Diagnosis. Tachinus (Tachinus) bipustulatus can be distinguished from other members of the subgenus Tachinus from Japan by the combination of the following characters: elytra almost entirely black; apical end of parameres of aedeagus abruptly dilated in lateral view; inner lobes of female tergite VIII divided by shallow semisircular incision. For detailed redescription, see LI (1995a: 57).
