Ba Vi National Park has more to offer

This morning we wandered around Red River Island looking for river breeding gomphids, but we did not find any. Thereafter I drove to Ba Vi to try my luck there. We still have the Drepanosticta enigma to solve. Checking the streams I ran into two new species for my list. Sinorogomphus nasutus is a species I really wanted to see and I am happy I succeeded. Thank you Sebastien for pointing the way! The other species was a Leptogomphus. Haruki Karube showed me the manuscript of his upcoming article for Tombo on Gomphids from Vietnam. In it is also Leptogomphus elegans, which allowed us to identify a Leptogomphid enigma. Sebastien had photos of the appendages of a Leptogomphid that he could not identify, but now we can. I really did not expect to see that same species at Ba Vi. A happy occasion!

Dorsal view, normally inferiors would be visible, but S10 bent downwards

Photos in the field failed, so a scan of Leptogomphus elegans, male

The same reason, the same male
