Two new species for Xuan Son

23 November I drove to Xuan Son, yet again, in search of Planaeschna species. Sadly, the weather was not as good as hoped. It only become clear from 4 PM, way too late. But I did see some Planaeschna guentherpetersi and I also bumped into two species I had not seen at Xuan Son before. The first was Gynacantha japonica. I had seen that at Huu Lien, until now the only location in Vietnam, but evidently it is more widespread. I saw 3 flying around over a dried out muddy pond and was able to catch one. At the same location I had seen G. subinterrupta before, so it was a bit of a surprise to now catch a different species here. The other new species for the reserve was Anisopleura qingyuanensis. Not only a rather late observation, this was also interesting, because these are conspicuous insects and I have by now visited the area and the concerned stream so many times, it is truly a surprise to see it.


Very nice male Gynacantha japonica
And also very nice, male Anisopleura qingyuanensis. In fact more yellow than it looks in this picture.
