Ricaniidae is a family of planthopper insects, containing over 400 species worldwide. The highest diversity is in tropical Africa and Asia and in Australia, with a few species occurring in the Palearctic and Neotropical realms. It is one of the smaller families in the planthopper superfamily Fulgoroidea.
Dictyopharidae is a family of planthoppers, related to the Fulgoridae. The family comprises nearly 760 species in more than 150 genera which are grouped into two subfamilies, Dictyopharinae and Orgeriinae.
Flatidae are a family of fulgoroid planthoppers. They are cosmopolitan in distribution and are distinguished from others in the superfamily by a combination of characters. Like all other planthoppers, they suck phloem sap of plants. Some species are known to communicate with vibrations through the plant stems. Communication may be with mates, or with ants that tend the nymphs, protecting them and gathering honeydew secretions. Adults of some species have brightly coloured forewings which are tougher and known as tegmina unlike the membranous hindwings which are used for flight. Although a few can be identified by their coloration, most species requires dissection and examination under a microscope with access to literature on already described species.
Issidae is a family of planthoppers described by Spinola in 1839, belonging to the order Hemiptera, suborder Auchenorrhyncha superfamily Fulgoroidea.
