( Figs. 8, 9 , 20 , 27 )

Glyphipterix gemmula Diakonoff et Arita, 1976: 194 , Figs. 18, 21 . TL: Japan (Honshu); Heppner, 1982: 50; Diakonoff, 1986: 305, Pl. 14, Fig. 118 1−2; Arita and Heppner, 1992: 18, Figs. 7−8 , 60, 63.

Description. Adult with wingspan 10.0 mm. Female ( Fig. 9 ) with basal transverse streak wider than that of male ( Fig. 8 ), and its outer margin more convex.

Diagnosis. This species belongs to the gemmula -group. It resembles G. deliciosa Diakonoff, 1978 superficially, but can be distinguished by having a crescent spot above tornus, which is triangular in G. deliciosa ; the third segment of the labial palpus is longer than the median segment in G. gemmula , but equal in G. d e l i ci o s a. Moreover, the aedeagus is clavate in distal half in G. gemmula ( Fig. 20 ); while G. deliciosa has a peculiar aedeagus with distal 1/3 subconical.

Variations. A second indistinct yellow costal spot exists between the first and second costal streaks, which is absent in the description of Diakonoff (1986), but presents in Arita & Heppner (1992).
