Xyleborinus exiguus, is a species of weevil widely distributed throughout the Old World tropics and introduced to African and South American countries.[1][2]

It is also introduced to West African countries such as Angola, Cameroon, Congo, Equatorial Guinea, Gabon, Ghana, Ivory Coast, Zaire as well as in Central American countries: Costa Rica, and Panamá.[3]

Description

This small, elongate-cylindrical beetle is about 1.8 to 2.0 mm long. This weevil can be identified by the declivital face with interstriae 2 which is unarmed by tubercles. Elytral apex is attenuate, with three pairs of large flattened tubercles. The declivital interstriae is flat, and the interstriae 2 is not impressed.[3][4]

A polyphagous species, it is found from many host plants.[1][5]
