Acanalonia is a genus of planthopper and contains the majority of the species within the family Acanaloniidae. Species have been recorded from southern Europe and the Americas.
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.
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. It can be found in most of the Eastern United States and is now found as an invasive species in Northern Italy and Austria. 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 Hysteropterinae are a subfamily of bugs in the family Issidae, based on the type genus Hysteropterum. Species in 59 genera have been recorded in Europe, Africa, and Asia. One species, Agalmatium bilobum, is now also found as an invasive species in the United States, especially in California.
The Hemisphaeriinae are a subfamily of bugs in the family Issidae, based on the type genus Hemisphaerius. Species in 119 genera have been recorded in most continents, but the greatest diversity appears to be in South-East Asia.
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 planthopperin 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.
Notosimus is a genus of planthopper and contains the single species, Notosimus angustipennis. It is found in northern Argentina. It was initially placed in the family Issidae, however analysis of the ovipositor in female specimens led the genus to be moved to Acanaloniidae in 2012.
The Nogodininae are a sub-family of tropical planthoppers erected by Leopold Melichar in 1898. The recorded distribution is: South America, Africa and the Middle East, South and SE Asia through to Australia.
