Eurydemus is a genus of leaf beetles in the subfamily Eumolpinae. [2] [3] It is known from Africa and Fiji.
The genus was first erected by the French entomologist Félicien Chapuis for a single species, Eurydemus insignis, reported from Australia and later Fiji. [4] This species was later found to be a junior synonym of Rhyparida grandis, which itself was originally reported from New Caledonia. However, both the records from Australia and New Caledonia are possibly erroneous. [5] [6]
In 1965, British entomologist Brian J. Selman revised the genus, transferring all African species in it seen by him to Afroeurydemus and other related African genera. He suggested that it was almost certain Eurydemus was restricted to Fiji. [7]

Colasposoma is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa, Asia and Australia.
Platycorynus is a genus of leaf beetles in the subfamily Eumolpinae. Species of the genus are found in Africa and Asia.
Colaspoides is a genus of leaf beetles in the subfamily Eumolpinae. It is one of the largest genera in the subfamily, containing over 260 species worldwide. It is an extant genus but there is at least one species, C. eocenicus, found in Baltic amber from the Upper Eocene of Russia, and the genus has also been reported from the Miocene of the Dominican Republic.
Rhembastus is a genus of leaf beetles in the subfamily Eumolpinae, native to Africa. Whilst the taxonomy of the genus is disputed, the genus has been suggested as a biological control agent for Bryophyllum delagoense in Australia.
Macrocoma is a genus of leaf beetles in the subfamily Eumolpinae. It contains about 100 species, which are found in tropical Africa, around the Mediterranean, on the Canary Islands, in western and central Asia, and in India.
Syagrus is a genus of leaf beetles in the subfamily Eumolpinae. They are known from the mainland of Africa. They are often attracted by plants in the family Malvaceae; Syagrus rugifrons and Syagrus calcaratus are pests of cotton. The larvae of Syagrus calcaratus attack the roots of the plant and cause it to wilt.
Afroeurydemus is a genus of leaf beetles in the subfamily Eumolpinae, found in Africa. The genus was separated from Eurydemus in 1965 by Brian J. Selman, who moved all African species of Eurydemus he had seen to this genus or related African genera and considered it likely that Eurydemus was restricted to Fiji. Many species were also originally placed in Syagrus.
Paraivongius is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Africa.
Pseudocolaspis is a genus of leaf beetles in the subfamily Eumolpinae. It contains about 80 species, which are found in tropical Africa.
Eumolpini is a tribe of leaf beetles in the subfamily Eumolpinae. It is the largest tribe in the subfamily, with approximately 170 genera found worldwide. Members of the tribe almost always have a longitudinal median groove on the pygidium, which possibly helps to keep the elytra locked at rest. They also generally have a subglabrous body, as well as appendiculate pretarsal claws.
Rhabdopterus is a genus of leaf beetles in the subfamily Eumolpinae. There are about 70 described species in Rhabdopterus from North and South America, eight of which are found north of Mexico. The Nearctic species may not be congeneric with the type species, which is South American.
Spintherophyta is a genus of leaf beetles in the subfamily Eumolpinae. Most species in the genus are found in Central and South America, but there are also a few North American species.
Typophorini is a tribe of leaf beetles in the subfamily Eumolpinae. The tribe contains approximately 100 genera, which are found worldwide. Members of the tribe are mainly characterized by notches on the tibiae of the middle and hind legs, which are sometimes referred to as antenna cleaners. They also generally have a subglabrous body, as well as bifid pretarsal claws.
Alethaxius is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed from Mexico to northern South America, and it is also found in the West Indies. The genus was originally named Aletes by Félicien Chapuis in 1874. However, this name was preoccupied by Aletes Carpenter, 1857, so the genus was renamed to Alethaxius by Édouard Lefèvre in 1885. According to Flowers (1996), it is very likely that Alethaxius is polyphyletic and represents at least three different genera.
Trichostola is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed on the Mascarene Islands. Some species placed in the genus have also been described from mainland Africa and Madagascar, but according to Jan Bechyné (1957) these actually belong to other genera. Additionally, some species described from Australia were placed in the genus by Julius Weise in 1923, but these are also considered to be misplaced.
Pheloticus is a genus of leaf beetles in the subfamily Eumolpinae. It is found in Madagascar. Many species had been previously placed in the related genus Syagrus by Jan Bechyně.
Lamprosphaerus is a genus of leaf beetles in the subfamily Eumolpinae. It is found in Central America and South America.
Ivongius is a genus of leaf beetles in the subfamily Eumolpinae. It is found in Madagascar.
Hylax is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Central America and South America.
