Another Pseudagrion species and the third I have now posted, is one I saw late last year at Khao Kitchakut National Park, near Chantaburi. It is, of course, Pseudagrion williamsoni. 

The male

At the large lake near the headquarters of Khao Kitchakut NP, I spent a long time looking for this species. There were many Pseudagrion microcephalum, making locating them tough. Then I saw the green face. It's unmistakeable. They are very shy and fly away at the slightest movement. Eventually, I managed to spot one that was happy in my company and I got a few photos. 

Green with envy...

I managed to capture this one and again I haven't got round to cutting those fingernails!

The female

I am 99% sure that this is the female. The black stripe on the side of the thorax is much broader than that of P. microcephalum. If I am wrong, please let me know.

I have only seen this species once and was guided there by... you guessed it, Noppdon Makbun! Thank you very much once again. I think the species is there all year round.
