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. [4]
The genus was first identified by the German entomologist Edgar von Harold in 1877 from species in Madagascar, Nyassa and Port Natal. [1] By 1914, 18 different species had already been recorded from Madagascar. In 1965, Brian J. Selman reduced the size of the genus by 45 species, transferring them to other genera such as Paraivongius , Massartia and Sarum . He also suggested that a revision of the Eumolpinae of Madagascar would produce a complete generic separation of the Madagascan and African species. [2] In 2006, it was suggested that a full revision of the genus is necessary. [4]

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.
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.
Llanomolpus is a genus of leaf beetles in the subfamily Eumolpinae. It contains only one species, Llanomolpus flavidus, which is known from Venezuela, though it was originally described from Colombia. The genus is related to Ischyrolampra and Agrosterna. The general appearance of the species resembles Chalcoplacis fulva.
Eurydemus is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa and Fiji.
Thysbina is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa. It was first established by the German entomologist Julius Weise in 1902, for several species from Colasposoma as well as three new species. According to Louis Jules Léon Burgeon in 1941, Thysbina is actually a synonym of Colasposoma, though this proposed synonymy has been ignored in later works.
Allocolaspis is a genus of leaf beetles in the subfamily Eumolpinae.
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.
Antitypona 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.
Chalcoplacis is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in South America.
Ledesmodina is a genus of leaf beetles in the subfamily Eumolpinae. It is found in Central America and South America.
