David L. Hancock & Richard A.I.Drew (New genus, species and synonyms of Asian Trypetinae (Diptera: Tephritidae). - Malaysian Journal of Sciences. - 1995. - 16A: 45-59) have already recorded this species based on 3 males and 1 female from Hong Kong Island, Taipokau, Kowloon, and Sheung Shui dist. However, the figure is poorly drawn and printed leaving an impression that the wing pattern is almost absent and the mesonotum ahving no reddish yellow vittae. However, both Shiraki's (1968) and Ito's (1984) descriptions of matsumotoi fit your specimen well.
