Key to species of Agramma from Japan

1 Median carina of pronotum indistinct on posterior process ( Figs 1A–E , 3A );costal area of hemelytron narrower than tibia; subcostal-discoidal boundary vein absent in apical part; outer and inner margins of paramere gently curved in middle part ( Figs 3B, C ); female terminalia pentagonal in ventral view ( Figs 2F, G ); posterior margin of female terminalia not protruding posteriad in middle part. ...................... A. abruptifrons Golub, 1990

Fig 1A–J. Two species of Agramma from Japan, dorsal and lateral views:A–E – A. abruptifrons Golub, 1990:A, B – macropterous female, C, D – submacropterous female, E – macropterous male with segmental oligomery of right antenna. F–J – A. japonicum (Drake, 1948): F, G – macropterous male, H, I – submacropterous male, J – submacropterous female. Scale bar = 1.0 mm.
