Diagnosis. Adult ( Fig. 4 ). Wingspan 10.5−13.0 mm. This species is similar to G. vectisana (Humphreys & Westwood, 1845) superficially, but G. datetis can be distinguished by the socius abruptly narrowed at the middle and parallel-sided basally and distally, and the cornutus about 1/2 the length of the phallus in the male genitalia ( Fig. 14 ); and by the length of the antrum about 1/2 its width and the ductus bursae as long as the corpus bursae in the female genitalia ( Fig. 23 ). In G. vectisana , the basal 3/5 of the socius is parallel-sided and the distal 2/5 is gradually narrowed, and the cornutus is about 1/3 the length of the phallus in the male genitalia; the antrum is nearly as long as wide, and the ductus bursae is about 1/3 the length of the corpus bursae in the female genitalia.

Distribution. China (Anhui, Guizhou, Hebei, Henan, Shandong, Shaanxi, Tianjin), Thailand.

Remarks. This species is recorded for the first time from China. According to Diakonoff (1984), the phallus of G. d a t e t i s bears two cornuti, but we could see only one in his figure. In the specimens we examined, the phallus bears only one long, slender cornutus, and this is characteristic of Gynnidomorpha species. However, in addition to the slender cornutus there is a sclerotized plate in the vesica. Therefore, we think that Diakonoff (1984) referred to the sclerotized plate as a second cornutus in his original description of the species.

Gynnidomorpha julianiensis (Liu & Ge, 1991) ( Figs. 5 , 24 )

Phalonidia julianiensis Liu & Ge, 1991: 356. Type locality: China (Jiangxi, Mt. Jiulian). Gynnidomorpha julianiensis: Razowski, 2009: 55 . [previous combination not seen]

Material examined. CHINA: Hunan Province: 1 Ƥ, Mt. Badagong, Sangzhi County (29°23ʹN, 110°11ʹE), 1250 m, 13.viii.2001, leg. Houhun Li and Xinpu Wang. Guizhou Province: 1 Ƥ, Xiaodanjiang, Rongjiang County (25°56ʹN, 108°30ʹE), 680 m, 15−16.ix.2005, leg. Jialiang Zhang; 2 Ƥ, Kuankuoshui Nature Reserves, Suiyang County (27°58ʹN, 107°11ʹE), 1500 m, 12.viii.2010, leg. Linlin Yang. (Genitalia slide Nos.: SYH10121 Ƥ, SYH11407 Ƥ, SYH11555 Ƥ).

Diagnosis. Adult ( Fig. 5 ). Wingspan 10.0−12.0 mm. This species is very similar to G. permixtana ([Denis & Schiffermüller], 1775) superficially, but G. julianiensis can be distinguished by the ductus bursae slightly longer than the corpus bursae and the ductus seminalis arising from the anterior 2/5 of the ductus bursae in the female genitalia ( Fig. 24 ). In G. permixtana , the ductus bursae is about 1/2 the length of the corpus bursae and the ductus seminalis arises from the posterior 1/3 of the ductus bursae.

Distribution. China (Guizhou, Hunan, Jiangxi).

Remarks. The male of this species remains unknown.
