They are known commonly as white-legged damselflies.[https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=213442 Platycnemididae.] Fossilworks. There are over 400 species native to the Old World.Dijkstra, K. D. B., Kalkman, V. J., Dow, R. A., Stokvis, F. R., & Van Tol, J. (2014).

The family is divided into several subfamilies.
