Rhyothemis pygmaea is definitely an uncommon species. For the very first time, I bumped into it in Sg Bebar, Pahang. It looks alike Rhyothemis obsolescens but with its wings lacking distinct marking as that of R. absolescens. Matti requested a photo of R. pygmaea from me to be included in the upcoming book "Photographic Guide of Dragonflies of Singapore". I have given this photo for the book. Anyway, R. pygmaea is really cute.
