Syagrus buqueti (= Cryptocephalus calcaratus Fabricius, 1775) |
Syagrus is a genus of leaf beetles in the subfamily Eumolpinae. [2] They are known from the mainland of Africa. They are often attracted by plants in the family Malvaceae; [3] 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. [4]
Many species described from Madagascar were included in Syagrus by Jan Bechyně in the 1940s to 1960s. These species have been transferred to the related genus Pheloticus , restricting Syagrus to the mainland of Africa. [5] [2] [6] Many additional species of Syagrus described from mainland Africa have been transferred to other African Eumolpinae genera such as Afroeurydemus , Microsyagrus and Proliniscus . [5] [7] [6]
Species of Syagrus include the following: [2] [6]
Colasposoma is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa, Asia and Australia.
Syagrus calcaratus is a species of leaf beetle widely distributed across sub-Saharan Africa. It was first described by Johan Christian Fabricius in 1775, in his major work Systema entomologiae.
Syagrus puncticollis is a species of leaf beetle widely distributed across sub-Saharan Africa. It was first described by the German entomologist Edgar von Harold in 1877. Host plants for the species include Erythrophleum guineense.
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.
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.
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.
Proliniscus is a genus of leaf beetles in the subfamily Eumolpinae, found in Africa. Most of its species were originally placed in Liniscus or Syagrus.
Sarum is a genus of leaf beetles in the subfamily Eumolpinae, found in Africa. Most of its species were originally placed in Rhembastus.
Eurydemus is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa and Fiji.
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.
Microsyagrus is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa. Many of the species were formerly placed in Syagrus.
Pagria is a genus of leaf beetles in the subfamily Eumolpinae. It is known from Africa, Asia and Australia.
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.
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.
