The mutualistic interspecific relationships of trophobiosis between trophobiont planthoppers (Hemiptera, Fulgoromorpha) providing food to the host called xenobiont, are reviewed. The degree of interspecific relationships between these symbionts varies from occasional or short time duration (a few hours to a few days) to longer ones, with trophobion...

The wrinkled ambient vein (appendix) on the fore wing is given as an apomorphic character for the Fulgoromorpha for which the Pennsylvanian, Moscovian genus Aviorrhyncha (310 Mya), Aviorrhynchidae, is the oldest representative to date. All other planthopper taxa belong t...

As concepts, taxa should be addressed through their name, their description (definition by intension) or their content (definition by extension). Each part of this taxonomic triplet is necessary but none alone sufficient to fully formalize a taxon without ambiguity. However, in practice, taxa are most often only addressed through their name and the...
