New damselfly genera in the Cretaceous Burmese amber attributable to the Platystictidae and Platycnemididae Disparoneurinae (Odonata: Zygoptera)

Two new damselfly genera and species Mesosticta burmatica and Cretadisparoneura hongi, are described from the mid Cretaceous Burmese amber. They are respectively tentatively attributed to the Platystictidae and to the Platycnemididae: Disparoneurinae. These discoveries confirm that the Zygoptera of the coenagrionomorphan clade with shortened median posterior and cubitus anterior were already rather diverse during the Early Cretaceous.
