Euphaeidae
The Euphaeidae are a family of damselflies in the order Odonata sometimes called Epallaginidae. They are commonly known as gossamerwings. It is a small family of damselflies with around 70 species. They commonly occur in Old World tropics. They are large and mostly metallic-coloured. They look similar to species of damselflies in the family Calopterygidae. The larvae have seven pairs of supplementary gills along the abdomen in addition to the usual three sac like gills at the tip of the abdomen. Adults have the fore and hind wings of equal length, barely petiolate and a long pterostigma that is broader in hind wing. Adults have close veins, numerous antenodals (15-38) and most breed in forest streams. ==References==
