Genus Platycnemis Burmeister, 1839
true featherlegs
Type species: Agrion lacteum Charpentier, 1825 [= pennipes Pallas, 1771]
Diagnosis
Pale, non-metallic damselflies with noticeably wide head. The legs have relatively long and numerous leg bristles, often widened tibiae and much white (especially males), making them feather-like in appearance in both sexes. The quadrilateral cell in all wings is almost rectangular; usually separated from subnode by two cells. Head, legs and venation are unique among North African damselflies. Details of markings are also unequaled. Coenagrionid damselflies with similar coloration have stouter heads and unexpanded, less bristly and darker legs. The anterior border of the quadrilateral cell is distinctly shorter than the posterior one, with most often three cells to subnode. [Adapted from Dijkstra & Lewington 2006]
