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.
Many species described from Madagascar were included in Syagrus by Jan BechynÃÂ in the 1940s to 1960s. These species have been transferred to the related genus Pheloticus, restricting Syagrus to the mainland of Africa. Many additional species of Syagrus described from mainland Africa have been transferred to other African Eumolpinae genera such as Afroeurydemus, Microsyagrus and Proliniscus.
