I would like to acknowledge the assistance given to me on the identification of these dragonflies by Matti Hämäläinen, Noppadon Makbun, Tang Hung Bun and Yong San. Any mistakes are my own as my knowledge of the Odonata is VERY limited..

The following photos are those that I have not been able to identify. Any assistance given would be very much appreciated. (The numbers relate to my filing system and should be quoted for any ID advices)
