What is "lestoideidae"

Lestoideidae is a monotypic family of damselflies. The only genus in the family is Lestoidea, it comprises four species. The family is endemic to the streams in rainforests of north east Queensland. Lestoideidae is an accepted family name but it is important to distinguish genus Lestoidea from superfamily Lestoidea. They have the same spelling, but the superfamily is based on the genus Lestes. The taxonomic history of Lestoidea is complex because its member species show features that might suggest a position in either Lestoidea (superfamily), or perhaps with family Diphlebiidae.
