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. It is distributed in Africa and Asia.
Colaspis is a genus of leaf beetles in the subfamily Eumolpinae. It is one of the largest genera in the subfamily, containing over 200 species, and it is known from both North and South America. A number of species from this genus are considered to be pests, such as the grape colaspis. Some species are known from the fossil record from the Eocene of Colorado in the United States.
Syagrus is a genus of leaf beetles in the subfamily Eumolpinae. They are known from the mainland of Africa as well as Madagascar. 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.
Paria is a genus of leaf beetles in the subfamily Eumolpinae. There are about 40 described species in Paria in North and South America, 19 of which are known north of Mexico. The genus is very similar to Typophorus.
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.
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.
Eurydemus is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa and Fiji.
Pheloticus is a genus of leaf beetles in the subfamily Eumolpinae. It is found in Madagascar.
Percolaspis is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in South America and Central America, though it has also been reported from southern Florida in the United States. It is associated with the plant families Rubiaceae and Fabaceae in Central America.
Callicolaspis is a genus of leaf beetles in the subfamily Eumolpinae. It is known from South America. It was formerly considered a synonym of Lycaste, but in 2003 it was restored as a separate genus.
Antitypona is a genus of leaf beetles in the subfamily Eumolpinae. They are found in Central America and South America.
Nodocolaspis is a genus of leaf beetles in the subfamily Eumolpinae. They are known from Central America and South America. The genus was first established by the Czech entomologist Jan Bechyné in 1949, as a relative of Nodonota containing species formerly placed in Colaspis.
Ivongius is a genus of leaf beetles in the subfamily Eumolpinae. They are found in Madagascar.
Chalcoplacis is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in South America.
