Megascelidini is a tribe of leaf beetles in the subfamily Eumolpinae. It contains two genera, Megascelis and Mariamela , which are found in the New World. Historically, the group was classified as a separate subfamily. [2] [3]
The Eumolpinae are a subfamily of the leaf beetles, or Chrysomelidae. It is one of the largest subfamilies of leaf beetles, including more than 500 genera and 7000 species. They are oval, and convex in form, and measure up to 10 mm in size. Typical coloration for this subfamily of beetles ranges from bright yellow to dark red. Many species are iridescent or brilliantly metallic blue or green in appearance.
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.
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.
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.
Megascelis is a genus of leaf beetles in the family Eumolpinae. It is known from both North and South America. There are around 140 described species in Megascelis.
Tymnes is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North America and Central America. There are at least nine described species in Tymnes.
Typophorus is a genus of leaf beetles in the subfamily Eumolpinae. There are at least 53 described species in Typophorus. Similar genera include Paria and Tijucana. Typophorus itself is probably polyphyletic.
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 antenna cleaners on the tibiae of the middle and hind legs. 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.
Semmiona is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa.
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.
Lamprosphaerus is a genus of leaf beetles in the subfamily Eumolpinae. They are found in Central America and South America.
Hylax is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Central America and South America.
Habrophora is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Central America, South America, and the West Indies. It is placed in the tribe Habrophorini with the related genus Psathyrocerus.
Psathyrocerus is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in South America. It is placed in the tribe Habrophorini with the related genus Habrophora.
Habrophorini is a tribe of leaf beetles in the subfamily Eumolpinae. It was established by Czech entomologist Jan Bechyné and his wife Bohumila Špringlová de Bechyné in 1969 for two genera, Habrophora and Psathyrocerus. They are distributed in the Neotropical realm.
Meroda is a genus of leaf beetles in the subfamily Eumolpinae. It is the only member of the tribe Merodini. It is distributed in the state of Amazonas in Brazil.
Hemydacnini is a tribe of leaf beetles in the subfamily Eumolpinae. It contains two genera, Hemydacne and Colasita, which are found in Madagascar.
