May 10 I was checking the forest along a stream just west of Nam Bung in Yen Bai Province. I spotted a damselfly moderately high up in the shrub along a rocky outcrop. I could just about reach it. Fragile as always and sort of the same, it seemed different from Protosticta satoi, with a colorful prothorax. Under the microscope the inferior appendages are very weird and very interesting, with a large spine directed inward at the halfway point. It is very different from P. satoi. Jan van Tol described several new species for Vietnam, but this is not one of them. Does anybody have suggestions?

|Now take a look at this, appendages in dorsal view|
|And here it is, the ventral view. Now, that is weird and distinctive, I would like to suggest. If it is known, somebody is bound to recognize this.|
