*This entry was adjusted on January 1, 2020, following the publication of my paper in Zootaxa in 2018 on the now eight species of
Asiagomphus known from Vietnam. The original entry treated the specimens illustrated as variants of
A. auricolor. This was erroneous. They have now been published as a new species:
A. monticola.
This posting shows variations of
Asiagomphus monticola. Please see my article in Zootaxa for a full description of this species and its diagnostic characters. It is very similar to
A. auricolor, A. superciliaris and
A. xanthenatus, which are all also known from Vietnam.
