Remarks

Antennae of Vietnamese specimens have 56–58 flagellomeres, slightly longer than those of specimens examined by Gauld & Mitchell (1981) (53–55 flagellomeres). Some fore wing indices of Vietnamese specimens are greater than those of specimens examined by Gauld & Mitchell (1981), such as AI = 0.83–1.0, CI = 0.2–0.43, SDI = 1.35–1.43 (vs 0.75–0.85, 0.2–0.25, 1.2–1.3, respectively), whereas ICI = 0.41–0.43, smaller in comparison to 0.44–0.59 in Gauld & Mitchell (1981).

Distribution

Previously known from China (including Taiwan), India, Japan, Philippines, and Sri Lanka (Yu et al. 2016). These are the first records of this species from Vietnam.
