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]
