Coenagrionoidea
A female Great -tailed Damselfly ( Ischnura elegans ) from the family Coenagrionidae.
The Coenagrionoidea form a superfamily within the suborder of damselflies ( Zygoptera ). This superfamily is associated with a variety of styles all shapes and sizes, including both the smallest and the largest known damselflies.
Features
Front and rear wings are, as with all damselflies, more or less the same. The stalked the thorax accreting wings are generally unstained. There are always two Antenodalqueradern before the nodus. The Postnodalqueradern pass into the wing in its width by pulling, cross veins in most species.
Dissemination
Representatives of Coenagrionoidea are distributed worldwide. In Europe, of the families of the Slender Dragonflies ( Coenagrionidae ) and the spring Dragonflies ( Platycnemididae ) are represented. The latter can be recognized by the broadening of the tibiae of the middle and posterior pairs of legs. This feature is found in varying degrees in all males and some females this limited to the Old World family. The otherwise very similar, species-rich and globally distributed family of Coenagrionidae this feature does not own.
The more representative of the Coenagrionoidea can be found mostly in tropical rain forests. Representative of the family of Isostictidae are confined to Australasia, their representatives are very slim with very narrow wings. The Platystictidae have conspicuously long and thin abdomen and short wings, they are found in tropical rain forests of Central and South America and East Asia. The very species and varied family Protoneuridae occurs in tropical forests throughout the world. The Pseudostigmatidae family is restricted to rainforests of Central and South America, it contains the largest known representative of the dragonfly with a body length of up to 21 centimeters.
