Family Calopterygidae Selys, 1850
demoiselles
Introduction
Demoiselles or jewelwings are easily recognised by their large size, metallic colours and broad, densely veined wings. All species prefer running waters with (some) shade. About twenty genera and 185 species are known, of which only three genera and less than a tenth of the species occur in tropical Africa. [Adapted from Dijkstra & Clausnitzer 2014]
Diagnosis
Similar to Chlorocyphidae by (a) 3 or more Ax; (b) arculus halfway between base and node, or more proximal instead of distal; (c) quadrilateral with 1-9 cross-veins. However, differs by (1) face not swollen; (2) abdomen slender, reaches well beyond wing tips; (3) quadrilateral with 5-9 cross-veins. [Adapted from Dijkstra & Clausnitzer 2014]
