Genus of leaf beetles from Africa
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 .
