Remarks In comparison with the specimens examined by Gauld & Mitchell (1981) , Vietnamese specimens have shorter fore wings ( 10.3–12.1 mm vs 14.0–16.0 mm), shorter antennae (49–53 flagellomeres vs 54–56), and shorter SDI (1.01–1.11 vs 1.10–1.16). Distribution Previously known from Taiwan ( Yu et al. 2016 ). These are the first records of this species from Vietnam .
