(Current placement of the valid genera in their higher family group taxa, including distribution data of the included species see below.)
The following list presents an overview of the numbers of genera and species per family, and where possible per subfamily. Subspecies have not been considered in this list. Also family-group names lower than subfamily have not been treated, because too much controversy and change affects this level. Please note that the total number of species included in all families or subfamilies does not equal the total number of known species, because a few nominal taxa –particularly for fossils– have not yet been associated with a family-group taxon.
