Matsumuraeses Issiki, 1957

Matsumuraeses Issiki, 1957: 57 . Type species: Semasia phaseoli Matsumura, 1900 , by original designation.

Matsumuraeses is characterized by the following characters: forewing with chorda originating between R1 and R2 (closer to R1) and extending to between R5 and M1, and the median stem fully developed; hindwing with M3 and CuA1 short-stalked; socii in the male genitalia either surrounded by two hoodlike walls laterally (azukivora -group) and with short hairs, or fused and with long hairs; cucullus large and well-defined ( phaseoli -group) ( Razowski & Yasuda, 1975); and the ductus bursae in the female genitalia slender, usually sinuate. Matsumuraeses can be differentiated from other Grapholitini by the forewing elongate subtriangular, with a blackish spot at outer margin of discal cell and a dark suffusion at base; two pairs of scale tufts on T7 (and occasionally on S7) directed caudally; the valva strongly bent between the sacculus and cucullus, forming a neck in the male genitalia; the lamella postvaginalis either with the anterior margin smooth (azukivora - group) or having two small sclerotized processes ( phaseoli -group) in the female genitalia.
