Another species of Burmagomphus recently published (Karube, 2014) from Vietnam and, based on its two records from Tam Dao in the north and Lam Dong in the south apparently widespread, if uncommon, is B. divaricatus. I ran into a teneral male when checking a relatively open river near Cao Bang City in Cao Bang Province on May 20. Subsequent visits did not show up other specimens, so I will have to make due with the teneral specimen for publication here.

|Female of B. asahinai. Summer 2014. Photo by James Holden. As can be seen from the cluster of eggs she was ovipositing.|
|With its distinctive thoracic pattern and divaricate appendages, this male B. divaricatus could be identified without capture, which was lucky for it, given its fragile state.|
