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.
The subfamily Aphaeninae is a group of hemipteran insects, especially abundant and diverse in the tropics, in the family Fulgoridae, or "lanternflies".
The Ectrichodiinae are a subfamily of assassin bugs (Reduviidae) known for specializing on millipedes as prey. The group comprises more than 600 species in about 115 genera, making it a fairly large subfamily. The bugs are also known for their aposematic coloration, often brightly colored metallic blue, red, or yellow.
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.
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.
Lophopidae is a family of fulgoroid plant-hoppers with most species found in tropical South America and Asia.
Leptataspis is a genus of froghoppers belonging to the family Cercopidae.
Achilidae is a family of planthoppers, sometimes called "achilids" in the order Hemiptera. There are at least 520 described species in Achilidae.
Tropiduchinae is a subfamily of tropiduchid planthoppers in the family Tropiduchidae.
Dictyopharinae is a subfamily of dictyopharid planthoppers in the family Dictyopharidae. There more than 100 genera and 500 described species in Dictyopharinae.
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.
The Flatinae are a subfamily of planthoppers, erected by Maximilian Spinola in 1839. Genera have been recorded from all continents except Antarctica: especially in tropical and subtropical regions.
Tambiniini is a is a tribe of planthoppers in the subfamily Tropiduchinae, erected by George Kirkaldy in 1907. There are more than 60 species in genera mostly found in South- and South-East Asia, eastern Australia and the Pacific islands.
Tropiduchus is a genus of planthoppers, recorded from Africa and Malesia.
The Plectoderini are a large tribe of planthoppers in the family Achilidae, erected by Ronald Gordon Fennah in 1950. Genera have a world-wide distribution, but are hardly represented in Europe or northern Asia.
Eoscarta is a genus of froghopper (Cercopidae) with about 50 species distributed in the Oriental region. Species in the genus are identified by a combination of characters that include an elongated pubescent body, highly laterally compressed postclypeus, the hind tibia with a single lateral spur and genital characters of the males.
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.
