Glyphipterix regula Diakonoff et Arita, 1976

(Figs. 10, 28)

Glyphipterix regula Diakonoff et Arita, 1976: 202, Figs. 17, 23−24. TL: Southern Kunashir Islands; Heppner, 1982: 52; Diakonoff, 1986: 339, Pl. 17, Fig. 143.

Description. Adult (Fig. 10) with wingspan 13.0 mm.

Diagnosis. This species belongs to the japonicella -group. The termen of the forewing in this species is obliquely straight, without a notch below the apex, which can separate it from most species in this genus. Glyphipterix regula is closest to G. japonicella Zeller, 1877, but can be easily separated by the forewing having pure white costal streaks, which are pale ochreous-yellowish in G. japonicella .

Material examined. CHINA, Shaanxi Province: 1 ♀, Huoditang forest farm (33°25′N 108°27′E), Ningshan County, 1620 m, 15.vi.1987, leg. Houhun Li, genitalia slide No. LTT12180.

Distribution. China (Shaanxi), Japan, Russia.

Remarks. The ductus bursae of this species in our collection is rather short (Fig. 28), which is consistent with that from Japan (Arita 1987), but is much shorter than that in the allotype. This species is newly recorded for China.
