A planthopper is any insect in the infraorder Fulgoromorpha, in the suborder Auchenorrhyncha, a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, planthoppers generally walk very slowly. Distributed worldwide, all members of this group are plant-feeders, though few are considered pests. Fulgoromorphs are most reliably distinguished from the other Auchenorrhyncha by two features; the bifurcate (Y-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped second segment (pedicel) that bears a fine filamentous arista.
The Cixiidae are a family of fulgoroid insects, one of many families commonly known as planthoppers, distributed worldwide and comprising more than 2,000 species from over 150 genera.
The family Derbidae is a large and diverse group of planthoppers, widely distributed in the tropics and also found in subtropical and temperate regions. It includes more than 150 genera and more than 1500 species. The adults suck the sap of plants while the nymphs live mainly in decaying organic matter, for example under the bark of dead tree trunks, feeding on fungi. In some groups of species the general structure of the insects is largely uniform, whereas in others like in the subfamily Otiocerinae various forms can be found. For example, the shape of the head, the antennae or the wings can differ considerably among genera and species.
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.
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.
Cixiinae is a planthopper subfamily in the family Cixiidae. It is one of three such subfamilies, the other two being the Bothriocerinae and the Borystheninae. While a few species had been tested in a larger study of the Fulgoroidea, neither the Cixiinae nor its tribes were analysed cladistically until 2002. Resolution of tribal relationships is incomplete and additional testing of the tribes with samples larger than one per tribe is needed.
Euterpnosia is a genus of cicada native to the island of Formosa, the Ryukyu Archipelago, Japan, Hainan and mainland Asia - China, Bhutan, Nepal and Vietnam. The type species is Euterpnosia chibensisMatsumura, 1917. Until 2013 this genus was placed in the subtribe Leptopsaltriina, but is now considered typical of the Euterpnosiina Lee, 2013.
Lophopidae is a family of fulgoroid plant-hoppers with most species found in tropical South America and Asia.
Cixiini is a planthopper tribe in the family Cixiidae. This tribe is non-monophyletic.
Melanoliarus is a genus of cixiid planthoppers in the family Cixiidae. There are at about 50 described species in Melanoliarus, which are common and widespread in the Nearctic and Neotropics.
Oeclidius is a genus of kinnarid planthoppers in the family Kinnaridae. There are at least 20 described species in Oeclidius.
Achilidae is a family of planthoppers, sometimes called "achilids" in the order Hemiptera. There are at least 520 described species in Achilidae.
Andixius is a genus of planthopper insects belonging to the family Cixiidae. The genus contains 4 species. Three species found in China, the other species from Japan.
Andixius longispinus is a species of planthopper belonging to the family Cixiidae. It is endemic to China.
Andixius trifurcus is a species of planthopper belonging to the family Cixiidae. It is endemic to Yunnan, China.
Andixius venustus is a species of planthopper belonging to the family Cixiidae. It is endemic to China.
Dictyopharinae is a subfamily of dictyopharid planthoppers in the family Dictyopharidae. There more than 100 genera and 500 described species in Dictyopharinae.
Goniagnathini is a tribe of leafhoppers in the subfamily Deltocephalinae. Goniagnathini contains 4 genera and around 60 species. Of these, one new species, Goniagnathuscornutus was recently verified in China.
Florissantia is an extinct monotypic genus of planthopper in the dictyopharid subfamily Dictyopharinae. The single species, Florissantia elegans, was described by Samuel Hubbard Scudder (1890) from fossils found in the Florissant Formation of Colorado.
