Remarks

Vietnamese specimens seem to occur in two morphotypes: one with the mesosoma extensively black, metasoma from T3 onwards black, fore wing with proximal sclerite rather triangular, the conjunction between proximal and distal sclerites strong, without any constrictions; whereas the other has the mesosoma largely reddish yellow, terminal metasomal tergites entirely reddish brown to blackish, fore wing with proximal sclerite rather P-shaped, the conjunction between proximal and distal sclerites with a constriction. The slight differences in form of the proximal sclerite might be a consequence of differences in melanisation, associated with the colour differences, or could be indicative of separate species.

Distribution

Previously known from Australia, Brunei, China, India, Indonesia, Japan, Malaysia, Myanmar, and Nepal ( Yu et al. 2016). These are the first records of this species from Vietnam.
