Abstract

Among eucalypt leaf beetles, Metaxyonycha angusta is a very important pest because it causes losses to the wood production in the Brazilian eucalypt plantations. This work deals to the morphologic character which allow sex determination in that insect specie. External morphologic characteristics, such as urosternite shapes and body measurements, were examined from 50 insects of each sex. Sex determination may be found out through examining the fifth urosternite. In males, there is a small clipping at the posterior edge of the fifth urosternite. Females have the posterior edge of that segment presenting a deeper notch
