Zoraida is a large genus of planthoppers in the tribe Zoraidini of the family Derbidae. As of 2024, it comprises three subgenera and around 120 species. The species are found in tropical and some subtropical parts of Asia, Africa and parts of Australia and the western Pacific. [1] [2] [3] This page provides for each subgenus an overview of the species, their distribution records and other details. "Wing length" means the length of the forewing which have been converted in some cases from measurements of expanded forewings (wingspan) according to the formula <half of wingspan minus 10%>, derived from published illustrations.

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.
Brixia is a genus of cixiid planthopper that includes about 120 species. Most species are found in the Oriental region, and a few in the Afrotropical realm.
Achilidae is a family of planthoppers, sometimes called "achilids" in the order Hemiptera. There are at least 520 described species in Achilidae.
Derbinae is a subfamily of derbid planthoppers in the family Derbidae.
Dictyopharinae is a subfamily of dictyopharid planthoppers in the family Dictyopharidae. There more than 100 genera and 500 described species in Dictyopharinae.
Proutista moesta is a common species of planthopper from the family Derbidae, tribe Zoraidini. It is found in tropical parts of Asia from India to southern parts of China, some islands in the western Pacific, as well as in the Indian Ocean. There is also a record from eastern Africa, a possible recent introduction. P. moesta can be common on crops like oil palms, coconut palms, sugarcane and several cereals, where it sucks the sap from the plants. It is often regarded as a pest of these crops, a vector of phytoplasma diseases and a biosecurity risk in countries outside its distribution range. Males of P. moesta are smaller than females when measured from the tip of the head to the end of the forewings. The forewings alone have a length of around 6.1 mm for males or around 6.6 mm for females. The colour is predominantly black, but the legs, antennae, facial ridges and the rostrum are yellowish to light orange. The ridges on the mesonotum and the clypeus are whitish to light yellow and the body has scattered white dots. The black forewings have some clear patches, mainly along the costal margin and in the distal half between the hind margin and the media vein. When at rest, the insect raises its wings above the body and spreads them out at an angle of about 60°.
Tambinia is a genus of planthoppers (Hemiptera) in the family Tropiduchidae and typical of the tribe Tambiniini ; species are found in Australia and Southeast Asia.
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.
Rhotana is a large genus of planthoppers from the family Derbidae, tribe Rhotanini, with more than 70 species. Most species have been reported from the rainforests of Borneo, Indonesia and New Guinea, but the distribution of the genus extends over a much wider area in southern and south-eastern Asia, as far north as southern Japan and including parts of the Pacific islands as well as Australia. The species are the largest in the tribe Rhotanini, typically between 5–6 mm from head to the tip of the wings. The forewings frequently have striking patterns and colours, some species have also marks on the hind wings.
Saccharodite is a large genus of planthoppers from the family Derbidae, tribe Rhotanini, with more than 100 species. The largest number of species have been reported from Borneo, Indonesia, New Guinea and the Philippines, but the genus has a much wider distribution, ranging from Sri Lanka in the West, over southern parts of mainland Asia up to southern Japan in the North. Saccharodite is also found in other parts of the western Pacific like Micronesia, Fiji and New Caledonia, up to eastern parts of Australia, in the South as far as Tasmania. The adult hoppers are around 5 mm long from head to the tip of the forewings. They are characterized by their forewing venation. The forewings are usually glassy and bright red marks are common on the head and body, up to most parts except the wings being coloured bright red. When the insects are at rest, the wing surfaces form a common plane like in house flies.
Alara is a genus of small planthoppers from the family Derbidae, tribe Rhotanini, with more than 30 species. The species are found mainly in New Guinea, other parts of Indonesia, Borneo and the Philippines. However, some species have been also reported from Sri Lanka, parts of mainland Asia, Taiwan and Australia. The adult hoppers are around 4 mm long from head to the end of the wings. The forewings are nearly oval in outline with 5 broad costal cells that gradually decrease in length from the base to the tip of the wings. The antennae and the rostrum are longer than in other genera of Rhotanini. The forewings are often dark brown and lack any bright colours. However, there may be red marks on the head. When the insects are at rest, the wing surfaces form a common plane like in house flies.
Rhotanella is a small genus of planthoppers from the family Derbidae, tribe Rhotanini, with 8 species. The species are found in the Philippines, Indonesia, New Guinea, the Solomon Islands and southern China. The adult hoppers are between 4–6 mm long from head to the tip of the wings. They can be recognized by the shape and venation of their forewings which have a broad base and 5 very wide costal cells. Especially the first (basal) costal cell is very broad and has a width of about one quarter to one third of the width of the whole wing. The ridges on the sides of the face meet in front of the eyes. The profile of the head is also unusual for the tribe Rhotanini and has either an approximately rectangular or a somewhat triangular outline. The colour of the body is straw-coloured to light brown. The legs may be partly red or have red stripes. The forewings are brownish, but may have red marks in the costal cells. The forewings are carried in a roof-like position when the insects are at rest.
The Zoraidini is a group (tribe) of planthoppers in the family Derbidae. They are found in tropical and subtropical parts of Africa, Asia, Australia and in parts of the western Pacific. Almost 300 species in 27 genera are recognized. They are characterized by their long and narrow forewings and the short hind wings, usually not longer than half the length of the forewings and often even shorter. The forewings are typically around 8–10 mm long and the body is usually not more than half that length. In most species, the wings are raised when the insects are at rest, and are often spread out at an angle of about 45–90°. The head is compressed and the face is narrow in frontal view. The antennae are often long and the eyes cover about half the face. Like in other derbids, the adults suck the sap of plants while the nymphs live mainly in decaying organic matter. A few species are regarded as minor agricultural pests.
Zoraida is a large genus of planthoppers from the family Derbidae, tribe Zoraidini, with more than 100 species. These are widely distributed in the Old World tropics and in some subtropical parts of eastern Asia. In Africa, they are found mainly in the humid tropics of West Africa like Sierra Leone, the Ivory Coast, the Central African Republic, Nigeria or the Democratic Republic of Congo. However, Zoraida species have been also described from eastern Africa as far north as South Sudan and as far south as parts of South Africa. In Asia, the largest number of species have been described/reported from Indonesia, the Philippines, Taiwan and Sri Lanka, but species are also known as far south as northern Australia and as far north as the southern tip of far-eastern Russia. Like other species of the tribe Zoraidini, Zoraida species have long and narrow forewings and short hind wings. They can be identifies by the forewing venation and the structure of the head.
Proutista is a small genus of planthoppers from the family Derbidae, tribe Zoraidini, with 10 species, as of 2024. The type species, Proutista moesta is widely distributed and often very common, its distribution ranging from Tanzania in Africa, over some Indian Ocean islands and southern parts of western Asia to far eastern Asia and parts of the western Pacific. Seven of the remaining species are also found in tropical parts of Asia and only two additional species have been recorded from Africa, where Proutista fritillaris is the most common one. The species of Proutista are characterized by a combination of different features, mainly the shape and venation of the forewings, the size of the hind wings and the structure of the head and the antennae. On the forewings the media vein has 6 branches, none of them branching further into sub branches. The hind wings are about half as long as the forewings and have a rounded tip. The head has a narrow face (frons) and the antennae are rather short, much shorter than the face.
Diostrombus is a large genus of planthoppers from the family Derbidae, tribe Zoraidini, with more than 40 species. The large majority of species have been described from Africa and the Near East. However, a few species, including the type species, are found in southern and eastern parts of Asia. In Africa, the distribution range of Diostrombus species extends from the humid tropics of western Africa to many parts of eastern Africa, as far north as parts of Sudan and as far south as South Africa. Three species have been described from Yemen and the Iran. Like other species of the tribe Zoraidini, species of Diostrombus have long and narrow forewings and short hind wings. The main characteristic of Diostrombus is the forewing venation with the media vein having 6 branches which do not split further into sub branches. The hind wings are much shorter than half the forewing length and have a pointed tip. In profile the head is usually flat, but in some African species, the ridges on the sides of the face are extended in front of the antennae. The face is narrow. The antennae are short compared to other genera of the tribe Zoraidini, about half as long as the face.
Pamendanga is a genus of planthoppers from the family Derbidae, tribe Zoraidini, with 37 species, as of 2024. About two-thirds of the species, including the type species, are found in tropical and some subtropical parts of Asia, from Sri Lanka in the West to parts of Japan in the North-East and including the Philippines, Indonesia and New Guinea. The remaining species have been described from Africa, mainly from the humid tropics of West Africa, ranging from Sierra Leone and the Ivory Coast in the North to the Democratic Republic of Congo in the South. Some species are also known from eastern Africa. Like other species of the tribe Zoraidini, Pamendanga species have long and narrow forewings and short hind wings. They can be recognized by the forewing venation and the shape of the head and the antennae. On the forewing, the media vein has 6 branches and the 3rd branch forks further into 2 sub branches. The head has a flat profile and a narrow face with cylindrical antennae which are elongated but not longer than the face.
Lydda is a genus of planthoppers from the family Derbidae, tribe Zoraidini, with 21 species, as of 2024. The known distribution range of its species is restricted to parts of Queensland and the Northern Territory in Australia, to the island of New Guinea and to the island of Larat in south-eastern Indonesia. The type species, Lydda elongata, is mainly found in parts of Queensland and in New Guinea. In the past, the genus was often confused with the genus Proutista and a number of Lydda species have been originally described under Proutista. While species of Lydda and Proutista share a similar club-shaped outline of their forewings and a similar wing venation, there are significant differences between both genera in the forewing venation and the structure of the aedeagus in males. On the forewings, the media vein has only 5 branches, while Proutista species have 6 branches. In the type species, Lydda elongata, the eyes are unusually large and the head is very broad. The hind wings are about half as long as the forewings. Some species of Lydda have elaborate patterns on their body and forewings. For example, in live specimens of Lydda elongata, the body has a mixture of reddish brown and bluish patterns, while the forewings are brownish with darker spots. Species that have been previously described under the genus Lydda in Africa are now assigned to the genus Lyddastrombus.
Lyddastrombus is a small genus of planthoppers from the family Derbidae, tribe Zoraidini, currently (2024) with 8 African species. The morphology of the species is similar to those in the genus Lydda and most species have been originally described as part of Lydda. Lyddastrombus species can be recognized by the venation of their forewings and other features. The genus also shows similarities to the genera Diostrombus and Proutista, sharing with them the short antennae and a related forewing venation, where the media vein has 6 branches with none of them forking further into sub branches. However, Lyddastrombus species differ from both genera by their much broader head. Lyddastrombus was original described as a subgenus of Diostrombus, but it is now regarded as a separate genus, due to the broader head. The species of Lyddastrombus are found mainly in the tropical rainforests of West Africa from Sierra Leone over Nigeria to the Democratic Republic of the Congo, but have been also reported from parts of eastern Africa. Lyddastrombus hoppers have been frequently reported feeding on coconut and oil palms. In Mozambique, they were found to be carriers of a phytoplasma disease of coconut palms.
