"The three new Cephalaeschna species are found nowhere else in the world but central China," Zhang Haomiao, an aquatic animal researcher from the Chinese Academy of Sciences, was quoted as saying by Xinhua.
He said the species can be "used" to monitor water quality, as they live only in the relatively pristine streams and cannot tolerate polluted water.
The dragonflies also do not like sunshine and only become active after dusk, he said.
The scientists' findings have been published in the International Journal of Odontology.
