Notes: Abstract: Endosymbiotic adaptations in the Coccoidea seem to have little comparative value as far as the evolutive status of main lineages is considered, because of possible convergences; however, they can be important sources of taxonomic information for the definition of larger taxa; further research needed. Keywords: symbionts.
