Family Lestidae Calvert, 1901
spreadwings

Introduction

About 150 species in nine genera occur worldwide, of which only one genus and about a tenth of the species are Afrotropical. [Adapted from Dijkstra & Clausnitzer 2014]

Diagnosis

This family shares the combination of (a) 2 Ax instead of 3 or more; (b) arculus halfway between base and node, or more distal; (c) quadrilateral without cross-veins with several other damselfly families but differs by (1) R4 and IR3 originate well proximal to subnode, rather than at the subnode; (2) median vein zigzags from point proximal to subnode; rather than being straighter; (3) most cross-veins not aligned with Px, venation appearing chaotic, many cells pentagonal.
