Diagnosis. The diagnostic characters are given under the previous species. The male genitalia of the species are close to those of P. venetia and P. crista sp. nov. P. g r a t a can be distinguished by the following characters: the inner process at the right angle of the dorsal process of the valva is longer than that of P. venetia , but shorter than that of P. crista sp. nov.; the ventral lobe of the valva is long and slightly acute distally, while in P. venetia it is short and truncate terminally, and rounded with a small acute dorsal process in P. crista sp. nov. The female genitalia differ from those of P. venetia and P. crista sp. nov. in the lamella antevaginalis lacks lateral triangular processes.

Biological notes. The larva and pupa were described by Hori (1927, as aerate) and Hypericum patulum (Hypericaceae) was recorded as a hostplant in Japan. The hostplant record was cited by Sato & Nakajima (1975, as hyalinata grata ).

Remarks. Parsons et al. (1999) listed three subspecies under P. hyalinata : P. hyalinata hyalinata ( Kollar, 1844) , P. hyalinata grata ( Butler, 1879) and P. hyalinata totifasciata Wehrli, 1923 . After examining the types of Ephyra grata Butler, 1879 and P. hyalinata totifasciata Wehrli, 1923 and a long series of material from China and the neighbouring regions, we find that the external and genital features of P. h y a l i n a t a are quite different from those of Ephyra grata and P. hyalinata totifasciata . Thus we restore P. hyalinata grata to specific rank and newly combine P. hyalinata totifasciata with P. grata . There are two subspecies of P. grata distributed in China, P. grata grata and P. grata totifasciata ( Peratophyga hyalinata var. totifasciata Wehrli, 1923 , Dt. ent. Z., Iris, 37: 66, pl. 1, fig. 6, 17. Syntype (s), China: Kiangsi (BMNH)). The former is distributed in Japan and the Korean Peninsula and is recorded here for the first time from Heilongjiang and Liaoning ( Figs 3–5 , 20 , 21 , 28 , 35 ); the latter is distributed in Shandong, Henan, Shaanxi, Gansu, Qinghai, Zhejiang, Jiangxi, Hunan, Fujian, Guangdong, and Guangxi ( Figs 6–8 , 22 , 29 , 36 ), and can be distinguished from the former by the smaller inner process at the angle of the dorsal process of the valva.
