Agalmatium is a genus of planthoppers belonging to the family Issidae, subfamily Issinae. [1]
Species within this genus include: [2]
These species are distributed in the Mediterranean, from Portugal, Morocco and Tunisia to Israel, the Crimea and the Caucasus. One species - Agalmatium bilobum – has been introduced in California (USA). [3]
These planthoppers are characterized by the first segment of hind legs (metatarsomere) with only two intermediate spines apically. In the upper part of the forehead the horizontal transverse carinae are missing. The shape of the body is compact, the head is short and wide. Wings are rather developed, elytra are quite short. Legs are short and strong. [3]
The Auchenorrhyncha suborder of the Hemiptera contains most of the familiar members of what was called the "Homoptera" – groups such as cicadas, leafhoppers, treehoppers, planthoppers, and spittlebugs. The aphids and scale insects are the other well-known "Homoptera", and they are in the suborder Sternorrhyncha.
A planthopper is any insect in the infraorder Fulgoromorpha, in the suborder Auchenorrhyncha, and 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 surprisingly few are considered pests. The infraorder contains only a single superfamily, Fulgoroidea. Fulgoroids 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.
Delphacidae is a family of planthoppers containing about 2000 species, distributed worldwide. Delphacids are separated from other "hoppers" by the prominent spur on the tibia of the hindleg.
Derbidae is a family of insects in the order Hemiptera, the true bugs. It is one of the largest and most diverse families of planthoppers. It is widely distributed around the world, especially in the tropics, and with many species in subtropical and temperate regions.
Dictyopharidae is a family of bugs in the suborder Auchenorrhyncha belonging to the infraorder Fulgoromorpha. The family comprises nearly 760 species in more than 150 genera which are grouped into two subfamilies, Dictyopharinae and Orgeriinae.
Hysteropterum is a genus of planthoppers described by Amyot & Serville in 1843, belonging to the family Issidae, subfamily Issinae.
Issidae is a family of planthoppers described by Spinola in 1839, belonging to the order Hemiptera, suborder Auchenorrhyncha superfamily Fulgoroidea.
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 they live on phloem sap that they extract with their piercing, sucking mouth parts.
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.
Issus coleoptratus is a species of planthopper belonging to the family Issidae.
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.
Falcidius is a genus of planthoppers in the family Issidae.
Kosswigianella is a genus of delphacid planthoppers in the family Delphacidae. There are at least 10 described species in Kosswigianella.
Metadelphax is a genus of delphacid planthoppers in the family Delphacidae. There are at least 5 described species in Metadelphax.
Danepteryx is a genus of tropiduchid planthoppers in the family Tropiduchidae. There are about 6 described species in Danepteryx.
Delphacodes is a genus of delphacid planthoppers in the family Delphacidae. There are at least 230 described species in Delphacodes.
Laccocera is a genus of delphacid planthoppers in the family Delphacidae. There are about 10 described species in Laccocera.
Agalmatium flavescens is a species of planthopper belonging to the family Issidae, subfamily Issinae.
Euides is a genus of planthoppers belonging to the family Delphacidae.
