Genera in orange are under revision and are not yet included in the key to genera and no key to species or fact sheets have been included for these genera. The genera can be identified through the genera key page. For each genus there will be a fact sheet to the genus, fact sheets to the species (this part is under construction and all are not yet included; if there is only one species in the genus then this species is treated on the fact sheet for the genus), a key to the species (only if there are more than one species in the genus), habitus illustrations (if there is only one habitus illustration for the genus then this is found on the fact sheet for the genus). The habitus illustrations have been drawn by Christer Hansson.
