Lestoideidae is an accepted family name and until recently it was considered to be monotypic with only one genus, Lestoidea. However, research over the last twenty years or so has suggested that the genus Diphlebia is also part of Lestoideidae.[4][3]
Note: It is important to distinguish the genus Lestoidea from the superfamily Lestoidea. They have the same spelling, but the superfamily is based on the genus Lestes.
