Bechyneia is a genus of leaf beetles in the subfamily Eumolpinae. [1] It contains only one species, Bechyneia spinosa, which is found in South Africa.
The genus and species were first described by the French entomologist Pierre Jolivet in 1950, and were originally placed in the subfamily Chrysomelinae. However, this placement was later found to be in error, as the genus actually belongs to the Eumolpinae. [2]
The genus is very similar to roughly sculptured species of Euryope ; according to unpublished information on the African Eumolpinae website, B. spinosa is likely a synonym of Euryope monstrosa . This synonymy was formalised by Stefano Zoia in 2024. [3] An association with the spilopyrine genus Cheiloxena was suggested by Jolivet in 1950, but this could not be seen by later authors. [4]
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.
Colasposoma is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa, Asia and Australia.
The Spilopyrinae are a small subfamily of the leaf beetles, or Chrysomelidae. They occur in Australia, New Guinea, New Caledonia and Chile. They were formerly considered a tribe of the subfamily Eumolpinae. The group was elevated to subfamily rank by C. A. M. Reid in 2000. However, some authors have criticised this placement, preferring to retain them within the Eumolpinae.
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.
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.
Dermoxanthus is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Africa.
Euryope is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Africa and the Arabian Peninsula.
Sarum is a genus of leaf beetles in the subfamily Eumolpinae, found in Africa. Most of its species were originally placed in Rhembastus.
Selmania is a genus of leaf beetles in the subfamily Eumolpinae, found in Africa. Most of the species in the genus were originally placed in Rhembastus.
Timentes is a genus of leaf beetles in the subfamily Eumolpinae. It contains only one species, Timentes camerunensis, from Cameroon and possibly Tanzania. It is closely related to Thysbina.
Eryxia is a genus of leaf beetles in the subfamily Eumolpinae. It is distributed in Africa and Western Asia.
Microeurydemus is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa and the Arabian Peninsula.
Lahejia is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa and Asia. It is related to Malegia.
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.
Pathius is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa and the Arabian Peninsula.
Euryopini is a tribe of leaf beetles in the subfamily Eumolpinae.
Bromiini is a tribe of leaf beetles in the subfamily Eumolpinae. The tribe contains approximately 120 genera, which are found worldwide. They are generally thought to be an artificial group, often with a subcylindrical prothorax without lateral ridges and covered with setae or scales.
