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.
Acanalonia is a genus of planthopper in the fulgorid family Acanaloniidae.
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.
Nogodinidae is a family of planthoppers. They have membranous wings with delicate venation and can be confused with members of other Fulgoroid families such as the Issidae and Tropiduchidae. Some authors treat it as a subfamily of the Issidae. Some of their key features are a frons ("face") that is longer than wide and a reticulate wing venation. They are less than 2 cm long. The antenna arises well below the eye, has the base clubbed and flagellum unsegmented. The lateral ocelli are outside the margins of the face. The face has carinae on the edge. On the hind leg, the second tarsal segment has an apical spine arising from it. The tibia of the hind leg also has spines towards the tip. An important family character is found in the shape of the male genital structure, a style that is longer than broad. Most members of this family are forest species.
Caliscelidae is a family of planthoppers, sap-sucking insects that belong to the order Hemiptera, suborder Auchenorrhyncha and superfamily Fulgoroidea. They are somewhat anomalous and have often been included within the family Issidae. Studies made in 2013 of the phylogeny of the Issidae and other groups using molecular techniques support the treatment of the group as a separate family. Sexual dimorphism can be marked. Some members of the family are called piglet bugs due to the shape of their snout. A particularly aberrant genus described in 2011 from India, Formiscurra, has males that resemble ants.
Achilidae is a family of planthoppers, sometimes called "achilids" in the order Hemiptera. There are at least 520 described species in Achilidae.
Aplos is a genus of issid planthopper with only one species, Aplos simplex. Aplos simplex was formerly listed under the genus Thionia.
Thionia is a genus of planthoppers in the family Issidae. There are at least 60 described species in Thionia. However, several genera have been split off from Thionia reducing the number of species.
Tropiduchinae is a subfamily of tropiduchid planthoppers in the family Tropiduchidae.
Elicinae is a subfamily of tropiduchid planthoppers in the family Tropiduchidae, with Elica the type genus.
Acanaloniidae is a family of planthoppers. It is sometimes treated as a subfamily of Issidae.
The Hemisphaeriinae are a subfamily of bugs in the family Issidae, based on the type genus Hemisphaerius. Species in 107 genera have been recorded in most continents, but the greatest diversity appears to be in South-East Asia.
Thionia bullata is a species of issid planthopper in the family Issidae.
Cheiloceps is a genus of planthoppers in the family Issidae. Cheiloceps was described as a genus by Uhler, 1895, downgraded by Fennah, 1955 to a subgenus of Thionia; then restored to genus status by Gnezdilov, 2018.
Thioniina is a subtribe of planthoppers in the tribe Thioniini. It contains 4 genera.
Fowlerium is a genus of planthoppers in the family Issidae. They are native to the Southwestern United States and Mexico.
Fowlerium acutum is a species of planthopper in the family Issidae. They are native to central Texas and Oklahoma.
Waorania is the only genus of issid planthopper in the subtribe Waoraniina. The first two species in the genus were discovered in the forests of Ecuador.
Diceroptera is a genus of issid planthopper with one species, Diceroptera humboldti. It can be found in Venezuela.
