When checking a field laid bare with some weeds near a shallow stream that dries out in winter, bordering agricultural lands, I noticed a weirdly colored Lestes. I was able to take some pictures and catch it, but afterwards I saw nearly 10 more, both males and females. Checking the literature at home it turned out to be Lestes nodalis (Selys, 1891). A species known from Thailand, Myanmar, India, and bordering China (Guangxi, Yunnan), so it is maybe not surprising it also occurs here in Vietnam, but it had not been recorded before, so another addition to the Vietnamese list!
The coloration of both the male and the female is rather peculiar, lacking the metallic shine so often seen in the genus. The appendages are very typical and the pterostigma is dark with a light border all around.

|The female is not less weird in color, maybe more so|
|Another female, note also the darker trailing edge of the slightly amber wings|
|Appendages of the male in dorsal view. Superior appendages with distally pointed projection, mostly pale yellowish with black tips.|
