139: Nepogomphus walli (Fraser, 1924)

Number: 139 / Family: Gomphidae / Genus: Nepogomphus

Species: Nepogomphus walli

Common name(s): N/A

Habitat: Exposed but tree-lined streams

Province(s) sighted: Petchabun, Chiang Mai, Nan, Narathiwat
In flight: July-August / Sightings (by me): Uncommon

Just as I was cursing that last dragonfly flying away, another new species landed right in front of me on the tall reeds.

Again... one shot, it was off, high up into the trees. Still, at least this shot is pretty good and should be good enough for ID.

Finally, this has now been looked identified as Nepogomphus walli, through the expert eyes of Noppadon Makbun and Tom Kompier. With thanks. Since then I have seen this species on several occasions throughout Thailand

The Male

Can be easily identified through its rather gruesome yellow and black appendages and unique markings, especially the large yellow streak towards the end of the abdomen.

The 'Teneral' Male

This male was spotted early one morning at the main river that runs through Hala-Bala Wildlife Sanctuary, in Narathiwat, August 2025.

The Female

The female is similar to the male and often found close by.
