Issidae
Issidae is a family of planthoppers described by Spinola in 1839, belonging to the order Hemiptera, suborder Auchenorrhyncha superfamily Fulgoroidea. Distribution Species of this family are present throughout the Northern Hemisphere. Description Issidae are small insects generally with a stocky body, as the wings mainly develop in width. Basic body coloration is not striking, usually shows brownish colors. The head has two ocelli. The forewings have strong pronounced ribs. They wrap the abdomen when the insect is at rest. The family originally included approximately 1000 species with 215 genera, but the systematics of Issidae remains uncertain, with many of the subfamilies having been recently removed to separate families, including Caliscelidae. Nogodinidae, and Tropiduchidae. In 2013, scientists described a biologically unique set of mechanical gears in an '' Issus'' nymph, though identical structures are known in most planthoppers, and were known for decades before the func ...

Issus Coleoptratus
''Issus coleoptratus'' is a species of planthopper belonging to the family Issidae. Distribution and habitat This common species can be found in the western Palearctic realm, in the Near East, and in North Africa. These insects live on shrubbery and on foliage of various woody plants and common deciduous trees and in mixed forests (forest edges and parks).P.F. Whitehead & R.S. Ke/ref> Description ''Issus coleoptratus'' can reach a length of . The coloration of these planthoppers can vary from light brown and olive to nearly black. The head, including the eyes, is narrower than the pronotum. The forehead is usually dark brown to black in the upper third, with lighter spots. In the lower area it is greenish, yellowish or brownish. The leathery wings usually show a huge number of dark brown cross-veins with a dark brown discal spot and some evidence of banding. The forewing veins of males and females differs (sexual dimorphism), as they are effaced distally in the female, while i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Hysteropterum'' is a genus of planthoppers described by Amyot & Serville in 1843, belonging to the family Issidae, subfamily Issinae. Distribution Species of this genus occur in Europe and North Africa; the numerous New World species formerly assigned to this group have been reassigned to separate genera (e.g., '' Kathleenum'').

Caliscelidae
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.

Nogodinidae
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 (simple eyes) are outside the margins of the face. The face has carinae (or keels) 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. Several fossil species have been described from Eocene Baltic and Miocene Chiapas amber. Additionall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gergithus
''Gergithus'' is a genus of planthoppers in the family Issidae. Like all planthoppers, adults feed on plant sap and are capable of escaping by leaping. The genus like other members in the tribe appears somewhat rounded and beetle-like, in some cases, with a mimetic resemblance to ladybird beetles. About 60 species are known in the genus and they are distributed in the Indomalayan and Palearctic Realms. Description The genus is closely related to ''Hemisphaerius'' but differs in having longer frons (forehead) and legs. The frons also lacks a median keel (carina) or tubercles on the frons, pronotum or mesonotum. The rounded tegmen which resembles the elytra An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs ( Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes altern ... of beetles are often patterned.

Issus (planthopper)
''Issus'' is a genus of planthoppers belonging to the family Issidae of infraorder Fulgoromorpha of suborder Auchenorrhyncha of order Hemiptera. Like most members of the order Hemiptera (popularly known as the "bug" or "true bugs" order) they live on phloem sap that they extract with their piercing, sucking mouth parts. Planthoppers are the only animals known to possess a gear mechanism, and '' Issus coleoptratus'' is the first type of planthopper to have the mechanism formally described. The mesh sector gears do not transform velocity or torque, and they do not convey much of the power; they only synchronize the jumping motion of the hind legs, preventing yaw (rotation). Description The genus ''Issus'' includes small insects generally flightless with a stocky, brown body and forewings with strong pronounced ribs. They feed on phloem. Species of this genus are present in most of Europe, in the Near East, and in North Africa. Gear mechanism Planthoppers (of which th ...
