Lestoideidae (Pseudolestidae, damselflies; order Odonata, suborder Zygoptera) Family of unusual damselflies, which shows many features common to other families, but whose members can be recognized by the reduced first and second anal wing vein, and from the third interculary, and fourth branch of the radius, arising midway between the arculus and subnodus in the wing. The larvae are short, with saccoid or lamellar caudal gills. There are 14 described extant species, found in the eastern Palaearctic, southeast Asia, Australasia, and Central and S. America.
