Abstract

ABSTRACT In order to solve the affinities of the species of Isotes Weise, 1922, a detailed morphological comparative study was carried out based on type-species of Isotes and its junior synonym,Synbrotica Bechyné, 1956. Isotes tetraspilota (Baly, 1865) and Isotes borrei (Baly, 1889) had their morphology of mouthparts, endosternites, wings and both male and female genitalia compared by the first time. A new synonymy is established between Isotes borrei (Baly, 1889) and Isotes crucigera (Weise, 1916) syn. nov. based on external and genitalia morphology. New structures for Section Diabroticites Chapuis, 1875 are presented and discussed.
