Genus Lindenia de Haan, 1826
Type species: Aeschna tetraphylla Vander Linden, 1825
For an introduction to this genus, please refer to: Dijkstra, K.-D.B. & R. Lewington, 2006. Field guide to the Dragonflies of Britain and Europe. British Wildlife Publishing. 1-320.
The largest gomphid in North Africa (1-2 cm longer than Onychogomphus forcipatus), where its combination of great length (about 7-8 cm), large leaf-like flaps on S7-8 and triangles in wings crossed by veins is unique. The flaps on S7 rule out all other species. Paragomphus and Onychogomphus have flaps on S8-9 instead of S7-8, but only in Paragomphus are they similarly large. The yellow to pale-brown pterostigma is relatively large and long. Triangles in the wings are divided by cross-veins into 3-4 cells, but are single-celled in other North African gomphids. The upper appendages are finger-like and almost straight, about twice as long as S10, dwarfing the lowers. Paragomphus and Onychogomphus have strongly (down- and/or in-) curved uppers. At a glance may be mistaken for the long-bodied skimmers Orthetrum sabina and O. trinacria, which lack wide flaps and separated eyes. [Adapted from Dijkstra & Lewington 2006]
