterioris highly modified, short, tongue-shaped; apophysis posterioris long and slender, c. 3 × length of apophysis anterioris. Ductus bursae long, membranous, not spiral-shaped. Corpus bursae pear-shaped, twisted in its apical part, with a strongly sclerotised, nearly elliptical central signum.

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.
