A morphological examination was conducted on the digestive tract and the female reproductive system of the citrus weevil, Compsus sp. (Coleoptera: Curculionidae). The digestive tract of Compsus sp. showed a typical arrangement as described for other insects. Morphological differences, however, were found in the crop of the foregut, which exhibited several spine-like structures. At the midgut level, the anterior ventricle was divided into medium-size sacs and numerous gastric caecae projected into the posterior ventricle. The female reproductive system showed a structural arrangement common to individuals of the family Curculionidae.
