Pouillonphlebia burmitica gen. et sp. nov., second genus and species of the mid-Cretaceous damsel-dragonfly family Burmaphlebiidae, is described from the Burmese amber. This discovery suggests that this family diversified during the Early Cretaceous in the ‘Burmese’ island that detached earlier from Gondwana and was isolated in the Tethys Ocean at that time. We also described from the same piece of amber a small ‘Psocoptera’ Burmacompsocus pouilloni sp. nov., third species of this compsocid genus, only known from this amber. This discovery confirms that the Compsocidae were certainly much more diverse during the Cretaceous than nowadays.
